## 9.1 Multi-Replica Capability
If KisFlow needs to be used concurrently by multiple Goroutines while executing flows, it may require creating multiple flows with the same configuration to match multiple concurrent computation flows. Therefore, Flow needs the ability to create replicas. This chapter will implement this capability.
### 9.1.1 Adding Fork Interface to Flow
First, add a new interface `Fork()` to the Flow abstraction layer with the following prototype:
> kis-flow/kis/flow.go
```go
type Flow interface {
// Run schedules the Flow, sequentially dispatching and executing the Functions within the Flow
Run(ctx context.Context) error
// Link connects the Functions within the Flow according to the configuration file
Link(fConf *config.KisFuncConfig, fParams config.FParam) error
// CommitRow submits data to be executed to the Function layer of the Flow
CommitRow(row interface{}) error
// Input gets the input source data of the currently executing Function in the Flow
Input() common.KisRowArr
// GetName gets the name of the Flow
GetName() string
// GetThisFunction gets the currently executing Function
GetThisFunction() Function
// GetThisFuncConf gets the configuration of the currently executing Function
GetThisFuncConf() *config.KisFuncConfig
// GetConnector gets the Connector of the currently executing Function
GetConnector() (Connector, error)
// GetConnConf gets the configuration of the Connector of the currently executing Function
GetConnConf() (*config.KisConnConfig, error)
// GetConfig gets the configuration of the current Flow
GetConfig() *config.KisFlowConfig
// GetFuncConfigByName gets the configuration of the Function by name in the current Flow
GetFuncConfigByName(funcName string) *config.KisFuncConfig
// Next performs the Action for the next Function in the Flow
Next(acts ...ActionFunc) error
// GetCacheData gets the cached data of the current Flow
GetCacheData(key string) interface{}
// SetCacheData sets the cached data of the current Flow
SetCacheData(key string, value interface{}, Exp time.Duration)
// GetMetaData gets the temporary data of the current Flow
GetMetaData(key string) interface{}
// SetMetaData sets the temporary data of the current Flow
SetMetaData(key string, value interface{})
// GetFuncParam gets a key-value pair of the default parameters for the currently executing Function in the Flow
GetFuncParam(key string) string
// GetFuncParamAll gets all key-value pairs of the default parameters for the currently executing Function in the Flow
GetFuncParamAll() config.FParam
// +++++++++++++++++++++++++
// Fork gets a deep copy of the Flow
Fork(ctx context.Context) Flow
}
```
`Fork()` will clone a new KisFlow instance based on an existing KisFlow instance, creating a resource-isolated but identically configured KisFlow instance. The implementation method is as follows:
> kis-flow/flow/kis_flow.go
```go
// Fork gets a deep copy of the Flow
func (flow *KisFlow) Fork(ctx context.Context) kis.Flow {
config := flow.Conf
// Create a new Flow using the previous configuration
newFlow := NewKisFlow(config)
for _, fp := range flow.Conf.Flows {
if _, ok := flow.funcParams[flow.Funcs[fp.FuncName].GetId()]; !ok {
// The current Function has no Params configured
newFlow.Link(flow.Funcs[fp.FuncName].GetConfig(), nil)
} else {
// The current Function has Params configured
newFlow.Link(flow.Funcs[fp.FuncName].GetConfig(), fp.Params)
}
}
log.Logger().DebugFX(ctx, "=====>Flow Fork, oldFlow.funcParams = %+v\n", flow.funcParams)
log.Logger().DebugFX(ctx, "=====>Flow Fork, newFlow.funcParams = %+v\n", newFlow.GetFuncParamsAllFuncs())
return newFlow
}
```
In `Fork()`, a new KisFlow instance is created based on the configuration information of the existing flow, and the associated Params and other configuration information are copied along with it. Finally, the newly created Functions are linked to the new Flow using `Link()`.
To facilitate debugging, a new interface `GetFuncParamsAllFuncs()` has been added to the Flow to print the information of all `FuncParams`. The implementation method is as follows:
> kis-flow/kis/flow.go
```go
type Flow interface {
// ... ...
// ... ...
// GetFuncParamsAllFuncs retrieves all key-value pairs of the FuncParams for all Functions in the Flow
GetFuncParamsAllFuncs() map[string]config.FParam
// ... ...
}
```
> kis-flow/flow/kis_flow_data.go
```go
// GetFuncParamsAllFuncs retrieves all key-value pairs of the FuncParams for all Functions in the Flow
func (flow *KisFlow) GetFuncParamsAllFuncs() map[string]config.FParam {
flow.fplock.RLock()
defer flow.fplock.RUnlock()
return flow.funcParams
}
```
## 9.2 Unit Testing
Next, we will test the Fork capability with the following unit test code:
> kis-flow/test/kis_fork_test.go
```go
func TestForkFlow(t *testing.T) {
ctx := context.Background()
// 0. Register Function callback businesses
kis.Pool().FaaS("funcName1", faas.FuncDemo1Handler)
kis.Pool().FaaS("funcName2", faas.FuncDemo2Handler)
kis.Pool().FaaS("funcName3", faas.FuncDemo3Handler)
// 0. Register ConnectorInit and Connector callback businesses
kis.Pool().CaaSInit("ConnName1", caas.InitConnDemo1)
kis.Pool().CaaS("ConnName1", "funcName2", common.S, caas.CaasDemoHanler1)
// 1. Load configuration files and build Flow
if err := file.ConfigImportYaml("/Users/tal/gopath/src/kis-flow/test/load_conf/"); err != nil {
panic(err)
}
// 2. Get Flow
flow1 := kis.Pool().GetFlow("flowName1")
flow1Clone1 := flow1.Fork(ctx)
// 3. Submit original data
_ = flow1Clone1.CommitRow("This is Data1 from Test")
_ = flow1Clone1.CommitRow("This is Data2 from Test")
_ = flow1Clone1.CommitRow("This is Data3 from Test")
// 4. Execute flow1
if err := flow1Clone1.Run(ctx); err != nil {
panic(err)
}
}
```
First, we create an instance of the flow `flowName1` and then get `flowClone1` using `Fork()`. After that, we execute the scheduling process of `flowClone1`.
Navigate to the `kis-flow/test/` directory and execute:
```bash
go test -test.v -test.paniconexit0 -test.run TestForkFlow
```
The result is as follows:
```bash
=== RUN TestForkFlow

## 8.1 Flow Cache - Data Stream Caching
KisFlow also provides shared caching in stream computing, using a simple local cache for developers to use as needed. For third-party local cache technology dependencies, refer to: https://github.com/patrickmn/go-cache.
### 8.1.1 go-cache
#### (1) Installation
```bash
go get github.com/patrickmn/go-cache
```
#### (2) Usage
```go
import (
"fmt"
"github.com/patrickmn/go-cache"
"time"
)
func main() {
// Create a cache with a default expiration time of 5 minutes, and which
// purges expired items every 10 minutes
c := cache.New(5*time.Minute, 10*time.Minute)
// Set the value of the key "foo" to "bar", with the default expiration time
c.Set("foo", "bar", cache.DefaultExpiration)
// Set the value of the key "baz" to 42, with no expiration time
// (the item won't be removed until it is re-set, or removed using
// c.Delete("baz")
c.Set("baz", 42, cache.NoExpiration)
// Get the string associated with the key "foo" from the cache
foo, found := c.Get("foo")
if found {
fmt.Println(foo)
}
// Since Go is statically typed, and cache values can be anything, type
// assertion is needed when values are being passed to functions that don't
// take arbitrary types, (i.e. interface{}). The simplest way to do this for
// values which will only be used once--e.g. for passing to another
// function--is:
foo, found := c.Get("foo")
if found {
MyFunction(foo.(string))
}
// This gets tedious if the value is used several times in the same function.
// You might do either of the following instead:
if x, found := c.Get("foo"); found {
foo := x.(string)
// ...
}
// or
var foo string
if x, found := c.Get("foo"); found {
foo = x.(string)
}
// ...
// foo can then be passed around freely as a string
// Want performance? Store pointers!
c.Set("foo", &MyStruct, cache.DefaultExpiration)
if x, found := c.Get("foo"); found {
foo := x.(*MyStruct)
// ...
}
}
```
For detailed reference: https://github.com/patrickmn/go-cache
### 8.1.2 KisFlow Integration with go-cache
#### (1) Flow Provides Abstract Interface
Flow provides interfaces for cache operations as follows:
> kis-flow/kis/flow.go
```go
type Flow interface {
// Run schedules the Flow, sequentially scheduling and executing Functions within the Flow
Run(ctx context.Context) error
// Link connects Functions within the Flow according to the configuration file
Link(fConf *config.KisFuncConfig, fParams config.FParam) error
// CommitRow submits Flow data to the Function layer about to be executed
CommitRow(row interface{}) error
// Input gets the input source data for the currently executing Function in the Flow
Input() common.KisRowArr
// GetName gets the name of the Flow
GetName() string
// GetThisFunction gets the currently executing Function
GetThisFunction() Function
// GetThisFuncConf gets the configuration of the currently executing Function
GetThisFuncConf() *config.KisFuncConfig
// GetConnector gets the Connector of the currently executing Function
GetConnector() (Connector, error)
// GetConnConf gets the configuration of the Connector for the currently executing Function
GetConnConf() (*config.KisConnConfig, error)
// GetConfig gets the configuration of the current Flow
GetConfig() *config.KisFlowConfig
// GetFuncConfigByName gets the configuration of the Function by its name
GetFuncConfigByName(funcName string) *config.KisFuncConfig
// Next advances the currently executing Function to the next Function with specified Action
Next(acts ...ActionFunc) error
// ++++++++++++++++++++++++++++++++++++++++
// GetCacheData gets the cache data of the current Flow
GetCacheData(key string) interface{}
// SetCacheData sets the cache data of the current Flow
SetCacheData(key string, value interface{}, Exp time.Duration)
}
```
`SetCacheData()` sets the local cache, with Exp as the expiration time. If Exp is 0, it is permanent.
`GetCacheData()` reads the local cache.
#### (2) Providing Constants
Provide some constants related to cache expiration time.
> kis-flow/common/const.go
```go
// cache
const (
// DeFaultFlowCacheCleanUp is the default cache cleanup interval for Flow objects in KisFlow, in minutes
DeFaultFlowCacheCleanUp = 5 // in minutes
// DefaultExpiration is the default GoCache time, permanently saved
DefaultExpiration time.Duration = 0
)
```
#### (3) Adding and Initializing Members in KisFlow
> kis-flow/flow/kis_flow.go
```go
// KisFlow represents the context environment for stream computing
type KisFlow struct {
// ... ...
// ... ...
// Local cache for the flow
cache *cache.Cache // Temporary cache context environment for Flow
}
// NewKisFlow creates a new KisFlow
func NewKisFlow(conf *config.KisFlowConfig) kis.Flow {
flow := new(KisFlow)
// ... ...
// ... ...
// Initialize local cache
flow.cache = cache.New(cache.NoExpiration, common.DeFaultFlowCacheCleanUp*time.Minute)
return flow
}
```
#### (4) Implementing the Interface
Finally, implement the two interfaces for cache read and write operations as follows:
> kis-flow/flow/kis_flow_data.go
```go
func (flow *KisFlow) GetCacheData(key string) interface{} {
if data, found := flow.cache.Get(key); found {
return data
}
return nil
}
func (flow *KisFlow) SetCacheData(key string, value interface{}, Exp time.Duration) {
if Exp == common.DefaultExpiration {
flow.cache.Set(key, value, cache.DefaultExpiration)
} else {
flow.cache.Set(key, value, Exp)
}
}
```
## 8.2 MetaData Temporary Cache Parameters
MetaData is defined as a `map[string]interface{}` structure available at each level of Flow, Function, and Connector to store temporary data. The lifespan of this data is consistent with the lifespan of each instance.
### 8.2.1 Adding MetaData to Flow
First, add the `metaData map[string]interface{}` member and corresponding read-write lock to KisFlow.
> kis-flow/flow/kis_flow.go
```go
// KisFlow represents the context environment throughout the entire stream computing
type KisFlow struct {
// ... ...
// ... ...
// +++++++++++++++++++++++++++++++++++++++++++
// metaData for the flow
metaData map[string]interface{} // Custom temporary data for Flow
mLock sync.RWMutex // Read-write lock to manage metaData
}
```
Also, initialize the `metaData` member in the KisFlow constructor as follows:
> kis-flow/flow/kis_flow.go
```go
// NewKisFlow creates a KisFlow
func NewKisFlow(conf *config.KisFlowConfig) kis.Flow {
flow := new(KisFlow)
// ... ...
// ... ...
// ++++++++++++++++++++++++++++++++++++++
// Initialize temporary data
flow.metaData = make(map[string]interface{})
return flow
}
```
Next, add the read and write interfaces for MetaData to the Flow as follows:
> kis-flow/kis/flow.go
```go
type Flow interface {
// Run schedules the Flow, sequentially scheduling and executing Functions within the Flow
Run(ctx context.Context) error
// Link connects Functions within the Flow according to the configuration file
Link(fConf *config.KisFuncConfig, fParams config.FParam) error
// CommitRow submits Flow data to the Function layer about to be executed
CommitRow(row interface{}) error
// Input gets the input source data for the currently executing Function in the Flow
Input() common.KisRowArr
// GetName gets the name of the Flow
GetName() string
// GetThisFunction gets the currently executing Function
GetThisFunction() Function
// GetThisFuncConf gets the configuration of the currently executing Function
GetThisFuncConf() *config.KisFuncConfig
// GetConnector gets the Connector of the currently executing Function
GetConnector() (Connector, error)
// GetConnConf gets the configuration of the Connector for the currently executing Function
GetConnConf() (*config.KisConnConfig, error)
// GetConfig gets the configuration of the current Flow
GetConfig() *config.KisFlowConfig
// GetFuncConfigByName gets the configuration of the Function by its name
GetFuncConfigByName(funcName string) *config.KisFuncConfig
// Next advances the currently executing Function to the next Function with specified Action
Next(acts ...ActionFunc) error
// GetCacheData gets the cache data of the current Flow
GetCacheData(key string) interface{}
// SetCacheData sets the cache data of the current Flow
SetCacheData(key string, value interface{}, Exp time.Duration)
// ++++++++++++++++++++++++++++
// GetMetaData gets the temporary data of the current Flow
GetMetaData(key string) interface{}
// SetMetaData sets the temporary data of the current Flow
SetMetaData(key string, value interface{})
}
```
Define the `GetMetaData()` and `SetMetaData()` interfaces for reading and writing respectively. Finally, implement these interfaces as follows:
> kis-flow/flow/kis_flow_data.go
```go
// GetMetaData retrieves the temporary data of the current Flow object
func (flow *KisFlow) GetMetaData(key string) interface{} {
flow.mLock.RLock()
defer flow.mLock.RUnlock()
data, ok := flow.metaData[key]
if !ok {
return nil
}
return data
}
// SetMetaData sets the temporary data of the current Flow object
func (flow *KisFlow) SetMetaData(key string, value interface{}) {
flow.mLock.Lock()
defer flow.mLock.Unlock()
flow.metaData[key] = value
}
```
### 8.2.2 Adding MetaData to Function
First, add the `metaData` member to `BaseFunction` as follows:
> kis-flow/function/kis_base_function.go
```go
type BaseFunction struct {
// Id, KisFunction instance ID, used to distinguish different instance objects within KisFlow
Id string
Config *config.KisFuncConfig
// flow
flow kis.Flow // Context environment KisFlow
// connector
connector kis.Connector
// ++++++++++++++++++++++++
// Custom temporary data for Function
metaData map[string]interface{}
// Read-write lock to manage metaData
mLock sync.RWMutex
// link
N kis.Function // Next stream computing Function
P kis.Function // Previous stream computing Function
}
```
In the Function constructor, each specific Function needs a constructor to initialize the `metaData` member. The changes are as follows:
> kis-flow/function/kis_base_function.go
```go
func NewKisFunction(flow kis.Flow, config *config.KisFuncConfig) kis.Function {
var f kis.Function
// Factory produces generalized objects
// ++++++++++++++
switch common.KisMode(config.FMode) {
case common.V:
f = NewKisFunctionV() // +++
case common.S:
f = NewKisFunctionS() // +++
case common.L:
f = NewKisFunctionL() // +++
case common.C:
f = NewKisFunctionC() // +++
case common.E:
f = NewKisFunctionE() // +++
default:
// LOG ERROR
return nil
}
// Generate random unique instance ID
f.CreateId()
// Set basic information properties
if err := f.SetConfig(config); err != nil {
panic(err)
}
// Set Flow
if err := f.SetFlow(flow); err != nil {
panic(err)
}
return f
}
```
Each constructor is as follows:
> kis-flow/function/kis_function_c.go
```go
func NewKisFunctionC() kis.Function {
f := new(KisFunctionC)
// Initialize metaData
f.metaData = make(map[string]interface{})
return f
}
```
> kis-flow/function/kis_function_v.go
```go
func NewKisFunctionV() kis.Function {
f := new(KisFunctionV)
// Initialize metaData
f.metaData = make(map[string]interface{})
return f
}
```
> kis-flow/function/kis_function_e.go
```go
func NewKisFunctionE() kis.Function {
f := new(KisFunctionE)
// Initialize metaData
f.metaData = make(map[string]interface{})
return f
}
```
> kis-flow/function/kis_function_s.go
```go
func NewKisFunctionS() kis.Function {
f := new(KisFunctionS)
// Initialize metaData
f.metaData = make(map[string]interface{})
return f
}
```
> kis-flow/function/kis_function_l.go
```go
func NewKisFunctionL() kis.Function {
f := new(KisFunctionL)
// Initialize metaData
f.metaData = make(map[string]interface{})
return f
}
```
Next, add interfaces to access the metaData member in the Function abstraction layer as follows:
```go
type Function interface {
// Call executes the stream computing logic
Call(ctx context.Context, flow Flow) error
// SetConfig configures the strategy for the current Function instance
SetConfig(s *config.KisFuncConfig) error
// GetConfig retrieves the configuration strategy of the current Function instance
GetConfig() *config.KisFuncConfig
// SetFlow sets the Flow instance that the current Function instance depends on
SetFlow(f Flow) error
// GetFlow retrieves the Flow instance that the current Function instance depends on
GetFlow() Flow
// AddConnector adds a Connector to the current Function instance
AddConnector(conn Connector) error
// GetConnector retrieves the Connector associated with the current Function instance
GetConnector() Connector
// CreateId generates a random instance KisID for the current Function instance
CreateId()
// GetId retrieves the FID of the current Function
GetId() string
// GetPrevId retrieves the FID of the previous Function node of the current Function
GetPrevId() string
// GetNextId retrieves the FID of the next Function node of the current Function
GetNextId() string
// Next returns the next layer computing stream Function, or nil if it is the last layer
Next() Function
// Prev returns the previous layer computing stream Function, or nil if it is the last layer
Prev() Function
// SetN sets the next Function instance
SetN(f Function)
// SetP sets the previous Function instance
SetP(f Function)
// ++++++++++++++++++++++++++++++++++
// GetMetaData retrieves the temporary data of the current Function
GetMetaData(key string) interface{}
// SetMetaData sets the temporary data of the current Function
SetMetaData(key string, value interface{})
}
```
Implement the above two interfaces in the BaseFunction.
> kis-flow/function/kis_base_function.go
```go
// GetMetaData retrieves the temporary data of the current Function
func (base *BaseFunction) GetMetaData(key string) interface{} {
base.mLock.RLock()
defer base.mLock.RUnlock()
data, ok := base.metaData[key]
if !ok {
return nil
}
return data
}
// SetMetaData sets the temporary data of the current Function
func (base *BaseFunction) SetMetaData(key string, value interface{}) {
base.mLock.Lock()
defer base.mLock.Unlock()
base.metaData[key] = value
}
```
### 8.2.3 Adding MetaData to Connector
First, add the `metaData` member to `KisConnector` as follows:
> kis-flow/conn/kis_connector.go
```go
type KisConnector struct {
// Connector ID
CId string
// Connector Name
CName string
// Connector Config
Conf *config.KisConnConfig
// Connector Init
onceInit sync.Once
// ++++++++++++++
// Custom temporary data for KisConnector
metaData map[string]interface{}
// Read-write lock to manage metaData
mLock sync.RWMutex
}
// NewKisConnector creates a KisConnector based on the configuration strategy
func NewKisConnector(config *config.KisConnConfig) *KisConnector {
conn := new(KisConnector)
conn.CId = id.KisID(common.KisIdTypeConnector)
conn.CName = config.CName
conn.Conf = config
// +++++++++++++++++++++++++++++++++++
conn.metaData = make(map[string]interface{})
return conn
}
```
Initialize `metaData` in the constructor.
Next, add interfaces to access and set MetaData in the Connector abstraction layer as follows:
> kis-flow/kis/connector.go
```go
type Connector interface {
// Init initializes the links of the storage engine associated with the Connector
Init() error
// Call invokes the read and write operations of the external storage logic of the Connector
Call(ctx context.Context, flow Flow, args interface{}) error
// GetId retrieves the ID of the Connector
GetId() string
// GetName retrieves the name of the Connector
GetName() string
// GetConfig retrieves the configuration information of the Connector
GetConfig() *config.KisConnConfig
// GetMetaData retrieves the temporary data of the current Connector
// +++++++++++++++++++++++++++++++
GetMetaData(key string) interface{}
// SetMetaData sets the temporary data of the current Connector
SetMetaData(key string, value interface{})
}
```
Finally, implement the above two interfaces in `KisConnector` as follows:
> kis-flow/conn/kis_connector.go
```go
// GetMetaData retrieves the temporary data of the current Connector
func (conn *KisConnector) GetMetaData(key string) interface{} {
conn.mLock.RLock()
defer conn.mLock.RUnlock()
data, ok := conn.metaData[key]
if !ok {
return nil
}
return data
}
// SetMetaData sets the temporary data of the current Connector
func (conn *KisConnector) SetMetaData(key string, value interface{}) {
conn.mLock.Lock()
defer conn.mLock.Unlock()
conn.metaData[key] = value
}
```
## 8.3 Configuration File Parameters
KisFlow allows developers to define default parameters (Params) for configuring Flow, Function, Connector, etc., in the configuration file. Here are some examples:
Function:
```yaml
kistype: func
fname: funcName1
fmode: Verify
source:
name: Official Account Douyin Mall Order Data
must:
- order_id
- user_id
option:
default_params:
default1: funcName1_param1
default2: funcName1_param2
```
Flow:
```yaml
kistype: flow
status: 1
flow_name: flowName1
flows:
- fname: funcName1
params:
myKey1: flowValue1-1
myKey2: flowValue1-2
- fname: funcName2
params:
myKey1: flowValue2-1
myKey2: flowValue2-2
- fname: funcName3
params:
myKey1: flowValue3-1
myKey2: flowValue3-2
```
Connector:
```yaml
kistype: conn
cname: ConnName1
addrs: '0.0.0.0:9988,0.0.0.0:9999,0.0.0.0:9990'
type: redis
key: redis-key
params:
args1: value1
args2: value2
load: null
save:
- funcName2
```
Developers can provide Params for each defined module. Params provided in Flow will also be added to the Functions.
In the previous steps, we already read these parameters into each module's memory, but we did not expose an interface for developers.
### 8.3.1 Adding Param Retrieval Interface to Flow
First, we provide an interface for Flow to query Params:
> kis-flow/kis/flow.go
```go
type Flow interface {
// ... ...
// ... ...
// GetFuncParam retrieves a key-value pair of the default parameters for the currently executing Function in the Flow
GetFuncParam(key string) string
// GetFuncParamAll retrieves all key-value pairs of the default parameters for the currently executing Function in the Flow
GetFuncParamAll() config.FParam
}
```
Implementation:
> kis-flow/flow/kis_flow_data.go
```go
// GetFuncParam retrieves a key-value pair of the default parameters for the currently executing Function in the Flow
func (flow *KisFlow) GetFuncParam(key string) string {
flow.fplock.RLock()
defer flow.fplock.RUnlock()
if param, ok := flow.funcParams[flow.ThisFunctionId]; ok {
if value, vok := param[key]; vok {
return value
}
}
return ""
}
// GetFuncParamAll retrieves all key-value pairs of the default parameters for the currently executing Function in the Flow
func (flow *KisFlow) GetFuncParamAll() config.FParam {
flow.fplock.RLock()
defer flow.fplock.RUnlock()
param, ok := flow.funcParams[flow.ThisFunctionId]
if !ok {
return nil
}
return param
}
```
`GetFuncParam()` and `GetFuncParamAll()` retrieve a single key or all parameters respectively, but both fetch the Params for the currently executing Function.
### 8.3.2 Unit Testing
We add some parameters to each Function in `flowName1`.
> kis-flow/test/load_conf/flow-FlowName1.yml
```yaml
kistype: flow
status: 1
flow_name: flowName1
flows:
- fname: funcName1
params:
myKey1: flowValue1-1
myKey2: flowValue1-2
- fname: funcName2
params:
myKey1: flowValue2-1
myKey2: flowValue2-2
- fname: funcName3
params:
myKey1: flowValue3-1
myKey2: flowValue3-2
```
Then configure some default custom parameters for each associated Function:
> kis-flow/test/load_conf/func/func-FuncName1.yml
```yaml
kistype: func
fname: funcName1
fmode: Verify
source:
name: Official Account Douyin Mall Order Data
must:
- order_id
- user_id
option:
default_params:
default1: funcName1_param1
default2: funcName1_param2
```
> kis-flow/test/load_conf/func/func-FuncName2.yml
```yaml
kistype: func
fname: funcName2
fmode: Save
source:
name: User Order Error Rate
must:
- order_id
- user_id
option:
cname: ConnName1
default_params:
default1: funcName2_param1
default2: funcName2_param2
```
> kis-flow/test/load_conf/func/func-FuncName3.yml
```yaml
kistype: func
fname: funcName3
fmode: Calculate
source:
name: User Order Error Rate
must:
- order_id
- user_id
option:
default_params:
default1: funcName3_param1
default2: funcName3_param2
```
We also configure some Param parameters for the Connector associated with `FuncName2`:
> kis-flow/test/load_conf/conn/conn-ConnName1.yml
```yaml
kistype: conn
cname: ConnName1
addrs: '0.0.0.0:9988,0.0.0.0:9999,0.0.0.0:9990'
type: redis
key: redis-key
params:
args1: value1
args2: value2
load: null
save:
- funcName2
```
To verify that our configuration parameters can be correctly retrieved during the execution of Functions, we modified each Function and Connector business function to print their Params:
> kis-flow/test/faas/faas_demo1.go
```go
func FuncDemo1Handler(ctx context.Context, flow kis.Flow) error {
fmt.Println("---> Call funcName1Handler ----")
// ++++++++++++++++
fmt.Printf("Params = %+v\n", flow.GetFuncParamAll())
for index, row := range flow.Input() {
// Print data
str := fmt.Sprintf("In FuncName = %s, FuncId = %s, row = %s", flow.GetThisFuncConf().FName, flow.GetThisFunction().GetId(), row)
fmt.Println(str)
// Calculate result data
resultStr := fmt.Sprintf("data from funcName[%s], index = %d", flow.GetThisFuncConf().FName, index)
// Commit result data
_ = flow.CommitRow(resultStr)
}
return nil
}
```
> kis-flow/test/faas/faas_demo2.go
```go
func FuncDemo2Handler(ctx context.Context, flow kis.Flow) error {
fmt.Println("---> Call funcName2Handler ----")
// ++++++++++++++++
fmt.Printf("Params = %+v\n", flow.GetFuncParamAll())
for index, row := range flow.Input() {
str := fmt.Sprintf("In FuncName = %s, FuncId = %s, row = %s", flow.GetThisFuncConf().FName, flow.GetThisFunction().GetId(), row)
fmt.Println(str)
conn, err := flow.GetConnector()
if err != nil {
log.Logger().ErrorFX(ctx, "FuncDemo2Handler(): GetConnector err = %s\n", err.Error())
return err
}
if conn.Call(ctx, flow, row) != nil {
log.Logger().ErrorFX(ctx, "FuncDemo2Handler(): Call err = %s\n", err.Error())
return err
}
// Calculate result data
resultStr := fmt.Sprintf("data from funcName[%s], index = %d", flow.GetThisFuncConf().FName, index)
// Commit result data
_ = flow.CommitRow(resultStr)
}
return nil
}
```
> kis-flow/test/faas/faas_demo3.go
```go
func FuncDemo3Handler(ctx context.Context, flow kis.Flow) error {
fmt.Println("---> Call funcName3Handler ----")
// ++++++++++++++++
fmt.Printf("Params = %+v\n", flow.GetFuncParamAll())
for _, row := range flow.Input() {
str := fmt.Sprintf("In FuncName = %s, FuncId = %s, row = %s", flow.GetThisFuncConf().FName, flow.GetThisFunction().GetId(), row)
fmt.Println(str)
}
return nil
}
```
> kis-flow/test/caas/caas_demo1.go
```go
func CaasDemoHanler1(ctx context.Context, conn kis.Connector, fn kis.Function, flow kis.Flow, args interface{}) error {
fmt.Printf("===> In CaasDemoHanler1: flowName: %s, cName:%s, fnName:%s, mode:%s\n",
flow.GetName(), conn.GetName(), fn.GetConfig().FName, fn.GetConfig().FMode)
// +++++++++++
fmt.Printf("Params = %+v\n", conn.GetConfig().Params)
fmt.Printf("===> Call Connector CaasDemoHanler1, args from funciton: %s\n", args)
return nil
}
```
Finally, we write the unit test cases:
> kis-flow/test/kis_params_test.go
```go
package test
import (
"context"
"kis-flow/common"
"kis-flow/file"
"kis-flow/kis"
"kis-flow/test/caas"
"kis-flow/test/faas"
"testing"
)
func TestParams(t *testing.T) {
ctx := context.Background()
// 0. Register Function callback businesses
kis.Pool().FaaS("funcName1", faas.FuncDemo1Handler)
kis.Pool().FaaS("funcName2", faas.FuncDemo2Handler)
kis.Pool().FaaS("funcName3", faas.FuncDemo3Handler)
// 0. Register ConnectorInit and Connector callback businesses
kis.Pool().CaaSInit("ConnName1", caas.InitConnDemo1)
kis.Pool().CaaS("ConnName1", "funcName2", common.S, caas.CaasDemoHanler1)
// 1. Load configuration files and build Flow
if err := file.ConfigImportYaml("/Users/tal/gopath/src/kis-flow/test/load_conf/"); err != nil {
panic(err)
}
// 2. Get Flow
flow1 := kis.Pool().GetFlow("flowName1")
// 3. Submit original data
_ = flow1.CommitRow("This is Data1 from Test")
_ = flow1.CommitRow("This is Data2 from Test")
_ = flow1.CommitRow("This is Data3 from Test")
// 4. Execute flow1
if err := flow1.Run(ctx); err != nil {
panic(err)
}
}
```
Navigate to the `kis-flow/test/` directory and execute:
```bash
go test -test.v -test.paniconexit0 -test.run TestParams
```
```bash
=== RUN TestParams
....
