1,915,625 | 30+ Breaking Changes in TYPO3 v13.2 | Welcome to my TYPO3 v13 Feature Release series! In this blog, we'll discuss the recently released... | 0 | 2024-07-08T11:11:22 | https://dev.to/sanjaychauhan/30-breaking-changes-in-typo3-v132-12c5 | typo3, development, tutorial, programming | Welcome to my TYPO3 v13 Feature Release series!
In this blog, we'll discuss the recently released TYPO3 v13.2. This blog introduces [TYPO3 v13.2](https://t3planet.com/blog/typo3-v13-2/), highlighting its key features, breaking changes, and deprecations. Editors can expect significant improvements, and exciting enhancements are in store.
On July 2, 2024, TYPO3 Comunity released the Next TYPO3 v13 sprint series for the TYPO3 13.2 series. TYPO3 v13.2 focuses on making web development and management smoother. It delivers improvements for both editors and developers, with new features designed to streamline workflows, enhance user experiences, and provide powerful tools.
**Let’s Look into What’s New for you.**
**TYPO3 v13.2 for TYPO3 Integrators**
In TYPO3 version 13.2, TYPO3 introduces new ViewHelpers, enhances RecordTransformation, optimizes FileVersionNumber handling, offers Fluid Schema generation, and adds custom attributes to TagBasedViewHelpers, significantly improving template flexibility.
**TYPO3 v13.2 for TYPO3 Editors**
TYPO3 v13.2 is a significant update for both website creators and editors. It introduces a wave of improvements designed to make managing your website easier and faster. Editors will enjoy a much smoother workflow with features like a more powerful search function, easier navigation, and the ability to sort and copy forms.
**TYPO3 v13.2 for TYPO3 Developers**
[TYPO3 v13.2](https://t3planet.de/blog/typo3-v13-2/) also packs a punch for developers with several enhancements under the hood.
**Must Read Feature Series - **
Are you curious about the journey of TYPO3 v13 and its evolution from the [roadmap to v13.0](https://t3planet.com/blog/typo3-v13-roadmap-announcement/)/1? Don't miss out—explore my comprehensive blog below for an insider's perspective.
- [Roadmap Announcement of TYPO3 v13](https://t3planet.com/blog/typo3-v13-roadmap-announcement/)
- [What's New in TYPO3 v13.0?](https://t3planet.com/blog/typo3-v13-0/)
- [15+ Key Highlights in TYPO3 v13.1](https://t3planet.com/blog/typo3-v13-1/)
## The Story behind TYPO3 13.2's “Ready. Set. Ride.” Ocean Theme name.
TYPO3 v13 is designed to make life easier for backend editors and integrators. TYPO3 v13.2 updates the user interface (UI) to be more modern and user-friendly, with new features to simplify editing tasks. These improvements across the backend help editors work more smoothly and enjoyably.
## Major Braeking Changes & Enhancement in TYPO3 v13.2
**TYPO3 v13.2** is scheduled for **July 2, 2024**, following the third sprint release of the TYPO3 v13 series. With TYPO3 v13.2, over 30+ enhancements have been introduced.
**Let’s take a look at what’s new in TYPO3 v13.2.**
**Clear All Button at Notifications**
You can now clear all notifications at once with the new "**Clear All**" button, which appears when there are two or more notifications. Additionally, if the notification container height exceeds the viewport, a scroll bar will appear for easy navigation.
**Global Live Search Now Includes Backend Modules**
Backend Live Search now shows backend modules for easier navigation. Just click the search icon in the top right corner and select '**Backend Modules**'
**Manage PHP disable_functions via Admin Panel.**
Introducing a new configuration option in the Install Tool that lets you customize the environment check with a list of approved ‘ **disable_functions**’. Easily tailor your setup to meet your specific requirements.
**Set Default View Mode for Listing Resources**
Set Default View Mode for Listing Resources
In the TYPO3 Backend, particularly in the File > Filelist module, you can now switch between list and tile views for resource listings. By default, TYPO3 displays tiles unless a user preference is set.
Effortlessly customize your resource display mode to suit your workflow!
**Sorting & Duplicate TYPO3 Form Features**
TYPO3 users now have two exciting new features in the Form backend module. You can easily sort columns like Form Name, Locations, and Reference.
Plus, the new duplicate form feature lets you clone any form with a single click, making form management smoother.
**Renaming 'Access' Module to 'Permissions’**
In simpler terms, the update makes the module easier to find and understand. It uses clearer wording to show what the module does: manage permissions throughout your TYPO3 website.
**New Edit Columns Feature for List Module**
TYPO3 editors can now easily edit specific columns in the Filelist module.
Basic steps to follow -
- Go to Filelist.
- Select your folder.
- Check the files you want to edit.
- Click the 'Edit specific metadata' button."
**Create Presets for Data Export & Download**
Editors can now easily export data using predefined presets. Instead of selecting columns each time, they can choose from a list of presets created by the website maintainer or TYPO3 extension developers, making the export process quick and simple.
**Added New Work Space module for Global Live search**
The backend Live Search now shows workspaces accessible to users, allowing quick switches without using the Workspaces module. With the right permissions, users can go directly to the workspace's edit interface for faster and easier management.
To use this feature, click the search icon in the top right corner and select **Backend Modules**.
**Edit Record at “Check Links” Backend Module **
A new button in the Check Links backend module allows users to easily edit the full record of a broken link directly.
```
Usage in TypoScript
page = PAGE
page {
10 = PAGEVIEW
10 {
paths.10 = EXT:site_package/Resources/Private/Templates/
dataProcessing {
10 = database-query
10 {
as = mainContent
table = tt_content
select.where = colPos=0
dataProcessing.10 = record-transformation
}
}
}
}
```
**Usage in Fluid Template**
```
<!-- Any property, which is available in the Record (like normal) -->
{record.title}
{record.uid}
{record.pid}
<!-- Language related properties -->
{record.languageId}
{record.languageInfo.translationParent}
{record.languageInfo.translationSource}
<!-- The overlaid uid -->
{record.overlaidUid}
<!-- Types are a combination of the table name and the Content-Type name. -->
<!-- Example for table "tt_content" and CType "textpic": -->
<!-- "tt_content" (this is basically the table name) -->
{record.mainType}
<!-- "textpic" (this is the CType) -->
{record.recordType}
<!-- "tt_content.textpic" (Combination of mainType and record type, separated by a dot) -->
{record.fullType}
```
**Default Record Search Level Configuration**
In TYPO3, you can now set a default search level for the Web > List module and database browser using the new page TSconfig option mod.web_list.searchLevel.default. This makes record searches easier and ensures they automatically include the specified page tree levels.
**New 'Identifier' Property Added to Backend Layout**
In TYPO3 v13, Backend Layouts now have more properties for columns, making it easier for integrators to render page content without extensive TypoScript. The DataProcessor fetches all content elements from specified columns in a Backend Layout, which can then be accessed in Fluid Templates with {content."myIdentifier".records}.
**Here's an example of an enhanced Backend Layout definition:**
```
// EXT:my_sitepackage/Configuration/page.tsconfig
mod.web_layout.BackendLayouts {
default {
title = Default
config {
backend_layout {
colCount = 1
rowCount = 1
rows {
1 {
columns {
1 {
name = Main Content Area
colPos = 0
identifier = main
slideMode = slide
}
}
}
}
}
}
}
}
```
And here's how you can output it in the frontend:
```
page = PAGE
page.10 = PAGEVIEW
page.10.paths.10 = EXT:my_site_package/Tests/Resources/Private/Templates/
page.10.dataProcessing.10 = page-content
page.10.dataProcessing.10.as = myContent
<main>
<f:for each="{myContent.main.records}" as="record">
<h4>{record.header}</h4>
</f:for>
</main>
```
**Command to Generate Fluid Schema Files**
To enable autocompletion for all available ViewHelpers in supported IDEs, execute the following CLI command in your local development environment:
```
// CLI Commands to Generate Schema
vendor/bin/typo3 fluid:schema:generate
```
This command generates schema files that provide detailed ViewHelper information, improving development efficiency and accuracy.
```
<html
xmlns:f="http://typo3.org/ns/TYPO3/CMS/Fluid/ViewHelpers"
xmlns:my="http://typo3.org/ns/Vendor/MyPackage/ViewHelpers"
data-namespace-typo3-fluid="true"
>
```
**Database Error: 'Row Size Too Large' in MySQL and MariaDB**
In MySQL and MariaDB, modifying tables with many columns can cause a "Row size too large" error. TYPO3 core version 13 has implemented measures to handle this issue, so instance maintainers usually don't need to worry about the technical details.
**Custom Translations for Extbase Validators**
TYPO3 now supports custom translations for Extbase validators, allowing developers to create context-specific validation messages. This enhances user experience by providing meaningful messages tailored to each validator instance, like changing "**The given subject was empty**" to "The field '**Title**' is required."
```
// Example with translations
use TYPO3\CMS\Extbase\Annotation as Extbase;
#[Extbase\Validate([
'validator' => 'NotEmpty',
'options' => [
'nullMessage' => 'LLL:EXT:site_package/Resources/Private/Language/locallang.xlf:validation.myProperty.notNull',
'emptyMessage' => 'LLL:EXT:site_package/Resources/Private/Language/locallang.xlf:validation.myProperty.notEmpty',
],
])]
protected string $myProperty = '';
// Example with a custom string
use TYPO3\CMS\Extbase\Annotation as Extbase;
#[Extbase\Validate([
'validator' => 'Float',
'options' => [
'message' => 'A custom, non translatable message',
],
])]
protected float $myProperty = 0.0;
```
## Final Call For TYPO3 v13.3 Feature Freeze Version!
**TYPO3 v13.3**, releasing on **September 17, 2024**, will be the Feature Freeze version. Submit your feature suggestions now before it's too late!
## Most Awaited “Content Block” is here!
In TYPO3 v13.2, many behind-the-scenes changes are taking place, such as the groundwork for integrating Content Blocks using a new Schema API. While Content Blocks aren't fully integrated yet, the next milestone is TYPO3 v13.3, scheduled for release on September 17, 2024.
## TYPO3 Road map and Support
**Support Timeline**
Each TYPO3 sprint release (**from v13.0 to v13.3**) will be supported until the next minor version is released. TYPO3 v13 LTS (version 13.4) will receive bug fixes until April 30, 2026, and security patches until **October 31, 2027**.