....
---> Call funcName1Handler ----
Params = map[default1:funcName1_param1 default2:funcName1_param2 myKey1:flowValue1-1 myKey2:flowValue1-2]
...
...
---> Call funcName2Handler ----
Params = map[default1:funcName2_param1 default2:funcName2_param2 myKey1:flowValue2-1 myKey2:flowValue2-2]
...
...
===> In CaasDemoHanler1: flowName: flowName1, cName:ConnName1, fnName:funcName2, mode:Save
Params = map[args1:value1 args2:value2]
...
...
===> In CaasDemoHanler1: flowName: flowName1, cName:ConnName1, fnName:funcName2, mode:Save
Params = map[args1:value1 args2:value2]
...
...
===> In CaasDemoHanler1: flowName: flowName1, cName:ConnName1, fnName:funcName2, mode:Save
Params = map[args1:value1 args2:value2]
...
...
---> Call funcName3Handler ----
Params = map[default1:funcName3_param1 default2:funcName3_param2 myKey1:flowValue3-1 myKey2:flowValue3-2]
...
...
--- PASS: TestParams (0.01s)
PASS
ok kis-flow/test 0.433s
```
As we can see, we can now correctly retrieve the Params configuration parameters at each level.

1,898,325 | Using Domain-Driven Design to to Create Microservice App | Creating scalable and maintainable applications remains a constant challenge in the software... | 0 | 2024-06-24T07:18:01 | https://dev.to/eugene-zimin/leveraging-domain-driven-design-for-application-design-58e2 | softwareengineering, architecture, microservices, eventdriven | Creating scalable and maintainable applications remains a constant challenge in the software development industry. As digital ecosystems grow more complex and user demands evolve rapidly, developers face increasing pressure to build systems that can adapt and expand seamlessly.
Scalability presents a multifaceted challenge. Applications must handle growing user bases, increasing data volumes, and expanding feature sets without compromising performance. This requires careful architectural decisions, efficient resource utilization, and the ability to distribute workloads effectively across multiple servers or cloud instances.
Maintainability, on the other hand, focuses on the long-term health of the codebase. As applications grow in complexity, keeping the code clean, understandable, and easily modifiable becomes crucial. This involves creating modular designs, adhering to coding standards, and implementing robust testing strategies. A maintainable codebase allows for faster bug fixes, easier feature additions, and smoother onboarding of new team members.
The intersection of scalability and maintainability often leads to trade-offs. Highly optimized systems for scalability may sacrifice code readability, while overly modular designs for maintainability might introduce performance overhead. Striking the right balance requires deep domain knowledge, technical expertise, and a forward-thinking approach to software design.
The rapid pace of technological change adds another layer of complexity. Developers must create systems that not only meet current needs but also remain flexible enough to incorporate future technologies and methodologies. This forward-looking approach is essential in preventing technical debt and ensuring the longevity of the application.
Rapid pace of technological change adds another layer of complexity. Developers must create systems that not only meet current needs but also remain flexible enough to incorporate future technologies and methodologies. This forward-looking approach is essential in preventing technical debt and ensuring the longevity of the application.
Domain-Driven Design, first introduced by Eric Evans, emphasizes aligning software design with business needs. It provides a set of patterns and practices that help architects and developers create flexible, modular systems that can evolve with changing requirements. By centering the design process around the core domain and domain logic, DDD facilitates the creation of software that truly reflects the underlying business model.
Domain-Driven Design provides a framework for creating systems that are both scalable in terms of functionality and maintainable in terms of code organization. It offers strategies for managing complexity, facilitating communication between technical and non-technical stakeholders, and creating flexible systems that can evolve with changing business needs.
# Domain-Driven Design Quick Overview
Domain-Driven Design (DDD) is a software development approach that places the project's core focus on the domain and domain logic. Introduced by Eric Evans in his seminal book, DDD provides a set of principles and patterns for creating complex software systems that closely mirror the business domain they serve.
At the heart of DDD lies the concept of the **ubiquitous language**. This shared vocabulary, meticulously crafted by developers in collaboration with domain experts, forms the foundation of the model. It ensures that all stakeholders, from business analysts to programmers, communicate effectively using terms and concepts directly related to the domain. This alignment significantly reduces misunderstandings and helps create software that truly reflects business needs.
**Bounded contexts** represent another cornerstone of DDD. These are explicit boundaries within which a particular domain model applies. In large systems, different parts may have different domain models, each with its own ubiquitous language. Recognizing and defining these boundaries helps manage complexity and allows teams to work independently on different parts of the system.
**Aggregates** are a key tactical pattern in DDD. An aggregate is a cluster of domain objects treated as a single unit for data changes. The aggregate root, a single entity within the aggregate, ensures the consistency of changes within the aggregate and controls access to its members. This pattern is particularly useful in defining clear boundaries for transactions and maintaining data integrity.
**Domain events** are another crucial concept in DDD. These represent significant occurrences within the domain. By modeling important changes as events, DDD facilitates loose coupling between different parts of the system, enabling more flexible and scalable architectures.
In the context of microservices architecture, DDD proves exceptionally valuable. The bounded contexts in DDD often align well with individual microservices, providing a natural way to decompose a complex system into manageable, independently deployable services. This alignment helps in creating a modular system where each service has a clear responsibility and a well-defined interface.
The strategic patterns of DDD, such as **context mapping**, help in understanding and defining the relationships between different bounded contexts or microservices. This is crucial for managing the complexity that arises from distributed systems and ensuring that the overall system remains coherent.
By applying DDD principles, developers can create software that's not only aligned with business needs but also inherently more maintainable and scalable. The focus on the core domain ensures that development efforts are concentrated where they provide the most value. The clear boundaries and well-defined interfaces facilitate easier changes and extensions to the system over time.
In the following sections, we will explore how these DDD concepts can be applied to create a Twitter-like application using a two-microservice architecture. This practical example will demonstrate how DDD can guide the design of complex systems, resulting in a flexible and maintainable solution.
# Defining the Bounded Contexts
In applying Domain-Driven Design (DDD) to our Twitter-like application, the first step is to identify and define the bounded contexts. Bounded contexts are crucial in DDD as they delineate the boundaries within which a particular domain model applies. For our simplified Twitter-like platform, we'll focus on two primary bounded contexts, each corresponding to a microservice: `UserManagementService` and `MessagingService`.
## UserManagementService Bounded Context
The `UserManagementService` encompasses all aspects related to user accounts and profiles. This context is responsible for managing user identities, authentication, and user-specific information. Within this bounded context, the core concepts include:
- **User** - the central entity representing an individual account on the platform, which contains user-specific details such as display name, bio, and profile picture, authentication information like username and password, etc.
- **Role** - defines user role in the whole system, whether he's a messages producer or messages consumer only
The **ubiquitous language** within this context includes terms like "register", "login", "logout", "authentication" and "authorization". The `UserManagementService` operates independently, focusing solely on user-related operations without direct concern for messaging or content creation.
## MessagingService Bounded Context
The `MessagingService` handles all aspects of content creation, distribution, and consumption. This context is more complex as it manages both the creation of messages (tweets) and the subscription system. Key concepts in this bounded context include:
- **Message**: The core entity representing a piece of content (similar to a tweet).
- **Subscription**: Represents the follow relationship between users.
- **Feed**: A collection of messages from subscribed users.
- **Producer**: A user who creates content (messages).
- **Consumer**: A user who consumes content from their subscriptions.
The ubiquitous language here includes terms like "post message", "subscribe", "unsubscribe", "consume message". This context deals with the dynamic aspects of the platform, managing the flow of content between users.
## Context Interactions
While these bounded contexts are separate, they do interact. The `MessagingService` needs to reference users, but it does so without delving into the internal complexities of user management. Instead, it might use a simplified representation of a user, containing only the necessary information for messaging purposes.
Figure 1. Context Interactions between bounded contexts
For instance, when a user posts a message, the `MessagingService` doesn't need to know about the user's password or email address. It only needs a user identifier and perhaps a display name. This separation allows each context to evolve independently while maintaining necessary connections.
This separation is further reinforced by implementing the database-per-service pattern. In this approach, each microservice maintains its own dedicated database. The `UserManagementService` has a database that stores comprehensive user information, including sensitive data like passwords and email addresses. On the other hand, the `MessagingService` database focuses on message content, user subscriptions, and a minimal set of user data required for its operations.
To maintain necessary connections between services, the `MessagingService` keeps a minimal replica of user data required for its operations. This typically includes the user ID only. If `MessagingService` requires some data related to the user, it may request that information from `UserManagementService`. This may be useful for checking user roles for example or user name to display.
Technically speaking, this approach introduces some data redundancy, however organized correctly, such a redundancy may be reviewed as nothing much but as foreign keys used between different tables in RDBMS.
It allows each service to operate independently most of the time, enhancing overall system resilience. It also aligns well with the DDD principle of respecting bounded context boundaries, as each service has full control over its own data model and storage.
## Context Mapping
To manage the relationship between these bounded contexts, we employ context mapping. In this case, we might use a Customer-Supplier relationship, where the `UserManagementService` (supplier) provides necessary user data to the `MessagingService` (customer). This could be implemented through API calls or message queues, ensuring that each service has the information it needs without tightly coupling the two contexts.
Implementation of this context mapping involves several key aspects. First, the `UserManagementService` exposes a well-defined API that the `MessagingService` can use to retrieve essential user information. This API is designed to provide only the necessary data, such as user IDs and user roles, without exposing sensitive information. For example, when a new message is posted, the `MessagingService` might make an API call to the `UserManagementService` to verify the user's existence and his role.
Figure 2. Context Mapping between different bounded contexts
As part of the Customer-Supplier relationship, we define clear Service Level Agreements (SLAs) between the services. These SLAs specify the expected request and response structure, timeline for API calls, the frequency of event publications, and the handling of service outages.
Leveraging these patterns we will create a foundation for a modular, maintainable system. Each context has a clear responsibility and a well-defined interface, allowing for independent development and scaling. This separation also provides flexibility for future expansions, such as adding new features or integrating with external systems.
In the following sections, we'll delve deeper into each of these bounded contexts, exploring their domain models, aggregates, and services in detail.
# User Management Service
The `UserManagementService` forms a crucial part of our Messaging application, handling all aspects related to user accounts and roles. This service embodies its own bounded context, focusing solely on user-related operations. Let's delve into the key components of this service, structured according to Domain-Driven Design principles.
## Domain Model
At the core of the `UserManagementService` lies the User aggregate. In DDD, an aggregate is a cluster of domain objects treated as a single unit. The User aggregate encapsulates all user-related data and behavior.
The User aggregate root contains essential attributes such as `userId`, `username`, `email`, and `password`. It also includes methods for user authentication, user roles and user authorization. By centralizing these responsibilities within the User aggregate, we ensure that all user-related operations maintain data consistency and adhere to business rules.
Associated with the User aggregate are several value objects. These are immutable objects that describe characteristics of the User but have no conceptual identity. Examples include Email and Password. These value objects encapsulate validation logic, ensuring that email addresses are properly formatted in accordance with [RFC 2822](https://datatracker.ietf.org/doc/html/rfc2822#section-3.4) and passwords meet security requirements by its length and other criteria.
The Profile value object represents user-specific details like displayName, bio, and profilePictureUrl. By modelling Profile as a separate value object, we allow for easy expansion of profile-related features without cluttering the User aggregate.
## Repository
The `UserRepository` interface defines methods for persisting and retrieving User aggregates. This abstraction allows us to separate the domain model from the underlying data storage mechanism. The implementation of this repository interfaces with our chosen database system, in this case, MySQL.
The repository includes methods such as findById, findByUsername, and regular CRUD operations (CREATE-READ-UPDATE-DELETE). It also provides more specific query methods like findByEmail, which might be used during the user registration process to ensure email uniqueness.
Data model, which is also scoped to User aggregation only, might be represented as on the figure below.
Figure 3. User Management Data Model
## Domain Services (Domain Flows)
While most business logic resides within the User aggregate, some operations involve multiple aggregates or require external resources. For these, we use domain services which may exist as separate services or might be defined as modules inside a single service. As of now we will prefer to define those operations as separate reusable modules inside one service.
The `UserRegistrationModule` handles the process of user registration, which might involve checking for existing users, validating input, and triggering welcome emails. This module coordinates between the User aggregate, UserRepository, and potentially external services like email providers.
The `AuthModule` manages user login processes, including password verification and generation of authentication tokens, as well as handles requests to identify user roles. This module works closely with the User aggregate but keeps the authentication and authorization logic separate, allowing for easier updates to authentication and authorization mechanisms in the future.
`ApplicationGatewayModule` is responsible for communication with other external components and services. In some other sources it is also called a Controller, however we try to include here only logic, responsible for terminating incoming traffic, data serialization, input validation and forming responses to return them to the requesters. This module acts like a communication facade between different external services and internal modules, providing SLA for them, and at the same time keeping flexibility of internal modules.
The last module we may want to use is `DataAccessLayerModule`. We already defined the data model, now we need to determine the way to communicate with it. Using direct calls to the database from any point of the code is possible but may not be considered as a good idea because of many reasons, main ones are correlated to the high coupling and low cohesion between data model and application logic. Using this module we may decompose and abstract access our logic from accessing data. Instead of creating a specific SQL query to select specific user and access his permissions, we may simply create a method, called `getUserWithRoles`, and hide the implementation behind it. In that case we reach high consistency by calling the only one method, which we will be a single point to access data.
Figure 4. Block Diagram of Domain Modules
## Infrastructure Concerns
While not strictly part of the domain model, the `UserManagementService` also addresses several infrastructure concerns. These include implementing security measures like password hashing and token-based authentication, setting up database connections and ORM mappings, and configuring API endpoints.
The service also implements event publishing for significant domain events. When a user updates their profile, for instance, the service publishes a UserProfileUpdated event. Other services, like our further considering `NotificationService`, can subscribe to these events to maintain consistency across the system and deliver different state changes.
By structuring the `UserManagementService` according to DDD principles, we create a robust, maintainable service that clearly encapsulates all user-related functionality. This design allows for easy extension of user management features and provides a solid foundation for our Messaging application.
# MessagingService
The MessagingService forms the core of our Messaging application's content creation and distribution system. This service encompasses its own bounded context, managing messages (tweets) and subscriptions. Let's explore the key components of this service, structured according to Domain-Driven Design principles.
## Domain Model
The central aggregate in the `MessagingService` is the Message. This aggregate encapsulates the content created by users, along with metadata such as creation time and author information. The Message aggregate root contains attributes like `messageID`, `content`, `authorID` (which is a `userID`), and `createdAt`. It also includes methods for creating, editing (if allowed), and deleting messages.
Another crucial aggregate is the `Subscription`, representing the follow relationship between users. The Subscription aggregate contains a `producerID` and a `subscriberID`, which are no more than `userID` correlated to the appropriate data from the `UserManagementService`, along with subscription status and creation date. This aggregate is responsible for managing the relationships between content producers and consumers.
Value objects in this context might include `MessageContent`, which encapsulates the actual text or media content of a message and its author ID, to establish and determine the subscription status.
## Repository
The `MessagingService` might include several repositories in case we would like to split it into standalone services to manage messages and subscriptions. In this article we consider that functionality as closely related and manage it under the single umbrella of the `MesagingService` and within the single database for this service.
The MessageRepository handles persistence and retrieval of Message aggregates. It includes methods like regular CRUD, `findByMessageId`, `findByAuthorId`, and `findBySubscriberId`. We may also implement another method allowing users to filter messages by the time when they were created, which may be another convenient use case, and call this method as `findByCreatedAt`.
As it is seen, this database includes all those entities related to the messages and subscriptions. It's schema might be represented like on the figure below.
Figure 5. Messaging Service Data Model
## Domain Services (Domain Flows)
In this service we may define the same amount of modules as in the `UserManagementService` - 4, where 2 of them would be identical - `DataAccessLayerModule` and `ApplicationGatewayModule`, as these modules' responsibilities are generic and service agnostic. These 2 modules are intended provide border modules for data communication between `MessagingService` other ones. Eventually their goal is to convert and adjust incoming or outgoing data with its internal representation happening inside this Domain.
`MessagingModule` in this case this is the core module for the whole service as it manages messages creation, retrieval and editing (if supported). This modules accept data from different sources, including user input, like message's text, user data, obtained from `UserManagementService` by using User ID, provided by user and using internal logic performs the requested operation - create, retrieve or edit (if supported) message.
The `SubscriptionModule` handles the complex logic of managing user subscriptions, including creating new subscriptions, handling unsubscribes, and managing subscription statuses like muting or blocking.
Figure 6. Block Diagram of Domain Modules
## Infrastructure Concerns
The `MessagingService` implements several infrastructure-level features to support its operations, as concerns for this service should be different than for the `UserManagementService`. These include setting up message queues for handling high volumes of new messages, implementing caching mechanisms for frequently accessed subscriptions, and managing database connections for efficient data retrieval.
The service also may publish domain events such as `MessageCreated` and `SubscriptionChanged` to be consumed by other parts of the system or external services for features like notifications or analytics.
By structuring the MessagingService according to DDD principles, we create a robust and scalable system for handling the core functionality of our Messaging application. This design allows for efficient management of messages, subscriptions, while providing clear boundaries for future extensions and optimizations.
# Scalability and Performance Considerations
As our application grows in popularity, scalability and performance become critical concerns. This section explores strategies to ensure our microservices architecture can handle increasing loads while maintaining responsiveness and reliability. Generally speaking those techniques below are not critical for application functionality, however they become those when the system starts experiencing the high load.
## Horizontal Scaling
Both the `UserManagementService` and `MessagingService` are designed to be stateless, allowing for easy horizontal scaling. As user traffic increases, we can deploy multiple instances of each service behind a load balancer. This approach distributes the load across multiple servers, improving overall system capacity and resilience.
## Database Scaling
As the volume of data grows, database performance can become a bottleneck. To address this, we may implement several strategies for that.
For the `UserManagementService`, we establish a system of read replicas, as this service load assumes prevail retrieval operations over writing ones. This setup allows us to distribute read operations across multiple database instances, significantly reducing the load on the primary database. By directing read-heavy operations to these replicas, we ensure that the primary database can focus on write operations, thereby improving overall system performance and responsiveness.
The `MessagingService`, which deals with a substantially larger volume of data, requires a more robust scaling solution. Here, we may implement database sharding, a technique that involves partitioning data across multiple database instances based on user ID or message ID ranges. This approach not only distributes the data itself but also spreads the query load across multiple servers. As a result, we can handle a much larger number of concurrent operations and store a greater volume of data than would be possible with a single database instance.
In addition to these structural changes, we should place a strong emphasis on query optimization and indexing. Our database administrators and developers work in tandem to continuously monitor query performance, identifying frequently used query patterns and ensuring that appropriate indexes are in place to support them. This ongoing process of refinement helps maintain database efficiency even as the volume and complexity of data grow.
## Caching Strategies
Caching plays a pivotal role in performance optimization strategy, serving as a crucial layer between our services and the database. In the `UserManagementService`, we implement a sophisticated caching mechanism for user profile data. We may utilize any in-memory storage, like Redis, for high-performance in-memory data store, where we may cache frequently accessed user information. This approach significantly reduces the number of database queries required for common operations, such as retrieving user details for display or authentication purposes.
The `MessagingService` employs a more complex, multi-tiered caching strategy to handle the high-volume, real-time nature of social media feeds. We may use a combination of in-memory caching with Caffeine for the most recent and frequently accessed feed entries, providing near-instantaneous access to this hot data. For older or less frequently accessed feed data, we leverage Redis as a second-level cache. This tiered approach allows us to balance the need for ultra-fast access to recent content with the ability to efficiently store and retrieve a larger volume of historical data.
As our system scales horizontally, maintaining cache consistency across multiple service instances becomes critical. To address this, we configure Redis in cluster mode, ensuring that our caching layer is both distributed and consistent. This setup allows us to scale our caching infrastructure in tandem with our application services, maintaining performance as user numbers grow.
## Eventual Consistency and CAP Theorem Considerations
In designing our distributed system, we've had to grapple with the fundamental trade-offs described by the CAP theorem, which states that in the event of a network partition, a distributed system must choose between consistency and availability. Given the nature of our application, where the immediacy of information flow is a key feature, we've opted to prioritize availability and partition tolerance over strict consistency in many scenarios.
Figure 7. CAP Theorem Problem
This decision manifests in our embrace of eventual consistency. For instance, when a user updates their profile information in the `UserManagementService`, we acknowledge and apply this change immediately in that service. However, we accept that there may be a short delay before this update is reflected in the `MessagingService` or in cached data across the system. During this brief period, different parts of the system may have slightly different views of the user's data.
While this approach introduces the possibility of temporary inconsistencies, it allows our system to remain highly available and responsive, even in the face of network issues or high load. We mitigate the impact of these inconsistencies through careful system design, such as including timestamps with data updates to help resolve conflicts, and by setting appropriate user expectations about the speed of data propagation.
This eventual consistency model extends to other areas of our system as well, such as follower counts or message distribution. By relaxing the requirement for immediate, system-wide consistency, we can process high volumes of operations more efficiently, leading to a more scalable and responsive system overall. However, we're also careful to identify those areas of our application where strong consistency is necessary, such as in financial transactions or security-critical operations, and design those components accordingly.
# Conclusion
The journey of creating a Twitter-like application using Domain-Driven Design (DDD) and microservices architecture offers valuable insights into building complex, scalable systems. Through our exploration of the `UserManagementService` and `MessagingService`, we've demonstrated how DDD principles can guide the development of a robust, maintainable, and flexible application architecture.
By focusing on clearly defined bounded contexts, we've created services that are independently deployable and scalable, yet cohesive in their overall functionality. The use of aggregates, repositories, and domain services has allowed us to encapsulate complex business logic within each service, promoting code that is both more understandable and more closely aligned with the underlying business domain.
Our approach to data management, including the implementation of the database-per-service pattern and sophisticated caching strategies, showcases how modern distributed systems can handle large volumes of data while maintaining performance and responsiveness. The adoption of event-driven architecture for inter-service communication highlights the power of loose coupling in creating systems that are both resilient and adaptable to change.
Throughout this process, we've had to make important architectural decisions, balancing concerns such as data consistency, scalability, and system complexity. Our choice to embrace eventual consistency in certain areas of the application demonstrates the nuanced thinking required when designing distributed systems, taking into account the trade-offs described by the CAP theorem.
While our implementation focuses on core functionalities, omitting features like notifications and commenting, the architecture we've designed provides a solid foundation for future expansion. The principles and patterns we've applied can be extended to accommodate new features and services as the application grows.
It's important to note that the journey doesn't end with implementation. Continuous monitoring, performance optimization, and iterative improvement are crucial for maintaining and evolving such a system. As user behavior changes and new technologies emerge, our Twitter-like application must be ready to adapt and scale accordingly.
The combination of Domain-Driven Design and microservices architecture offers a powerful approach to building complex, scalable applications. By focusing on clear domain boundaries, embracing eventual consistency where appropriate, and leveraging modern technologies for data management and inter-service communication, we can create systems that are not only capable of handling current demands but are also well-positioned to evolve with future needs. | eugene-zimin |

1,898,519 | How to use Git | Master the Advanced Commands of Git | Git has become an indispensable tool for developers worldwide, streamlining the version control... | 27,838 | 2024-06-24T07:14:45 | https://dev.to/nnnirajn/how-to-use-git-master-the-advanced-commands-of-git-510h | git, github, programming, beginners | Git has become an indispensable tool for developers worldwide, streamlining the version control process and enhancing collaborative programming efforts. While numerous resources help beginners grasp the basics, this post is tailored for experienced web developers looking to elevate their Git game with advanced and techniques. Whether you manage complex codebases or need precise control over your repositories, mastering these commands can significantly increase your productivity and efficiency.
### Rewrite History with `git rebase`
Rebasing is one of Git's most powerful features, allowing you to modify your project's history. This process applies changes from one branch onto another, effectively recrafting your project's narrative.
#### When to use it:
- Cleaning up your commit history before merging a feature branch.
- Aligning your feature branch with the latest updates from the main branch, ensuring a smoother integration.
#### Steps and precautions:
- Always double-check the commits you want to rebase. Mistakes during rebasing can complicate your project’s history if not done correctly.
- It’s advisable to perform rebasing in a clean working directory to avoid loss of ongoing work.
---
### Maximize Insight with `git reflog`
The `git reflog` is a lifesaver in many situations, particularly when it comes to tracking every single step of your movements in your repo, even across all branches.
#### When to use it:
- Diagnosing what went wrong after a problematic rebase or merge.
- Recovering lost commits.
---
### Cherry-Picking with `git cherry-pick`
While merging and rebasing are suitable for applying many changes from one branch onto another, `git cherry-pick` can be used to select and apply just a single commit from one branch to another.
#### How to do it effectively:
- Identify the commit hash from the log `git log` of the branch you want to pick the commit from.
- Use `git cherry-pick <commit-hash>` to apply the commit to your current branch.
---
### Powerful Search with `git grep`
When you need to locate instances of specific text within your project's code base, `git grep` does a quick scan of your files in the Git repository, allowing you to find snippets without checking each file manually.
Ways to leverage `git grep`:
- Search for function calls or variable names across all your project’s files.
- Combine with other commands to refine searches or manipulate output.
---
### Advanced Merging Techniques
#### Strategic Merging with `git merge --no-ff`
Non-fast-forward merges `--no-ff` create a new commit object even if the merge could be performed with a fast-forward. This approach is useful in preserving information about the historical existence of a feature branch and grouping together changes.
#### Resolve Conflicts like a Pro with `git mergetool`
While simple conflicts can be resolved with standard text editors or IDEs, complex conflicts might require a specialized tool. `git mergetool` streamlines the conflict resolution process by providing a visual side-by-side comparison of conflicts.
---
### Advanced Management with `git remote`
Managing your remote repositories effectively ensures that your local repository communicates properly with the GitHub repository (or other online repos). `Git remote` manages tracked repositories:
```git
git remote add [name] [url]
git remote remove [name]
```
Adding a remote is straightforward, but remove wisely—ensuring it's not disrupting collaboration.
---
### Synchronizing with `git fetch` versus `git pull`
Both `git fetch` and `git pull` synchronize your local repository with a remote source, but understanding their differences amplifies their utility:
- `git fetch`: It downloads new data from your remote repository (branches, tags), but doesn't integrate any of this new data into your working files.
- `git pull`: It does what `git fetch` does but additionally merges the new data into your current working branch.