1,915,629 | So Sánh Wix Và WordPress – Nên Lựa Chọn Nền Tảng Nào? | Wix và WordPress là hai nền tảng phổ biến để xây dựng website, mỗi nền tảng đều có những ưu và nhược... | 0 | 2024-07-08T11:15:10 | https://dev.to/terus_technique/so-sanh-wix-va-wordpress-nen-lua-chon-nen-tang-nao-2lm8 | website, digitalmarketing, seo, terus |
Wix và WordPress là hai nền tảng phổ biến để xây dựng website, mỗi nền tảng đều có những ưu và nhược điểm riêng. Wix là một công cụ [xây dựng website trực quan, dễ sử dụng](https://terusvn.com/thiet-ke-website-tai-hcm/), đặc biệt phù hợp với người mới bắt đầu. Với Wix, người dùng có thể dễ dàng tạo ra một website hoàn chỉnh mà không cần biết code, nhờ vào giao diện kéo-thả và các mẫu thiết kế sẵn có. Tuy nhiên, Wix lại hạn chế về khả năng tùy biến và không cho phép người dùng truy cập vào mã nguồn.
Khi so sánh hai nền tảng này, ta có thể thấy:
Mức độ dễ sử dụng: Wix dễ sử dụng hơn, đặc biệt với người mới bắt đầu. WordPress yêu cầu người dùng có một số kiến thức về lập trình và quản trị website.
Tốc độ: Wix thường có tốc độ nhanh hơn do không cần truy cập vào mã nguồn. Trong khi đó, WordPress có thể chậm hơn nếu website không được tối ưu hóa.
Thiết kế và tùy chỉnh: WordPress cung cấp nhiều tùy chỉnh hơn nhờ vào hệ sinh thái plugin và theme phong phú. Wix có ít tùy chỉnh hơn do giới hạn trong việc truy cập mã nguồn.
Bảo mật: WordPress có một cộng đồng lớn, do đó thường xuyên được cập nhật và vá lỗi bảo mật. Wix có ưu thế về bảo mật do được quản lý bởi một đơn vị duy nhất.
E-commerce: Cả hai nền tảng đều có các tính năng thương mại điện tử, nhưng WordPress có nhiều lựa chọn plugin hơn.
Di chuyển website: Di chuyển website từ Wix khó khăn hơn do không thể truy cập mã nguồn. Trong khi đó, WordPress cho phép người dùng dễ dàng di chuyển website.
Giá cả: Wix có các gói dịch vụ trả phí, trong khi WordPress là miễn phí về bản thân CMS, nhưng người dùng phải tự chi trả cho hosting, tên miền và các plugin/theme.
Tóm lại, cả Wix và WordPress đều là những nền tảng tốt để [xây dựng website](https://terusvn.com/thiet-ke-website-tai-hcm/), nhưng lựa chọn nền tảng nào sẽ phụ thuộc vào nhu cầu, kinh nghiệm và ngân sách của người dùng. Người mới bắt đầu thường chọn Wix do dễ sử dụng, còn những người có kiến thức về lập trình và muốn tùy biến nhiều thường ưu tiên WordPress.

Now, we will implement an authentication system to ensure that only authorized users can access their passwords, preventing other users from viewing them. We will also ensure that only logged-in users can save their passwords.
To simplify this process, we are using Google Cloud Platform to create an OAuth system and store user data in our MySQL database. In the database, there will be a new table called users that will relate to the passwords table. This relationship is essential to ensure that each password is securely associated with the correct user.
On the frontend, we will use the @react-oauth/google library, which will handle the interaction with Google API on the client side, manage the authentication state, and even display the login popup.

**説明**フィードバックに基づき、PubNubのApp Context APIを使用したユーザー、チャンネル、メンバーシップデータのフィルタリングに関する様々なSDKからの情報を見直し、統一しました。その結果、データフィルタリングクエリのエントリポイントとして機能する[App Context Filtering](https://pubnub.com/docs/general/metadata/filtering)ドキュメントを1つ作成しました。
学びましょう：
- どのユーザー、チャネル、およびメンバーシップデータをフィルタリングできるか。
- どのフィルタリング演算子を使用するか。
- 実践的な例を通して、どのようにデータをフィルタリングできるか。
```js
pubnub.objects.getAllChannelMetadata({
filter: '["description"] LIKE "*support*"'
})
```
SDK 📦 イベントリスナーアーキテクチャの更新
-------------------------
### PythonとAsyncioのイベントリスナーアーキテクチャの更新
**タイプ**新機能
**説明** [Pythonと](https://pubnub.com/docs/sdks/python/api-reference/publish-and-subscribe) [Asyncio](https://pubnub.com/docs/sdks/asyncio/api-reference/publish-and-subscribe)SDKのための新しいイベントリスナーアーキテクチャは、以前のモノリシックなPubNubオブジェクトと比較して、サブスクリプションを管理し、イベントをリッスンする、より狭いスコープの方法を導入しています。
PubNubオブジェクトは依然としてグローバルスコープとして機能し、下位互換性を維持していますが、新しいアーキテクチャでは、Subscriptionオブジェクトを返すチャネル、チャネルグループ、ユーザーメタデータ、チャネルメタデータなどの「エンティティ」オブジェクトを提供しています。
これらのSubscriptionは、単一のエンティティに固有のsubscribe/unsubscribeメソッドと`addListener/``removeListener`メソッドを可能にし、リアルタイムイベントを管理する、より柔軟で独立した方法を提供し、グローバルな状態管理の必要性を低減します。
```js
# entity-based, local-scoped
subscription = pubnub.channel(f'{channel}').subscription(with_presence: bool = False)
```
Chat 💬チャット
-----------
### チャットSDKの安全なモデレーション用サンプル
**タイプ**新機能
**説明**チャットチームは、Access ManagerでチャットSDKアプリを保護するためのエンドツーエンドのシナリオを理解するのに役立つシンプルな[Access Manager APIサービスを](https://github.com/pubnub/js-chat/blob/master/samples/access-manager-api/README.md)作成しました。このサービスはシンプルなエンドポイントをモックし、Access Managerを有効にしたチャットSDKアプリのサーバーサイド認証をセットアップするために使用できるサンプル権限セットを含んでいます。
私たちのReact Native Chat App（ユーザーとの対話用）、Channel Monitor（ミュートや禁止などのユーザーモデレーション用）、およびAccess Manager API（認可トークンの生成用）を使用して、すべてのテストシナリオを実行します。
詳細な手順については、[BizOps Workspace](https://www.pubnub.com/how-to/securely-moderate-chat-and-users/?utm_source=devto&utm_medium=syndication&utm_campaign=off_domain&utm_content=ja)ブログの[How to Securely Moderate Chat and Usersを](https://www.pubnub.com/how-to/securely-moderate-chat-and-users/?utm_source=devto&utm_medium=syndication&utm_campaign=off_domain&utm_content=ja)参照してください。
インサイト ↪So\_1F4CA
----------------
### デバイスメトリクスダッシュボード
**タイプ**機能強化
**説明**インサイトの`ユーザー行動`ダッシュボードを拡張し、[デバイスタイプのメトリクスを](https://pubnub.com/docs/pubnub-insights/dashboards/user-behavior)追加しました。これにより、デバイスタイプごとのユーザーの行動を深く掘り下げることができます。今後、アプリのユーザーが最も頻繁に公開または購読する場所（iOS、Android、Windows）を観察し、デバイスタイプごとのユニークユーザー数を確認できます。
この洞察は、デバイス別にカスタム機能を構築し、顧客体験を向上させるのに役立ちます。
イベントとアクション ⚡ ウェブフックアクションがバッチ処理に対応しました。
--------------------------------------
### Webhookアクションがバッチ処理に対応
**タイプ**機能強化
**説明**イベント＆アクションの[バッチ](https://pubnub.com/docs/serverless/events-and-actions/events#batching)機能を使うと、イベントを個別に送信するのではなく、1つのリクエストで送信することで、大量のイベントを管理できます。この機能は5月より[Webhookアクション](https://pubnub.com/docs/serverless/events-and-actions/actions/create-webhook-action)タイプでも利用できるようになりました。
### (アン)エンベロープ
**タイプ**機能拡張
**説明**全てのアクションのペイロードを[エンベロープで](https://pubnub.com/docs/serverless/events-and-actions/events#envelope)ラップできるようになった。つまり、ペイロードスキーマに詳細なEvents & Actions JSONメタデータを含めるかどうかを選択できる。ペイロードが送信されたチャンネルや、それをトリガーしたリスナーに関する情報のように、ペイロード以外のメタデータを使いたい場合に役立つかもしれません。
イルミネーション 💡。

### 積み上げ棒グラフ
**タイプ**新機能
**説明**棒グラフと折れ線グラフに加えて、Illuminateダッシュボードでは、1つのチャート上に多くのディメンションと値がある場合にデータの可読性を向上させる、新しい積み[重ね棒](https://pubnub.com/docs/illuminate/dashboards/basics#settings)タイプのチャートを提供するようになりました。
### 変数
**タイプ**機能強化
**説明**Decisionsでアクションを作成するとき（収集したメトリクスで何をしたいかを記述する）、アクション構成テーブルに[変数を](https://pubnub.com/docs/illuminate/decisions/basics#decision-structure)追加して、参照するものを制御し、動的に変更することができます。定義済みの条件を参照したり`（${と`入力してリストから選択）、新しい変数`（${変数}）を`設定したりすることで、より柔軟に変数を使用できます。変数はアクションの**ペイロードや** **ボディだけ**でなく、ほとんどのアクションフィールドで利用できるようになりました。
### データマッピングフィールドの改善
**タイプ**機能強化
**説明**ビジネスオブジェクトを作成し、メジャー（追跡したいデータ）またはディメンション（追跡するものをセグメント化する）を定義するとき、Illuminateにこのデータを探すべき場所を知らせるために、フィールド名をペイロードの実際のフィールドにマッピングする必要があります。これまでは、特定のペイロードフィールドの正確なマッピングを手動で入力する必要がありました。5月現在、Illuminateは、正確なPublishおよびApp Contextデータの場所を見つけるために、よりユーザーフレンドリーな[ドロップダウンメニューを](https://pubnub.com/docs/illuminate/business-objects/basics#data-mapping)提供しています。

일반 🛠️
------
### 앱 컨텍스트 데이터 필터링에 대한 통합 정보
**유형**: 향상
**설명**: 피드백을 바탕으로 다양한 SDK의 사용자, 채널, 멤버십 데이터 필터링에 대한 정보를 검토하고 PubNub의 앱 컨텍스트 API를 사용하여 통합했습니다. 그 결과, 모든 데이터 필터링 쿼리의 시작점 역할을 하는 하나의 [앱 컨텍스트 필터링](https://pubnub.com/docs/general/metadata/filtering) 문서(수많은 예시로 뒷받침됨)를 만들었습니다.
알아보기:
- 어떤 사용자, 채널, 멤버십 데이터를 필터링할 수 있는지 알아보세요.
- 사용할 필터링 연산자.
- 실제 예제를 통해 데이터를 필터링하는 방법.
```js
pubnub.objects.getAllChannelMetadata({
filter: '["description"] LIKE "*support*"'
})
```
SDK 📦

### Python 및 Asyncio용 이벤트 리스너 아키텍처 업데이트
**유형에** 대한 업데이트된 이벤트 리스너 아키텍처: 새로운 기능
**설명**: [Python](https://pubnub.com/docs/sdks/python/api-reference/publish-and-subscribe) 및 [Asyncio](https://pubnub.com/docs/sdks/asyncio/api-reference/publish-and-subscribe) SDK를 위한 새로운 이벤트 리스너 아키텍처는 이전의 모놀리식 PubNub 객체에 비해 구독을 관리하고 이벤트를 수신하는 보다 좁은 범위의 방법을 도입했습니다.
PubNub 개체는 여전히 글로벌 범위로 사용되며 이전 버전과 호환되지만, 새로운 아키텍처는 채널, 채널 그룹, 사용자 메타데이터, 채널 메타데이터와 같은 '엔티티' 개체를 제공하여 구독 개체를 반환합니다.
이러한 구독은 단일 엔티티에 특정한 구독/구독 취소 메서드와 `addListener/removeListener` 메서드를 허용하여 실시간 이벤트를 보다 유연하고 독립적으로 관리할 수 있는 방법을 제공하고 글로벌 상태 관리의 필요성을 줄여줍니다.
```js
# entity-based, local-scoped
subscription = pubnub.channel(f'{channel}').subscription(with_presence: bool = False)
```
Chat 💬
-------
### Chat SDK에서 보안 모더레이션을 위한 샘플
**유형**: 새 기능
**설명**: 저희 채팅팀은 Access Manager를 사용하여 Chat SDK 앱을 보호하는 엔드투엔드 시나리오를 이해하는 데 도움이 되는 간단한 [Access Manager API 서비스를](https://github.com/pubnub/js-chat/blob/master/samples/access-manager-api/README.md) 만들었습니다. 이 서비스는 간단한 엔드포인트를 모의하며 Access Manager가 사용 설정된 Chat SDK 앱에 대한 서버 측 인증을 설정하는 데 사용할 수 있는 샘플 권한 집합을 포함합니다.
리액트 네이티브 채팅 앱(사용자 상호작용용), 채널 모니터(뮤트 및 차단과 같은 사용자 관리용), 액세스 관리자 API(권한 토큰 생성용)를 사용하여 전체 테스트 시나리오를 진행하세요.
자세한 단계는 [BizOps 워크스페이스로 채팅 및 사용자를 안전하게 중재하는 방법](https://www.pubnub.com/how-to/securely-moderate-chat-and-users/?utm_source=devto&utm_medium=syndication&utm_campaign=off_domain&utm_content=ko) 블로그를 참조하세요.
인사이트 📊
-------
### 장치 메트릭 대시보드
**유형**: 향상
**설명**: 인사이트의 `사용자 행동` 대시보드에 [디바이스 유형 지표를](https://pubnub.com/docs/pubnub-insights/dashboards/user-behavior) 포함하도록 확장했습니다. 이를 통해 디바이스 유형별 사용자 행동을 자세히 살펴볼 수 있습니다. 이제부터 앱 사용자가 가장 자주 게시하거나 구독하는 위치(iOS, Android, Windows)를 관찰하고 디바이스 유형별 고유 사용자 수를 확인할 수 있습니다.
이러한 인사이트를 통해 디바이스별 맞춤 기능을 구축하여 고객 경험을 개선할 수 있습니다.
이벤트 및 액션 ⚡
----------
### 이제 웹훅 액션이 일괄 처리를 지원합니다.
**유형**: 개선
**설명**: 이벤트 및 작업의 일괄 [처리](https://pubnub.com/docs/serverless/events-and-actions/events#batching) 기능을 사용하면 각 이벤트를 개별적으로 보내지 않고 한 번의 요청으로 전송하여 대량의 이벤트를 관리할 수 있습니다. 이 기능은 5월부터 [웹훅 액션](https://pubnub.com/docs/serverless/events-and-actions/actions/create-webhook-action) 유형에서도 사용할 수 있습니다.
### (언)엔벨로핑
**유형**: 개선
**설명**: 이제 모든 액션의 페이로드를 [봉투로](https://pubnub.com/docs/serverless/events-and-actions/events#envelope) 감쌀 수 있습니다. 즉, 페이로드 스키마에 자세한 이벤트 및 액션 JSON 메타데이터를 포함할지 여부를 선택할 수 있습니다. 페이로드가 전송된 채널이나 페이로드를 트리거한 리스너에 대한 정보와 같이 페이로드 외부의 메타데이터를 사용하려는 경우에 유용할 수 있습니다.
일루미네이트 💡
---------
### 누적 막대 차트
**유형**: 새로운 기능
**설명**: 이제 막대형 차트와 꺾은선형 차트에 더해, 하나의 차트에 많은 차원과 값이 있을 때 데이터 가독성을 높여주는 새로운 [누적 막](https://pubnub.com/docs/illuminate/dashboards/basics#settings) 대형 차트 유형이 Illuminate 대시보드에서 제공됩니다.
### 변수
**유형**: 향상
**설명**: 의사 결정에서 작업(수집된 메트릭으로 수행하려는 작업을 명시)을 만들 때 작업 구성 테이블에 [변수를](https://pubnub.com/docs/illuminate/decisions/basics#decision-structure) 추가하여 참조하는 대상을 제어하고 동적으로 변경할 수 있습니다. 미리 정의된 조건을 참조하거나( `${를` 입력하고 목록에서 선택), 필요에 따라 새 변수`(${변수})`를 설정하는 등 변수를 더욱 유연하게 사용할 수 있습니다. 이제 변수는 액션의 **페이로드** 또는 **본문뿐만** 아니라 대부분의 액션 필드에 사용할 수 있습니다.
### 개선된 데이터 매핑 필드
**Type**: 개선됨
**설명**: 비즈니스 개체를 만들고 측정값(추적하려는 데이터) 또는 차원(추적 대상 세분화)을 정의할 때, 필드 이름을 페이로드의 실제 필드에 매핑해야 Illuminate가 이 데이터를 찾을 위치를 알 수 있습니다. 지금까지는 특정 페이로드 필드의 정확한 매핑을 수동으로 입력해야 했습니다. 5월부터 일루미네이트는 정확한 퍼블리시 및 앱 컨텍스트 데이터 위치를 찾을 수 있는 보다 사용자 친화적인 [드롭다운 메뉴를](https://pubnub.com/docs/illuminate/business-objects/basics#data-mapping) 제공합니다.

try:
text = extract_text_from_pdf(fp)
sentences = split_into_sentences(text)
texts.append(" ".join(sentences))
except Exception as e:
print(f"Error processing file {fp}: {e}")
texts.append("")
data = pd.DataFrame({
"Author": authors,
"Title": titles,
"Text": texts
})
data.to_csv(output_file, index=False, quoting=1, encoding='utf-8')
print(f"Data has been written to {output_file}")
```
### Loading Stopwords

1,915,634 | Nguyên Lý Thị Giác Là Gì? Ứng Dụng Trong Thiết Kế Website | Nguyên tắc trực quan (Visual principles) là những quy tắc, nguyên lý cơ bản liên quan đến cách con... | 0 | 2024-07-08T11:19:34 | https://dev.to/terus_digitalmarketing/nguyen-ly-thi-giac-la-gi-ung-dung-trong-thiet-ke-website-27b9 | Nguyên tắc trực quan (Visual principles) là những quy tắc, nguyên lý cơ bản liên quan đến cách con người nhìn và cảm nhận thông tin thông qua thị giác. Khi áp dụng các nguyên tắc này vào thiết kế, chúng giúp tạo ra các sản phẩm trực quan hài hòa, dễ hiểu và thu hút người dùng. Các nguyên tắc trực quan chính bao gồm:
1. Nguyên lý thị giác cân bằng (Balance): Cân bằng là một trong những nguyên lý cơ bản nhất của thiết kế trực quan. Nó nhấn mạnh rằng các yếu tố trên trang web cần được sắp xếp một cách hài hòa, tạo cảm giác ổn định và hài lòng cho người dùng. Cân bằng có thể đạt được thông qua việc sử dụng các yếu tố như kích thước, hình dạng, màu sắc và vị trí các thành phần trên trang.
2. Nguyên lý thị giác căn lề (Alignment): Căn lề là việc sắp xếp các yếu tố trên trang web theo một hướng nhất định, tạo cảm giác thống nhất và dễ nhìn. Căn lề giúp tăng tính chuyên nghiệp, gọn gàng và dễ đọc cho trang web. Nó cũng giúp người dùng dễ dàng định hướng và tập trung vào nội dung chính.
3. Nguyên lý thị giác nhấn mạnh (Emphasis): Nhấn mạnh là việc sử dụng các yếu tố như kích thước, màu sắc, vị trí để thu hút sự chú ý của người dùng vào những thông tin quan trọng. Điều này giúp tạo điểm nhấn và giúp người dùng dễ dàng xác định các phần quan trọng trên trang web.
4. Nguyên lý thị giác không gian âm (White Space): Không gian âm, hay còn gọi là khoảng trống, là vùng trống xung quanh các yếu tố trên trang web.

1,915,682 | Deploying a Web-app with Elastic Beanstalk | So a few months ago I made an E-commerce store as a personal project. I'll be deploying it today... | 0 | 2024-07-08T11:43:45 | https://dev.to/aktran321/deploying-a-web-app-with-elastic-beanstalk-37hb | So a few months ago I made an E-commerce store as a personal project. I'll be deploying it today (again) with Elastic Beanstalk and documenting the process.
## 1. Elastic Beanstalk
For my MacOs machine, I have to install Homebrew. Once installed, run commands:
* brew update
* brew install awsebcli
* eb --version
Create a .ebextensions folder in the root directory of the Django application and inside it, a django.config file
```
option_settings:
aws:elasticbeanstalk:container:python:
WSGIPath: <app name>.wsgi:application
```
For me, the <app name> would be replaced with "ecom".
The name it consistent with this line in my settings.py:
```
WSGI_APPLICATION = "ecom.wsgi.application"
```
Since my project is in Django, I have to move to my root directory here,
If you're in your virtual environment, deactivate it by running:
* deactivate
Enter the project directory:
* cd ecom
Then run:
* eb init
I already have an Elastic Beanstalk config.yaml file it will only prompt me to setup SSH for my instances, however if I did not already launch it, it would ask which AZ to use, an application name, language, and platform I want to use.