Using `git fetch` can be particularly useful when you want to see the changes before merging them into your branch, giving you a chance to review everything first.
---
### Stashing and Cleaning: Managing Your Working Directory
When juggling multiple features simultaneously, managing your work area cleanly is crucial. `Git stash` and `Git clean` are essential for maintaining a tidy workspace.
#### Saving Changes with `git stash`
`Git stash` temporarily shelves changes you've made to your working directory so you can work on something else, and then come back and re-apply them later on:
```git
git stash push -m "message about the stash"
git stash pop
```
This is perfect for when you need to quickly switch the context and do not want to commit half-done work.
---
### Keeping it Clean with `git clean`
To remove untracked files from your directory, `git clean` is your go-to command:
```git
git clean -n # Show what will be deleted
git clean -f # Force the removal of untracked files
```
Use this command with care! Once something is cleaned, it's gone for good.
---
### Debugging with Git
Git isn’t just for saving snapshots; it can also help you find bugs.
Time Travel with `git bisect`
Git bisect helps you find the commit that introduced a bug by performing a binary search between a known good and bad state:
```git
git bisect start
git bisect good [good-commit-hash]
git bisect bad [bad-commit-hash]
```
Git then checks out a commit halfway between the good and bad commits. You test it, mark it as good or bad, and Git continues narrowing down the problematic commit.
---
#### Conclusion: The Unseen Hero in Efficient Development
Though mastering Git's advanced commands requires time and practice, the payoff in terms of workflow efficiency and code quality is undeniable. By leveraging the full spectrum of Git’s capabilities, developers not only streamline their development processes but also enhance their capacity to handle complex projects with ease.
Remember, the true power of Git lies not just in managing your code, but also in strategically shaping the history and integrity of your project over time. So dive into these advanced commands, and watch your proficiency and productivity soar! | nnnirajn |

There is an app for just about anything, and the market for apps only seems to grow.
Why? Because the pandemic has ushered in an era of phone-heavy users, setting the perfect environment for businesses to scale by building apps.
In 2023 the number of smartphone users is forecasted to jump from 6.6 billion people to 9 million users worldwide, which will contribute to 24 billion app downloads. It is safe to say from these numbers that businesses hAPPen over phones. Depending on what your business offers, apps seem like a legit way to make your brand shine and be where your customers are (on their phones). This leads us to the all-important question:
So, how much does it actually cost to develop an app?
## Estimated Cost of Developing an App
Let’s get straight to the point. The estimated cost of developing an app can range anywhere from $40,00 to more than $300,000. However, the factors that influence these prices will differ according to different parameters, including: –
- The type of app
- The platform you would need for the app (iOS/ Android)
- The app developer (is it a freelancer/ UI UX agency)
Once you get the summary of these factors, you get the total price of what it takes to create the app.
## Types of Apps
For a better understanding of costs, we can bring down the classification of apps to three by terming them as simple, average, and complex apps. As you go from simple to complex, the features increase, the user interface develops, and ultimately the cost increases.
- **Simple Apps**
A simple app includes a primary interface that you get to see often. It also includes the [MVP functionality](https://www.peppersquare.com/blog/importance-of-minimum-viable-product/) and can only be used for a single platform. To develop an app of this nature, you will have to spend between 2 to 3 months, which includes weeks of planning, business analysis, design, pre-development, and more.
So, what’s the estimated cost? MVP functionality + single platform usage + basic interface + timeline could see the app development cost between $40,000 – $60,000.
- **Average Apps**
Average apps are the ones that are more complex than basic apps and will include specific features that guide higher costs. While they are still available on only a single platform, they differ from its predecessor thanks to the inclusion of customized UI.
On average, developers will spend between 3 to 6 months creating an app with medium complexity. So, including additional features, timeline, and more will give you estimated costs ranging between $120,000 – $200,000.
- **Complex Apps**
Creating a complex app or one with the best features can take time and effort. These apps typically have heavy graphics and functionality and can handle large data sets. They also include bespoke UI, which is tailor-made to suit clients’ requirements.
These apps are made for more than two platforms and require more than nine months of work to get it moving. Due to that, the estimated costs for developing complex apps could range between $200,00 to more than $300,000.
Hence, the app development cost for complex Apps is the highest.
## The Platform You Need for the App
Now that we know of apps and their estimated cost of development. Let’s be more specific with costs and come down to the platform. All three types of apps mentioned above are made for a single platform or more than two.
Meaning they are either hybrid apps or cross-platform apps. Hence, the classification comes down to the costs of developing an IOS and Android App.
## Estimated costs of developing an iOS App
Understanding the estimated costs of an iOS app boils down to the classifications we used above. A simple app that follows some of the [best iOS design practices](https://www.peppersquare.com/blog/top-9-ios-design-practices/) takes about 1 to 2 months to develop and will cost anywhere between $5,000 – $10,000.
Apps that are more advanced than those cost anywhere between $10,000 – $50,000 and take 2 to 6 months to develop. We can also have a complex or enterprise-grade app that could take more than 6 months to build and require an estimated budget of $50,000+.
There are several advantages to developing an iOS App, including the ease of finding developer resources. Apple also releases native APIs that are stable and perfect for use, making the process more time efficient.
In terms of tools, applications such as XCode for graphical interface and Swift for programming language are just two commonly used ones we get to see around. Moreover, developers can also use other tools such as Objective-C, Flawless iOS, and more which will have a say on the app development cost.
## Estimated costs of developing an Android App
Android has up to 2.8 billion active users covering a market share of 75%. There are about 130 million active users in the US and developing an app for them could cost anywhere between $20,000 – $300,000. And yes, developing an Android App is more expensive than an iOS App because the iPhone’s operating system is cheaper due to its unique coding language.
In terms of specifics, a simple Android app, which comes with MVP functionality and basic UI, could range between $20,000 – $50,000. For the next type of app, which includes more features, the estimated cost or the app building cost could range between $50,000 – $150,000.
And if we look into the most complex set of Android apps, which includes a customized UI, the cost of developing them will need an estimated budget of $150,000 – $300,000.
By customized and complex UI, we are talking about the latest tech advancements like AR/ AI integrations, increased security measures, and the process and programming language (Android Studio, Kotlin, and Java). Developing such complex Android apps will take at least 14 months of time and resources from the agency.
## App Development Cost Breakdown: Stages of Development
The different stages of developing an app could vary under several circumstances but remain the same in a general sense. They include getting a detailed business analysis, UI/UX plans, and more. Each stage takes a specific part of your budget, and we will estimate the percentage to be earmarked accordingly.
- **Business Analysis**
Business analysis is a part of the planning stages of developing an app. It includes the initial steps such as: –
- Gathering info and requirements
- Understanding the market
- Identifying various problems and challenges &
- Defining the project value
These steps are time-consuming but paramount in developing the right app. Once you gather all these inputs, you will have a direction to follow, and an app better aligned with your business by the end of the project.
If we were to account for budget allocation, you could easily set up 10-15% of your total budget for the business analysis stage. But, of course, these costs also depend upon whether you will need an in-house business analyst or a freelancer.
- **UI/UX design plan**
The next development phase includes building a user interface that is as flawless as one would imagine. That is where the importance of UI and UX design comes into being.
Since [design](https://www.peppersquare.com/blog/what-is-design-thinking-and-how-to-apply-it/) is considered an experience, this process stage will include steps to make that experience feel and look better.
So based on how you want the application to be, designers will go about making a prototype and take up a part of your budget. The process will involve,
- Viewing samples
- Understanding audience preferences
- Establishing a wireframe and finalizing the design.
Once these steps are ticked, you can see possibly another 10-15% of your budget be used for the process. Of course, this depends upon who is designing.
Today app development can be done by freelancers, agencies, or even enterprises. The best way to choose one is by doing a quick weigh-in on the pros and cons. For instance, though freelancers charge less, [UI UX design agencies](https://www.peppersquare.com/ui-ux-design/) have more resources.
- **Development phase **
Coding and other steps fall under the development phase of building an app. Therefore, this is another area of significance and takes up more of your budget when compared to the other steps.
One of the main reasons for the extra cost is the collaborative effort that goes into this phase. While the size of the app will affect that process, even a small application will require up to 2 members.
It could include back-end to front-end development; thus, nearly 50-60% of your budget could be spent on an application’s development stage.
- **Testing phase**
Now, this is where the fun begins! During this stage, a project manager ideally comes in to check how the app performs on an iPhone or an Android device.
The testing phase can last for weeks depending upon the size of the app and will only take up a little of your budget. In fact, project managers and designers would work with the amount left since this is the last phase of development.
Be careful though, because this is a crucial stage that could extend your budget because changes require more money. As soon as the application is made, you can move ahead and submit it for review and wait for the result.
## Additional Costs of App Development
Apart from the expenses that have been mentioned, you might have to deal with additional costs that relate to functionality, maintenance, and more. Spending in these areas is essential to maintain your app’s quality and stay up to date with the competition.
- **Functional & maintenance**
Functional costs are often ignored during the development phase despite being an integral part of it. They include fees for third-party integrations and keeping in mind the type of app you are developing; functional costs could be between $5,000 to $20,000 a year.
On the other hand, maintenance fees involve the money spent on fixing bugs, server fees, launching updates, and more. Therefore, regular updates will not only help your user base, but they can also help fix bugs that occur from time to time.
The cost of fixing bugs and providing updates is dependent on several factors. For example, if the problem involved a bug that aligns with coding, you could see a bill of up to $2,000. While that is a mere estimation, the actual price could still go up depending on the size of your app.
Coming to server fees, it could be between $70 to $320 per month. Based on your app data and how it is structured, be it text-based or audio and video based, you will have to deal with these costs, which is a critical expense.
- **Security**
For users to trust your app, you require the best security plan. And security needs to be inclusive of every component. Based on the components that you have in your app, like program execution resources and more, you need to conduct checks, hold access controls for the database, analyze network access controls, and more.
However, what’s more, important is firewall configuration and how it changes from the development stage to the final edit. While firewall access can be open for every component in the development stage, during the final edit, it needs to be restricted.
And in doing these steps, you are going to incur some expenses which count as additional costs.
## Overview of App Development Cost of Famous Apps
- **Tik Tok:**
World famous entertainment app, Tik Tok was the creation of Zhang Yiming. Currently valued at $66 Billion, the app is known to have needed anywhere between $40,000 to $45,000 for development.
With the inclusion of advanced features and app development cost for multiple platforms, Tik Tok could also cost up to $100,000. As a famous entertainment app, the valuation of TIK Tok can only increase further along with development costs.
- **Instagram:**
With over 2.35 billion monthly active users, Instagram is one of the most famous applications in the world. The social media app, which was launched in 2010, is known to have increased in valuation since its launch.
In terms of the cost to build an app like Instagram, you will be spending anywhere between $30,000 to $500,000. But with additional features and various other factors, the app development cost can only increase.
- **Facebook:**
Although Facebook wasn’t the first social media platform, it was the first to ever have a live feed. And that brought in tons of followers, taking Facebook to a whole new level. Today, this social media company known as Meta owns over 91 other companies including the likes of Whatsapp and Instagram.
When it comes to the cost of development or app cost, you will have to spend between $30,000 to $250,000. But be prepared for additional costs.
- **WhatsApp:**
Putting an end to the costly demands of SMS services, we got a messaging platform called Whatsapp in 2009. It changed the way we communicated with people and soon everyone had an app called whatsapp in their smartphones.
To develop the same, Brian Acton and Jan Koum could have spent between $35,000 to $250,000, although additional expenses relating to UI/UX designing, hourly rates of development and more could have taken the price further.
## Whom should you hire for app development?
In the current scenario, there are several options that one can consider when it comes to app development. From agencies to freelancers, the list is endless, and the budget will vary accordingly.
- **A local agency**
Design agencies are all around and come with a skilled workforce who can develop an app for you. Considering the size of their company, you can also expect to avail SEO services along with app development.
While they cost the most among the lot, they could also provide the best service as design agencies are known to have all the resources in one place. You can also maintain a good line of communication and be specific about your requirements.
In terms of costs, some factors include the size of the agency, quality of work, and additional costs such as maintenance, copywriting, editing, and more.
- **Freelancers**
You can always hire freelancers to develop your app, and their costs will be based on a contract or hourly. Professional freelancers are always available, and by contacting them, you can discuss your budget and the type of app you want to develop.
While freelancing is easy and cost-effective, the process might be time-consuming depending on the number of people working on the project. Also, you may need a better line of communication, although that depends upon who is coming to do the project.
- **Outsourcing**
Apps that require more stages of development or ones that are more complex are usually outsourced. While outsourcing requires more budget, you can effectively look for developers who can provide their services.
It is a viable option, especially if you want to build an MVP, and can even be considered cost-effective under certain circumstances. First, however, you need to know their line of work and understand how their services will benefit you.
Secondly, after thoroughly understanding the market, you can opt for a single agency or even hire multiple agencies to complete the project. Countries like India, China, Ukraine, Poland, and more are known to be the best in outsourcing app development.
**Takeaway**
Like every other process, developing an app moves through different stages of development and requires the right budget to get things done. A shortage of resources or finance will impact the output and take things in another direction.
Be it a simple MVP app or a complex application, you require the right resources to get started and move ahead to complete the project. So, consider the right moves and get your app loading.
**FAQs**
**How much time does it take to develop an app in 2023?**
The average time to develop an app could be between 7 to 12 months. This time frame is spread between discovery, design, development, and the stages of testing, which is crucial to deciding an app’s making cost.
**How much does app maintenance cost?**
On average, maintaining an app could cost you between $250 to $500 a month. This amount is spent to keep the app updated and falls under the bracket of additional app development costs.
**How much does it cost to create a mobile app for small businesses?**
The cost of mobile apps is more dependent on the type of apps, meaning small businesses can target small apps or less complex ones. These apps come with a simple interface, and MVP functionality and can take about 2 to 3 months to develop.
The cost of building an app in this context could be between $40,000 to $60,000.
**What is the cost of developing an app for Android?**
The estimated cost of developing an Android app could range between $20,000 to $300,000. This amount is spent on UI/UX designing, development, testing, and more, making it all a part of the app building cost. | pepper_square |
1,898,510 | Voice AI: How to build a voice AI assistant? | Voice is an interesting platform; can you imagine building a voice service that can pick up the phone... | 0 | 2024-06-24T07:03:30 | https://dev.to/kwnaidoo/voice-ai-how-to-build-a-voice-ai-assistant-5bem | ai, machinelearning, python, productivity | Voice is an interesting platform; can you imagine building a voice service that can pick up the phone and have a conversation with a human in real-time?
This may have been far-fetched a few years ago, but now it's totally possible and relatively simple to achieve.
## How to achieve this?
To build a Voice AI service, you need a few components:
1. **SIP:** A protocol that allows a regular phone to make and receive calls over the internet. Usually with SIP, you need a softphone like Linphone and a SIP account (a username, password, and sip domain). For VoiceAI, you'll need to build a headless client that can run as a daemon. An alternative is just to use Twilio media streams.
2. **Audio transcription:** Service such as OpenAI Whisper. This will be responsible for translating audio into text.
3. **Text-To-Speech**: A service such as OpenAI TTS.
To keep this article simple, we'll just use Twilio's media stream service.
## What are Twilio media streams?
Twilio is the most popular digital telecoms service provider around, they offer a wide variety of voice, WhatsApp, and SMS services which makes our lives as developers much easier. Instead of building a headless SIP phone from scratch, we can just use media streams.
> I am not affiliated with Twilio in any way, but I do use quite a bit of their APIs in my own projects.
**Media streams** provide a WebSocket connection enabling you to receive or make calls programmatically.
When a call comes in, Twilio will connect to your WebSocket and stream the audio, which you can then process using AI and send back a piece of audio directly to the caller.
## Setting up a WebSocket
Flask is a bit dated! I prefer FastAPI, however, to make it easier for you since Twilio docs generally use Flask - we'll stick with Flask.

1,898,508 | Exploring Web Development: HTMX | What is HTMX The last 2 weeks I have been exploring HTMX, a light-weight, front-end... | 0 | 2024-06-24T07:02:50 | https://dev.to/alexphebert2000/exploring-web-development-htmx-4no1 | ## What is HTMX
The last 2 weeks I have been exploring HTMX, a light-weight, front-end library that looks to bring the needs of a modern web app back to just HTML. While HTMX is written in JavaScript, using HTMX doesn't require you to write a line of JavaScript to create a fully fleshed, interactive front end. HTMX uses custom HTML attributes to allow any HTML element to perform AJAX requests, manipulate the DOM, trigger CSS transitions and animations, and handle WebSocket events. The key difference between a site running HTMX and a site running another front-end library React is ironically the server. HTMX relies on _HTML_ responses from the server rather than JSON or any other data. HTMX allows you to take the HTML response from the server and insert or replace the element anywhere in the DOM. This means the dynamic parts of the view need to be generated by your server rather than the client.
## The 4 "Whys" of HTMX
HTMX's inception was based on 4 questions that address problems with bare HTML as basis for modern web applications. HTMX provides solutions to these 4 questions. But first lets look at the HTML `<a>` element. You use this element to get some HTML from a server and render it, replacing the DOM with the new HTML. An `<a>` tag in bare HTML would look something like this:
```HTML
<a href="/blog">Link to Blog</a>
```
### HTTP Requests
#### _Why should `<a>` and `<form>` tags be the only tags to make HTTP requests?_
Modern web apps use AJAX requests to send and receive information from the different parts of the app. So why should `<a>` and `<form>` tags be the only elements that can perform these important actions. HTMX allows all elements to perform AJAX request using custom hx attributes. So we can take our `<a>` tag from earlier and turn it into a button that does the same thing.
```HTML
<button hx-get="/blogs">Click to go to Blog!</button>
```
### Triggers
#### _Why should only_ click _and_ submit _events trigger AJAX requests_?
Since only `<a>` and `<form>` can perform AJAX request in bare HTML, only _click_ and _submit_ events can trigger them. With HTMX events like _mouse over_, _key presses_, _change_ can trigger AJAX requests. HTMX also has special events that can trigger element requests like _load_, _revealed_, and polling with `hx-trigger`. HTMX triggers can also include modifiers that can delay, throttle, and prevent multiple triggers. We can get the HTML from "/blogs" when hovering over a div instead of clicking a button.
```HTML
<div
hx-get="/blog"
hx-trigger="mouseover"
>
Hover to see the blog!
</div>
```
### Verbs
#### _Why should only _GET_ and _POST_ methods be available?
Generally in bare HTML, `<a>` tags perform GET requests and `<form>` tags perform POST requests. With HTMX you can use any element to perform any request type.
| Attribute | Verb |
|-----------|--------|
| `hx-post` | POST |
| `hx-patch` | PATCH |
| `hx-get` | GET |
| `hx-delete` | DELETE |
| `hx-put` | PUT |
### Replacement
#### _Why should you only be able to replace the entire screen?_
When you receive HTML from a server when working with bare HTML, the response data replaces the entire DOM. HTMX allows you to insert or replace elements anywhere in the DOM. This allows server responses to to respond with a single HTML snippet rather than an entire page, HTMX can dynamically add, subtract or replace elements as needed to form the page from the snippets provided by the server. Elements can be targeted with CSS selectors and extended syntax that allow you to define the target easily. Keywords like `closest` and `next` allow you to avoid coming up with endless class names by targeting an element by referencing its relative position. The way to swap or insert can be defined with the `hx-swap` attribute. With this we can render the a list of blog posts in a div dynamically, adding new posts to the top of a container div with each button press.
```HTML
<div class="blogs-container"><!--- Blogs Go Here ---></div>
<button
hx-get="/blog"
hx-target=".blogs-container"
hx-swap="afterbegin"
>
GET BLOG!
</button>
```
## Final thoughts
I find HTMX to be a very appealing technology. It is a very light, independent library. I think relying on the back-end to handle data and front-end to simply render and ask for changes falls more in line with the spirit of REST and simplifying the front-end back to HTML and CSS is something I find quite novel in this era of web development. There is increased risk of XSS attacks if HTMX is not implemented and sanitized correctly, and it feels a bit sacrilegious to use JavaScript as the server with Node and remove the JavaScript from the front end with HTMX. Overall I am planning and excited to use HTMX in the future. If you are also interested in trying HTMX, see their [great docs](https://htmx.org/docs/) to get started. Good luck and happy coding! | alexphebert2000 | |

With various API protocols available, choosing the right one can be challenging. This article aims to focus on differences among **REST, GraphQL, RPC, gRPC**, providing a comparative analysis to help developers and businesses make informed decisions.
In the next article of this series, i have discussed example for each of them : [Examples of REST, GraphQL, RPC, gRPC](https://dev.to/rahulvijayvergiya/examples-of-rest-graphql-rpc-grpc-48bo)
## REST (Representational State Transfer)
**Overview:** REST is an architectural style for designing networked applications. It relies on stateless, client-server communication, and uses standard HTTP methods such as GET, POST, PUT, DELETE.
**Key Features:**
- **Statelessness:** Each request from a client contains all the information needed to understand and process the request.
- **Uniform Interface:** Standard HTTP methods are used for CRUD operations.
- **Scalability:** Designed for scalable, distributed systems.
- **Flexibility:** Can return data in multiple formats (e.g., JSON, XML).
**Challenges:**
- Can be over-fetching or under-fetching data.
- Lack of built-in support for real-time data.
---
## GraphQL
**Overview:** Developed by Facebook, GraphQL is a query language for APIs and a runtime for executing those queries by allowing clients to request exactly the data they need.
**Key Features:**
- Precise Data Fetching: Clients specify the structure of the response, minimising over-fetching and under-fetching.
- Single Endpoint: All requests are sent to a single endpoint.
- Introspection: Self-documenting nature makes it easy to understand the API schema.
- Real-time Data: Supports subscriptions for real-time updates.
**Challenges:**
- Can be complex to implement and optimize.
- Overhead on the server side due to the need to parse and execute queries.
---
## RPC (Remote Procedure Call)
Overview: RPC is a protocol that one program can use to request a service from a program located on another computer in a network without having to understand network details.
**Key Features:**
- Simplicity: Makes it appear as though a local procedure call is happening.
- Efficiency: Designed for high-performance computing environments.
- Language Agnostic: Can be implemented in various programming languages.
**Challenges:**
- Tight coupling between client and server.
- Limited flexibility and scalability compared to REST and GraphQL.
---
## gRPC (Google Remote Procedure Call)
**Overview:** gRPC is an open-source RPC framework developed by Google. It uses HTTP/2 for transport, Protocol Buffers (protobufs) as the interface description language, and provides features such as authentication, load balancing, and more.
**Key Features:**
- High Performance: Uses HTTP/2 for multiplexed streams and efficient binary serialisation with Protocol Buffers.
- Strong Typing: Enforces API contracts via Protocol Buffers.
- Bi-directional Streaming: Supports real-time communication through streaming.
- Multi-language Support: Generates client and server code in multiple languages.
**Challenges:**
- Steeper learning curve.
- More complex setup and maintenance.
## Feature Comparison Table: REST, GraphQL, RPC, gRPC
| Feature | REST | GraphQL | RPC | gRPC |

## What I Built
I have developed a platform where people can donate money to social campaigns. Additionally, I created an AI-powered WhatsApp bot using Twilio's API that allows users to receive grants by sharing videos of their contributions related to active social campaigns. The AI classifies these videos and rewards users by adding money to their wallets based on their contributions. This system supports individuals, animals, and the environment in critical times by reducing dependency on NGOs and governments. People can sponsor campaigns, and the AI bot will classify and distribute grants from those sponsorships to individuals who actively contribute to the campaign.
## Demo
Step 1 : User signs up on platform , connect his wallet and can fund or sponsor social campaigns.
Step 2 : User gets message on whatsapp with all the active campaigns and rewards for contrubting towards it . If the user has contributed has contributed to any campaign then he/ she can share a video of it to our whatsapp bot and the AI model would classify that if the user has contributed or not and based on that he would earn rewards for contributing towards social mission.
Demo :
{% embed https://youtu.be/8q8Mxp7g_pM %}
Github Code : [code](https://github.com/Chirag-Agrawal/twilio)
## Twilio and AI
Twilio Capabilities:
WhatsApp API: Integrated Twilio's WhatsApp API to enable seamless interaction between users and the AI bot for chats and media sharing .
AI Integration:
Video Classification: Implemented an AI model of gemini to classify user-submitted videos. The model analyzes videos to determine if they showcase meaningful social work aligned with active donation campaigns.
Automated Responses: Leveraged AI-generated responses to notify users of their video submission status and reward eligibility.
Future Vision :
1. Add more ai capabilities features to recognize and store docs of users receiving rewards for an exceeded limit . along with their submission pattern and show videos uploaded by users on platform to motivate others.
2. Integrate more Twilio api's like current location api , calls api to support more social campaigns especially for geographical locations hit by natural calamities or war zones, etc !
## Additional Prize Categories
Impactful Innovators: The project drives positive social impact by encouraging and rewarding community involvement in social work activities tied to donation campaigns and environmental effects. This projects supports more social causes and campaigns by reducing the dependency from NGO's and governments and empowers more individuals to support social campaigns, specially in unpredicted times like disasters ,wars or global crisis.

Good morning everyone and happy MonDEV! ☕
I hope that with this heat you are running light processes on your PCs, to avoid melting neither you nor your processors! 😂
Today I want to talk about a tool that makes lightness its cornerstone.
It's called [Valibot](https://valibot.dev/).
Valibot is an npm package for data validation.
It works independently with JS and TypeScript and allows a wide variety of validations. In practical terms, as for the methods, it's essentially 1 to 1 with the most commonly used package for the same task, namely [Zod](https://zod.dev/).
Talking about the main strength of this library, we can say that the main strength leveraged by this tool is fundamentally its lightness during the build phase. In fact, each validation is contained as a separate method within the main module, allowing us to import only the necessary validations and not the entire package as a whole into our project.
The origin of this library is very interesting, deriving from the author's thesis ( [available online](https://valibot.dev/thesis.pdf) ) which is about writing a modular library focusing on size and performance. Inside it, you can find a comparison with various tools that do the same thing and the reasoning that led Fabien Hiller, the developer of the project, to design his library in this way.
I think this approach can be very interesting because it allows for a deeper comparison with the genesis of a project, something that is often missing!
What do you think? Have you ever tried Valibot or are you thinking of reading the thesis that inspired it?
Let me know as always, because I am very curious! Have a great week and as always

1,898,499 | Integrating TinyML, GenAI, and Twilio API for Smart Solutions | This is a submission for the Twilio Challenge What I Built The goal of this project is to... | 0 | 2024-06-24T06:58:40 | https://dev.to/engineeredsoul/integrating-tinyml-genai-and-twilio-api-for-smart-solutions-4o01 | devchallenge, twiliochallenge, ai, twilio | *This is a submission for the [Twilio Challenge](https://dev.to/challenges/twilio)*
## What I Built
<!-- Share an overview about your project. -->
The goal of this project is to demonstrate the integration of Generative AI (GenAI) in embedded systems and to highlight the ease of accessing AI capabilities via Twilio's API.
I have integrated a continuous motion recognition system with generative AI that recognizes and tracks motion and uses Twilio's WhatsApp API to alert users and respond to their questions.
## How I Built
### Continuous Motion Recognition
Unlike rule-based programming, which struggles with the variability in human gestures, machine learning easily adapts to these differences.
The Continuous Motion Recognition project using [Edge Impulse](https://edgeimpulse.com/) leverages advanced ML techniques to enable real-time, on-device motion detection and classification. Edge Impulse, a leading platform for embedded machine learning, provides a comprehensive toolset for collecting data, designing, and deploying custom models directly to edge devices. This project typically involves gathering motion data from sensors such as accelerometers and gyroscopes, then using Edge Impulse to preprocess the data, train models, and optimize them for efficient, low-power inference on microcontrollers or other edge hardware.
You can follow the [Continuous motion recognition | Edge Impulse Documentation](https://docs.edgeimpulse.com/docs/tutorials/end-to-end-tutorials/continuous-motion-recognition) tutorial to get started with it. You can view and clone the project [here](https://studio.edgeimpulse.com/public/432186/live).
So, if you have gone through it successfully and deployed it with your firmware and when you run the inference, you will be able to see the real-time recognition of the motion.
### Storing the result
For this project, I used [Xata](https://xata.io/) as the database. I have filtered out the result with the maximum value from each prediction and stored it in the `predictions` table. If you are new to Xata, checkout [Getting started with Xata](https://aadarshkannan.vercel.app/posts/Getting-Started-With-Xata/) guide.
### Twilio and AI
<!-- Tell us how you leveraged Twilio’s capabilities with AI -->
#### Twilio's WhatsApp Messaging Service
Twilio provides access to the WhatsApp Business Platform through its APIs. This allows developers to integrate WhatsApp messaging into their applications. We can leverage familiar Twilio APIs like Programmable Messaging to send and receive messages with text, media, and even certain pre-built templates.
I have used Python-Flask for creating the server and responding to the incoming messages. You can check out the Twilio documentation on [Receive and Reply to Incoming Messages - Python](https://www.twilio.com/docs/messaging/tutorials/how-to-receive-and-reply/python) for a better understanding of how it needs to be implemented.
#### Delivering the message
By using the Twilio sandbox, we are able to send and receive messages, create automated responses, and integrate interactive messaging features within a controlled setting.
When someone replies to one of our messages, we will receive a webhook request from Twilio. So, we need to configure the webhooks by connecting to our server/app. I ran my server using [Replit](https://replit.com/). Search for the Flask template and integrate the Twilio API.
{% embed https://replit.com/@dotaadarsh/EdgeAIxTwilioxXata?v=1 %}
#### Google Gemini AI
I used Google's 1.5 Flash Model to generate responses based on predicted data. When a user replies on WhatsApp, the endpoint URL is configured to our server on Replit, which listens for these messages. We then retrieve all records from the database and pass them, along with the user's message, to the Gemini AI for generating a response. The generated response is then sent back to the user on WhatsApp.

What is Stem Cell Therapy?
**Stem cell therapy[](uhttps://irmsc.com/our-services/stem-cell-therapy/rl)**, often hailed as a breakthrough in modern medicine, harnesses the power of stem cells to treat or prevent various health conditions. These remarkable cells have the unique ability to develop into different types of cells within the body, providing an unparalleled opportunity for regenerative medicine.
Types of Stem Cells Used in Therapy
Stem cells come in several forms, each with distinct characteristics and potentials for medical use:
Embryonic Stem Cells (ESCs): Derived from early-stage embryos, ESCs can differentiate into any cell type, making them incredibly versatile for research and therapeutic purposes.
Adult Stem Cells: Found in various tissues like bone marrow and fat, adult stem cells are multipotent, meaning they can develop into a limited range of cell types. They are commonly used in treatments for blood disorders and certain cancers.
Induced Pluripotent Stem Cells (iPSCs): Created by reprogramming adult cells to an embryonic-like state, iPSCs offer a flexible and ethical alternative to ESCs. These cells are valuable for personalized medicine and drug development.
Applications of Stem Cell Therapy
Stem cell therapy holds promise across a spectrum of medical fields:
Orthopedics: Stem cells can aid in repairing cartilage, bones, and tendons, offering relief for patients with injuries or degenerative diseases like osteoarthritis.
Cardiology: Researchers are exploring how stem cells can regenerate damaged heart tissue after a heart attack, potentially reducing the risk of heart failure.
Neurology: Conditions such as Parkinson's disease, spinal cord injuries, and stroke may benefit from stem cell therapy, which aims to replace or repair damaged nerve cells.
Oncology: Stem cell transplants are crucial in treating certain cancers, especially blood cancers like leukemia and lymphoma, by replenishing healthy blood cells after chemotherapy.
Benefits of Stem Cell Therapy
The advantages of stem cell therapy are compelling:
Regenerative Potential: Stem cells can promote the healing and regeneration of damaged tissues, offering hope for conditions previously deemed untreatable.
Reduced Dependency on Donor Organs: By regenerating tissues and organs, stem cell therapy could decrease the reliance on organ transplants, reducing waiting times and rejection risks.
Personalized Medicine: Stem cells can be tailored to an individual's specific genetic makeup, enhancing the effectiveness and reducing the side effects of treatments.
Challenges and Ethical Considerations
Despite its promise, stem cell therapy faces several challenges:
Ethical Concerns: The use of embryonic stem cells raises significant ethical questions, particularly regarding the destruction of embryos. iPSCs and adult stem cells present more acceptable alternatives for many.
Technical and Safety Issues: Ensuring the safe and controlled use of stem cells, including avoiding risks like tumor formation, is a critical aspect of ongoing research.
Regulatory Hurdles: Navigating the complex landscape of medical regulations can slow the development and approval of new stem cell therapies.
The Future of Stem Cell Therapy
The future of stem cell therapy is bright, with continuous advancements on the horizon. As research progresses, the potential applications will expand, offering innovative solutions to a growing array of medical challenges. Collaboration between scientists, clinicians, and ethicists will be crucial in navigating this exciting field, ensuring that the benefits of stem cell therapy are realized safely and ethically.
In conclusion, stem cell therapy represents a transformative frontier in medicine, promising to reshape how we treat and understand various diseases and injuries. The journey of harnessing these powerful cells is just beginning, with endless possibilities waiting to unfold.

1,897,415 | 🕸 Networking is easy, fun, and probably not what you think it is. | Networking is extremely important for your career. They say the most valuable thing about going to... | 0 | 2024-06-24T06:54:49 | https://suchdevblog.com/opinions/NetworkingIsNotWhatYouThink.html | career, beginners, learning, community | Networking is *extremely important* for your career.
They say the most valuable thing about going to Harvard is not the education you'll receive or the skills you'll learn, but the connections you'll make. And they're right.
However, many people will say networking is hard, boring, impossible for some, especially neurodivergent folks. So just for context, I'll clarify that this article is written by an introverted senior software engineer with autism. Turns out, I am a natural networker anyway! And maybe so are you.
---
When you think of networking, you probably have some kind of tech meet-up in mind. Maybe there is free coffee, pizza, and *petit-fours*, which you eat while talking to people from your industry who you can add on LinkedIn after.
While this is definitely an example of networking, this is also what people think networking *is*. In truth, this is only a very niche kind of networking.
Thinking you need to practice this specific ritual to gain the benefits of networking is like thinking you absolutely need to go to speed-dating events to get married. It might work out for you, but that's not what dating or marriage is as a whole, and it's not even how most people find their significant others.
The reality is, networking can be something you intentionally *do*, but more often than not it's something that *just happens*, and you benefit from it if you have the right skills and the right attitude.
## How I got my dream career
Here are two stories that led to me working at my dream job today.
### I Was Bored At A School Party
I never graduated in CS. I graduated in Food science. My first job was making energy drinks.
I met my friend J. during an engineering school party 15-20 years ago. We had similar interests and vibed together. He was studying computer science in that same school and later went on to become one of the top-leading experts in Ruby on Rails.
A decade after said party, as I was complaining about my lack of job prospects and interest for my current career, he asked me, "Have you considered coding?"
### I Talked To Some Teenagers Under A Tree
More than two decades ago, I was studying in a somewhat fancy high school, mostly middle-class / high-middle class students.
There was a tree in the courtyard where myself and a group of other teenagers would hang out. Eventually, we talked. We became friends.
One of them went into computer science and made a new group of friends. At some point, two people in this group started a new project for a client. They needed programmers. They hired me as an intern.
## This is what networking is.
I went to a bunch of professional meet-ups, coding-related events, and tech talks. No opportunity ever came out from any of those.
I don't regret going because I had no expectations outside of having a little fun and indulging in free pizza. Again, this is like dating, you have very little chance of finding your life partner on a random date so you have to learn to enjoy the process.
Instead, opportunities arise organically from just living life.
## Real networking advice
So how does one become "good at networking"?
### Be curious
Curiosity is an incredibly powerful human drive for growth.
Be curious about other people. People are fascinating, each individual is a universe of its own. There is so much to discover in a person, and so many persons to discover.
When you take an interest in other people, you're making their abilities, knowledge, and skills yours, and [there is tremendous power in alternative views](https://dev.to/samuelfaure/why-diversity-is-important-no-really-actually-for-real-1b7l).
So what you're doing is spreading a net, extending far and wide - this is networking.
*Geopolitical footnote: You will notice that, historically, the more insular a country is, the more stunted their economic growth is. This speaks volumes to the importance of human connections.*
### Be open to opportunities
To continue the fishing metaphor, once your net is spread, eventually you catch some fish. Now it's just a matter of picking up the fish.
Sounds easy enough, but some fishes are not easy to pick. Sometimes opportunities carry risk. Each situation is unique so it's hard to generalize here, but it is my opinion people generally have much to gain by being at least a little bit more bold.
### Be kind
Humans are fundamentally social creatures. We are designed for cooperation. Well, turns out humans prefer to cooperate with people who are well-suited for cooperation, and a big part of it is treating others with kindness.
If you are a pleasure to interact with, people will want to interact with you. This is true for friendship, companionship, but also work.
*Sidenote, I am not advocating that you should be kind for personal gain, since I believe in the value of kindness for its own sake. However, if this convinces an unkind person to start being kind for their personal gain, I will consider that a complete win*.
### Be generous
I am infinitely grateful to the people that helped me be where I am today.
But what goes around comes around. As people helped me, I helped others. I was turned into a software engineer, I turned others into software engineers.
At least one of them became a cybersecurity expert. He deepens my understanding of the topic on a regular basis. Helping him made me better at my job.
I spend some of my free time volunteering to mentor people who try to make software engineering their career. I mostly do this out of love for human connection & helping people. I have nothing else to gain from this & never gained anything from it, but who knows! I have the feeling some day this net might bring in some fish.
Life is not a zero-sum game. When you help someone you are often helping yourself.
## Privilege-checkpoint ✋🛑
I want to highlight something important.
You might have noticed that, even though I did not go to Harvard, I went to a somewhat fancy high school, and then to a somewhat fancy engineering school. Those are the places where my connections eventually led to getting into tech & finding my dream job.
This was only possible because I come from middle-class. Had I come from a more modest background, those opportunities would not have been there for me to seize in the first place.
I point this out because while it is easy to remember the hard work we achieved to get to where we are today, it is also easy to not notice the subtle ways invisible privileges made all of this possible for us. Let's all be mindful of this.
## What if I'm an introvert?
A final word for introverts. Introversion is characterized by "being drained by social interactions". I am absolutely such a person, social interactions drain my energy quite fast.
But then, so does physical exercise. Yet, almost anyone can eventually run a marathon with enough training.
Both social interactions and running can be torture when you start. Still, those are fundamental abilities of humans. We are literally designed for it. We can learn it, and with enough training we end up loving it.
Running is good for you, so is interacting with other humans, so go out there and train that muscle. It might always be tiring, but you'll enjoy it eventually.
## Conclusion
Networking is not (only, nor mostly) eating pizza at tech events.
It's first and foremost about connecting with others humans.
It's not really something you do for your job, it's something you do because that's what humans do and enjoy doing.
So go out there and connect, and keep an eye out for opportunities to cooperate. Who knows, you might end up cooperating!

1,898,496 | How Authentication works (Part2) | Continuing from part 1, I have done some refactoring. Instead of decoding the token in the frontend... | 0 | 2024-06-24T06:54:04 | https://dev.to/mannawar/how-authentication-works-part2-3ibb | react, redux, aspnet, sqlserver | Continuing from part 1, I have done some refactoring. Instead of decoding the token in the frontend and then sending all the information (such as email, displayName, and userName) over HTTPS, I now prefer to send just the token. In the backend, this token is decoded and mapped to the required parameters. This approach ensures that all security aspects are handled by our backend. HTTPS provides secure transit mechanisms, so I did not consider encrypting the token. Finally, I removed the jwt-decode package from the React app.
If you are following from my previous post, the handleGoogleSuccess method would look something like this now in front end React.
```
const handleGoogleSuccess = (response: any) => {
const tokenId = response.credential;
dispatch(signInWithGoogle({ tokenId}))
.unwrap()
.then(() => {
toast.success('Registration successful!');
navigate('/Book');
})
.catch((error: any) => {
toast.error('Some error occurred - Please try again later');
console.error('Google sign in failed:', error);
});
console.log('Google sign in successful:', response);
}
```
And the controller action method would look like this.
```
[AllowAnonymous]
[HttpPost("registergoogle")]
public async Task<ActionResult<UserDto>> RegisterGoogle(GoogleRegisterDto googleRegisterDto)
{
GoogleJsonWebSignature.Payload payload;
try
{
payload = await GoogleJsonWebSignature.ValidateAsync(googleRegisterDto.GoogleTokenId);
}
catch (Exception ex)
{
return Unauthorized(new { Error = "Invalid google token" });
}
var email = payload.Email;
var displayName = payload.Name;
var userName = payload.Subject;
var existingUser = await _userManager.Users.FirstOrDefaultAsync(x => x.UserName == userName || x.Email == email || x.Us_DisplayName == displayName);
if(existingUser != null)
{
if(existingUser.Email == email)
{
return CreateUserObject(existingUser);
}else
{
ModelState.AddModelError("username", "Username taken");
return ValidationProblem();
}
}
var user = new AppUser
{
Us_DisplayName = displayName,
Email = email,
UserName = userName,
Us_Active = true,
Us_Customer = true,
Us_SubscriptionDays = 0
};
var result = await _userManager.CreateAsync(user);
if (result.Succeeded)
{
return CreateUserObject(user);
}
return BadRequest(result.Errors);
}
```
Only the changes from the previous method is this line ` var email = payload.Email;
var displayName = payload.Name;
var userName = payload.Subject;`
Now, i am directly mapping the required params to save in db. This smoothen the process of login instead of checking as in the previous method here ` if (payload.Email != googleRegisterDto.Email)
{
return Unauthorized(new { Error = "Email doesnt match google token" });
}`
And accordingly my GoogleRegisterDto now is
```
public class GoogleRegisterDto
{
[Required]
public string GoogleTokenId { get; set; }
}
```
Now, we need to add these lines in our Program.cs in order to avoid cross origin opener policy error and cross response embedder policy error.
```
app.Use(async (context, next) =>
{
context.Response.Headers.Add("Cross-Origin-Opener-Policy", "same-origin");
context.Response.Headers.Add("Cross-Origin-Embedder-Policy", "require-corp");
await next();
});
```
By incorporating COOP and COEP headers, we can enhance security of our app by preventing potential cross origin attack. These headers help isolate our document context and ensure only trusted resources are embedded, reducing the risk of data leaks and malicious code execution.
More can be read here.
Ref1- https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Cross-Origin-Embedder-Policy
Ref2- https://web.dev/articles/why-coop-coep#:~:text=Cross%20Origin%20Opener%20Policy%20(COOP,pop%2Dup%2C%20its%20window.
There are many aspects of improving upon security aspect and the action should be proactive. Further improvement on this is implementation of refresh token and only allowing known ip's.
But, this is basic set up to get an idea of the flow and get us started. Thanks for your time again!

1,898,495 | Empty Strings and Zero-length Arrays: How do We Store... Nothing? | In high-level languages like Python and JavaScript, we are pretty used to initializing strings and... | 0 | 2024-06-24T06:53:25 | https://dev.to/biraj21/empty-strings-and-zero-length-arrays-how-do-we-store-nothing-1jko | c, javascript, python, beginners | In high-level languages like Python and JavaScript, we are pretty used to initializing strings and arrays like this:
```javascript
let myStr = ""; // an empty string
let myArr = []; // an empty array
```
We're saying that these are empty, which implies they contain zero bytes of data. So we are storing zero-bytes of data? Huh? Tf is this paradoxical nonsense?
## Storing Nothing
An empty array or string doesn't contain any elements or characters, yet it exists. This can feel as paradoxical as carrying an invisible suitcase that weighs nothing. But how do we make sense of this? *drumrolls* Actually, it's NOT really empty.
## Strings: The C Language Perspective
To unravel this mystery, let's take a trip to the world of C programming. In C, strings are typically handled as arrays of characters ending with a null character (`'\0'`). But what happens when you want an empty string?
When you create an empty string in C, you are essentially allocating a string that points to a memory location that stores the null character. This is akin to reserving a seat at a table for a ghost. The chair is there, the place is set, but nobody's coming to dinner. Reminds me of my last date.
Here's a simple representation in C:
```c
char emptyString[1] = "";
```
In this example, `emptyString` is an array with a single element (notice the [1]in the declaration), which is the null terminator. The length of the string is zero, but the array `emptyString` itself is very much real and occupies memory. It's like having an address to an empty house.
In C, the length of a string is determined by iterating through each character until the null terminator (`'\0'`) is encountered. This is exactly what the strlen() function does. It counts characters until it finds the null byte, excluding the terminator itself.
> The strlen() function calculates the length of the string pointed to by s, excluding the terminating null byte (`'\0'`).
So strlen(emptyString) will start the counter with 0 but immediately reach the null byte, resulting in a length of 0.
## Zero-Length Arrays
In C, arrays are typically fixed in size once declared. So first let's C (ok sorry, see) how we can implement a dynamic or growable array of integers using a struct:
```C
struct IntArray {
int *data; // pointer to the array's data
int length; // current number of elements in the array
int capacity; // maximum capacity of the array
};
```
Here, `IntArray` represents a C struct that manages an array of integers. It consists of:
- data: A pointer to the array's data (which can dynamically grow).
- length: The current number of elements in the array.
- capacity: The maximum capacity of the array, indicating how many elements can be stored before needing to resize.
Unlike traditional fixed-size arrays, instances of `IntArray` can dynamically adjust their size as elements are added or removed, akin to how arrays work in higher-level languages like Python or JavaScript. However, in C, this flexibility comes with added responsibility. Developers must manually manage memory allocation and resizing. They need to track the array's length when pushing or popping elements.
When an `IntArray` is initialized, memory is allocated based on the capacity in bytes, and the address of the allocated memory is stored in the data pointer. The length field is then set to zero. This process is analogous to what higher-level languages like JavaScript do internally when you create an empty array.
## Why This Matters
Knowing that an empty string in C is just a pointer that points to `'\0'` character feels good. Curiosity is reason enough! Here's what I tweeted today:

## Twilio and AI
This project utilizes Twilio Voice and Twilio Functions to progress the player through the game. The project also leverages [OpenAI](https://platform.openai.com/) GPT-4o, [ReplicaStudios](https://www.replicastudios.com/) Speech to Speech, and [ElevenLabs](https://elevenlabs.io/) Voice Lab.
**System Design:**
**Here’s the breakdown:**
- 📞 Players submit their phone numbers on our site, triggering an initial call using Twilio Voice.
- 🤖 A riddle is generated by an OpenAI, GPT-4o Assistant, specialized to sound like The Riddler in tone.
- 🤖 The generated text is then converted to audio using a voice created with ElevenLabs Text-to-Speech.
- 🎙️ We recorded audio with the character’s speech patterns, inflection, and dialogue in mind. Using ReplicaStudios Speech to Speech we created our Riddler character voice.
- 🎙️ That voice was then cloned and tweaked for a more natural-sounding reading voice using ElevenLabs Voice Lab.
- 🎙️ Once the audio files are generated from the voice lab, a media tools library called FFMPEG is used to layer backgrounds and sounds effects with the voice work, tweak the audio levels, and combine everything into 3 distinct audio files.
- 📲 Players receive phone calls to hear the riddle, read in the character's voice, using Twilio Voice. A Twilio Function sends a message containing the generated text, and players submit their answers on the site.
- ✅ The submission is verified against the riddle’s answer, and the player receives a call to confirm if they won or need to try again.

1,898,493 | Creating a CRUD App With Go | Introduction Hello! 😎 In this tutorial I will show you how to build a CRUD app using the... | 0 | 2024-06-24T06:51:51 | https://ethan-dev.com/post/creating-a-crud-app-with-go | go, beginners, crud, tutorial | ## Introduction
Hello! 😎
In this tutorial I will show you how to build a CRUD app using the Go programming language. By the end, you'll have a fully functioning CRUD (Create, Read, Update, Delete) app running locally. Let's get started.
---
## Requirements
- Go installed
- Basic understanding of Go
---
## Setting up the project
Create a new directory for the project and navigate into it:
```bash
mkdir crud-app && cd crud-app
```
Next we will initialize the go module and install the dependencies:
```bash
go mod init go-crud-app
go get -u github.com/gorilla/mux
```
Now that the project and required packages are installed we can start working on the application. 😸
---
## Coding the Application
Create a new file called "main.go" and import the following:
```go
package main
import (
"encoding/json"
"log"
"net/http"
"strconv"
"github.com/gorilla/mux"
)
```
- encoding/json: For encoding and decoding JSON data
- log: For logging errors
- net/http: For building the HTTP server
- strconv: For converting strings to integers
- github.com/gorilla/mux: A popular package for routing HTTP requests
Next we define our global variables like so:
```go
var memos []Memo
var idCounter int
```
- memos: A slice that will store all our memos
- idCounter: A counter to keep track of memo IDs
Now we need to create a struct to define a memo:
```go
type Memo struct {
ID int `json:"id"`
Title string `json:"title"`
Content string `json:"content"`
}
```
Next we will create handlers for each of the CRUD operations, the first one will handle create a new memo:
```go
func createMemo(w http.ResponseWriter, r *http.Request) {
var memo Memo
json.NewDecoder(r.Body).Decode(&memo)
idCounter++
memo.ID = idCounter
memos = append(memos, memo)
json.NewEncoder(w).Encode(memo)
}
```
- Decode the JSON request body into a memo struct
- Increment the idCounter and assign a new memo
- Append the new memo to the memos slice
- Encode and return the created memo as a JSON response
The next function will handle getting all the memos:
```go
func getMemos(w http.ResponseWriter, r *http.Request) {
json.NewEncoder(w).Encode(memos)
}
```
- Encode and return the memos slice as a JSON response
Below is the handler to handle getting a single memo:
```go
func getMemo(w http.ResponseWriter, r *http.Request) {
params := mux.Vars(r)
id, _ := strconv.Atoi(params["id"])
for _, memo := range memos {
if memo.ID == id {
json.NewEncoder(w).Encode(memo)
return
}
}
http.Error(w, "Memo not found", http.StatusNotFound)
}
```
- Retrieve the id from the URL parameters
- Search for the memo with the matching ID in the memos slice
- Return the memo if found, otherwise returns a 404 error
The next function handles updating a memo:
```go
func updateMemo(w http.ResponseWriter, r *http.Request) {
params := mux.Vars(r)
id, _ := strconv.Atoi(params["id"])
for i, memo := range memos {
if memo.ID == id {
json.NewDecoder(r.Body).Decode(&memo)
memo.ID = id
memos[i] = memo
json.NewEncoder(w).Encode(memo)
return
}
}
http.Error(w, "Memo not found", http.StatusNotFound)
}
```
- Retrieve the id from the URL parameters
- Search for the memo with the matching ID in the memos slice
- Decode the JSON request body into the found memo and update it
- Return the updated memo as a JSON response or return a 404 error if not found
Lastly we need a function to handle the delete operation:
```go
func deleteMemo(w http.ResponseWriter, r *http.Request) {
params := mux.Vars(r)
id, _ := strconv.Atoi(params["id"])
for i, memo := range memos {
if memo.ID == id {
memos = append(memos[:i], memos[i+1:]...)
json.NewEncoder(w).Encode("The memo was deleted successfully")
return
}
}
http.Error(w, "Memo not found", http.StatusNotFound)
}
```
- Retrieve the id from the URL parameters
- Search for the memo with the matching ID in the memos slice
- Delete the memo by removing it from the slice
- Return a success message or a 404 error if the memo is not found
Next we need to set up the routes to handle each of the CRUD requests:
```go
func initializeRouter() {
router := mux.NewRouter()
router.HandleFunc("/memos", createMemo).Methods("POST")
router.HandleFunc("/memos", getMemos).Methods("GET")
router.HandleFunc("/memos/{id}", getMemo).Methods("GET")
router.HandleFunc("/memos/{id}", updateMemo).Methods("PUT")
router.HandleFunc("/memos/{id}", deleteMemo).Methods("DELETE")
log.Fatal(http.ListenAndServe(":8000", router))
}
```
- Initialize a new router using mux.NewRouter
- Define routes for each CRUD operation and map them to the respective handlers
- Start the HTTP server on port 8000
Finally we need to implement the main function, as so:
```go
func main() {
memos = append(memos, Memo{ID: 1, Title: "First memo", Content: "Hello World"})
idCounter = 1
initializeRouter()
}
```
- Initialize the memos slice with a sample memo
- Set the idCounter to 1
- Call the previous initializeRouter function to start the server
Done! Now we can move onto testing the application. 😆
---
## Testing the Application
First we need to start the server before we can make requests to it, this is done via the following command:
```bash
go run main.go
```
Now we can use the following CURL commands to test each of the endpoints.
Create a memo:
```bash
curl -X POST -d '{"title":"New Memo","content":"This is a new memo."}' -H "Content-Type: application/json" http://localhost:8000/memos
```
Get all memos:
```bash
curl http://localhost:8000/memos
```
Get a memo by it's ID:
```bash
curl http://localhost:8000/memos/1
```
Update a memo:
```bash
curl -X PUT -d '{"title":"Updated Memo","content":"This is an updated memo."}' -H "Content-Type: application/json" http://localhost:8000/memos/1
```
Delete a memo:
```bash
curl -X DELETE http://localhost:8000/memos/1
```
Feel free to change the contents and have a play around with it. 👀

## What I Built
Hault is an open-source software that helps connect database that contains information about your business and FAQs that help you automate customer support using AI.
<!-- INTRODUCTION -->
## Introduction
- The project is mainly a WhatsApp bot which you can scroll down and host via one click deploy on render by pressing `Deploy on render` and the user can talk to the application via WhatsApp to whatever number you have configured on twilio.
- In my case, you can check the bot out right now by messaging me at (+13476958493)
Since the number is blocked because of WhatsApp verification problem you can check the website out and try the project to do so you will need to log in via Google and you will need to ask the admin permission via email at `capja778@gmail.com`
then head over to [https://hault.vercel.app/login](https://hault.vercel.app/login)
- I keep it as raw as possible so that the people using this project find it easy to host and edit the website too.
Here are some of the screenshots of the application
## How to host the software for your business?
:1. First get the following authentication token and api keys from the following services
- Google Gemini API key
- Airtable account Table id, base id, api key
- Twilio account sid , phone number and auth token
well actually i added 2 AI servuce that is gemini and workers ai which can be switched using LLM variable set to either GEMINIAI or WORKERAI.But for ease we will use gemini ai for now.
Same for database plan was to in corporate Mongodb too but we are only gonna use Airtable for now so set UI as AIRTABLE
For twilio you will need to create a whatsapp sender by purchasing a number, then create a service there you will choose the number, then in integration section choose webhook and add the call back url as
`your_url+/api/v1/twilio/message`
in status add
`your_url+/api/v1/twilio/status`
we will get the url after deployment
So overall you will need these values
```
LLM=GEMINIAI
UI=AIRTABLE
OWNER_EMAIL
OWNER_PHONE_NUMBER
TWILIO_PHONE_NUMBER
TWILIO_ACCOUNT_SID
TWILIO_AUTH_TOKEN
AIRTABLE_TABLE_ID
AIRTABLE_BASE_ID
AIRTABLE_API_KEY
```
Let everything else stay empty or add "123" as a dummy value when inputting in the deployment.
:2. Go to my repo [https://github.com/captain0jay/Hault](https://github.com/captain0jay/Hault)
and click the deploy on render button
:3. Then you will be redirected to render website where the values we got will be inputted
:4. Then just press launch button and your application will be live and your customers can start messaging and take the benefit of AI customer support
:5. One last step as we discussed earlier that in console.twilio.com -> messaging -> service -> your_created_service -> integration
the call back url as
`your_url+/api/v1/twilio/message`
in status add
`your_url+/api/v1/twilio/status`
- here add your_url as the one that you got in hosted application see below image as reference
## Demo
So you can check the bot out right now by messaging at (+13476958493) and ask about Hault that is the project itself.
Since the number is blocked because of whatsapp verification problem you can check the website out and try the project to do so you will need to login via Google and you will need to ask the admin permission via email at `capja778@gmail.com`
then head over to [https://hault.vercel.app/login](https://hault.vercel.app/login)
Below is the repo
{% embed https://github.com/captain0jay/Hault %}
## Tech stack
For backend - Nodejs
For frontend - Nextjs, Shadcn
Main services - Twilio
AI - Gemini
Database - Airtable
## Twilio and AI
<!-- Tell us how you leveraged Twilio’s capabilities with AI -->
Twilios whatsapp and SMS functionalities were very helpful in making the software as the code required is very minimal
I connected airatble database and fetched the details from the database feeding it to Gemini AI and then final step was to give response back to twilio after webhook is called and all it took for twilio to connect is 5 lines of code
```
router.post('/message', async (req, res) => {
const userMessage = req.body.Body || "hi";
const twiml = new MessagingResponse();
let response = await getChat(userMessage);
twiml.message(response);
res.type('text/xml').send(twiml.toString());
});
```

Let’s explore how to set up IronPDF and utilize its features to sign your PDF documents effectively.
### Prerequisites
Before you can start signing PDFs with IronPDF, make sure you have the following prerequisites in place:
1. Ensure you have a .NET development environment set up. This includes having Visual Studio installed on your machine. You can download Visual Studio from the [official website](https://visualstudio.microsoft.com/).