Run
* eb create
This will create the Ec2 instances, security groups, CloudWatch logs and alarms, load balancers, an S3 bucket, etc.
I chose an application load balancer, "No" to Spot fleet requests, and chose default options for the rest of the prompts.
After a 5-10 min, the environment is then successfully created.
Running the command
* eb open
Opens the project successfully on the web browser.
Now in the settings.py file:
Take the URL and add in this line of code:
```
CSRF_TRUSTED_ORIGINS = ['<http://EB URL>']
```
This allows you to make POST requests to the website through HTTP.
When making any changes to the project, save and run:
* eb deploy
## 2. Route 53
Since the site is only using HTTP, I want to use Route53 to buy a domain and and register an SSL certificate. I used the SSL certificate to help create the 2 CNAME records I need to prove I own shoptop.click and www.shoptop.click. Next, I created 2 more A records for shoptop.click and www.shoptop.click, using them as an alias to point to my Elastic Beanstalk environment.
The settings.py file needs to be updated as well to include the new domain name.
```
CSRF_TRUSTED_ORIGINS = ["https://shoptop.click", "https://www.shoptop.click"]
```
## 3. EC2 Load Balancer
Currently, the load balancer is routing traffic from HTTP to the application, but I want to route the HTTP traffic to HTTPS.
So in the EC2 console I found my load balancer and clicked add listener
I then select the HTTPS protocol, which automatically selects port 443.
For "**Routing Actions**", I chose "**forward to target groups**" and chose my "**awseb-...**" target group that was automatically created with Elastic Beanstalk.
Then for the SSL/TLS certificate, I select "From "ACM" and look for the certificate that I created for my domain shoptop.click.
Now add the listener.
Currently, the HTTPS is not reachable, since the security group still needs to be edited. But first, the HTTP listener needs to be edited to route to my new HTTPS listener instead of directly to my application.
All this requires is to edit the listener and edit the "**Routing Actions**" and choose to redirect to URL. Choose HTTPS and port 443.
## 4. Security Group
While still in the EC2 console, I edited the security group by clicking "**Security Groups**" on the left sidebar. I found the "**AWSELBLoadBalancerSecurityGroup...**" and choose to edit its inbound rules.
Here is the configuration:
Now looking back at the load balancer, there is no longer an error for the HTTPS listener.
Shoptop is now up and running easily with Elastic Beanstalk and securely with HTTPS.
Moving forward, I want to look into securing the database against SQL injections utilizing AES, which might run up costs (this project is costing ~$100/mo already while running on AWS). I already had almost 20 fake users on the site only a day after I launched. Apparently email confirmation isn't enough to stop bots, but I implemented CAPTCHAv2 and haven't had a problem since. | aktran321 | |

### (Un)umhüllend
**Typ**: Erweiterung
**Beschreibung**: Sie können nun die Nutzdaten jeder Aktion in einen [Umschlag](https://pubnub.com/docs/serverless/events-and-actions/events#envelope) verpacken, d.h. wählen, ob das Nutzdatenschema detaillierte Events & Actions JSON-Metadaten enthalten soll. Dies kann hilfreich sein, wenn man Metadaten außerhalb des Payloads verwenden möchte, wie z.B. Informationen über den Kanal, an den der Payload gesendet wurde oder den Listener, der ihn ausgelöst hat.
Beleuchten 💡.
--------------
### Gestapelte Balkendiagramme
**Typ**: Neue Funktion
**Beschreibung**: Zusätzlich zu den Balken- und Liniendiagrammen bieten Illuminate Dashboards jetzt einen neuen Diagrammtyp [mit gestapelten Balken](https://pubnub.com/docs/illuminate/dashboards/basics#settings), der die Lesbarkeit von Daten verbessert, wenn viele Dimensionen und Werte in einem einzigen Diagramm dargestellt werden.
### Variablen
**Typ**: Erweiterung
**Beschreibung**: Wenn Sie in Decisions Aktionen erstellen (die angeben, was Sie mit den gesammelten Metriken tun möchten), können Sie in den Aktionskonfigurationstabellen [Variablen](https://pubnub.com/docs/illuminate/decisions/basics#decision-structure) hinzufügen, um zu steuern und dynamisch zu ändern, worauf sie sich beziehen. Sie können Variablen flexibler verwenden - entweder durch Bezugnahme auf die vordefinierten Bedingungen (geben Sie `${)` ein und wählen Sie aus der Liste aus) oder indem Sie neue Variablen`(${variable}`) einrichten. Variablen sind jetzt für die meisten Aktionsfelder verfügbar, nicht nur in der **Nutzlast** oder dem **Body** von Aktionen.
### Verbesserte Datenzuordnungsfelder
**Typ**: Verbesserung
**Beschreibung**: Wenn Sie ein Business-Objekt erstellen und Kennzahlen (welche Daten Sie verfolgen wollen) oder Dimensionen (um die zu verfolgenden Daten zu segmentieren) definieren, müssen Sie die Feldnamen den tatsächlichen Feldern in Ihrer Payload zuordnen, damit Illuminate weiß, wo diese Daten gesucht werden sollen. Bislang mussten Sie die genaue Zuordnung der einzelnen Felder in der Nutzlast manuell eingeben. Ab Mai bietet Illuminate benutzerfreundlichere [Dropdown-Menüs](https://pubnub.com/docs/illuminate/business-objects/basics#data-mapping), um den genauen Speicherort der Veröffentlichungs- und App-Kontextdaten zu ermitteln.
Sonstiges 🌟.
-------------
### Neue Suche und KI-Assistent
**Typ**: Neue Funktion
**Beschreibung**: Zu guter Letzt haben wir die Algolia-Suche in unseren Dokumenten gegen die neue kombinierte Suche und den KI-Assistenten ausgetauscht, um das PubNub-Lernabenteuer noch genauer und interaktiver zu gestalten.
Es ist an der Zeit, Ihr Coding-Spiel zu verbessern und sich mit unserem neuen KI-Assistenten und der Suchfunktion anzufreunden. Wir werden sie auf der Grundlage deines Feedbacks verfeinern.

1,915,657 | Improve Data Accuracy with Automated Data Lineage | Manta-Prolifics Microsoft Purview Connector (MPP) Today’s hybrid workspaces require data to be... | 0 | 2024-07-08T11:23:06 | https://dev.to/kalyaniprolific/improve-data-accuracy-with-automated-data-lineage-2e9f | ##
[Manta-Prolifics Microsoft Purview Connector](https://prolifics.com/us/expertise/data-ai/manta-prolifics-purview-connector) (MPP)
Today’s hybrid workspaces require data to be accessed from a plethora of devices, apps and services across the globe. Data governance is not easy. You need a methodology and approach and a strategy to get it right. And lineage is just one piece of the major puzzle that is governance.
The Manta-Prolifics Microsoft Purview (MPP) Connector is designed to enhance the data lineage capabilities for Microsoft Purview customers beyond standard features. It’s created for systems where data lineage isn’t automatically captured and empowers users to leverage Manta for automatic collection of lineage information, without the hassle of custom development.
A recent study by Forrester Consulting highlights that only 42% of organizations have the competence to train [Gen AI](https://prolifics.com/us/expertise/generative-ai) models, while a massive 89% fail at getting business data ready for Gen AI. Moreover, only 23% of the organizations have implemented a governance plan.
**Capabilities of MPP Connector**
Seamlessly integrating this data into Purview, MPP offers a comprehensive lineage view, enabling better tracing of data journeys across on-premises, multi-cloud, and software as a service (SaaS) data. Rolling out new capabilities help organizations integrate Manta into their own data governance solutions, including Microsoft Purview, so they can make headway in their [digital transformation](https://prolifics.com/us) journeys.

1,915,721 | Bitpower’s revolutionary innovation | Blockchain technology is one of the revolutionary innovations in the field of financial technology... | 0 | 2024-07-08T12:17:25 | https://dev.to/pings_iman_934c7bc4590ba4/bitpowers-revolutionary-innovation-1i9b |
Blockchain technology is one of the revolutionary innovations in the field of financial technology in recent years, which has greatly changed the traditional financial model. As an innovator in the blockchain field, BitPower has launched a series of blockchain-based decentralized finance (DeFi) solutions, especially in lending and liquidity provision, and has achieved remarkable results.
BitPower relies on the transparency, security and decentralization features of blockchain technology to establish a completely decentralized lending platform - BitPower Loop. The platform runs on Binance Smart Chain (BSC) and utilizes smart contracts to achieve automation and immutability of all transactions. Through BitPower Loop, users can conduct decentralized lending safely and conveniently, and enjoy real-time market interest rates and flexible asset mortgage services.
The core of BitPower Loop lies in its market liquidity pool model, in which users can participate as fund suppliers or borrowers. Fund providers earn income by depositing assets into smart contracts, while borrowers can use encrypted assets as collateral for loans and enjoy low-interest borrowing services. All operations are automatically executed through smart contracts, ensuring transparency and security of transactions.
In addition, BitPower has also greatly motivated users to participate by introducing new Circulation Returns and Referral Rewards mechanisms. Users can obtain daily or long-term high returns by providing liquidity, while receiving additional referral rewards by inviting new users to join the platform. These reward mechanisms not only increase users’ income sources, but also promote the rapid development of the platform ecosystem.
In terms of security, BitPower adopts multiple protection mechanisms to ensure the safety of user assets. All transaction records are open and transparent, can be queried on the blockchain, and cannot be tampered with by anyone. In addition, the non-tamperability of smart contracts ensures the stability and reliability of platform operation. Even the founder of the platform cannot change the content of smart contracts.
In general, BitPower takes advantage of blockchain technology to create a fair, secure and efficient decentralized financial platform, providing convenient financial services to users around the world. Through BitPower, users can not only enjoy the convenience brought by financial technology, but also obtain generous benefits by participating in the platform ecosystem, truly realizing the value of blockchain technology in the financial field. @Bitpower | pings_iman_934c7bc4590ba4 | |
1,915,663 | Notes de mise à jour de la documentation - mai 2024 | Découvrez tous les points forts de la documentation de mai 2024. | 0 | 2024-07-08T11:27:43 | https://dev.to/pubnub-fr/notes-de-mise-a-jour-de-la-documentation-mai-2024-1ekp | pubnub, documentation, releases, releasenotes | Cet article a été publié à l'origine sur [https://www.pubnub.com/docs/release-notes/2024/may](https://www.pubnub.com/docs/release-notes/2024/may?utm_source=devto&utm_medium=syndication&utm_campaign=off_domain&utm_content=fr)
Bienvenue dans les notes de version de ce mois-ci ! PubNub vous apporte un ensemble de mises à jour conçues pour rationaliser votre travail et ajouter une touche de commodité.
Que contient ce paquet ?
Nous avons unifié la documentation sur le filtrage des données App Context, revu l'architecture de l'écouteur d'événements pour Python et Asyncio, et ajouté de nouveaux outils visant à vous aider à démarrer avec la modération sécurisée des chats.
Sur le front du portail d'administration, nous avons amélioré notre jeu avec des métriques détaillées sur les appareils, amélioré la gestion des événements avec des options de mise en lot et d'enveloppement, et déployé de nouveaux graphiques à barres empilées et des fonctionnalités variables dans Illuminate.
De plus, nos documents et notre site Web disposent désormais d'un nouveau moteur de recherche doté d'une intelligence artificielle pour vous aider à trouver exactement ce dont vous avez besoin.
Plongez dans l'aventure et explorez les nouveautés !
Généralités 🛠️
---------------
### Info unifiée sur le filtrage des données App Context
**Type**: Amélioration
**Description**: Sur la base des retours, nous avons revu et unifié les informations des différents SDKs sur le filtrage des données des utilisateurs, des canaux et des membres en utilisant l'API App Context de PubNub. En conséquence, nous avons créé un document sur le [filtrage du contexte applic](https://pubnub.com/docs/general/metadata/filtering) atif (étayé par de nombreux exemples) qui sert de point d'entrée pour toutes les requêtes de filtrage de données.
Apprenez :
- Quelles données sur les utilisateurs, les canaux et les membres vous pouvez filtrer.
- Quels opérateurs de filtrage utiliser.
- Comment vous pouvez filtrer les données à l'aide d'exemples pratiques.
```js
pubnub.objects.getAllChannelMetadata({
filter: '["description"] LIKE "*support*"'
})
```
SDKs 📦
-------
### Mise à jour de l'architecture des écouteurs d'événements pour Python et Asyncio
**Type**: Nouvelle fonctionnalité
**Description**: La nouvelle architecture d'écoute d'événements pour les SDK [Python](https://pubnub.com/docs/sdks/python/api-reference/publish-and-subscribe) et [Asyncio](https://pubnub.com/docs/sdks/asyncio/api-reference/publish-and-subscribe) introduit des moyens plus restreints de gérer les abonnements et d'écouter les événements par rapport à l'objet monolithique PubNub précédent.
Alors que l'objet PubNub sert toujours de portée globale et reste compatible avec le passé, la nouvelle architecture propose des objets "entités" tels que des canaux, des groupes de canaux, des métadonnées d'utilisateurs et des métadonnées de canaux qui renvoient des objets "Subscription" (abonnement).
Ces abonnements permettent d'appliquer des méthodes de souscription/désabonnement et des méthodes d'`ajout/suppression` `d'auditeurs` spécifiques à des entités uniques, offrant un moyen plus souple et indépendant de gérer les événements en temps réel et réduisant la nécessité d'une gestion globale de l'état.
```js
# entity-based, local-scoped
subscription = pubnub.channel(f'{channel}').subscription(with_presence: bool = False)
```
Chat 💬
-------
### Exemple de modération sécurisée dans Chat SDK
**Type**: Nouvelle fonctionnalité
**Description**: Notre équipe de chat a créé un [service API Access Manager](https://github.com/pubnub/js-chat/blob/master/samples/access-manager-api/README.md) simple pour vous aider à comprendre le scénario de bout en bout pour sécuriser les applications Chat SDK avec Access Manager. Ce service simule un point de terminaison simple et inclut un exemple d'ensemble de permissions que vous pouvez utiliser pour configurer l'autorisation côté serveur pour vos applications Chat SDK avec Access Manager activé.
Suivez l'ensemble du scénario de test en utilisant notre React Native Chat App (pour l'interaction avec les utilisateurs), Channel Monitor (pour la modération des utilisateurs, comme le muting et le bannissement), et Access Manager API (pour générer des jetons d'autorisation).
Pour les étapes détaillées, consultez le blog [Comment modérer en toute sécurité le chat et les utilisateurs avec BizOps Workspace](https://www.pubnub.com/how-to/securely-moderate-chat-and-users/?utm_source=devto&utm_medium=syndication&utm_campaign=off_domain&utm_content=fr).
Perspectives 📊
---------------
### Tableau de bord des mesures des appareils
**Type**: Amélioration
**Description**: Nous avons étendu le tableau de bord `Comportement de l'utilisateur` dans Insights pour inclure des [métriques de type d'appareil](https://pubnub.com/docs/pubnub-insights/dashboards/user-behavior). Cela vous permet de plonger en profondeur dans le comportement de vos utilisateurs par type d'appareil. Désormais, vous pouvez observer où les utilisateurs de votre application publient ou s'abonnent le plus souvent (iOS, Android et Windows) et vérifier le nombre d'utilisateurs uniques par type d'appareil.
Cet aperçu peut vous aider à créer des fonctionnalités personnalisées par appareil et, ainsi, à améliorer l'expérience client.
Événements et actions ⚡
-----------------------
### L'action Webhook prend désormais en charge la mise en lot
**Type**: Amélioration
**Description**: La fonctionnalité de [mise en lot](https://pubnub.com/docs/serverless/events-and-actions/events#batching) dans Events & Action vous permet de gérer un grand volume d'événements en les envoyant en une seule demande plutôt que d'envoyer chaque événement individuellement. Cette fonctionnalité est également disponible pour le type d'[action Webhook](https://pubnub.com/docs/serverless/events-and-actions/actions/create-webhook-action) depuis le mois de mai.
### (Non)enveloppant
**Type**: Amélioration
**Description**: Vous pouvez maintenant envelopper le payload de chaque action dans une [enveloppe](https://pubnub.com/docs/serverless/events-and-actions/events#envelope), c'est-à-dire choisir si le schéma du payload doit contenir des métadonnées JSON détaillées sur les événements et les actions. Cela peut être utile dans les cas où vous voulez utiliser des métadonnées en dehors du payload, comme des informations sur le canal où le payload a été envoyé ou l'auditeur qui l'a déclenché.
Illuminer 💡
------------
### Diagrammes à barres empilées
**Type**: Nouvelle fonctionnalité
**Description**: En plus des graphiques à barres et des graphiques linéaires, les tableaux de bord Illuminate proposent désormais un nouveau type de graphique [à barres empilées](https://pubnub.com/docs/illuminate/dashboards/basics#settings) qui améliore la lisibilité des données lorsqu'il y a de nombreuses dimensions et valeurs sur un seul graphique.
### Variables
**Type**: Amélioration
**Description**: Lorsque vous créez des actions dans Decisions (en indiquant ce que vous voulez faire avec les métriques collectées), vous pouvez ajouter des [variables](https://pubnub.com/docs/illuminate/decisions/basics#decision-structure) dans les tables de configuration des actions pour contrôler et modifier dynamiquement ce à quoi elles se réfèrent. Vous pouvez utiliser les variables de manière plus souple, soit en vous référant aux conditions prédéfinies (tapez `${)` et choisissez dans la liste), soit en créant de nouvelles variables`(${variable}`) au fur et à mesure. Les variables sont désormais disponibles pour la plupart des champs d'action, et non plus seulement dans la **charge utile** ou le **corps de** l'action.
### Champs de mappage de données améliorés
**Type**: Amélioration
**Description**: Lorsque vous créez un objet d'affaires et définissez des mesures (les données que vous voulez suivre) ou des dimensions (pour segmenter ce que vous suivez), vous devez mapper les noms de champs aux champs réels dans votre charge utile pour permettre à Illuminate de savoir où ces données doivent être recherchées. Jusqu'à présent, vous deviez entrer manuellement le mappage exact du champ spécifique de la charge utile. Depuis le mois de mai, Illuminate propose des [menus déroulants](https://pubnub.com/docs/illuminate/business-objects/basics#data-mapping) plus conviviaux pour localiser l'emplacement exact des données Publish et App Context.
Autres 🌟
---------
### Nouvel assistant de recherche et d'IA
**Type**: Nouvelle fonctionnalité
**Description**: Enfin, nous avons troqué la recherche Algolia dans nos documents pour la nouvelle expérience combinée de recherche et d'assistant IA afin de rendre l'aventure d'apprentissage de PubNub plus précise et interactive.
Il est temps d'améliorer votre jeu de codage et de vous faire des amis avec notre nouvel assistant IA et notre nouvelle fonction de recherche. Nous l'affinerons en fonction de vos commentaires, donc si quelque chose manque, nous nous assurerons de le mettre à jour. Bon codage ! 🚀 | pubnubdevrel |

1,915,668 | How to Use Terraform Providers | What are Terraform Providers A key feature of Terraform is the ability to manage... | 0 | 2024-07-08T12:30:00 | https://www.env0.com/blog/how-to-use-terraform-providers | terraform, devops, kubernetes, aws | What are Terraform Providers
----------------------------
A key feature of [Terraform](https://www.env0.com/blog/terraform-tutorial) is the ability to manage infrastructure on virtually any platform. But how does Terraform know how to interact with infrastructure services as diverse as AWS, Kubernetes, and GitHub? That's where Terraform providers step in. They are the superpower that lets Terraform deploy infrastructure to any cloud or service.
A Terraform provider plugin is an executable binary that implements the [Terraform plugin framework](https://developer.hashicorp.com/terraform/plugin/framework). It creates a layer of abstraction between the provider's upstream APIs and the constructs Terraform expects to work with.
Terraform core doesn't know how the provider APIs work, it only knows how to manage resources and data sources. A Terraform provider is responsible for understanding API interactions and translating exposing resources and data sources from a cloud provider like AWS to a framework Terraform understands.
A Terraform provider encapsulates authentication methods, resources supported, lifecycle management, and API calls. Without a rich provider ecosystem backed by a robust community, Terraform wouldn't be able to provision infrastructure or manage resources. Providers are pretty important!
**How to Install Terraform Providers**
--------------------------------------
The public [Terraform registry](https://www.env0.com/blog/terraform-registry-guide-tips-examples-and-best-practices) has thousands of published providers, including the most popular cloud providers. Each Terraform provider on the registry is open-source, free to use, and includes documentation for using the provider in your Terraform configurations. When adding a new Terraform provider to your code, you should define its properties in the `required_providers` block and then configure instances of the provider using `provider` blocks.
terraform {
required_providers {
azurerm = {
source = "hashicorp/azurerm"
version = "3.0.0"
}
}
}
provider "azurerm" {
features {}
}
Terraform will attempt to infer which providers are being used based on the resource types in your configuration, but explicitly defining providers gives you more control over the version and source being used.