2. A running C# program (Any template)
3. Have a sample PDF document ready for testing the signing process. This can be any PDF file you want to experiment with.
4. To sign a PDF document, you will need a digital certificate (PFX file). You can obtain a digital certificate from a trusted certificate authority (CMS Advanced Electronic Signatures). Ensure you have the certificate file and its password.
5. Familiarity with C# programming is essential, as you will be writing code to implement PDF signing functionality.
With these prerequisites in place, you'll be ready to use IronPDF to add digital signatures to your PDF documents, ensuring their authenticity and security.
### Step 1: Installing the IronPDF Library
Assuming you already have a C# console project set up, the next step is to install the IronPDF library. Follow these steps to get IronPDF up and running in your project:
1. Launch Visual Studio and open your existing C# console project.
2. In the top menu, navigate to Tools > NuGet Package Manager > Manage NuGet Packages for Solution.
3. In the NuGet Package Manager, go to the Browse tab and type "IronPDF" into the search box.
4. Select the IronPDF package from the search results and click the Install button. Accept any license agreements if prompted.
5. If you prefer to install it using NuGet Package Console, use the following command:
```
Install-Package IronPdf
```
This command will download and install the IronPDF library into your project, making it ready for use.
Once IronPDF is installed, you can start using its features to work with PDF documents, including signing them digitally. Make sure to include the necessary directive at the top of your code file:
```
using IronPdf;
```
With IronPDF successfully added to your project, you're now ready to move on to loading a PDF document and implementing the functionality to sign it.
### Step 2: Load PDF Document
Now that you've installed the IronPDF library in your C# console project, the next step is to load an existing PDF document. IronPDF provides a straightforward way to do this. You can load your PDF document from a file path using the PdfDocument class provided by IronPDF. Here's an example:
```
// Path to your PDF file
string pdfPath = @"C:\path\to\your\document.pdf";
// Load the PDF document
PdfDocument pdf = PdfDocument.FromFile(pdfPath);
// Output message to confirm loading
Console.WriteLine("PDF loaded successfully!");
```
In this code snippet, PdfDocument.FromFile(pdfPath) is used to load the PDF from the specified file path. Once the document is loaded, you can perform various operations on it, such as extracting text, adding annotations, or preparing it for digital signing. The Console.WriteLine statement confirms that the PDF has been loaded successfully, allowing you to proceed with further processing.
### Step 3: Load PDF Signature
After loading your PDF document, the next step is to load and configure the digital signature. IronPDF makes this process straightforward. You can load a signature from a PFX file, configure various properties, and apply it to your PDF. In this example, we'll use a sample PFX file named IronSoftware.pfx with the password 123.
```
// Path to your PFX file and its password
string pfxPath = @"C:\path\to\Iron.pfx";
string pfxPassword = "123";
// Load and configure the PDF signature
var signature = new PdfSignature(pfxPath, pfxPassword)
{
SigningContact = "support@ironsoftware.com",
SigningLocation = "New York, USA",
SigningReason = "Security Reasons"
};
// Output message to confirm signature loading
Console.WriteLine("PDF signature loaded successfully!");
```
In this code snippet:
- PdfSignature(pfxPath, pfxPassword) initializes the digital signature using the specified PFX file and password.
- SigningContact, SigningLocation, and SigningReason are properties that provide additional information about the signature, which can be useful for verification purposes.
After loading and configuring the signature, you can proceed to apply it to your PDF document.
### Step 4: Apply Signature To PDF Document
After loading and configuring your digital signature, the final step is to apply this signature to your PDF document using IronPDF. This step will make your PDF is digitally signed and secure. Here’s how you can do it:
```
// Apply the signature to the PDF
pdf.Sign(signature);
```
### Step 5: Save the Signed PDF File
After applying the digital signature to your PDF document, the final step is to save the signed PDF to a new file. This ensures that your document is securely stored with its new digital signature. Here’s how you can do it:
```
// Save the signed PDF to a new file
string signedPdfPath = @"C:\path\to\your\signed_document.pdf";
pdf.SaveAs(signedPdfPath);
// Output message to confirm the signing process
Console.WriteLine("PDF signed and saved successfully!");
```
This step completes the process of digitally signing a PDF document using IronPDF in C#. Your signed PDF is now saved and ready for use, ensuring its integrity and authenticity.
###Verify PDF Digital Signatures
After running the program, the PDF is signed and saved at the specified path. Below is the screenshot of the signed PDF file. You can see the signature details indicating the document has been successfully signed.
In the screenshot, you can see that the digital signature in the signature field is marked as valid, along with the signing details such as the signer's identity, the location, and the reason for signing. This confirms that the signing process was completed successfully using IronPDF.
### Complete Code
Here is the complete code for loading, signing, and saving a PDF document using IronPDF in a C# console application:
```
using IronPdf;
using IronPdf.Signing;
class Program
{
static void Main(string[] args)
{
License.LicenseKey = "License-Key";
// Path to your PDF file
string pdfPath = "sample.pdf";
// Load the PDF document
PdfDocument pdf = PdfDocument.FromFile(pdfPath);
// Path to your PFX file and its password
string pfxPath = @"Iron.pfx";
string pfxPassword = "123";
// Load and configure the PDF signature
var signature = new PdfSignature(pfxPath, pfxPassword)
{
SigningContact = "support@ironsoftware.com",
SigningLocation = "New York, USA",
SigningReason = "Security Reasons"
};
// Apply the signature to the PDF
pdf.Sign(signature);
// Save the signed PDF to a new file
string signedPdfPath = "signed_document.pdf";
pdf.SaveAs(signedPdfPath);
// Output message to confirm the signing process
Console.WriteLine("PDF signed and saved successfully!");
}
}
```

1,898,487 | Creating an Interactive Airbnb Chatbot with Lyzr, OpenAI and Streamlit | In the competitive landscape of the hospitality industry, providing exceptional guest experiences is... | 0 | 2024-06-24T06:44:47 | https://dev.to/harshitlyzr/creating-an-interactive-airbnb-chatbot-with-lyzr-openai-and-streamlit-55bg | In the competitive landscape of the hospitality industry, providing exceptional guest experiences is crucial for retaining customers and gaining positive reviews. Airbnb hosts face the challenge of addressing numerous queries from guests promptly and accurately. Common questions range from property rules and amenities to local recommendations and troubleshooting issues during their stay. Managing these interactions manually can be time-consuming and prone to inconsistencies, especially for hosts managing multiple properties or those who are frequently unavailable to respond immediately.
Airbnb hosts need an efficient, reliable, and consistent way to address guest inquiries to enhance their stay experience. Traditional methods of communication, such as emails and phone calls, can lead to delays and miscommunications. There is a clear need for an automated solution that can provide guests with quick, accurate, and friendly responses to their queries about the property and surrounding area.
The objective is to develop an intelligent chatbot integrated into a Streamlit web application that leverages OpenAI’s API to handle guest inquiries. The chatbot should be able to:
Provide accurate and relevant answers to common questions about the Airbnb property, such as wifi credentials, house rules, check-in/check-out times, and amenities.
Offer personalized local recommendations based on the host’s knowledge.
Operate with a welcoming, friendly, and attentive personality to ensure a positive guest interaction.
Maintain consistency and reliability in the information provided to guests.
We propose the development of the “Airbnb Chatbot,” a Streamlit-based web application that integrates the Lyzr QABot with OpenAI’s API. This chatbot will be trained on a comprehensive FAQ document related to the Airbnb property and will follow a predefined prompt that outlines its personality and response style. The chatbot will:
Utilize advanced natural language processing capabilities to understand and respond to guest inquiries.
Be accessible to guests 24/7 through a user-friendly interface.
Ensure that responses are based strictly on the provided data to avoid misinformation.
**Key Metrics for Success:**
Response Time: Average time taken to respond to guest queries.
Guest Satisfaction: Measured through feedback and ratings.
Consistency: Accuracy and reliability of the information provided by the chatbot.
Usage Rate: Frequency of guest interactions with the chatbot.
**Prerequisites**
Before we dive into the code, make sure you have the following:
Python 3.8+ installed.
Streamlit installed (pip install streamlit).
OpenAI API Key.
Lyzr library installed (pip install lyzr).
dotenv library for loading environment variables (pip install python-dotenv).
PIL (Pillow) for image processing (pip install pillow).
**Setting Up the Environment**
First, ensure that your OpenAI API key is stored in a .env file:
```
OPENAI_API_KEY=your_openai_api_key_here
```
Importing Libraries and Loading Environment Variables:
```
import os
from lyzr import QABot
import openai
from dotenv import load_dotenv
from PIL import Image
load_dotenv()
openai.api_key = os.getenv("OPENAI_API_KEY")
```
The code starts by importing necessary libraries:
streamlit as st: for building the Streamlit application.
os: for interacting with the operating system.
lyzr and QABot: for using Lyzr's question answering capabilities.
openai: (commented out) potentially for integration with OpenAI services.
dotenv: for loading environment variables (likely containing an OpenAI API key).
It then loads environment variables using load_dotenv() (likely for the OpenAI API key).
An OpenAI API key is set using os.getenv("OPENAI_API_KEY"), but it's currently commented out.
**Defining the Chatbot Personality:**
```
prompt=f"""
You are an Airbnb host with a welcoming, friendly, and attentive personality.
You enjoy meeting new people and providing them with a comfortable and memorable stay.
You have a deep knowledge of your local area and take pride in offering personalized recommendations.
You are patient and always ready to address any concerns or questions with a smile.
You ensure that your space is clean, cozy, and equipped with all the essentials.
Your goal is to create a home away from home for your guests and to make their stay as enjoyable and stress-free as possible.
When responding to guest questions, provide clear, helpful, and friendly answers based strictly on the provided data.
[IMPORTANT]Do not give answers outside of the given information.
"""
```
A variable prompt is defined as a string containing the desired personality and functionalities for the Lyzr QABot.
**Implementing the Chatbot Functionality:**
```
@st.cache_resource
def rag_implementation():
with st.spinner("Generating Embeddings...."):
qa = QABot.pdf_qa(
input_files=["airbnb.pdf"],
system_prompt=prompt
)
return qa
st.session_state["chatbot"] = rag_implementation()
```
A function rag_implementation() is defined using @st.cache_resource. This function uses Streamlit caching to avoid redundant computations.
It displays a spinner message “Generating Embeddings…” while the code executes.
Inside the function, it creates a QABot instance using QABot.pdf_qa().
It specifies the input file “airbnb.pdf” containing Airbnb information and FAQs.
It sets the system prompt to the previously defined prompt to guide the chatbot's responses.
The function returns the created QABot object.
**Managing Chat State and User Interactions:**
```
if "messages" not in st.session_state:
st.session_state.messages = []
for message in st.session_state.messages:
with st.chat_message(message["role"]):
st.markdown(message["content"])
if "chatbot" in st.session_state:
if prompt := st.chat_input("What is up?"):
st.session_state.messages.append({"role": "user", "content": prompt})
with st.chat_message("user"):
st.markdown(prompt)
with st.chat_message("assistant"):
response = st.session_state["chatbot"].query(prompt)
chat_response = response.response
response = st.write(chat_response)
st.session_state.messages.append(
{"role": "assistant", "content": chat_response}
)
```
The code retrieves the chatbot instance from the session state (st.session_state["chatbot"]) using the result of rag_implementation().
It checks if a key “messages” exists in the session state. If not, it initializes an empty list for messages (st.session_state.messages = []).
The code iterates through the existing messages in the session state and displays them using st.chat_message() with the message role ("user" or "assistant") and content.
The code checks if the chatbot instance exists in the session state.
If the chatbot exists, it displays a chat input box using st.chat_input() with a prompt "What is up?".
If the user enters a message, it’s stored in the session state messages list with the user role (“user”). The message is also displayed with st.chat_message().
With another st.chat_message(), the code calls the chatbot's query() method with the user message to get a response.
The chatbot response is stored in a variable chat_response.
The response is displayed on the screen using st.write().
Finally, the chatbot response is added to the session state messages with the assistant role (“assistant”).
**Running the App:**
To run the Streamlit app, save the code in a file (e.g., app.py) and use the following command:
```
streamlit run app.py
```

1,898,479 | Changing State After Defining it using Const ??!! What Is Going On? | Have you asked yourself how you can change the state you defined in spite of using const declarations... | 0 | 2024-06-24T06:40:05 | https://dev.to/ahmedeweeskorany/changing-state-after-defining-it-using-const-what-is-going-on-3j0i | webdev, javascript, react, programming | Have you asked yourself how you can change the state you defined in spite of using const declarations like `const [count,setCount] = useState(0)`? let's dive a little bit ...
#### The first question we need to ask is that does the const declarations make variables immutable.
actually, const creates something called ` constant reference to the value ` which states that you can't change the reference of the variable but if you have an object or array you can easily edit it. so the real answer to the previous question is `No`. Now let's back to our main topic:
we have received two variables from useState hook `(by Destructuring)` so according to the above content we can't edit on `count` variable, can we?
the answer is that we can't edit on `count` variable directly without using `setCount` and if you try to do that, you'll receive a Type Error indicating that count is a constant variable as shown in the main image.
so, what is the magic that `setCount` is making ?
well, `setCount` is a function provided by reacting and using its mechanisms like (virtual DOM..etc) to change the value of `count` variable.
####thank you for reaching this point.

In the following table, value of cell A1 is made up of names of several people and their attendances in four days. For example, c is 1100 expressed in hexadecimal notation, meaning the corresponding person has attendance in the 1st day and the 2nd day and is absent in the 3rd day and the 4th day.
We need to find the number of people who has the attendance in the day input in A2. For example, three people are present in the 1st day and two people are present in the 3rd day.
**Solution**:
Use **SPL XLL** to type in the following formula:
```
=spl("=theDay=shift(1,?2-4),?1.split@c().step(2,2).count(and(bits@h(~),theDay)>0)",A1,A2)
```
As shown in the picture below:
**Explanation**:
shift()function performs a shift operation on an integer. step(2,2) gets members at the even positions. bits@h parses a hexadecimal number. The and operator represents and "AND" operation with bits() function, and ~ represents the current member. | judith677 |

from openai import OpenAI
from lyzr_automata.data_models import FileResponse
from lyzr_automata.utils.resource_handler import ResourceBox
class GPTVISION(AIModel):
def __init__(self, api_key, parameters: Dict[str, Any]):
self.parameters = parameters
self.client = OpenAI(api_key=api_key)
self.api_key = api_key
def generate_text(
self,
task_id: str=None,
system_persona: str=None,

messages=messages,
)
return response.choices[0].message.content
def generate_image(
self, task_id: str, prompt: str, resource_box: ResourceBox
) -> FileResponse:
pass
```
This code defines a class GPTVISION that inherits from Lyzr Automata'sAIModel. It interacts with the OpenAI API to generate text based on user prompts and potentially images.
It takes an API key and parameters during initialization.
The generate_text function builds a message containing the prompt and optionally an image URL.
It sends this message to the gpt-4o model for text completion and returns the generated response.
The generate_image function is not implemented here.
**App.py**
```
from gptvision import GPTVISION

**Step-by-Step Guide**
**Setting Up the App:**
```
pip install lyzr-automata streamlit pillow
```
**gptvision.py**
```
from typing import Any, Dict, List
from lyzr_automata.ai_models.model_base import AIModel
from openai import OpenAI
from lyzr_automata.data_models import FileResponse
from lyzr_automata.utils.resource_handler import ResourceBox
class GPTVISION(AIModel):
def __init__(self, api_key, parameters: Dict[str, Any]):
self.parameters = parameters
self.client = OpenAI(api_key=api_key)
self.api_key = api_key
def generate_text(
self,
task_id: str=None,
system_persona: str=None,
prompt: str=None,
image_url: str=None,
messages: List[dict] = None,
):
if messages is None:
messages = [
{"role": "user", "content": [
{"type": "text",
"text": prompt
},
{
"type": "image_url",
"image_url": {
"url": f"data:image/jpeg;base64,{image_url}",
},
},
]
},
]
response = self.client.chat.completions.create(
**self.parameters,
model="gpt-4o",
messages=messages,
)
return response.choices[0].message.content
def generate_image(
self, task_id: str, prompt: str, resource_box: ResourceBox
) -> FileResponse:
pass
```
This code defines a class GPTVISION that inherits from Lyzr Automata'sAIModel. It interacts with the OpenAI API to generate text based on user prompts and potentially images.
It takes an API key and parameters during initialization.
The generate_text function builds a message containing the prompt and optionally an image URL.
It sends this message to the gpt-4o model for text completion and returns the generated response.
The generate_image function is not implemented here.
**App.py**
```
from gptvision import GPTVISION
import streamlit as st
from PIL import Image
import utils
import base64
import os
```
Imports necessary libraries like GPTVISION from gptvision, streamlit for the web app, PIL for image processing, and utility functions from utils.Imports necessary libraries like GPTVISION from gptvision, streamlit for the web app, PIL for image processing, and utility functions from utils.
**OpenAI API Key Validation:**
```
api = st.sidebar.text_input("Enter Your OPENAI API KEY HERE",type="password")
if api:
openai_4o_model = GPTVISION(api_key=api,parameters={})
else:
st.sidebar.error("Please Enter Your OPENAI API KEY")
```
Takes user input for their OpenAI API key through a password field in the sidebar.
Checks if the API key is entered.
If not, displays an error message in the sidebar asking the user to enter the key.
**Uploading Construction Map:**
```
data = "data"
os.makedirs(data, exist_ok=True)
def encode_image(image_path):
with open(image_path, "rb") as image_file:
return base64.b64encode(image_file.read()).decode('utf-8')
```
Creates a folder named data to store uploaded files.
Defines a function encode_image that takes an image path, opens the image in binary mode, and encodes it to base64 format for sending to the OpenAI API.
**GPT Model and Prompt:**
```
prompt = f"""
Please analyze the uploaded image of our factory site. Identify and highlight potential safety hazards based on Industrial Safety Regulations(Occupational Safety and Health Administration (OSHA) standards) such as unguarded machinery, tripping hazards, missing safety signs, and workers not using PPE.
Provide a detailed report suggesting specific safety measures to mitigate each identified risk.
Ensure the suggestions comply with current industrial safety regulations and prioritize actions based on the severity of the hazards.
Output Requirements:
1/ Potential Safety Hazards
2/ Detailed Safety Measures
3/ Prioritization of Actions
1/ Immediate
2/ short-term
3/ long-term
IF IMAGE IS NOT RELATED TO WORKERS SAFETY OR FACTORY SITE THEN REPLY "Please upload Image related to factory site.This image does not belong to Factory site."""
```
Defines a prompt for the GPTVISION model:
Analyzes the image for hazards based on OSHA standards.
Identifies specific risks and suggests safety measures.
Prioritizes actions based on severity (immediate, short-term, long-term).
Handles cases where the image isn’t relevant to a factory site.
**Uploading and Processing:**
```
if uploaded_files is not None:
st.success(f"File uploaded: {uploaded_files.name}")
file_path = utils.save_uploaded_file(uploaded_files)
if file_path is not None:
st.sidebar.image(file_path)
if st.button("Generate"):
encoded_image = encode_image(file_path)
planning = openai_4o_model.generate_text(prompt=prompt, image_url=encoded_image)
st.markdown(planning)
```
If “Generate” is clicked, encodes the image using the encode_image function.
Calls the openai_4o_model.generate_text function (likely from GPTVISION) with the prompt and encoded image.
This function presumably uses the OpenAI API to analyze the image and generate text based on the prompt.
The generated text containing safety analysis is displayed in the app using st.markdown.

In this article brought to you by [Infrasity](infrasity.com), you’ll learn everything about ReactJS Best Practices, how to assess if a code follows the best practices, which, if not followed, will hinder productivity, increase debugging time, the benefits of following best practices, and how to make it a habit.
Without any further ado, let’s get right into it!
## Prerequisites to learn React
If you want to learn ReactJS, having a good grasp over Javascript is crucial. There are few topics that you don’t want to neglect, let’s layout a list of topics (javascript) that are essential to learn React:
- Map, filter, and reduce array methods
- Functions
- Classes
- Data structures like arrays
- Promises, async/await
- DOM (document object model)]
- Dot (.) operator
- Closures
- arrow functions
- spread (…) operator
- template literals
One of the main benefits of using React is the features like virtual DOM, component-based architecture, and it’s declarative syntax. React's applications include the development of SPAs (single-page applications), web apps, PWAs (progressive web apps), and more. There are various challenges that you, as a React developer may face during the development of webapp, which include state management, performance optimization, code structure management and many more.
Today, we are going to learn about some of the best practices that are key to optimizing your React code, as well as the performance of your app. Understanding ReactJS patterns is important to follow the best practices effectively.
## ReactJS: Best practices 🔑
We have discussed about what React is, it’s applications, and why should a developer implement best practices while writing react code.
Using best practices in React development ensures the maintainability, scalability, and performance of the codebase. Also promoting code readability and understandability, which, as a result, reduces bugs and errors.
As far as best practices are concerned, we at [Infrasity](infrasity.com) keep in mind all the best practices of writing code, inculcating all features of ReactJS effectively, using Linting tools, well-formatted code, making sure that comments are excluded when committing the code, and only necessary comments make it to the commits.
[Infrasity](infrasity.com) has made a lot of demo recipe libraries to assist Devzero, one of our customers, in creating recipe libraries, which helped them in quick developer onboarding.
The recipe libraries created were a combination of different tech stacks, like NodeJs, BunJS, React, and CockroachDB, so that the end users could directly use them as boilerplate code without writing the entire code from scratch. All the code written by developers at [Infrasity](infrasity.com) incorporated clean code principles, making the codebase robust.
Below is an outline of all the ReactJS best practices that we are going to discuss in this blog post:
1. Folder structure management
2. State management
3. React router for multi-page applications
4. Lazy loading
5. Reusable components
6. Using React Hooks effectively
7. Staying updated with new React features.
Let’s get straight into it and discuss each practice one by one!
### 1. Folder Structure management:
A well maintained, and organized folder structure can help you, as well as other developers working together, understand the codebase better, identify various resources used in the project, etc.
This will not only help in scalability, but also with easy navigation throughout the various components.
You can break down functionalities into smaller, reusable modules to keep your codebase clean and organized.
Check the below code snippet for an example:
Another good practice involves grouping similar components (functionalities) in the same folder. Check the below folder structure, where I have grouped the components under the crowdfunding section in a single file:
All of these components should be included in the same folder as they convey similar usage (buttons, forms, campaign details etc).
### 2. State management:
With the development of a webapp, and it’s increasing complexity, basically the size, managing various states and the direction your data flows should be well organized and have a plan. There are several things to keep in mind when managing states in ReactJS, let’s learn about few techniques by which your webapp would become more efficient!
- Keep your state as local as possible: Use local component state for UI-related states and keep it as close to where it is going to be used as possible to minimize the complex nature.
- Use context wherever possible: For application-wide state that needs to be accessed by many components, use the Context API to avoid prop drilling.
[Here’s where to learn more about the context API
](https://legacy.reactjs.org/docs/context.html)
- Limiting component creation: As much as react promotes creation of components for various functionalities, we have to limit this practice as it makes the state flow even more complicated.
**Example:** If an app has 3 child components, LoginPage, HomePage, and featureSection page, its best to include the feature section inside HomePage itself, instead of creating a completely different component.
This practice is more subjective, and will take repetition to perfect.
### 3. Lazy Loading
As the name suggests, lazy loading is a feature in React that delays the loading of components until they are needed, which helps to improve the initial load time of an application by reducing the amount of code that needs to be loaded upfront.
This is especially useful when your codebase is complex, and as it grows, this is a must-have in your React application.
It can be implemented simply by using the snippet React.lazy() when importing a component from another folder.
**But how does this even work?**
There are 3 high-level steps that are involved in Lazy Loading:
1. **Code Splitting:** When you use `React.lazy`, Webpack (or another bundler) splits your code into smaller chunks. Each chunk corresponds to a different part of your application.
2. **Dynamic Import:** The actual code for the lazy-loaded component is only fetched when the component is about to be rendered. This reduces the amount of code that needs to be loaded initially.
3. **Suspense:** While the code for the lazy-loaded component is being fetched, the suspense component displays a fallback UI.
Check out the below example for a more detailed code implementation.
### 4. Re-usable components
These are fundamentals in React if you want to develop scalable and maintainable applications.
Developing re-usable components promote code reusability, reduce redundancy, and enhance consistency across the application.
Here are 2 simple examples of isolating components:
The below component only includes a button, which can be re-used various times for other pages, and sections as well.
Another example includes having props in your component which makes it customizable according to your needs:
Also, we can use the single responsibility principle, which simply means creating a component dedicated to a single functionality that doesn’t contain multiple use-cases. It simply states that a component should have only one reason to change, meaning it should have only one job or responsibility.
### 5. Using React Hooks
Hooks in ReactJS are nothing but functions that help us manage our application, trigger conditional operations, and build a more efficient application.
In React 16.8, hooks provide a more direct API to manage component logic and state without the need for class components.
You can implement hooks to manage the aftereffects of a function, which generally happen after a state is altered. Let’s take a look at 2 of the most common hooks available in ReactJS.
1.**useState:**
It is nothing but an array of two elements, it helps us manage the values of a particular function, or a variable.
useState returns an array with two elements: the current state and a function to update that state. You can use array destructuring to assign these values to variables.
You can see in the below example of how we are creating a state for a variable ‘count’, and incrementing it every time the button is clicked.
2.**useEffect:**
useEffect is a Hook that allows you to perform side effects in function components.
useEffect takes two arguments:
1. A function that contains the side effect logic.
2. An optional array of dependencies.
Below is a simple example where we are displaying error if the data from API is not fetched, and setting the data as the result if otherwise.
### 6. Staying updated with React versions
Staying updated with React version changes will prove beneficial when optimizing your code and webapp.
You will also get informed about the best ways to improve performance and efficiency as well. But how can you, as a developer stay updated with these changes and updates? Well there are certain ways to do so, which include:
**Following Official React Channels**
1. **React Blog:** Regularly check the official React blog for announcements, release notes, and detailed posts about new features.
2. **React Newsletter:** Subscribe to newsletters like React Newsletter for weekly updates on React and its ecosystem.
3. **Social media**: You can follow the official pages on X or stay tuned with the official docs and blogs of ReactJS.
## FAQs
**What is the best way to learn more about React?**
The best way to learn React and write efficient code is simply to practice more and more every day. Sooner or later, you will get used to writing good, readable, and efficient code as a default.
**Why should we follow best practices?**
The main reason to keep these practices in mind is to optimize the performance of your web application while simultaneously improving the quality of the code you write.
**Should a beginner follow these practices?**
While it’s good if you follow and implement these from the very beginning, but your main focus as a beginner should always be learning the workings of React and
understanding the fundamentals.
**Does improving performance matter on a small scale?**
Following these practices works best when we face the issue of scalability and maintaniblity, it is a good practice to ensure applying these even at a smaller scale as well.
**What are the common challenges faced by React developers?**
Some common challenges faced by React developers include state management, performance optimization, code structure management, and ensuring the maintainability of the application as it scales.
**How can I stay updated with the latest React version changes?**
Follow official React channels and blogs and subscribe to newsletters like React Newsletter for weekly updates.
## Conclusion
As a developer, just learning how to code in React isn’t enough, knowing what to code, implementing ReactJS best practices, are going to help you build an efficient, fast, and a light-weight web application.
Here’s a simple summary of all the ReactJS best practices that we learned about today:
**Efficient folder management**
- State management
- Lazy Loading
- Re-usable components
- Using react hooks

A core function within this industry is underwriting — the process of evaluating risks and determining the terms and conditions of insurance policies. Traditional underwriting is often complex, time-consuming, and reliant on manual data processing and expert judgment. This can lead to inconsistencies, delays, and increased operational costs.
**Current Challenges**
Manual Data Processing: Underwriting requires collecting and analyzing a vast amount of data, including personal, health, and lifestyle information. Manual data entry and analysis are prone to errors and inefficiencies.
Inconsistent Decision-Making: Human underwriters may have varying levels of expertise and judgment, leading to inconsistent risk assessments and policy decisions.
Time-Consuming Procedures: The traditional underwriting process can take days or even weeks to complete, causing delays in policy issuance and customer dissatisfaction.
High Operational Costs: Extensive manual processing and the need for specialized underwriters increase the operational costs for insurance companies.
Regulatory Compliance: Ensuring compliance with regulatory requirements is essential but can be challenging and resource-intensive when done manually.
**Insurance Underwriting Expert**
The Insurance Underwriting Expert is an AI-driven application designed to revolutionize the underwriting process. It aims to address the aforementioned challenges by providing a user-friendly platform where insurance companies can:
Automate Data Processing: Utilize AI to collect, verify, and analyze applicant data quickly and accurately.