Once you've added providers to your Terraform configuration file, the next step is to run [`terraform init`](https://www.env0.com/blog/terraform-init) which downloads and installs providers from the sources listed in the `required_providers` block.
> terraform init

Initializing provider plugins...
- Finding hashicorp/azurerm versions matching "3.0.0"...
- Installing hashicorp/azurerm v3.0.0...
- Installed hashicorp/azurerm v3.0.0 (signed by HashiCorp)
The Terraform providers are packaged as plugin binaries. They are downloaded and stored in the **.terraform/providers** directory in your current working directory.
Many providers require configuration before they can be used to manage resources. For instance, the AWS provider needs to know which AWS region you plan to provision resources in, and the Terraform Kubernetes provider needs to know the address of the Kubernetes cluster you'd like to connect to.
Provider configuration is defined in a `provider` block using the provider keyword and the name of the provider from the `required_providers` block. If you need to create more than one instance of a Terraform provider, you can do so using the `alias` argument inside of the `provider` block. For example, you may want to work with multiple regions in AWS:
provider "aws" {
region = "us-east-1"
}
provider "aws" {
alias = "west"
region = "us-west-1"
}
### **Few Things to Know**
With [thousands of providers available on the public Terraform registry](https://registry.terraform.io/browse/providers), you might wonder how to select the right Terraform provider for your use case. Providers on the registry have one of three designations:
1. **Official provider** – These providers are collaboratively maintained by a dedicated team at HashiCorp, usually with assistance from the service vendor or working group.
2. **Partner provider** – These providers are maintained by an organization that has completed the HashiCorp Technical Partner requirement.
3. **Community provider** – These providers are maintained by an individual or group of contributors.
Official and partner providers tend to have the most active community behind them, have a regular release cadence, and respond quickly to issues and requests. You can also view the popularity of a provider based on downloads, the most recent release, and the provider documentation from the provider overview page.
Because providers from the registry are open-source and hosted on GitHub, you can also view the source code for each provider, browse through its current issues, and read the release notes for each version to see whether to upgrade.
Providers on the public registry are versioned using the semantic versioning standard of **Major.Minor.Patch**. You can constrain the version being used by your configuration using the `version` argument in the `required_providers` block.
Newer versions of a Terraform provider will include new resources, additional arguments for existing resources, and bug fixes for issues. Major version updates may also include deprecated resource types, arguments, or other breaking changes.
Controlling the provider version gives you and your team a consistent experience when working on Terraform code. To make the version upgrade process more deliberate, HashiCorp introduced the Terraform dependency lock file.
The dependency lock file is created the first time `terraform init` is run against a Terraform configuration. It captures the current version of each Terraform provider being used and creates the file **.terraform.lock.hcl** in the configuration directory to capture that information.
provider "registry.terraform.io/hashicorp/azurerm" {
version = "3.77.0"
constraints = "~> 3.0"
hashes = [
"h1:7XzdPKIJoKazb3eMhQbjcVWRRu5RSsHeDNYUQW6zSAc=",
"zh:071c82025cda506af90302b3e89f61e086ad9e3b97b8c55382d5aed6f207cf10",
...
]
}
Also included in the file is the constraint for the provider version and a hash of the provider plugin executable.
Although all Terraform providers use the same Terraform plugin SDK to expose infrastructure resources and data sources from their upstream API, different providers have their own arguments and supported authentication methods. Let's review some of the most popular providers on the Terraform registry.
**What are the most popular Terraform providers?**
--------------------------------------------------
The most commonly used providers are listed on the main provider page of the Terraform public registry:
The following table shows the six most popular providers, their total downloads, and current version:
Each provider comes with documentation detailing the infrastructure resources and data sources contained within and how to configure and interact with the provider. Of particular note is the way in which each provider handles authentication to their service.
The three major cloud providers – AWS, Azure, and Google – each have multiple ways to authenticate depending on the client type and usage scenario.
For instance, the AWS provider supports authentication from environment variables, instance profiles, container credentials, and shared credential files. Before attempting to integrate a new provider into your configuration, be sure to read the documentation, especially the authentication section.
Some providers also handle preview, beta features, and services differently.
The Azure provider does not immediately support all functionality exposed by the Azure Resource Manager API (in particular for features and services that are in private or public preview). As a stopgap measure, the AzAPI provider is available, which is a thin layer of abstraction over the ARM API.
Likewise, the Google Cloud Platform provider does not support beta features and services on the platform. If you wish to use a beta feature, you can leverage the Google Beta instead.
Let's take a closer look at the most popular provider on the registry, the AWS provider.
**Example: Terraform AWS Provider**
-----------------------------------
Amazon Web Services (AWS) was the first external provider included in Terraform. It remains the most popular provider based on download metrics by a comfortable margin. Each instance of the AWS provider in a configuration is region-specific, and the region is set using either an argument in the provider configuration block or with the `AWS_REGION` environment variable.
provider "aws" {
region = "us-west-2"
}
When adding an AWS provider to your Terraform code, you need to determine how you'll authenticate to the platform. The most common method when running from a workstation is to use the Access Key and Secret Key stored in your AWS credentials file. Typically, this is generated using the AWS CLI command `configure`.
> aws configure
AWS Access Key ID: *********************
AWS Secret Access Key: ***********************
Default region name: us-west-2
Default output format: json
The configure command will create or update the default profile stored in your credentials file. The AWS provider will use the default profile if no other authentication methods are configured.
You can work with multiple AWS accounts in your configuration by adding additional provider configuration blocks with the `alias` meta-argument. If you have a cross-account role to assume, that can be configured use the `assume_role` argument.
provider "aws" {
alias = "shared"
assume_role = "shared-ec2-admin"
}
**Final Thoughts**
------------------
Terraform providers are essential to the functionality of Terraform. Without provider plugins, Terraform wouldn't be able to provision and manage infrastructure! A large part of Terraform's success is owed to the vast collection of Official, Partner, and Community providers backed by vibrant and active groups of maintainers.
Terraform providers published on the public registry are all open-source and hosted on GitHub. Because the provider schema is well-documented, Terraform providers are not necessarily limited to only being consumed by Terraform.
[OpenTofu](https://www.env0.com/blog/opentofu-alpha-launches-try-it-out-in-just-3-clicks), an open-source alternative to Terraform, works perfectly with the existing Terraform providers. [Pulumi](https://www.env0.com/blog/what-is-pulumi-and-how-to-use-it-with-env0), an infrastructure management tool leveraging general-purpose programming languages, also uses Terraform providers when a native provider for the platform is not available. | env0team |

I was curious when I was constantly getting notifications that NVIDIA stocks were high, but I didn't pay attention to it for a very long time (I knew subconsciously it had something to do with chip making. That's it.).
Finally, when I did that, I learned about GPGPU. And I shared my findings with you guys in the last article I wrote.
[Harnessing GPU Power for General-Purpose Computing](https://dev.to/rajai_kumar/gpgpu-harnessing-gpu-power-for-general-purpose-computing-pc7)
While I was doing my weekend's mundane, purposeless reading, I found this page on Apple.
[Apple - Metal: Computations on GPU](https://developer.apple.com/documentation/metal/performing_calculations_on_a_gpu)
Interesting huh? I will give a simplified version of the above.
## Performing Calculations on a GPU with Metal
> Essentially, you get the GPU device through Metal, send the data to it, get it processed with the code you have written in MSL, and get the result.
Now let's get to the interesting part. I wanted to see how much of a difference this process actually makes. Keep in mind that there is processing involved in getting the data into the GPU and getting the result out.
I used the example provided by Apple but changed the operation it had. I felt it was too simple, so I changed it.
## From
```
result[index] = inA[index] + inB[index];
```
## To
```
float dotProduct = inA[index] * inB[index];
result[index] = 1.0 / (1.0 + exp(-dotProduct));
```
### I made a graph using Claude to visually show the complexity.
And instead of just checking results from the GPU using the for loop, I used DispatchQueue to process the same data to compare CPU and GPU performance. For that, I recorded the start time and end time to get the elapsed time for both.
### Using the DispatchQueue
```
- (void) usingDispatchQueue
{
float* a = _mBufferA.contents;
float* b = _mBufferB.contents;
uint64_t start = mach_absolute_time();
dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_apply(arrayLength, queue, ^(size_t index) {
// Compute the expected dot product
float dotProduct = a[index] * b[index];
// Apply the sigmoid function to the dot product
float expected = 1.0 / (1.0 + exp(-dotProduct));
//printf("Expected: %f \n", expected);
});
uint64_t end = mach_absolute_time();
uint64_t elapsed = end - start;
mach_timebase_info_data_t info;
mach_timebase_info(&info);
double elapsedNano = (double)elapsed * (double)info.numer / (double)info.denom;
printf("Time taken - DispatchQueue: %f nanoseconds\n", elapsedNano);
}
```
### Below here is the result.
### So, now I know why NVIDIA stocks are high.
If you guys have any suggestions about the way I did the comparison, please let me know. I am new to this topic.
You will find the code for the experiment in the link below

1,915,676 | AI Drive-Thru Hits a Speed Bump: McDonald's Pauses Voice Ordering Tech | For McDonald's, the name synonymous with convenience, their quest to expedite the ordering process... | 0 | 2024-07-08T11:39:44 | https://dev.to/hyscaler/ai-drive-thru-hits-a-speed-bump-mcdonalds-pauses-voice-ordering-tech-3de5 | For McDonald's, the name synonymous with convenience, their quest to expedite the ordering process through AI-powered drive-thrus has encountered a temporary detour. Their experiment with voice-enabled AI systems at 100 US locations has been halted, sparking questions about the technology's future within the fast-food landscape.
This decision follows a trial period with mixed results. Partnering with IBM, McDonald's developed "Automated Order Taking" (AOT) technology aimed at enhancing customer experience and crew efficiency. However, some customers encountered accuracy issues with their orders.
## Why Did McDonald's Pull the Plug on AI Drive-Thru Ordering?
The primary culprit behind McDonald's pausing its [AI drive-thru](https://hyscaler.com/insights/mcdonald-ai-drive-thru-on-hold/) ordering is accuracy. Customers reported instances where the AI system struggled to decipher their orders due to factors like regional accents or background noise. These misinterpretations resulted in frustrated customers receiving incorrect items, exposing the limitations of the current technology.

1,915,683 | I will tell you my journey, maybe intresting! | Ehy everyone 👋 is Antonio, CEO at Litlyx. I thought it would be interesting to share my background,... | 0 | 2024-07-08T11:44:12 | https://dev.to/litlyx/i-will-tell-you-my-journey-maybe-intresting-4gii | discuss | Ehy everyone 👋 is Antonio, CEO at [Litlyx](https://litlyx.com).
I thought it would be interesting to share my **background**, my **wins**, and my **failures** in a post on dev.
## The Origin
When I was **7 years old**, I really wanted to play video games, but my family couldn't afford a PlayStation or Gameboy. My dad had a computer for work, and when he wasn't using it, I would sneak in and use it to browse the internet. I did a lot of silly things back then, and I remember my mom yelling at me because the only way to connect was to attach the house phone's ethernet cable to the PC. By the time I was 10, I had figured out how to download game ROMs.
## The Trauma
**At 15-16,** my phone got infected with a virus, and we were blackmailed badly. I promised myself I wouldn't be targeted by malicious hackers again and quickly dove into OSINT and Cyber Security. Within a couple of years, I was using an old PC with a virtual machine running Kali Linux, trying to track down malicious hackers for payback. Spoiler: I never found any and eventually gave up.
## The Realization
**Around 17-18,** I realized I had a deep love for technology, especially Python and C#. I was a nerd who loved playing video games and decided I wanted to create them. I started learning Unity and, after 1-2 years, switched to Unreal Engine, moving from C# to C++ and dealing with "spaghetti code."
## The First job
**19 years old. **My first job was unpaid, with poor working conditions, at a video game software house in Italy. It was rough, so I decided to switch and become a Mobile Developer.
## The Innovative Ecosystem
**At 21,** I entered the startup ecosystem with an internship at an accelerated startup. It was full of unforgettable lessons. I learned Java and later switched to Flutter. Along with changing programming languages, I changed jobs. I worked at a small, scaling startup for 16 hours a day with promised stocks that never materialized. Fortunately, I left before they failed miserably.
## The Mental Breakdown
All that pressure from endless working hours took its toll. I had a mental breakdown **at 26** and stopped everything for six months. I went to a psychologist, who helped me overcome that dark period.
## The New Vital Strength
After recovering, I launched seven SaaS projects. Six failed, but one succeeded and is now a leader in a specific market in Italy. With renewed energy, I'm currently launching my SaaS on Analytics, [Litlyx](https://litlyx.com), That is an [Open-Source](https://github.com/Litlyx/litlyx) alternative to Google Analytics. but with much more to offer. **Now i'm 28 years old!**
I hope you enjoyed my story. I aimed to keep it simple and easy to follow, though there was much more to it. Please share some love in the comments.
And PLEASE!! Leave us a star on [Github](https://github.com/Litlyx/litlyx) you will help us a lot!
Peace,
Antonio

</>
)
}
export default Test
```
##Props
**_options_**(array,required when `api` prop is not provided )
- Description: An array of pre-defined options to be used instead of fetching data from an API.This can be particularly useful for small dataset, static datasets or for data that is already available on the client side.
- Example :
- Simple linear array - [ "Item 1", "Item 2", "Item 3", // ...more items],
- Array of objects - [ { id: 1, name: "Item 1" }, { id: 2, name: "Item 2" }, // ...more items ]
**_pageSize_**(number,default:50) :
- The number of items to show and fetch(in-case of fetching data) per page.
**_isLinearArray_**(boolean,default:false) :
- Set {true} when :
- The fetched data or value of `options` prop is a simple linear array of primitive values (e.g., strings, numbers).
- No `displayKey` is needed.
- Example: ["item1", "item2", "item3"]
- Set {false} when:
- The fetched data or value of `options` prop is an array of objects.
- A `displayKey` must be specified to indicate which property to display.
c. Example:
```json
[
{"name": "id labore ex et quam laborum","email": "Eliseo@gardner.biz",},
{"name": "quo vero reiciendis velit similique earum","email": "Jayne_Kuhic@sydney.com"},
]
```
- In this case, set `displayKey` to the property you want to display, e.g., "email".
**_displayKey_**(string,default:'name',required only when `isLinearArray` is false) :
- Description : Specifies the property of the objects in the array to be displayed.
For instance, consider the following response from an API:
```json
[
{"name": "id labore ex et quam laborum","email": "Eliseo@gardner.biz",},
{"name": "quo vero reiciendis velit similique earum","email": "Jayne_Kuhic@sydney.com"},
]
```
- To display the "email" field, set `displayKey` to "email".
**_api_**(object,required when `options` prop is not provided) :
- Properties :
- **resourceUrl** (string, required):
- The URL from which data will be fetched.
- **pageParamKey** (string, optional, default: "_page") :
- This is the query parameter key used by your backend API to specify the page number. It should match what your backend expects for pagination.Common defaults include "page", "pageNumber", "p".

After all, life’s too short to spend it all behind a screen.
### Isolation 😑 Factor
While programming offers the freedom to work remotely and independently, it can also lead to isolation. Spending long hours in front of a computer screen and troubleshooting code solo can sometimes lead to loneliness. Without the colleagues of a traditional office environment, programmers may miss out on all the social interactions and spontaneous collaborations that can spark creativity and association.
However, this isolation can be a welcome aspect of the job for people who blossom in solitary environments, allowing them to focus deeply on their work without distractions. Ultimately, whether isolation in programming is seen as good or bad depends on individual preferences and working styles. Some may find comfort in solitude, while others may desire more social interaction.
It’s completely up to you where to place it, on the pros or cons list. In the end, it’s a reflection of your character. ☔ 🌈 🌞
### Imposter 😰 Syndrome Warning
Huh, this awful self-doubt phenomenon. Imposter syndrome is common among programmers, where skilled developers feel inadequate and fear being revealed as frauds despite their abilities. This lack of self-confidence can prevent their professional growth by discouraging them from participating in projects, speaking at conferences, or applying for advanced roles.
Always remember that you won’t know if you can do it, unless you try. So, do not hesitate! Take the shot! 🥁
### Burnout 😵💫
Last but not least – burnout. Arising from long stress and imbalance between work and personal life. Symptoms include exhaustion and reduced productivity, which can lead to physical health issues and mental health problems like depression.
We can prevent this by setting boundaries, organizing workloads, discussing it with our colleagues, asking for support, and taking breaks. Loong ☕ loong 💤 breaks! These techniques will help to maintain health and sustain enthusiasm for coding.
Are all part of the journey. So, roll up your sleeves and dive into work. But always remember that burnout is not an option. Get out of your computer when you need a break!!
So, go ahead! Begin this programming journey and picture yourself as our courageous astronaut exploring new boundaries. Equipped with the tools of the trade—a laptop, determination, and a thirst for discovery. Whether you’re dreaming of distant 🌌 galaxies or lines of 📜 code, remember: this path is one of endless possibilities.
So, what are you waiting for? Embark on your own adventure.
Conquer the skies of coding!
Bon voyage! 🪐 ✨

This stage brought on a task that at first glance seems easy and straightforward, but when the added requirements were introduced, the complexity grew and the challenge became harder. The task instructs us to containerize a three tier application on a single server and use a proxy manager like nginx to configure reverse proxying to ensure the frontend and backend can be served from the same port. That's not all. It gets more complex.
Here are the full requirements for completing this tasks:
- Ensure the application runs locally before writing Dockerfiles
- Configure the Frontend and Backend to listen on port 80
- Obtain a domain name for the project
- Write Dockerfiles to containerize the frontend and backend
- Install adminer to enable database manager through its GUI
- Configure Nginx proxy manager to handle reverse proxying and setup SSL certificates
Let's get started
### Prerequisites
- A virtual machine running Ubuntu
- Basic Level Understanding of the Linux CLI
#### Step 1
**Clone the repo**
First we have to clone the [repository](https://github.com/hngprojects/devops-stage-2) from Github
```javascript
git clone https://github.com/hngprojects/devops-stage-2
cd devops-stage-2
```
#### Step 2
***Configure the backend***
The frontend of this application depends on the backend for full functionality so we will begin by configuring the backend.
```javascript
cd backend
```
**Dependencies**
The backend depends on a `postgresQL` database, It would also require `poetry` to be installed before starting up
##### Installing Poetry
To install Poetry, follow these steps:
```javascript
curl -sSL https://install.python-poetry.org | python3 -
```
Add Poetry to your PATH if it's not automatically added:
```javascript
# Example for Bash shell
export PATH="$HOME/.poetry/bin:$PATH" >> ~/.bashrc
source ~./bashrc
poetry --version
```
Replace $HOME/.poetry/bin with the appropriate path where Poetry binaries are installed if different on your system. This ensures you can run Poetry commands from any directory in your terminal session.
Install dependencies using Poetry:
```javascript
poetry install
```
Setup PostgreSQL:
Follow these steps to install PostgreSQL on Linux and configure a user named app with password my_password and a database named app. Give all permissions of the app database to the app user.
Install PostgreSQL on Linux (example for Ubuntu):
```javascript
sudo apt update
sudo apt install postgresql postgresql-contrib
```
Switch to the PostgreSQL user and access the PostgreSQL
```javascript
sudo -i -u postgres
psql
```
Create a user app with password my_password:
```javascript
CREATE USER app WITH PASSWORD 'my_password';
```
Create a database named app and grant all privileges to the app user:
```javascript
CREATE DATABASE app;
\c app
GRANT ALL PRIVILEGES ON DATABASE app TO app;
GRANT ALL PRIVILEGES ON SCHEMA public TO app;
```
Exit the PostgreSQL shell and switch back to your regular user.
```javascript
\q
exit
```
Set database credentials
Edit the PostgreSQL environment variables located in the .env file. Make sure the credentials match the database credentials you just created.
```javascript
---
POSTGRES_SERVER=localhost
POSTGRES_PORT=5432
POSTGRES_DB=app
POSTGRES_USER=app
POSTGRES_PASSWORD=my_password
```
Set up the database with the necessary tables:
```javascript
poetry run bash ./prestart.sh
```
Run the backend server and make it accessible on all network interfaces:
```javascript
poetry run uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload
```
#### Step 3
***Configure the frontend***
Open up a new terminal.
P.S. We can split the terminal session using [tmux](https://github.com/tmux/tmux/wiki) or run it as a system service, but to keep things fairly simple, we would leave the backend running in one terminal and open another terminal for the frontend.
```javascript
cd devops-stage-2/frontend
```
**Dependencies**
The frontend was built with `Nodejs` and `npm` for dependency management.