Ensure Consistent Risk Assessments: Apply standardized AI models to ensure uniform risk evaluations across all applications.
Speed Up Decision-Making: Significantly reduce the time required to assess risks and issue policies.
Lower Operational Costs: Minimize the need for extensive manual labor and specialized underwriters.
Enhance Regulatory Compliance: Implement built-in compliance checks to ensure adherence to regulatory standards.
**How the Insurance Underwriting Expert Works**
Our AI-powered underwriting solution utilizes Lyzr Automata and OpenAI to evaluate applicant data and generate comprehensive underwriting reports. Here’s a step-by-step guide on how to use our tool:
1. Enter Applicant Information
The process begins with collecting basic information about the applicant, including their name, age, and address. This step is crucial for establishing the applicant’s identity and context.
2. Provide Personal and Health Information
Next, we gather detailed personal and health information. This includes the applicant’s occupation, annual income, marital status, medical history, dependents, lifestyle, and family medical history. This data is essential for assessing the overall risk profile of the applicant.
3. Generate the Underwriting Report
Once the data is entered, our AI system processes the information to calculate a risk status (low, neutral, or high). Based on this risk status, it generates a detailed underwriting report. This report includes:
Risk Assessment Summary: An overview of the risk score and factors contributing to it.
Underwriting Decision: A summary of the underwriting decision based on the risk assessment.
Policy Terms and Conditions: Detailed terms and conditions of the proposed policy, including coverage amount, premium calculation, payment options, policy riders, exclusions, and more.
Approval Conditions: Conditions that must be met for the policy to be approved.
Policy Issuance Details: Information about the effective date, renewal date, and beneficiary designation.
**Setting Up the Environment**
**Imports:**
Imports necessary libraries: os, streamlit, libraries from lyzr_automata, and dotenv.
```
pip install lyzr_automata streamlit
```
```
import streamlit as st
from lyzr_automata.ai_models.openai import OpenAIModel
from lyzr_automata import Agent,Task
from lyzr_automata.pipelines.linear_sync_pipeline import LinearSyncPipeline
from PIL import Image
```
**API Key Input:**
```
api = st.sidebar.text_input("Enter our OPENAI API KEY Here", type="password")
if api:
openai_model = OpenAIModel(
api_key=api,
parameters={
"model": "gpt-4-turbo-preview",
"temperature": 0.2,
"max_tokens": 1500,
},
)
else:
st.sidebar.error("Please Enter Your OPENAI API KEY")
```
Creates a text input field in the sidebar using st.sidebar.text_input to capture the OpenAI API key. It hides the input text using the type="password" argument.
Conditionally checks for the entered API key:
If a key is entered, it creates an OpenAIModel object using the provided parameters (model name, temperature, and maximum tokens).
If no key is entered, it displays an error message using st.sidebar.error.

1,898,470 | Minimizing GPU RAM and Scaling Model Training Horizontally with Quantization and Distributed Training | Training multibillion-parameter models in machine learning poses significant challenges, particularly... | 0 | 2024-06-24T06:31:55 | https://victorleungtw.com/2024/06/24/quantization/ | quantization, gpu, training, scalability | Training multibillion-parameter models in machine learning poses significant challenges, particularly concerning GPU memory limitations. A single NVIDIA A100 or H100 GPU, with its 80 GB of GPU RAM, often falls short when handling 32-bit full-precision models. This blog post will delve into two powerful techniques to overcome these challenges: quantization and distributed training.
### Quantization: Reducing Precision to Conserve Memory
Quantization is a process that reduces the precision of model weights, thereby decreasing the memory required to load and train the model. This technique projects higher-precision floating-point numbers into a lower-precision target set, significantly cutting down the memory footprint.
#### How Quantization Works
Quantization involves the following steps:
1. **Scaling Factor Calculation**: Determine a scaling factor based on the range of source (high-precision) and target (low-precision) numbers.
2. **Projection**: Map the high-precision numbers to the lower-precision set using the scaling factor.
3. **Storage**: Store the projected numbers in the reduced precision format.
For instance, converting model parameters from 32-bit precision (fp32) to 16-bit precision (fp16 or bfloat16) or even 8-bit (int8) or 4-bit precision can drastically reduce memory usage. Quantizing a 1-billion-parameter model from 32-bit to 16-bit precision can reduce the memory requirement by 50%, down to approximately 2 GB. Further reduction to 8-bit precision can lower this to just 1 GB, a 75% reduction.
#### Choosing the Right Data Type
The choice of data type for quantization depends on the specific needs of your application:
- **fp32**: Offers the highest accuracy but is memory-intensive and may exceed GPU RAM limits for large models.
- **fp16 and bfloat16**: These halve the memory footprint compared to fp32. bfloat16 is preferred over fp16 due to its ability to maintain the same dynamic range as fp32, reducing the risk of overflow.
- **fp8**: An emerging data type that further reduces memory and compute requirements, showing promise as hardware and framework support increases.
- **int8**: Commonly used for inference optimization, significantly reducing memory usage.
### Distributed Training: Scaling Horizontally Across GPUs
When a single GPU's memory is insufficient, distributing the training process across multiple GPUs is necessary. Distributed training allows for scaling the model horizontally, leveraging the combined memory and computational power of multiple GPUs.
#### Approaches to Distributed Training
1. **Data Parallelism**: Each GPU holds a complete copy of the model but processes different mini-batches of data. Gradients from each GPU are averaged and synchronized at each training step.
**Pros**: Simple to implement, suitable for models that fit within a single GPU’s memory.
**Cons**: Limited by the size of the model that can fit into a single GPU.
2. **Model Parallelism**: The model is partitioned across multiple GPUs. Each GPU processes a portion of the model, handling the corresponding part of the input data.
**Pros**: Effective for extremely large models that cannot fit into a single GPU’s memory.
**Cons**: More complex to implement, communication overhead can be significant.
3. **Pipeline Parallelism**: Combines aspects of data and model parallelism. The model is divided into stages, with each stage assigned to different GPUs. Data flows through these stages sequentially.
**Pros**: Balances the benefits of data and model parallelism, suitable for very deep models.
**Cons**: Introduces pipeline bubbles and can be complex to manage.
#### Implementing Distributed Training
To implement distributed training effectively:
1. **Framework Support**: Utilize frameworks like TensorFlow, PyTorch, or MXNet, which offer built-in support for distributed training.
2. **Efficient Communication**: Ensure efficient communication between GPUs using technologies like NCCL (NVIDIA Collective Communications Library).
3. **Load Balancing**: Balance the workload across GPUs to prevent bottlenecks.
4. **Checkpointing**: Regularly save model checkpoints to mitigate the risk of data loss during training.
### Conclusion
Combining quantization and distributed training offers a robust solution for training large-scale models within the constraints of available GPU memory. Quantization significantly reduces memory requirements, while distributed training leverages multiple GPUs to handle models that exceed the capacity of a single GPU. By effectively applying these techniques, you can optimize GPU usage, reduce training costs, and achieve scalable performance for your machine learning models.

1,897,050 | Managing and Rotating Secrets with AWS Secrets Manager | TL; DR; Securely managing secrets and credentials is crucial for maintaining the integrity... | 0 | 2024-06-24T06:30:00 | https://dev.to/dhoang1905/managing-and-rotating-secrets-with-aws-secrets-manager-eci | aws, terraform, security | ## TL; DR;
Securely managing secrets and credentials is crucial for maintaining the integrity of your applications in the cloud. AWS Secrets Manager simplifies this process by providing a centralized, secure repository for storing, managing, and rotating secrets such as database credentials, API keys, and application credentials. This article explains how to use AWS Secrets Manager, highlights its key features, and provides a practical example using Terraform to set up secret rotation with a Lambda function. You'll learn how to securely store secrets, eliminate hard-coded credentials, automate secret rotation, and enhance your application's security.
---
Maintaining the security and integrity of your apps and data in today's cloud environments depends on securely managing secrets and credentials. You can securely store, manage and rotate secrets with the aid of AWS Secrets Manager. This post will walk you through the process of safely storing managing and rotating credentials and secrets using AWS Secrets Manager. Furthermore, I will provide an example case of AWS Secrets Manager with Terraform.
## Understanding AWS Secrets Manager
AWS Secrets Manager enables you to manage, retrieve, and rotate database credentials, application credentials, OAuth tokens, API keys, and other sensitive secrets throughout their lifecycle. Many AWS services can store and use secrets directly from Secrets Manager.
By using Secrets Manager, you can enhance your security posture by eliminating the need to hard-code credentials in your application source code. Storing credentials in Secrets Manager helps prevent potential exposure to anyone who can access your application or its components. Instead of hard-coding credentials, you make a runtime call to Secrets Manager to retrieve them dynamically when needed.
### Key features :
**Secure Storage:**
- Encryption: Secrets are encrypted at rest using AWS Key Management Service (KMS) keys, ensuring that your sensitive data is protected.
- Access Control: Fine-grained access control policies can be set using AWS IAM to restrict access to secrets based on roles and permissions.
**Automatic Rotation:**
- Rotation Schedules: AWS Secrets Manager allows you to automatically rotate secrets according to a predefined schedule, helping to ensure that your secrets are regularly updated according to your security policies and without manual intervention.
- Lambda Integration: Integrate genuinely with AWS Lambda to define custom rotation logic for your secrets.
**Access Control and Auditing:**
- IAM Policies: Define who or what can access your secrets through IAM, ensuring that only authorized users and applications can retrieve sensitive data.
- Audit Logging: Integration with AWS CloudTrail provides detailed logs of secrets access, enabling you to monitor and audit sensitive data usage for compliance and security purposes.
**Secrets Management:**
- Versioning: AWS Secrets Manager supports versioning of secrets, allowing you to maintain multiple versions of a secret and revert to previous versions if necessary.
- Secret Retrieval: Retrieve secrets programmatically using AWS SDKs, CLI, or HTTP-based requests, ensuring that your applications can securely access secrets when needed.
**Integration with AWS Services:**
- Amazon RDS: Easily rotate database credentials for Amazon RDS instances with built-in support.
- Other AWS Services: Seamless integration with other AWS services like Amazon EC2, AWS Lambda, and Amazon ECS to securely manage access to secrets across your application.
## Setting Up AWS Secrets Manager with Terraform
First let's create a simple secret with two values : a username and a password :
```terraform
resource "aws_secretsmanager_secret" "credentials" {
name = "sensitive-credentials"
}
resource "aws_secretsmanager_secret_version" "example_version" {
secret_id = aws_secretsmanager_secret.credentials.id
secret_string = jsonencode({
username = "example_user"
password = "example_password"
})
}
```
Then create the lambda with its specific permissions :
```terraform
resource "aws_iam_role" "lambda_rotation_role" {
name = "lambda_rotation_role"
assume_role_policy = jsonencode({
Version = "2012-10-17"
Statement = [
{
Action = "sts:AssumeRole"
Effect = "Allow"
Principal = {
Service = "lambda.amazonaws.com"
}
}
]
})
}
resource "aws_iam_role_policy_attachment" "lambda_rotation_policy_attachment" {
role = aws_iam_role.lambda_rotation_role.name
policy_arn = aws_iam_policy.lambda_rotation_policy.arn
}
resource "aws_iam_policy" "lambda_rotation_policy" {
name = "lambda_rotation_policy"
policy = jsonencode({
Version = "2012-10-17"
Statement = [
{
Effect = "Allow"
Action = [
"secretsmanager:GetSecretValue",
"secretsmanager:PutSecretValue",
"secretsmanager:UpdateSecretVersionStage",
"secretsmanager:DescribeSecret"
]
Resource = [ aws_secretsmanager_secret.credentials.arn ]
}
]
})
}
resource "aws_lambda_function" "rotation_lambda" {
filename = "lambda_rotation.zip" # Path to your zip file
function_name = "SecretRotationFunction"
role = aws_iam_role.lambda_rotation_role.arn
handler = "rotation.lambda_handler"
runtime = "python3.8"
source_code_hash = filebase64sha256("lambda_rotation.zip")
environment {
variables = {
SECRET_ARN = aws_secretsmanager_secret.credentials.arn
}
}
}
```
With the corresponding python script that will handle the secret rotation logic depending on your need :
```python
import boto3
import json
import os
import secrets
import string
def generate_random_password(length=16):
# Define the characters to use for password generation
alphabet = string.ascii_letters + string.digits + string.punctuation
# Generate a random password
password = ''.join(secrets.choice(alphabet) for i in range(length))
return password
def lambda_handler(event, context):
# Retrieve the secret details
secretsmanager_client = boto3.client('secretsmanager')
secret_arn = os.environ['SECRET_ARN']
# Get the current secret value
current_secret_value = secretsmanager_client.get_secret_value(
SecretId=secret_arn
)
# Generate a new random password
new_password = generate_random_password()
# Update the secret with the new password
secretsmanager_client.put_secret_value(
SecretId=secret_arn,
SecretString=json.dumps({
"username": json.loads(current_secret_value['SecretString'])['username'],
"password": new_password
})
)
return {
'statusCode': 200,
'body': json.dumps('Secret rotated successfully')
}
```
And finally, configure Secret Manager to use the Lambda to rotate the secret every 30 days :
```terraform
resource "aws_secretsmanager_secret_rotation" "example_rotation" {
secret_id = aws_secretsmanager_secret.credentials.id
rotation_lambda_arn = aws_lambda_function.rotation_lambda.arn
rotation_rules {
automatically_after_days = 30
}
}
resource "aws_lambda_permission" "allow_secretsmanager" {
statement_id = "AllowSecretsManagerInvoke"
action = "lambda:InvokeFunction"
function_name = aws_lambda_function.rotation_lambda.function_name
principal = "secretsmanager.amazonaws.com"
source_arn = aws_secretsmanager_secret.credentials.arn
}
```
**Deploy it** 🚀
```bash
zip lambda_rotation.zip rotation.py
terraform init
terraform apply
```
## Test the solution
In your AWS console, go to the AWS Secret Manager page and select the secret that we just created. Click on "Retrieve secret value", you should see the inital value that we set with Terraform :
Now on the "Rotation" tab click on "Rotate secret immediately" and confirm. After retrieving the secret value another time, you should now have a fresh new generated password:
This action will now be performed each 30 days. You can change the period of rotation and even define a cron schedule expression to fit more accurately your need.

1,898,465 | A Comprehensive Guide to Interface Testing | Like any other testing, interface testing helps in thoroughly testing the software. It ensures that... | 0 | 2024-06-24T06:26:55 | https://dev.to/jamescantor38/a-comprehensive-guide-to-interface-testing-5ahm | interfacetesting, testgrid | Like any other testing, interface testing helps in thoroughly testing the software. It ensures that the end-user of the software does not face any heated issues.
No doubt it is tricky, but there is a requirement of proper planning to perform. One of the best ways to perform interface testing is to automate test cases, which produces robust and high-quality results.
## What is Interface Testing?
‘Interface testing is a type of software testing method which acts as an interacting or communicating medium between two remote software systems.’
Usually, an interface is a medium that helps two components to communicate with each other. It can be in any form like API, web design, graphics, etc.
It represents specific commands, messages, or other unique attributes. These act as a bridge between a device and its user. Thus, helping to communicate extensively. Therefore, when one tests these communication media for proper working, it is termed interface testing.
## How to do Interface Testing?
Interface testing is mainly for two primary segments. These two segments need constant care to avoid a complete breakdown of essential services. The two segments are:
- It is the common interface between the web server and the application server.
- It is the common interface between the application server and the database server
.
The scenarios mentioned above are crucial for a device to work correctly. It also helps to analyze for the user to communicate actively with the system. Hence interface testing is essential for the following reasons:
● To check and verify whether the commands provided to servers are executed in proper sequence or not.
● To check whether all the possibilities of errors can be correctly handled. The appropriate error message is returned to denote the issue.
● While some operation is ongoing, it has to thoroughly check and analyze how the outcomes are provided when general connections for a web server are reset while codes are executed.

## Some Examples of Interface Testing
:
Consider some random application in a general XML file for the input, and the output is transformed into a general JSON file. Running an interface test on this sample output is quite easy. The tester only needs the specifications carried by the XML file format and the JSON file format.
Eventually, when you have completed all the required specifications are completed, the tester can create a sample environment.
Here the input fed in is an XML file format. When the XML file format input is provided, and the output is received in a JSON file format, the tester can match the results with the required specifications.
If the match turns out to be a positive one, the interface testing process is completed successfully.
## Why Do Interface Testing?
Running regular interface tests is crucial for the health of an interface application.
- It also needs to ensure that it performs correctly while communicating between the user and the device. Here is why interface testing is important for any interface application:
- It ensures that an end-user does not face or encounter any major, minor or hindrance while using a particular software or application.
- Helps to accurately identify the central area of use or the part of the software; constantly accessed by the end-user. It also checks the user-friendliness of that part thoroughly.
- Interface testing checks all the working of the security requirements. At the same time, every piece of data or information propagates through the lines to complete the channels of communication between two working systems.
- Carried on to check whether a particular solution can deal with failures in a network that connects an application server to a specific website.
Helps catch integration errors early in the development cycle. Since interfaces connect different parts of an overall system, testing them thoroughly reveals issues with incompatible data formats, protocols, timeouts, resource contention, and other integration problems. Catching these errors early prevents cascading failures down the line.
Tests end-to-end functionality and data flows across interface connections. This builds confidence that the integrated system will work as expected when deployed.
Shifts testing left to earlier stages of development. Interface testing can begin as soon as first components are available. This provides feedback to developers early and prevents defects from piling up.
Reduces project risk and the likelihood of catastrophic failures after launch. Comprehensive interface testing across all connections between components mitigates the risk of uncaught defects that could cause system-wide outages.
## 4 Most Common Types of Interface Testing:
The various types of interface testing methods are:
● Workflow- This method ensures that the designated interface engine deals with all the standard workflow cases efficiently and adequately.
● Edge cases and unexpected values- You can test a particular test case for a date, month, and day in a reversed format.
● Performance, load, and network testing: There are two types of interface depending upon the performance: high-volume interface and low-volume interface.
You can decide this differentiation based on the engine used by the interface and the network connectivity infrastructure. Therefore, it is quite natural that any high-volume interface will need a higher load testing measure.
● Individual systems: It is a common method where you can test each system or unit of a whole application individually.
For example, in retail store software, the inventory system, administrative system, and management system should work differently and efficiently on an individual level.
## Advantages of Interface Testing:
Following are the primary advantages:
- It helps in verifying the communication between at least two or more components in detail. The application’s verification is one of the essential tasks for the ideal functionality of the application.
- Interface testing helps check the applications of the security policies for robust communication between the different components in the application.
- The testing helps in understanding the behavior of the application in case of server or network issues.
- It finds out the application areas primarily used by the users. Therefore, testing them properly.
- The testing helps in the prevention of issues way in advance before usage by the final users.
## Conclusion:
Thus, conducting interface testing regularly checks and verifies the functioning of a particular interface application and software.
These checks would prevent any breakdown or failure while the system is at work. It would also ensure that the end-user does not face any problems or difficulties when the system is at work.

Name: Orson Merrick
Place of birth: Manhattan, New York
Date of birth: June 13, 1975 (49 years old)
Place of residence: London, UK
Graduate school: New York University Stern School of Business
Education: Master of International Finance
Position: Chief Analyst and Investment Officer
Hobbies: reading, mountain climbing, swimming, golf
Character experience:
Orson Merrick was born on June 13, 1975 in Manhattan, New York City, USA.
In 1993, he graduated from The Chapin School in Manhattan, where he started his university education a year early with advanced courses. In 1994, he was admitted to Colombia University, where he studied economics, and then was admitted to New York University in 1998 for his graduate studies. He graduated magna cum laude with a master's degree in international finance from New York University's Stern School of Business.
During his studies, Orson was mentored by professor Chris Logan, and learned about the history of Wall Street in the United States through his lectures and many informal conversations. Orson was very fond of the story of the rivalry between Alexander Hamilton, the first Secretary of the Treasury, and Thomas Jefferson, the third President of the United States. As a result, he learned about the history of stocks and markets and developed a strong interest in them. During his college years, he studied macroeconomic development and microeconomics, combined with concepts from K-line analysis to integrate diversified and compound stock selection criteria. He achieved a profit rate of 64% in his first practical trading experience in the stock market, and later achieved a profit rate of 64% through his own trading in the stock market. Continuously improving his trading rules, Orson has created innovative trading ideas such as the Waltz Mechanical Manipulation Rule, the Three Point Resonance Principle, and the Institutional Trading Rule. He has also created high quality investment concepts such as the "Three Day Speculation Guidelines," "People with Reverse Thinking in the Stock Market," and "Family Investment Portfolios," which have been repeatedly regarded as classics by investors in the market.
From 2002 to 2004, he was admitted to Harvard University in the United States for further studies and obtained a certification as a Chartered Financial Analyst. In 2005, at the age of 30, Orson entered the securities investment department of Merrill Lynch, the third-largest investment bank in the United States. In the following three years, he rose from an analyst manager in the securities investment department to vice president. After years of experience in the field, Orson has developed outstanding financial analysis skills, which have cultivated his unique investment thinking. He collects a large amount of financial information and conducts comprehensive analysis on it, which serves as the basis for investment judgment.
Along the way, he met the love of his life, Brittany Megan, and started a family, which is even more important to him than his career. As Orson entered the upward phase of his career, most of the wealth he gained was used to invest in physical industries such as real estate, stock market, and medical devices in the United States, which further expanded the scope of his investments.
On September 15, 2008, the global crisis broke out and Wall Street was in chaos. Bear Stearns and Lehman Brothers went bankrupt, and Goldman Sachs and Morgan Stanley transformed themselves from investment banks to bank holding companies. Affected by the subprime crisis, Merrill Lynch suffered losses of over $50 billion and asset write downs. In September of that year, it was acquired by the second largest bank in the United States, Bank of America, for a total transaction value of approximately $44 billion to avoid facing bankruptcy. Merrill Lynch's 95 year independent corporate operation had come to an end.
Orson's portfolio also suffered its worst loss draw down that year. He resigned from his position at Merrill Lynch. At that time, Orson, like most investors, was also hit hard by the subprime crisis, making him despondent. He no longer held any hope for the financial future of him and his family. Finally, it was under the friendship and encouragement of his life mentor Chris Logan, his wife, and a group of family and friends that Orson regained hope for his financial future.
In 2009, he joined Polar Capital Holdings in the UK as Chief Analyst and Investment Officer. During this time, he has used his investment philosophy and expertise to assist clients and to develop with and protect their family/individual investment assets, enabling them to achieve their goals. He has worked on developing a methodology that combines Environmental and Social Governance (ESG) analysis with financial analysis to quantify a company's long-term potential risks and returns.
Orson Merrick's core philosophy in financial education:
1. Integrity and Ethics: Emphasize the importance of honesty, transparency, and ethics in financial decision making. The curriculum should adhere to high standards of professional ethics and behavioral norms.
2. Practice oriented: Emphasize the combination of theoretical knowledge with practice. Improve practical operational skills through case studies, market transactions, and interaction with industry experts.
3. Global perspective: To cultivate students with an international perspective and cross-cultural understanding, encourage students to pay attention to global market dynamics, and understand business practices in different markets and cultural backgrounds.
4. Innovative spirit: Encourage students to develop innovative thinking, and seek new solutions and strategies. Support students in innovative research and projects in the financial field.
5. Collaboration and communication: Advocate teamwork and exchange of technical ideas.
6. Social responsibility: Educate students to understand the impact of the financial industry on society and the environment, encourage students to participate in social responsibility projects, and cultivate a sense of responsibility and citizenship.
7. Continuous learning: Advocate the concept of lifelong learning and encourage students to keep their knowledge and skills updated through continuing education courses and seminars | orsonmerrick1 |

Apache Kafka and Apache AGE (A Graph Extension) are an amazing journey together to have Fast Real-time Graph Analysis. In this blog article, we will take you through the integration of Apache Kafka and Venus with a hands-on example on how you can use them together to build a real-time graph processing system!
## What is Apache Kafka?
A distributed streaming platform, It is a messaging system that is designed to be fast, scalable, and durable. Designed to process real-time data streams, it is often used in Big Data projects for building real-time streaming applications/data pipelines.
## What is Apache AGE?
Apache AGE (A Graph Extension) is a PostgreSQL extension that adds graph database features. It enables the use of graph query languages such as Cypher on top of relational data, allowing for complicated graph traversals and pattern matching.
## Why Integrate Kafka with AGE?
Integrating Kafka with AGE can provide the following benefits:
1. Kafka supports real-time data streaming to AGE, allowing for instantaneous graph processing.
2.Kafka's distributed architecture enables **scalable** data intake, whereas AGE offers scalable graph querying capabilities.
3. **Robust Fault Tolerance**: Kafka and PostgreSQL (with AGE) provide trustworthy data pipelines.
## Setting Up the Environment
**Prerequisites**

Integrating Kafka with AGE
```
**Step 3: Create a Kafka Consumer to Ingest Data into AGE**
We will use a simple Python script to consume messages from Kafka and insert them into a PostgreSQL database with AGE enabled.
1.Install Required Libraries:
```
pip install confluent_kafka psycopg2
```
2.Kafka Consumer Script:
```
from confluent_kafka import Consumer, KafkaException
import psycopg2
# Kafka configuration
kafka_conf = {
'bootstrap.servers': 'localhost:9092',
'group.id': 'graph-group',
'auto.offset.reset': 'earliest'
}
consumer = Consumer(kafka_conf)
# PostgreSQL configuration
conn = psycopg2.connect(
dbname="your_db",
user="your_user",
password="your_password",
host="localhost"
)
cur = conn.cursor()
# Subscribe to Kafka topic
consumer.subscribe(['real-time-graph'])
def process_message(msg):
data = msg.value().decode('utf-8')
# Insert data into PostgreSQL with AGE
cur.execute("SELECT * FROM create_vlabel('person')")
cur.execute(f"SELECT * FROM create_vertex('person', '{data}')")
conn.commit()
try:
while True:
msg = consumer.poll(timeout=1.0)
if msg is None:
continue
if msg.error():
if msg.error().code() == KafkaException._PARTITION_EOF:
continue
else:
print(msg.error())
break
process_message(msg)
except KeyboardInterrupt:
pass
finally:
consumer.close()
cur.close()
conn.close()
```
## Visualizing Graph Data
Once your data is in AGE, you can use Cypher queries to analyze and visualize your graph data. For example, to find all nodes connected to a specific node:
```
MATCH (n:person)-[r]->(m)
WHERE n.name = 'John Doe'
RETURN n, r, m;
```
You can use tools like pgAdmin or any PostgreSQL client to run these queries and visualize the results.
## Conclusion
Integrating Apache Kafka and Apache AGE enables you to create a strong real-time graph processing solution. Kafka supports real-time data ingestion, whereas AGE offers extensive graph processing capabilities. This combination is suitable for applications that require real-time insights from complicated relationships in data.
By following the procedures detailed in this blog, you may configure and begin using Kafka with AGE, providing real-time graph processing for your data-driven applications.

1,898,460 | Automating Python Function Conversion to FastAPI Endpoints | In the rapidly evolving landscape of software development, APIs (Application Programming Interfaces)... | 0 | 2024-06-24T06:24:05 | https://dev.to/harshitlyzr/automating-python-function-conversion-to-fastapi-endpoints-11ea | In the rapidly evolving landscape of software development, APIs (Application Programming Interfaces) have become the backbone of modern applications, facilitating communication between different software components. FastAPI, a modern web framework for building APIs with Python, has gained popularity due to its high performance and ease of use. However, converting existing Python functions into FastAPI endpoints can be a tedious and error-prone process, especially for developers who are new to FastAPI.
Many developers and organizations have a significant amount of legacy code written in Python functions that need to be exposed as APIs. The manual conversion of these functions into FastAPI endpoints requires a deep understanding of both the existing codebase and the FastAPI framework. This process involves several steps, including error handling, input validation, and defining the correct API routes. Manual conversion is not only time-consuming but also prone to human errors, which can lead to bugs and security vulnerabilities in the API.
Objective
The objective is to develop a tool that automates the conversion of Python functions into FastAPI endpoints. This tool should:
Accept Python Function Code: Allow users to input their Python function code directly into the tool.
Validate and Compile Code: Automatically validate and compile the input code to ensure it is error-free.
Generate FastAPI Endpoints: Convert the validated Python function code into a fully functional FastAPI endpoint, handling aspects like request validation and response formatting.
Minimize User Effort: Provide a simple and intuitive interface that minimizes the effort required by the user to perform the conversion.
Ensure Code Quality: Maintain high standards of code quality and consistency in the generated FastAPI endpoints.
Solution
Leveraging the capabilities of Streamlit for the user interface and Lyzr Automata’s AI-Agents, the proposed solution will:
Input Python Function: Provide a text area for users to input their Python function code.
Process Code with AI: Use Lyzr Automata’s AI models to validate, compile, and convert the input code into a FastAPI endpoint.
Display Results: Show the generated FastAPI endpoint code to the user for review and use.
**Setting Up the Environment**
**Imports:**
Imports necessary libraries: streamlit, libraries from lyzr_automata
```
pip install lyzr_automata streamlit
```
```
import streamlit as st
from lyzr_automata.ai_models.openai import OpenAIModel
from lyzr_automata import Agent,Task
from lyzr_automata.pipelines.linear_sync_pipeline import LinearSyncPipeline
from PIL import Image
```
**Sidebar Configuration**
We create a sidebar for user inputs, including an API key input for accessing the OpenAI GPT-4 model. This ensures that the API key remains secure.
```
api = st.sidebar.text_input("Enter our OPENAI API KEY Here", type="password")
if api:
openai_model = OpenAIModel(
api_key=api,
parameters={
"model": "gpt-4-turbo-preview",
"temperature": 0.2,
"max_tokens": 1500,
},
)
else:
st.sidebar.error("Please Enter Your OPENAI API KEY")
```
**Defining the Conversion Function**
Now, let’s define a function that uses the Lyzr Automata model to convert the Python function into a FastAPI endpoint. We’ll use an agent and a task to accomplish this:
```
def fastapi_converter(code_snippet):
python_agent = Agent(
prompt_persona="You Are Expert Python developer who is expert in building fast api",
role="Fast API Expert",
)
fastapi_task = Task(
name="fast api converter",
output_type=OutputType.TEXT,
input_type=InputType.TEXT,
model=openai_model,
agent=python_agent,
log_output=True,
instructions=f"""Your Are an Expert Python Developer. Your task is to convert the given code into Fast API.
Follow these instructions:
1. NLP check:
Compile this code.
If error:
resolve the error
return the resolved code
else:
return the entered code
Convert the code into Fast API.
2. Do not write anything apart from code.
Code: {code_snippet}
""",
)
output = LinearSyncPipeline(
name="Generate FastAPI",
completion_message="FastAPI Converted!",
tasks=[fastapi_task],
).run()
return output[0]['task_output']
```
**Output:**
```
code = st.text_area("Enter Code", height=300)
if st.button("Convert"):
solution = fastapi_converter(code)
st.markdown(solution)
```
Creates a text area for users to enter their Python code using st.text_area.
Defines a button using st.button titled "Convert".
When the button is clicked:
Calls the fastapi_converter function with the entered code.
Displays the converted FastAPI code using st.markdown.
Running the App
Finally, run the app using the following command in your terminal:
streamlit run app.py

Hello everyone! We've created a Python SDK for the Oxylabs Scraper APIs to help simplify integrating with Oxylabs's APIs.
You can find it here: https://pypi.org/project/oxylabs/
Would appreciate if Oxylabs users could try it out and give their feedback so we can start addressing it and improving the SDK.
Here's a quick start example:
```python
from oxylabs import RealtimeClient
# Set your Oxylabs API Credentials.
username = "username"
password = "password"
# Initialize the SERP Realtime client with your credentials.
c = RealtimeClient(username, password)
# Use `bing_search` as a source to scrape Bing with nike as a query.
res = c.serp.bing.scrape_search("nike")
print(res.raw)
```
It works with both the real-time and async integration methods and makes it especially easy to use the latter method which is otherwise quite tedious.
Source code is at https://github.com/oxylabs/oxylabs-sdk-python
Thank you!

- npx tailwindcss init creates a default tailwind.config.js file in your project. This file is where you will customize Tailwind’s behavior.
### Step 2: Set Up Content Paths in Configuration
Tailwind CSS needs to know where your templates are located to scan them for class names. Edit the tailwind.config.js file to include the paths to all of your HTML and JavaScript files. This step helps in removing unused styles and optimising your final CSS bundle.
```
/ tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
content: ["./src/**/*.{html,js}"],
theme: {
extend: {},
},
plugins: [],
}
```
- content: Specifies the paths to all your HTML and JavaScript files, enabling Tailwind to purge unused CSS.
- theme: Used to extend Tailwind’s default theme. Customize it according to your design requirements.
- plugins: Add any official or community-made plugins here to extend Tailwind’s core functionality.
### Step 3: Integrate Tailwind Directives into Your Main CSS File
To apply Tailwind’s styles to your project, you need to add Tailwind’s directives to your CSS. These directives act as placeholders that the CLI will replace with actual CSS.
In your project’s CSS file (e.g., src/input.css), add these lines:
```
/* src/input.css */
@tailwind base;
@tailwind components;
@tailwind utilities;
```
- @tailwind base; injects Tailwind’s foundational styles like normalize.css.
- @tailwind components; includes any custom-designed component classes.
- @tailwind utilities; applies utility classes, which are the core of Tailwind’s styling mechanism.
### Step 4: Compile Your Tailwind CSS
Now, use the Tailwind CLI to transform the directives into concrete styles based on your configuration and the classes used in your templates.
Execute this command to compile your CSS and watch for any changes:
```
npx tailwindcss -i ./src/input.css -o ./src/output.css --watch
```
- -i ./src/input.css points to the input file with your directives.
- -o ./src/output.css specifies where to save the generated CSS.
- –watch tells Tailwind to monitor the input files for changes and rebuild the CSS automatically.
### Step 5: Reference the Compiled CSS in Your HTML
The final step is to link the generated CSS file in your HTML documents. This enables you to start using Tailwind’s utility classes to style your application.
Link to the compiled CSS in your main HTML file (e.g., index.html):
```
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="./src/output.css">
</head>
<body>
<h1 class="text-3xl font-bold underline">
Hello world!
</h1>
</body>
</html>
```
You’ve now successfully installed Tailwind CSS and configured your project to use it effectively. With Tailwind’s utility-first approach, you can rapidly design and customize your UI directly within your HTML, facilitating a faster and more responsive development workflow.
## HOW TO USE TAILWIND CSS WITH REACT
Using Tailwind with React **speeds up the development by allowing you to apply utility classes directly within your React components**. Below I’ll show you some examples of how to apply these classes to manage layout, typography, and colour.
### Layout
Tailwind’s utility classes make it easy to define your component’s structure. Here’s an example of setting up a simple centered layout in a React component:
```
<div className="w-full flex justify-center items-center h-screen" />
```
- w-full: Sets the width of the element to 100% of its parent container.
- flex: Applies display: flex; making it a flex container.
- justify-center: Centers the content along the horizontal axis using justify-content: center;.
- items-center: Centers the content along the vertical axis using align-items: center;.
- h-screen: Sets the height of the element to 100vh (viewport height), making it take the full screen height.
### Typography
Tailwind provides utilities for typography to control the font weight, size, and more directly within your JSX. Here is how you can style text:
```
<h1 className="font-bold text-xl">Hello CodeSandbox</h1>
```
- font-bold: Applies a font weight of 700, making the text bold.
- text-xl: Sets the font size to 1.25rem with a line height of 1.75rem.
### Colours
Tailwind’s colour utilities allow you to apply colour styles easily. Below is how you can use these classes to add colour to backgrounds and text:
```
<div className="bg-red-600 text-blue-700">
<h1 className="font-bold text-xl">Hello CodeSandbox</h1>
<h2>Start editing to see some magic happen!</h2>
</div>
```
- .text-blue-700: Applies a text color (blue-700 is a specific shade of blue).
```
.text-blue-700 {
--tw-text-opacity: 1;
color: rgb(29 78 216 / var(--tw-text-opacity));
}
```
- .bg-red-600: Applies a background colour using Tailwind’s colour scale (red-600 corresponds to a specific shade of red).
```
.bg-red-600 {
--tw-bg-opacity: 1;
background-color: rgb(220 38 38 / var(--tw-bg-opacity));
}
```
### Colours with Arbitrary Values
Tailwind CSS supports using arbitrary values for colours through the bracket notation ([]). This is useful if you need to use a colour that isn’t in the default palette:
```
<h2 className="text-[#fff]">Start editing to see some magic happen!</h2>
```
- .text-[#fff]: Sets the text color to white using Tailwind’s arbitrary value syntax.
```
.text-\[\#fff\] {
--tw-text-opacity: 1;
color: rgb(255 255 255 / var(--tw-text-opacity));
}
```
Using Tailwind CSS with React **improves the development workflow by enabling component-based styling directly within JSX**. It eliminates the need for separate CSS files, allowing developers to **define styles using utility classes** for layout, typography, and colour.
For example, creating a full-screen, centre-aligned layout is straightforward with classes like w-full, flex, justify-centre, items-center, and h-screen. Similarly, setting typography and colour can be done in-line, such as using text-xl and font-bold for font sizing and weight, and bg-red-600 or text-blue-700 for colors. It streamlines the styling process, making it faster and more intuitive.
## ADVANCED IMPLEMENTATION
Here’s how to apply advanced Tailwind CSS techniques within React projects, improving component-based styling and overall user experience.
### How to Center a Div Using Tailwind in React
To center a div using Tailwind CSS, apply a combination of utility classes that specify full width, flexbox display, center alignment, and full viewport height. Here’s the implementation:
```
import React from "react";
import ReactDOM from "react-dom/client";
import App from "./App";
const rootElement = document.getElementById("root")!;
const root = ReactDOM.createRoot(rootElement);
root.render(
<React.StrictMode>
<App />
</React.StrictMode>
);
```
### Practical examples of layout control
For more complex layouts, Tailwind’s grid system and spacing utilities offer fine control:
```
import React from "react";
import ReactDOM from "react-dom/client";
import App from "./App";
const rootElement = document.getElementById("root")!;
const root = ReactDOM.createRoot(rootElement);
root.render(
<React.StrictMode>
<App />
</React.StrictMode>
);
```
### Implementing UX Design in Tailwind CSS
#### Responsive Design and Media Queries
Tailwind’s utility-first approach includes responsive design features that use mobile-first breakpoints:
- Breakpoint Prefix: Shorthand used in class names to control when a style applies.
- Minimum Width: The screen width at which these styles become active.
- CSS: The actual CSS media query used.
For practical application, you can tailor your components to respond to different screen sizes using these breakpoints. For example:
```
<div className="inner bg-green-100 grid grid-cols-1 md:grid-cols-[20rem_1fr] gap-4">
…
</div>
```
- `grid-cols-1` will be applied on mobile and `md:grid-cols-[20rem_1fr]` from 768px
If you need to make some changes on a breakpoint that is not preset in a table above you have two options:
- You can use arbitrary value: min-[328px]:text-blue-200 max-[580px]:text-center
- You can extend tailwind config:
```
/** @type {import('tailwindcss').Config} */
module.exports = {
theme: {
…
extend: {
screens: {
'custom': '328px',
// => @media (min-width: 328px) { ... }
},
}
}
}
```
You can also get rid of the default breakpoints and add only the ones that you need:
```
/** @type {import('tailwindcss').Config} */
module.exports = {
theme: {
screens: {
small: '400px',
medium: '850px',
large: '1024px',
},
…
}
}
```
Then instead of writing `sm:text-center` you would use `small:text-center`
### Extending Tailwind with Custom Configurations
Tailwind CSS is highly customizable, allowing you to tailor the framework to meet the specific design needs of your project. This is particularly useful when your design system or style guide includes specific colors, spacing, breakpoints, or typography that differ from Tailwind’s defaults.
#### Understanding the Tailwind Configuration
The Tailwind configuration file (tailwind.config.js) is where you define your customizations. The theme section of this configuration file allows you to specify how your design tokens such as colors, spacing, and typography should be adjusted or extended.
#### Overriding vs. Extending:
Overriding the default configuration means replacing the default settings entirely with your custom settings.
Extending the default configuration means adding to or modifying the existing settings without removing the default settings.
Extending the Theme
To extend the existing theme without losing the default configurations, you use the extend key inside the theme object. This approach is preferred when you want to add additional utilities while keeping all the original Tailwind settings.
Example:
```
/** @type {import('tailwindcss').Config} */
module.exports = {
theme: {
extend: {
colors: {
transparent: 'transparent',
black: '#000',
white: '#fff',
gray: {
100: '#f7fafc',
// ...
900: '#1a202c',
},
// ...
}
}
}
}
```
- theme: { extend: { … } }: This structure tells Tailwind that you are adding to the existing theme rather than replacing it.
- colors:: Inside the extended block, we define our custom colors. This object specifies the colour name as the key (e.g., grey, black) and the corresponding colour value.
- transparent, black, and white are defined with their respective CSS colour values.
- gray is an object itself, which allows you to set a spectrum of shades from 100 (light grey) to 900 (dark grey).
- By placing these inside extend, all other colour utilities [provided by Tailwind](https://tailwindcss.com/docs/theme) are preserved, and these new colours are added to the palette.
#### Overriding the Entire Configuration
This approach involves setting your configurations directly under the theme section without extend, which replaces the entire default configuration with your custom settings.
Example:
```
/** @type {import('tailwindcss').Config} */
module.exports = {
theme: {
colors: {
transparent: 'transparent',
black: '#000',
white: '#fff',
gray: {
100: '#f7fafc',
// ...
900: '#1a202c',
},
// ...
}
}
}
```
- Direct Definition: Here, the colours are defined directly under the theme.colours property without using extend.
- Replaces Defaults: This approach replaces all of Tailwind’s default colour utilities with your custom definitions. The default colours will no longer be available unless you redefine them here.
## TIPS FOR USING TAILWIND TO ENHANCE USER EXPERIENCE.
- dark mode – you can use the `dark:` selector to apply some styles when dark mode is on
- rems as the base unit – by default, tailwind is using `rem` as a base unit for all of the spacings, etc. Thanks to this the page will scale properly when different font size is set on the root element
- pseudo-classes like hover, etc as selectors – if you want to apply a hover effect, or add something on focus, etc., you can use `hover:`, `focus:`, etc. selectors. There are also some custom ones, like `peer` which you can use to style a checkbox, or `group` which can be used to apply some styles on the element inside a group when the wrapper is hovered, etc.
## CONCLUSION
Using Tailwind CSS simplifies the styling process and boosts the overall development workflow by **allowing for component-based styling directly within JSX**. It eliminates the need for separate CSS files and enables rapid prototyping and customization of user interfaces. By following the steps and techniques outlined in this guide, you c**an effectively use Tailwind CSS to create responsive, accessible, and visually appealing applications that adhere to your design specifications**.

1,898,445 | How to Add Syntax Highlighting to Next.js app router with PrismJS ( Server + Client ) Components | How to Add Syntax Highlighting to Next.js app router with PrismJS ( Server + Client )... | 0 | 2024-06-24T06:12:58 | https://dev.to/sh20raj/how-to-add-syntax-highlighting-to-nextjs-app-router-with-prismjs-server-client-components-40mm | nextjs, javascript | # How to Add Syntax Highlighting to Next.js app router with PrismJS ( Server + Client ) Components
Adding syntax highlighting to your Next.js project can greatly enhance the readability and visual appeal of your code snippets. This guide will walk you through the process of integrating PrismJS into your Next.js application to achieve runtime syntax highlighting.
If you prefer to add syntax highlighting at build time, refer to the guide on [How To Add Syntax Highlighting To Markdown With Next.js and Rehype Prism](https://nextjs.org/learn/basics/markdown-and-mdx/markdown#adding-syntax-highlighting).
## Step 1: Initialize Your Next.js Project
First, create a new Next.js project by running the following command:
```bash
npx create-next-app@latest
```
## Step 2: Install PrismJS
Next, install PrismJS along with its TypeScript type definitions:
```bash
npm install prismjs
npm i --save-dev @types/prismjs
```
## Step 3: Create a PrismLoader Component
Create a new file for the PrismLoader component. This component will handle loading PrismJS and applying the syntax highlighting.
Create a new file at `/components/prism-loader.tsx` with the following content:
```typescript
"use client";
import { useEffect } from "react";
import Prism from "prismjs";
import "prismjs/themes/prism-okaidia.css";
import "prismjs/components/prism-typescript";
export default function PrismLoader() {
useEffect(() => {
Prism.highlightAll();
}, []);
return <div className="hidden"></div>;
}
```
Feel free to choose a different theme or add additional languages by importing the corresponding components from PrismJS.
## Step 4: Use the PrismLoader in Your Pages
Finally, include the PrismLoader component in any page where you want to enable syntax highlighting. Here is an example of how to use it in the main page of your application.
Create or modify the file at `/app/page.tsx`:
```typescript
import PrismLoader from "@/components/prism-loader";
export default function Home() {
return (
<div>
<pre className="language-js">
<code className="language-js">console.log("hello world")</code>
</pre>
<pre className="language-ts">
<code className="language-ts">console.log("hello world")</code>
</pre>
<PrismLoader />
</div>
);
}
```
### Important Note
JavaScript syntax highlighting is supported by default. For other languages, such as TypeScript, you will need to import the specific language components, as shown in the [PrismLoader component example](https://www.fullstackbook.com/blog/how-to-add-syntax-highlighting-to-nextjs-with-prismjs).
By following these steps, you can easily add dynamic syntax highlighting to your Next.js project using PrismJS. This setup allows for a clean and visually appealing presentation of your code snippets, enhancing the overall user experience. | sh20raj |
1,898,416 | From Contributor to Maintainer: Lessons from Open Source Software | Since I started focusing on contributions to open-source projects a few years ago, I’ve opened and... | 0 | 2024-06-24T06:12:54 | https://dev.to/patinthehat/from-contributor-to-maintainer-lessons-from-open-source-software-3mog | opensource, webdev, beginners, programming | Since I started focusing on contributions to open-source projects a few years ago, I’ve opened and had merged hundreds of Pull Requests. This article outlines some of the lessons I've learned from contributing to, authoring, and maintaining popular open-source projects.
## Creating Open Source Projects
*Avoid creating projects that you cannot or will not maintain.* Open-source projects require ongoing attention to address issues, update dependencies, and incorporate new features. If you do not have the capacity or commitment to maintain a project, it is better not to release it to the public.
*Your code should be easily understood and be maintainable by others.* Clear documentation, consistent coding standards, and well-organized codebases are essential when introducing an open source project. This not only facilitates collaboration but also ensures that others can step in to help with maintenance or contribute new features.
*Avoid creating packages that are too specific.* The more generalized and flexible your project, the broader its appeal and utility to the community. By focusing on creating versatile and widely applicable projects, you can attract a larger base of users and contributors.
*Automate everything.* To streamline the maintenance and management of your projects, use of GitHub workflows and features like Dependabot whenever you can. Automating processes such as merging Dependabot PRs, running test suites, marking issues as stale, and updating the changelog can significantly reduce the manual workload. These tools ensure that your project remains up-to-date and stable without constant manual intervention.
## Contributing to Open Source Projects
*Target projects that you use frequently.* Familiarity with the functionality and nuances of it puts you in a position to provide meaningful features or fixes. Whether squashing bugs that you’ve discovered or implementing features you have use cases for, your contributions will likely address needs that others have also encountered.
*Your contributions are public and are a reflection on you as an engineer.* Remember that potential employers may look at your previous work. It's important to think carefully about the quality and thoroughness of your contributions; each pull request you make is a demonstration of your abilities and your understanding of software development. By consistently contributing well-structured, tested, and documented code, you not only support the projects you care about but also build a strong professional reputation that can open doors to future opportunities.
*Open thoughtful pull requests.* The clarity and thoroughness of your PR descriptions make a significant difference in whether or not it gets merged quickly, slowly, or at all. Start by summarizing what the pull request does in a few sentences, then drill down into the important points below. This approach not only helps maintainers understand the scope and purpose of your changes quickly, but also facilitates a timely, smooth review process.
*Keep your pull requests small and focused.* Each PR should add a single feature or fix a single bug. This streamlines the review process for maintainers, enabling them to review and merge your code more quickly. Likewise, it’s also easier to address any requested changes promptly. A small, well-defined PR is less likely to introduce unintended side effects and is generally easier to test and validate.
*Include unit tests.* Responsible maintainers will rarely merge code without appropriate tests, as they help ensure that new changes do not break existing functionality. By including unit tests with your Pull Request, you’re respecting the maintainers' time and reduce the back-and-forth that can occur when tests are missing. Even if your PR seems trivial or is already covered by existing tests, demonstrating that you've thought about testing can expedite the merge process and reflect positively on your contributions.
*Update documentation when you make API changes.* If the project you’re contributing to has existing documentation, remember that someone took the time to write it; respect this effort on their part and make sure you update it accordingly, including using a similar tone and style. This ensures that other developers can understand and effectively use the new or modified features you have implemented. Neglecting this step can lead to confusion, undermining the usability and reliability of the project.
*Respect the time and effort of maintainers and contributors.* You’re a user of the project and have benefited from the time and effort of others. Acknowledge the hard work and dedication when you can. Demonstrating appreciation and respect allows you to receive it in return. Always be considerate and courteous.
*Respect existing code and writing styles.* Remember that this isn’t your project - it’s someone’s, though, and their preferences matter. Whether it’s two spaces for indentation instead of four (or even - *gasp* - tabs), or the writing style of the documentation, show the original author the respect of using their style preferences.
## Maintaining Open Source Projects
*It’s a privilege, not a right.* Being a maintainer and having the ability to triage issues, review and merge Pull Requests and release new versions is a privilege, not a right. This role comes with significant responsibility and trust, and should be approached seriously. Your actions as a maintainer can directly impact the quality and reliability of a project; they will also affect the experience of the project’s users. Likewise, your actions can impact the reputation of others, such as the original project author. Be mindful of this.
*Get input from others.* When uncertain about how to address an issue or handle a pull request, don’t hesitate to seek input from other maintainers. Collaboration and communication are key to making well-informed decisions that benefit the project and its community. Leveraging the collective knowledge and experience of others helps ensure that the best possible solutions are used.
*Be appreciative.* A simple thank you to a contributor or author of a bug report can go a long way. Recognizing the efforts of others not only strengthens open source community but also motivates continued contributions and engagement in the project.

Quality improvement in wood veneers, adhesives, and films had been a continuous build-up to break through for better reliability and performance. New technologies are also developed to make the production process more eco-friendly and efficient. For example, some producers have started using sustainable and renewable sources of wood to lessen their impact on the environment. Others use automated methods and robotics to increase the uniformity of cuts and assembly. All these developments have resulted in much more uniform film-faced plywood sheets that are vested with the same attributes general, consistent in dimension, precise, and faithful to the Industry Standards.
Safety in Film Faced Plywood
Construction sites are among the most hazardous kinds of workplaces in the world; they are followed closely by the industry related to their materials supply. Safety is, therefore, their concern first film faced plywood can only contribute to its achievement. This membrane or film prevents moisture and chemicals from entering the wood to cause decay or to ignite fire. It also helps in reducing accidents by slipping, tripping, or falling on the ply surface when it is wet. Other prominent feature of waterproof laminated plywood is its fire-resistance property. It can hold temperature high flame for a longer time compared to other materials so that workers have enough time to evacuate and suppress the fire. Moreover, film-faced plywood can easily be handled and installed, and at some point, reduces the possibility of accidents or injuries with the help of proper tools and equipment.
Use of Film Faced Plywood
The variety of uses of film-faced plywood in the sector of structural uses includes huge range for formwork, flooring, roofing, walls, and partitions. It finds its place in both residential and buildings that are commercial, as well as in civil engineering projects like bridges, tunnels, dams, and ports. The fact that film-faced plywood exists means versatility, flexibility, and customization in design and construction. This basically means that it can be cut at will according to the shape or size of the structure, shaped, drilled, and screwed. Apart from that, it can also be recycled or reused after its useful life. Less cost and waste are produced.
How to Use Ffilm Faced Plywood
For the proper using of faced plywood, it is very necessary to follow the instructions and standards of the manufacturer. It needs to be stored in a dry, cool, and ventilated area so that buildup moisture does not cause warping of the ply. It should, therefore, be handled with care and lifted with proper equipment or apparatus to prohibit it from bending or breaking. Cutting of ply shall be done with sharp and clean tools to attain a precise and edge smooth. Durable and sealants being waterproof, therefore, be used to seal off ply joints and seams to protect them from leaking and cracking. Also, it is necessary that the ply edges and corners should be well covered with appropriate coverings at the time of transit and installation.
Service and Quality of Film Faced Plyboard
The service quality and quality of film faced plywood would depend upon the reliability and credibility of the manufacturer and that of the supplier. It is desirable to choose a continuing company that has established a record of consistency in delivering quality film-faced plywood. Secondly, the company should have an ability to render good customer support, technical support, and warranty to their products. Checking for thickness, weight, and strength will help to get an idea about the quality of the ply. Additionally, the laminated marine plywood surface should be checked for any damage or defect before use. One can assure and ensure the quality and safety of the project with a reputable and maker-reliable supplier.

One of my favorite things about software development is that you can never grow bored or know *too much*. There is always something that pulls me in deeper and deeper and lately that has been [Elixir](https://hexdocs.pm/elixir/1.17.1/Kernel.html). I have written two other blogs going over the strengths of Elixir and how [Erlang](https://www.erlang.org/doc/system/getting_started.html)’s Virtual Machine(The BEAM) works well with Elixir. Elixir is made up of six applications and I’m continuing this journey with a breakdown of what Elixir is and it's three libraries.
## What is Elixir?
A dynamic, functional programming language designed for building scalable, maintainable applications, leveraging The BEAM, which is known for its fault-tolerant, concurrent, and low latency systems. Needless to say, it's a go-to choice for a large range of applications that aim to benefit from its productive tooling and extensible design.
### Web Development
due to it being a powerful tool for building web applications, especially ones such as chat applications, online games, applications that require live updates, and other real-time features.
### Distributed
Elixir runs on Erlang’s virtual machine, which was specifically designed for building not only fault-tolerant systems but to also be distributed, which is perfect for applications that require distribution across multiple nodes
### Concurrency
First-class support for concurrency making it a excel with applications that require high levels of concurrency like mulit-user applications or applications with high simultaneous connections.
### Embedded Systems
Can be used to write firmware for devices and its concurrency model and fault-tolerance fits in nicely with this domain.
### Data Processing
Handles large volumes of data and concurrency support making it solid for data processing tasks.
### Telecommunications
Elixir is a descendant of Erlang, which was originally designed for telecommunication systems, making it fit in naturally with these applications/systems.
### Blockchain
Continuing on the scalability and fault-tolerance, Elixir is also used for developing blockchain technologies.
## Elixir's Standard Library
The standard library in Elixir provides a set of modules and functions that are available out of the box for Elixir developers. It’s loaded with a wide range of functionalities that aid in alleviating common programming tasks.
<u>Enum:</u> Provides a set of algorithms that enumerate over enumerables based on the Enumerable protocol.
`map`, `reduce`, and `filter`
<u>String:</u> Provides functions for working with strings, like string manipulation, in Elixir.
`length`, `replace`, `split`
<u>List:</u> This module provides functions for working with lists.
`delete`, `flatten`, `zip`
<u>Map:</u> This module provides functions for working with maps.
`get`, `put`, `keys`
<u>IO:</u> This module provides functions for input/output operations.
`puts`, `gets`, `inspect`
<u>File:</u> This module provides functions for working with files.
`read`, `write`, `ls`
<u>Process:</u> This module provides functions for working with processes.
`send`, `receive`, `alive?`
<u>GenServer</u> (Generic Server Process): This module abstracts client-server interactions, making the creation of Elixir servers easier by automatically implementing a standard set of interface functions, including tracing and error reporting. With that part of the load taken care of all that is required from the developers is to implement the functionality they desire. Neat.
<u>Agent:</u> This module provides a basic server implementation that allows state to be retrieved and updated.
<u>Task:</u> This module makes running functions asynchronously and retrieving their results easy.
These modules and their functions form the backbone of many Elixir applications, which provide crucial functionalities for tasks like data manipulation, concurrent programming, file I/O, and more.
## EEx: Elixir's Templating Library
Embedded Elixir(EEx) is a templating library, but still a part of the standard library. In *Web Development* it’s often used to generate dynamic HTML content allowing you to embed Elixir code in the HTML templates to create parts of the page according to data dynamically. You can generate dynamic HTML content and Elixir code dynamically, which is handy for those metaprogramming moments. Configuration files can also be generated dynamically based on either environment variables or conditions.
Here's a basic example of how EEx is used in an Elixir application:
```elixir
# Define a template with placeholders
template = "Hello, <%= name %>!"
# Use EEx to evaluate the template with given bindings
message = EEx.eval_string(template, [name: "World"])
# Outputs: Hello, World!
IO.puts message
```
Here, `<%= name %>` is a placeholder with embedded Elixir code. When `EEx.eval_string` is called, the placeholder is then replaced with the value of _name_ from the given bindings.
## ExUnit: Elixir's Unit Test Library
ExUnit is Elixir's built-in testing framework which provides the ability to write unit tests and various features for teardown of tests**,** setup, and assertions. Testing is essential in software development for multiple reasons. Including correctness to ensure your code behaves as expected. Prevents regression by making sure, after modifying your code, you don’t break functionality that already exists. Aids in the design of your software, in turn helping you write more maintainable, modular code. And possibly the most important, in my opinion, is that it serves as documentation, showing those that look at your code, how your code is suppose to work.
```elixir
defmodule MyApp.CalculatorTest do
use ExUnit.Case
test "add/2 returns the sum of its arguments" do
assert MyApp.Calculator.add(1, 2) == 3
end
end
```
We have our test module `MyApp.CalculatorTest` that uses `ExUnit.Case`. Inside, we define our test with the test macro. The test checks that the add/2 function of the `MyApp.Calculator` module returns the correct sum. To run the tests, you would typically use the *mix test command* in your terminal.
```elixir
mix test
```
This will run all test files in the project’s test directory. This also allows you to specify individual test files or directories to run a subset of your tests, for example:
```elixir
mix test test/my_app/calculator_test.exs
```
This will only run the tests defined in `calculator_test.exs`.
In conclusion, I'd like to say the benefits you gain when using Elixir, and all it has to offer, is fantastic. It makes me excited to keep working with it and learning so much more. I hope you learned as much as I did! | cody-daigle | |

These... | 0 | 2024-06-24T06:02:55 | https://dev.to/kala12/what-are-the-risks-involved-in-meme-coin-development-4k4e | Memecoins like Dogecoin and Shiba Inu have become very popular in the cryptocurrency world. These digital currencies often start out as jokes or internet memes, but they can quickly become serious investments. However, there are significant risks involved in developing and investing in mints. Here are ten key points to consider:
**Lack of intrinsic value
**Memecoins generally have no intrinsic value or utility. Unlike traditional cryptocurrencies such as Bitcoin, which aims to be a decentralized currency, or Ethereum, which supports smart contracts, meme-coins often do not solve any real-world problems. Their value is driven primarily by community hype and social media trends, making them highly speculative.
**High Volatility
**Memecoin prices can fluctuate wildly in a short period of time. These fluctuations are often caused by social media buzz, celebrity endorsements or online communities. While this volatility can lead to significant profits, it can also lead to large losses just as quickly.
**Scams and Fraud
**The hype around meme-coins is attracting scammers. There have been many cases where developers created a meme-coin, promoted it heavily, and then disappeared in a so-called "carpet" with investors' money. Due diligence is crucial, but in the cryptocurrency space, it's often difficult to distinguish legitimate projects from fraudulent ones.
**Regulatory Risks
**Cryptocurrencies are increasingly scrutinized by governments and regulators around the world. Memecoins may be subject to stricter regulations due to their speculative nature and interaction with online communities. New laws or regulations may affect their legality, marketability and overall value.
**Lack of Transparency
**Many cryptocurrency projects lack transparency about the development team, business plan or technical details. Such transparency makes it difficult for investors to make informed decisions. The anonymity of developers can be a red flag indicating potential risks.
**Security Vulnerabilities
**Memecoins, like all cryptocurrencies, are vulnerable to hacking and security breaches. If the underlying technology is not sustainable, it can lead to significant financial losses for investors. Smart contracting mistakes, inadequate controls, and poor security practices can increase vulnerabilities.
**Market Manipulation
**The meme coin market is prone to manipulation by large owners, also known as "docks". These individuals or groups can buy large amounts of meme-coins to increase their price and then sell their holdings, causing the price to drop. This pump and dump system can destroy small investors.
**Community Dependency
**The success of a native coin often depends on the strength and activity of its community. If the community loses interest or moves to another proprietary coin, the value of the coin can drop dramatically. This reliance on community sentiment makes meme coins particularly volatile.
**Lack of development and innovation
**Many meme-coins started out as simple copies of other cryptocurrencies with minor modifications. Without a dedicated team to update and improve the project, these coins can quickly become obsolete. Lack of continuous development can lead to stagnation and decline in value over time.
**Investment speculation
**Memecoins are primarily based on speculation. Investors buy these coins not because they believe in the project or its technology, but because they want to sell them at a higher price. This speculative nature makes mine coins more of a gamble than a sound investment strategy.
**Conclusion
**Although meme-coins can offer significant returns and a fun investment opportunity, they have significant risks. Their lack of fundamental value, high volatility and susceptibility to fraud and market manipulation make them risky. In addition, potential disadvantages are compounded by regulatory uncertainty and information security vulnerabilities.

In the previous posts, we discussed how you can run your first Docker container by pulling pre-built Docker images from Docker Hub. While it is useful to get pre-built Docker images from Docker Hub, we can't only rely on them. This is important for running our applications on Docker by installing new packages and customizing the settings of the pre-built Docker images.
This will be done using a text file called a **Dockerfile**. This file consists of commands that can be executed by Docker to create a docker image. Docker images are created from a **Dockerfile** using the `docker build` or `docker image build` command.
A Docker image consists of multiple layers, each layer representing commands provided in the **Dockerfile**. These read-only layers are stacked on top on one another to create the final Docker image. Docker images can be stored in a Docker **registry**, such as **Docker Hub**, which stores and distributes Docker images.
A Docker **container** is a running instance of the Docker **image**. One or more Docker containers can be created from a single Docker image using the `docker run` or `docker container run` command. Once a Docker container is created from an image, a new writable layer will be added on top of the read-only layers from the image.
There can be one or more read-only layers that make up a Docker image. These read-only layers are generated for each command in the **Dockerfile** during the Docker image building process. Once the container is created, a new read-write layer (known as the **Container layer**) will be added on top of the image layers and will host all changes made on the running container.
## What is a Dockerfile?
A **Dockerfile** is a text file that contains instructions on how to create a Docker image. These commands are known as **directives**. A **Dockerfile** is a way of creating a custom Docker image based on our requirements.
The format of a **Dockerfile** is as follows:
```dockerfile
# This is a comment
DIRECTIVE argument
```
A **Dockerfile** can contain multiple lines of comments and directives. These lines will be executed in order by the **Docker Engine** while building the Docker image. A Dockerfile can also contain comments.
All statements starting with the `#` symbol are treated as **comments**. Currently, Dockerfiles only support single-line comments.
Instructions within a **Dockerfile** are **case-insensitive**. Even though the **DIRECTIVE** is case-insensitive, it is considered a best practice to write all directives in uppercase to distinguish them from arguments.
## Common Dockerfile Directives
A directive is a command that is used to create a Docker image. In this section we are going to discuss the following five basic **Dockerfile** directives:
- The **FROM** directive.
- The **LABEL** directive.
- The **RUN** directive.
- The **CMD** directive.
- The **ENTRYPOINT** directive.
### The FROM Directive
A **Dockerfile** generally starts with a **FROM** directive. This is used to specify the parent image of our custom Docker image. The parent image is our starting points. All the customization that we do will be applied on top of the parent image. The parent image can be an image from Docker Hub, such as Ubuntu, or Nginx. The **FROM** directive takes a valid image name and a tag as arguments. If the tag is not specified, the **latest** tag will be used.
A **FROM** directive has the following format:
```dockerfile
FROM <image>:<tag>
```
The following **FROM** directive, uses the **ubuntu** parent image, with the **20.04** tag:
```dockerfile
FROM ubuntu:20.04
```
We can also use a special base image if we need to build a Docker image from scratch. The base image, known as the **scratch** image, is an empty image mostly used to build other parent images.
In the following **FROM** directive, we are going to use the **scratch** image to build a custom Docker image from scratch:
```dockerfile
FROM scratch
```
### The LABEL Directive
A **LABEL** is a key-value pair that can be used to add metadata to a Docker image. These labels can be used to organize the Docker images properly. Usually this includes the name of the author, or the version of the **Dockerfile**.
A **LABEL** directive has the following format:
```dockerfile
LABEL <key>=<value>
```
A Dockerfile can have multiple labels:
```dockerfile
LABEL maintainer=somerandomguy@somerandomdomain.com
LABEL version=1.0
LABEL environment=dev
```
Or you can write it as an one liner separated by spaces:
```dockerfile
LABEL maintainer=somerandomguy@somerandomdomain.com version=1.0 environment=dev
```
I prefer one **LABEL** directive per key-value pair, but each to their own I guess.
Labels can be viewed using the `docker image inspect` command:
```powershell
docker image inspect ubuntu:latest
```
```
...
"Labels": {
"org.opencontainers.image.ref.name": "ubuntu",
"org.opencontainers.image.version": "24.04"
}
...
```
### The RUN Directive
The **RUN** directive is used to execute commands during the image build time. This will create a new layer on top of the existing layer, execute the specified command, and commit the results to the newly created layer. The **RUN** directive can be used to install the required packages, create users and groups, and so on.
The **RUN** directive takes the following format:
```dockerfile
RUN <command>
```
**`<command>`** specifies the shell command you want to execute as part of the image build process. A **Dockerfile** can have multiple **RUN** directives adhering to the preceding format.
Below, we are running three commands on top of the parent image.
The **apt-get update** command will update the list of available packages and their versions, but it does not install or upgrade any packages. It ensures that the package manager has the latest information about available software.
The **apt-get upgrade** command actually installs the newest versions of all packages currently installed on the system from the sources enumerated in the sources list. New packages will be installed if required. It will not remove any packages.
The **apt-get install nginx -y** will install the `nginx` package, a high-performance web server and a reverse proxy server. The `-y` flag automatically answers "yes" to any prompts, ensuring that the installation proceeds without user intervention.
```dockerfile
RUN apt-get update
RUN apt-get upgrade
RUN apt-get install nginx -y
```
Alternatively, you can add multiple shell commands to a single **RUN** directive by separating them with the `&&` symbol. In the following example, we are going to use the same commands, but this time in a single **RUN** directive, separated by the `&&` symbol:
```dockerfile
RUN apt-get update && apt-get upgrade && apt-get install nginx -y
```
### The CMD Directive
A Docker container is generally expected to run one process. A **CMD** directive is used to provide this default initialization command that will be executed when a container is created from the Docker image. A **Dockerfile** can execute only one **CMD** directive. If you add multiple **CMD** directives in your **Dockerfile**, Docker will execute only the last one.
The **CMD** directive has the following format:
```dockerfile
CMD ["executable", "param1", "param2", "param3", ...]
```
For example, we can use the following command to echo *"Hello World"* as the output of a Docker container:
```dockerfile
CMD ["echo", "Hello World"]
```
The command will produce the following output, when we run it using the `docker container run <image> command`
```powershell
docker container run hello-world-image
Hello world
```
However, if we send any command line arguments with `docker container run <image>`, these arguments will override the **CMD** command we defined.
```powershell
docker container run hello-world-image echo "Hello Docker"
Hello Docker
```
#### So, what is the difference between RUN and CMD?
Both the **RUN** and **CMD** directives can be used to execute a shell command. The main difference between the two is that the command provided with the **RUN** directive will be executed during the image build process, while the command provided with the **CMD** directive will be executed once a container is launched from the built image.
Another notable difference is that there can be multiple **RUN** directives in a **Dockerfile**, but there can be only a single **CMD** directive. If there are multiple **CMD** directives, only the last one will be executed.
### The ENTRYPOINT Directive
Similar to the **CMD** directive, the **ENTRYPOINT** directive can also be used to provide a default initialization command that will be executed when a container is created. The difference between **CMD** and **ENTRYPOINT**, is that the **ENTRYPOINT** command cannot be overridden using command line parameters sent by the `docker container run` command.
You can override the **ENTRYPOINT** directive using the `--entrypoint` flag, with the `docker container run`.
The **ENTRYPOINT** directive has the following format:
```dockerfile
ENTRYPOINT ["executable", "param1", "param2", "param3", ...]
```
When both **ENTRYPOINT** and **CMD** are used together in a Dockerfile, the **CMD** directive provides additional arguments to the **ENTRYPOINT** executable. This combination allows for a more flexible and modular setup.
For example:
```dockerfile
ENTRYPOINT ["echo", "Hello"]
CMD ["World"]
```
The output of the `echo` command will differ based on how we execute the `docker container run` command.
If we launch the Docker image without any additional parameters, it will output the message **Hello World**
```powershell
docker run test-image
Hello World
```
But if we provide a command line parameter, the message will change:
```powershell
docker container run test-image "Docker"
Hello Docker
```
## Creating our First Dockerfile
We are going to create a Docker image that, when run, prints any arguments passed to it preceded by the text **"You are reading "** If no arguments are provided, it should print **"You are reading Awesome Posts on dev.to"**.
First lets create a new directory named **test-docker-image** using the `mkdir` command. This directory will be the **context** for our Docker image. **Context** is the directory that contains all the files needed to build the image:
```powershell
mkdir test-docker-image
```
---
Now, navigate to the newly created directory:
```powershell
cd test-docker-image
```
---
Within the **test-docker-image** directory, create a file named **Dockerfile**. I am going to use VS Code but feel free to use whatever editor you feel comfortable with.
```powershell
code Dockerfile
```
---
Let's build the contents of our **Dockerfile**. I will add comments and explain every step as we create the **Dockerfile**. However, if you prefer to copy the entire content (though I recommend against it), the final Dockerfile will be provided below.
We'll start with the **FROM** directive to specify our base image. We are going to use the **Alpine** Linux distribution. Alpine Linux is used because it is a lightweight, security-oriented distribution. Its small size (around 5 MB) reduces the attack surface and download time, making it ideal for building minimal and efficient Docker images.
```dockerfile
# Use the lightweight Alpine Linux image as the base image
FROM alpine:latest
```
Next, let's add some **LABEL** directives. Adding **LABEL** directives for maintainer, version, and environment provides essential metadata, aiding in documentation and maintainability. They help identify the image maintainer, track the image version, and specify the intended environment, making it easier to manage and support the image.
```dockerfile
# Note that these 3 LABEL directives will only create a single layer
LABEL maintainer="someguy@someorganization.com"
LABEL version="1.0"
LABEL environment="dev"
```
We are now going to update and upgrade our image OS. Running `apk update` and `apk upgrade` in your Docker image ensures that you have the latest package lists and the most recent security patches and bug fixes. This helps keep the image secure and up-to-date with the latest improvements, reducing potential vulnerabilities and improving stability.
```dockerfile
RUN apk update
RUN apk upgrade
```
Next we are going to use the **CMD** directive to pass the default text after our **You are reading** message.
```dockerfile
CMD ["Awesome posts in dev.to"]
```
Finally, we are going to add the **ENTRYPOINT** directive to define the default executable of the container
```dockerfile
ENTRYPOINT ["echo", "You are reading"]
```
The final **Dockerfile** should look something like the following:
```dockerfile
FROM alpine:latest
LABEL maintainer="someguy@someorganization.com"
LABEL version="1.0"
LABEL environment="dev"
RUN apk update && apk upgrade
CMD ["Awesome posts in dev.to"]
ENTRYPOINT ["echo", "You are reading"]
```
Save, and exit your editor.
---
In the next post, we'll discuss building a Docker image from a **Dockerfile**, but for now, let's give our image a try.
Run the following command inside the directory where you created your **Dockerfile**:
```powershell
docker image build .
```
This will build your image. We then need to find what our image is, so run the following
```powershell
docker image list
```
You should see a list of docker images stored in your local machine. We are looking for an image with no tag and no repository. This is the image we created:
```
REPOSITORY TAG IMAGE ID CREATED SIZE
<none> <none> 0b2db1f06f71 About a minute ago 16.5MB
```
Finally, use the `docker run <IMAGE ID>` to run our image:
```powershell
docker run 0b2db1f06f71
```
It should display the following:
```
You are reading Awesome posts in dev.to
```
---
Now let's pass some arguments. Run the following command to override the **CMD** argument:
```powershell
docker run 0b2db1f06f71 "hello world"
```
It should display the following:
```
You are reading hello world
```
## Summary
In this post, we explored how to use a Dockerfile to create custom Docker images. We began by explaining what a Dockerfile is and its syntax. We then covered some common Docker directives, such as **FROM**, **LABEL**, **RUN**, **CMD**, and **ENTRYPOINT**. Finally, we created our first Dockerfile using the directives we discussed.
In the next post, we are going to take a deep dive in building images through a **Dockerfile**. | kalkwst |

The **docker exec** command is very useful for quickly gaining access to a containerized instance for debugging, troubleshooting, and understanding the context the container is running in.
However, Docker containers run as per the life of the primary process running inside the container. When this process exits, the container will stop. If you need to access the primary process inside the container directly (as opposed to a secondary shell session), then you can use the **docker attach** command to attach to the primary running process inside the container.
When using **docker attach**, you can gain access to the primary process running in the container. If this process is interactive, such as a Bash shell session, you will be able to execute commands directly through a **docker attach** session. However, if the primary process in the container terminates, so will the entire container instance, since the Docker container lifecycle is dependent on the running state of the primary process.
Let's use the **docker attach** command to directly access the primary process of an Ubuntu container, and investigate the main container **entrypoint** process directly. By default, the primary process of this container is **/bin/bash**.
Use the **docker run** command to start a new Ubuntu container instance. Run the container in interactive mode (**-i**), allocate a TTY session (**-t**), and run it in the background (**-d**). Let's call this container **ubuntu-attach**.
```powershell
docker run -itd --name ubuntu-attach ubuntu:latest
```
The output should be something similar to the following:
```
Unable to find image 'ubuntu:latest' locally
latest: Pulling from library/ubuntu
00d679a470c4: Pull complete
Digest: sha256:e3f92abc0967a6c19d0dfa2d55838833e947b9d74edbcb0113e48535ad4be12a
Status: Downloaded newer image for ubuntu:latest
cf16890cbe41d199260e23b7eafd864b244c142aad776135ce8d9bd80d161e9c
```
Now you should have a brand new Ubuntu container instance named **ubuntu-attach** using the latest version of the Ubuntu container image.
---
Use the **docker ps** command to check that this container is running in our environment:
```powershell
docker ps
```
The details of the running container instance will be displayed. Take not that the primary process of the container is a Bash shell (**/bin/bash**)
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
cf16890cbe41 ubuntu:latest "/bin/bash" 3 minutes ago Up 3 minutes ubuntu-attach
```
---
Run the **docker attach** command to attach to the primary process inside the container. To do that, use the **docker attach** followed by the name or id of the container instance:
```powershell
docker attach ubuntu-attach
```
This should drop you into the primary Bash shell session of this container image. Your terminal session should change to a root shell session, indicating you have successfully accessed the container instance:
```
root@cf16890cbe41:/#
```
If you use commands such as **exit** to terminate a shell session, then your container instance because you are now attached to the primary process of the container instance. By default, docker provides the <kbd>Ctrl</kbd>+<kbd>P</kbd> and <kbd>Ctrl</kbd>+<kbd>Q</kbd> key sequence to gracefully detach from an **attach** session.
Upon successful detachment of the container, the words **read escape sequence** should be displayed before returning to your main terminal session:
```powershell
root@cf16890cbe41:/# read escape sequence
```
---
Use the **docker ps** command to verify that the container is still running as expected:
```powershell
docker ps
```
You should be able to see the **ubuntu-attach** container:
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
cf16890cbe41 ubuntu:latest "/bin/bash" 50 minutes ago Up 50 minutes ubuntu-attach
```
---
Attach to the container once more:
```powershell
docker attach cf16890cbe41
```
---
Now, terminate the primary process of this container using the **exit** command.
```
root@cf16890cbe41:/# exit
```
The terminal session should have exited, returning you once more to your primary terminal.
---
Use the **docker ps** command to observe that the **ubuntu-attach** container should no longer be running:
```powershell
docker ps
```
This should return no running container instances:
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
```
---
Use the **docker ps -a** command to view all the containers, even ones that have been stopped or have exited:
```powershell
docker ps -a
```
This should display the **ubuntu-attach** container in a stopped state:
```
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
cf16890cbe41 ubuntu:latest "/bin/bash" 2 hours ago Exited (0) 47 minutes ago ubuntu-attach
```
As you can see, the container has gracefully terminated (**Exited (0)**) approximately 47 minutes ago. The **exit** command gracefully terminated the Bash shell session.
Now you can also use the **docker system prune -fa** command to clean up the stopped container instances:
```powershell
docker system prune -fa
```
## Summary
In this post, we used the docker attach command to gain direct access to the primary process of a running container. This differs from the `docker exec` command we explored earlier in the chapter because docker exec executes a new process inside a running container, whereas docker attach attaches to the main process of a container directly. Careful attention must be paid, however, when attaching to a container not to stop the container by terminating the main process.
Although we have only scratched the surface of what Docker is capable of, I hope it was able to whet your appetite for the material that will be covered in the upcoming posts. In the next post, we will discuss building truly immutable containers using Dockerfiles and the docker build command. Writing custom Dockerfiles to build and deploy unique container images will demonstrate the power of running containerized applications at scale. | kalkwst |

1,881,313 | Power Platform Dataverse 101 | Everyone knows about the key pillars of the Power Platform: Power BI Power Apps Power... | 0 | 2024-06-24T05:57:50 | https://dev.to/wyattdave/power-platform-dataverse-101-11g5 | dataverse, powerplatform, powerapps, lowcode | Everyone knows about the key pillars of the Power Platform:
- Power BI
- Power Apps
- Power Automate
- Power Pages
- Copilot Studio (Formerly Power Virtual Agents)
But they are the pillars, what's the foundation that they are built on, well that's Dataverse (Except Power BI, but thats in the Power Platform in name only). Why do I say this, well 2 reasons:
- Data is the foundation to most systems
- The Platform is built on Dataverse.
The last one in interesting, as soon as something is solution aware its built on Dataverse
- Solution - solution table
- Flow - workflow table
- Connection Reference - connectionreference table
and the list goes on. So with this in mind I want to talk about Dataverse, and the basics to understand to get started with it are:
- History
- Using the Data
- Field/Data Types
- Access Controls
- Licenses
---
## History
Dataverse started out as the database for Dynamics before being recondition for the Power Platform. Its built on the [Common Data Model](https://learn.microsoft.com/en-us/common-data-model/), which is a shared schema designed to introduce standardisation (it's why it use to be called the Common Data Storage).
For some this is great, a bunch of prebuilt tables, for me personally its like all templates, great in theory but never 100% of what I need so I prefer to make my own.
## Using the Data
There are 5 main ways to access/update Dataverse data:
- Model driven App
- Canvas App
- Flow
- Table Designer
- API
_I know they are all really API but in this case I meant using the [Web API](https://learn.microsoft.com/en-us/power-apps/developer/data-platform/webapi/overview) and there are more like Power Query but I think these are the main ones for now_
**Model Driven**
The main way is a Model Driven app, as that is what it designed for, a front end to a Dataverse Table(s). Model Driven Apps are basically a Form and a Table view (I know there is a lot more but that is the core), so they allow you to create/update/delete in the form and view/delete in the list view. The classic designer, how to put this, was not user friendly, but the new designer is very simple and easy to use (if you have used SharePoint lists it will be even easier).
**Canvas App / Flows**
Canvas Apps and Flows access the table with the Dataverse Connectors.
These are API wrappers, prepackaged for easy use. There are 25 actions and counting (plus duplicates that allow access to different Dataverse environments).
**Table Designer**
The Table designer allows direct editing to the table (like Excel), along with uploading excel. Its not the best place to access or edit data as it is it really for configuring the table, but its good place for pre loading data when setting up the table.
**API**
Finally there is the API, this is probably the least used but also pretty cool. The API is built on [OData](https://www.odata.org/), which is a set of standards for the API structure, which makes it a lot easier to use (more info [here](https://dev.to/wyattdave/power-automate-get-items-parameters-25ac)). The API allows procode solutions/other systems to integrate with Dataverse.
## Field/Data Types
Dataverse has multiple different field types, starting with the standard:
- Text
- Number
- Date and Time
- Currency
- File
They also have preset formats for each:
Additionally have some more complex type:
- Choice
- Lookup
- Autonumber
- Formula
**Choice** are simple dropdown, with the added benefit of them being solution aware so can be reused across tables,
**Lookup** is a link to another table, with the added benefit that this allows Expanding (so you can pull fields from the lookup table into your table views).
**Autonumber** allows a sequential number/Date to be automatically created (like the SharePoint ID), more useful then you realise.
**Formula** is Power FX code that is related to the other values in the record (like SharePoint calculated column).
## Access Controls
The big strength on Dataverse is the access controls. SharePoint may be the database of choice for most people but they all know the pain, there is no row or field level security. So in SharePoint its view/edit all or edit own records, thats it.
For Dataverse we use Security Roles (yep the same roles we use to access the platform, everything in the Power Platform is Dataverse under the hood), we create new roles and then add rights to the table. We have full granularity to set if the role can Create, Read, Update, Delete records, and if they can see just their own records, your business groups or the entire org. The role can also be set to just one business group or org (set at the point of giving the role to a user/team).
The roles are solution aware, so can be added to solutions to be migrated across environments (and created/edited in the maker studio, not just admin center).
**Row Level**
Row level allows users to see groups of records (e.g UK team can see all only UK records). The ability to use row level secuirty must be turned on in features and then each record set to a business group (so entry in the form or a business process/plugin is needed).
_Business groups are created in each environment in the Admin center and permission set when giving the user a security role_
**Field Level**
Field level allows specific fields to break inherentance from the row. So a user may be able to edit a record but not a specific field (e.g. you create an approval request, they cant edit the field that says approved/not approved).
The field level security is enabled in the field settings
And then created it in the Admin Center under Column security profiles (this is also solution aware).
## Licenses
Nothing good in life is free, and its the same with Dataverse.
For starters to access any custom/cdm tables you need a premium license, thats same for Model Driven, Canvas and Flows (though I dont think for API).
Next is storage costs, you are provided some per premium license (250mb data, 2gb file) and some out of the box for the entire tenant, (10gb data, 20gb files, 20gb logs), there is no way of ring fencing per environment.
You can also buy storage addons
gb per month
Data: £30
Files: £1.50
Logs: £7.50
As an FYI Azure Data storage costs something like 20p per gb per month (with some conditions/caveats, especailly as this does not include compute costs, but you get the idea).
---
There is a lot more to go into but hopefully this covers the basics and the most important parts.

### My Journey Begins: Interning at High 6!
I'm excited to share that I've just started my internship at High 6, a dynamic website development company. As a Junior Laravel Developer Intern, I'm diving headfirst into the world of web development, and it's already proving to be an incredible experience.
#### Work-from-Home Setup
One of the perks of this internship is the work-from-home (WFH) setup. High 6 has seamlessly adapted to remote work, providing all the necessary tools and support to ensure we stay connected and productive. The flexibility of working from home allows me to maintain a healthy work-life balance, while also honing my skills in a comfortable environment.
#### Paid Internship
Did I mention that this is a paid internship? Yes, High 6 values the contributions of its interns and ensures that our efforts are rewarded. This financial support not only motivates me to give my best but also enables me to invest in resources that further my learning and development.
#### Role and Responsibilities
As a Junior Laravel Developer Intern, my primary focus is on learning and applying the Laravel framework, a powerful PHP framework designed for web artisans. But that's not all—I'm also getting hands-on experience with Vue.js and Inertia.js. These technologies work together seamlessly, allowing for the creation of dynamic, single-page applications with ease.
Here's a closer look at what I'm working on:
- **Laravel:** This robust PHP framework is the backbone of the projects I'm involved in. It's designed to make development straightforward and enjoyable, with elegant syntax and powerful features.
- **Vue.js:** A progressive JavaScript framework, Vue.js is perfect for building user interfaces and single-page applications. It's intuitive and integrates beautifully with Laravel.
- **Inertia.js:** This modern approach to building web apps bridges the gap between server-side and client-side frameworks. It enables me to develop complex applications without the need for a traditional API.
In addition to these technologies, I'm also getting my hands dirty with WordPress. High 6 is known for its diverse range of services, and developing WordPress websites is a key part of what we do. This experience broadens my skill set and ensures I'm well-versed in different aspects of web development.
#### Learning and Growth
Every day at High 6 is a learning opportunity. The team here is incredibly supportive and always ready to offer guidance and feedback. The collaborative environment encourages me to ask questions, experiment with new ideas, and continuously improve my skills.
I'm particularly excited about the projects I'll be working on in the coming months. From developing custom web applications to contributing to high-profile WordPress sites, the hands-on experience I'm gaining is invaluable.
#### Conclusion
Starting my internship at High 6 has been a fantastic journey so far. The combination of a supportive work-from-home setup, a paid internship, and the chance to work with cutting-edge technologies makes this an ideal opportunity for growth and development.
I'm looking forward to sharing more about my experiences and the exciting projects I'll be part of. Stay tuned for updates as I continue to learn, grow, and contribute to the amazing work being done at High 6! | harleygotardo |