```javascript
sudo apt update
sudo apt install nodejs npm
```
Install dependencies:
```javascript
npm install
```
Run the fronted server and make it accessible from all network interfaces:
```javascript
npm run dev -- --host
```
Accessing the application using curl:
```javascript
curl localhost:5173
```
#### Step 4
**Accessing the UI**
Open your browser and navigate to:
```javascript
http://<your_server_IP>:5173
```
Enable login access from the UI:
The login credentials can be found in the .env located in the backend folder
```javascript
---
FIRST_SUPERUSER=devops@hng.tech
FIRST_SUPERUSER_PASSWORD=devops#HNG11
```
If we try login in now we would be met with a network error.
Looking through the developer tools we can see that connecting to the backend on `http://localhost:8000` was refused. This is because we are using a remote server and `localhost` in our browser's context means our personal computer. So to properly route the browser to the remote server running the application. we will have to Change the VITE_API_URL variable in the frontend .env file:
```javascript
VITE_API_URL=http://<your_server_IP>:8000
```
If we try to login now we are met with a new error called `CORS` which stands for Cross-origin resource sharing.
Basically, our backend doesn't recognise the origin of the request which is coming from our server's IP, so we need to tell our backend to accept request coming from that particular IP address.
In our backed .env file we need to add `http://<your_server_IP>:5173` to the end of the string of allowed IPs
```javascript
BACKEND_CORS_ORIGINS="http://localhost,http://localhost:5173,https://localhost,https://localhost:5173,http://<your_server_IP>:5173"
```
Now If we try one more time to login.
We successfully setup the application locally.
We can also access the swagger API as well as the documentation paths using `http://<your_server_IP>:8000/doc` and `http://<your_server_IP>:8000/redoc` respectively.
#### Step 5
**Containerizing the application**
Now we need to repeat the entire process, but this time, We would utilize Docker containers. we will start by writing Dockerfiles for both frontend and backend and then move to the project's root directory and configure a docker compose file that will run and configure:
- The Frontend and Backend
- The postgres database the backend depends on
- Adminer
- Nginx proxy Manager
Let's start by writing the Dockerfile for the backend application
```javascript
cd devops-stage-2/backend
vim Dockerfile
```
```javascript
# Use the latest official Python image as a base
FROM python:latest
# Install Node.js and npm
RUN apt-get update && apt-get install -y \
nodejs \
npm
# Install Poetry using pip
RUN pip install poetry
# Set the working directory
WORKDIR /app
# Copy the application files
COPY . .
# Install dependencies using Poetry
RUN poetry install
# Expose the port FastAPI runs on
EXPOSE 8000
# Run the prestart script and start the server
CMD ["sh", "-c", "poetry run bash ./prestart.sh && poetry run uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload"]
```
This repeats the entire process we carried out locally all in one file.
Now let's set up the frontend.
```javascript
cd devops-stage-2/frontend
vim Dockerfile
```
```javascript
# Use the latest official Node.js image as a base
FROM node:latest
# Set the working directory
WORKDIR /app
# Copy the application files
COPY . .
# Install dependencies
RUN npm install
# Expose the port the development server runs on
EXPOSE 5173
# Run the development server
CMD ["npm", "run", "dev", "--", "--host"]
```
Again, this simply repeats the process we carried out to run the frontend locally.
#### Step 6
**Docker compose setup**
Navigate to the project root directory and create a `docker-compose.yml` file
```javascript
cd devops-stage-2/
vim docker-compose.yml
```
Copy this configuration into it
```javascript
version: '3.8'
services:
backend:
build:
context: ./backend
container_name: fastapi_app
ports:
- "8000:8000"
depends_on:
- db
env_file:
- ./backend/.env
frontend:
build:
context: ./frontend
container_name: nodejs_app
ports:
- "5173:5173"
env_file:
- ./frontend/.env
db:
image: postgres:latest
container_name: postgres_db
ports:
- "5432:5432"
volumes:
- postgres_data:/var/lib/postgresql/data
env_file:
- ./backend/.env
adminer:
image: adminer
container_name: adminer
ports:

- "81:81"
environment:
DB_SQLITE_FILE: "/data/database.sqlite"
volumes:
- ./data:/data
- ./letsencrypt:/etc/letsencrypt
depends_on:
- db
- backend
- frontend
- adminer
volumes:
postgres_data:
data:
letsencrypt:
```
**Breakdown of the docker-compose.yml File**
Here's an explanation of each section in the provided docker-compose.yml file:
##### Services
Services are the containers that make up the application. Each service runs one image and can define volumes and networks. Each container can connect to any container in the same network using the service name.
**Backend Service**
```javascript
backend:
build:
context: ./backend
container_name: fastapi_app
ports:
- "8000:8000"
depends_on:
- db
environment:
POSTGRES_SERVER: ${POSTGRES_SERVER}
POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
```
- build.context: Specifies the build context, pointing to the ./backend directory which contains the Dockerfile for building the FastAPI backend service.
- container_name: Sets the container name to fastapi_app.
- ports: Maps port 8000 on the host to port 8000 in the container.
- depends_on: Ensures the db service is started before the backend service.
- environment: Injects environment variables from the .env file, used by the FastAPI application to connect to the PostgreSQL database.
**Frontend Service**
```javascript
frontend:
build:
context: ./frontend
container_name: nodejs_app
ports:
- "5173:5173"
environment:
VITE_API_URL: ${VITE_API_URL}
```
- build.context: Points to the ./frontend directory for building the Node.js frontend service.
- container_name: Names the container nodejs_app.
- ports: Maps port 5173 on the host to port 5173 in the container.
- environment: Injects the VITE_API_URL environment variable from the .env file, used by the frontend application to connect to the backend API.
**Database Service**
```javascript
db:
image: postgres:latest
container_name: postgres_db
ports:
- "5432:5432"
volumes:
- postgres_data:/var/lib/postgresql/data
environment:
POSTGRES_USER: ${POSTGRES_USER}
POSTGRES_PASSWORD: ${POSTGRES_PASSWORD}
POSTGRES_DB: ${POSTGRES_DB}
```
- image: Uses the latest PostgreSQL image from Docker Hub.
- container_name: Names the container postgres_db.
- ports: Maps port 5432 on the host to port 5432 in the container, which is the default port for PostgreSQL.
- volumes: Mounts a Docker volume postgres_data to persist database data.
- environment: Sets database-related environment variables from the .env file for initializing PostgreSQL.
**Adminer Service**
```javascript
adminer:
image: adminer
container_name: adminer
ports:
- "8080:8080"
```
- image: Uses the Adminer image, a database management tool.
- container_name: Names the container adminer.
- ports: Maps port 8080 on the host to port 8080 in the container for accessing the Adminer web interface.
**Proxy Service**
```javascript
proxy:
image: jc21/nginx-proxy-manager:latest
container_name: nginx_proxy_manager
ports:
- "80:80"
- "443:443"
- "81:81"
environment:
DB_SQLITE_FILE: "/data/database.sqlite"
volumes:
- ./data:/data
- ./letsencrypt:/etc/letsencrypt
depends_on:
- db
- backend
- frontend
- adminer
```
- image: Uses the latest Nginx Proxy Manager image.
- container_name: Names the container nginx_proxy_manager.
- ports: Maps ports 80, 443, and 81 on the host to the same ports in the container for HTTP, HTTPS, and the Nginx Proxy Manager admin interface.
- environment: Sets the environment variable for the SQLite database location.
- volumes: Mounts the data directory for storing proxy manager data and the letsencrypt directory for SSL certificates.
- depends_on: Ensures the db, backend, frontend, and adminer services are started before the proxy service.
**Volumes**
```javascript
volumes:
postgres_data:
data:
letsencrypt:
```
Defines named volumes to persist data across container restarts.
#### Step 7
**Domain Setup**
We need to setup domains and subdomains for the frontend, adminer service and Nginx proxy manager.
Remember we are required to route port 80 to both frontend and backend:
- domain - Frontend
- domain/api - Backend
- db.domain - Adminer
- proxy.domain - Nginx proxy manager
If you don't have a Domain name, you can acquire a subdomain at [AfraidDNS](https://freedns.afraid.org/). That's where i acquired the domain I used for this project. Ensure you route all the required domains above to the server your application is running on.
#### Step 8
**Routing domains using Nginx proxy manager**
We now have everything set up, we can run `docker-compose up -d` to get our application up and running. We would need to install Docker and Docker-compose first.
Install Docker
Update the package list:
```javascript
sudo apt-get update
```
Install required packages:
```javascript
sudo apt-get install \
apt-transport-https \
ca-certificates \
curl \
software-properties-common
```
Add Docker’s official GPG key:
```javascript
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
```
Add the Docker repository to APT sources:
```javascript
sudo add-apt-repository \
"deb [arch=amd64] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) \
stable"
```
Update the package list again:
```javascript
sudo apt-get update
```
Install Docker:
```javascript
sudo apt-get install docker-ce
```
Verify that Docker is installed correctly:
```javascript
sudo systemctl status docker
```
Install Docker Compose
Download the latest version of Docker Compose:
```javascript
sudo curl -L "https://github.com/docker/compose/releases/download/$(curl -s https://api.github.com/repos/docker/compose/releases/latest | grep -oP '"tag_name": "\K(.*)(?=")')" /usr/local/bin/docker-compose
```
Apply executable permissions to the binary:
```javascript
sudo chmod +x /usr/local/bin/docker-compose
```
Verify that Docker Compose is installed correctly:
```javascript
docker-compose --version
```
Post-Installation Steps for Docker
Manage Docker as a non-root user:
Create the docker group if it doesn't already exist:
```javascript
sudo groupadd docker
```
Add your user to the docker group:
```javascript
sudo usermod -aG docker $USER
```
Now we can start up the application.
Ensure you are in the project root directory
```javascript
cd devops-stage-2
```
Start the application
```javascript
docker-compose up -d
```
If you get a permission denied error, run is as superuser
```javascript
sudo docker-compose up -d
```
Running `curl localhost` gives us a HTML response that Nginx proxy manager is successfully installed
#### Step 9
**Reverse Proxying and SSL setup with Nginx proxy manager**
Access the Proxy manager UI by entering http://<your_server_IP>:81 in your browser, Ensure that port is open in your security group or firewall.
Login with the default Admin credentials
- Email: admin@example.com
- Password: changeme
Click on Proxy host and setup the proxy for your frontend and backend
Map your domain name to the service name of your frontend and the port the container is listening on Internally.
Click on the SSL tab and request a new certificate
Now to configure the frontend to route api requests to the backend on the same domain, Click on Advanced and paste this configuration
```javascript
location /api {
proxy_pass http://backend:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /docs {
proxy_pass http://backend:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
location /redoc {
proxy_pass http://backend:8000;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;
}
```
Repeat the same process for
- db.domain: to route to your adminer service on port 8080
- proxy.domain: to route to the proxy service UI on port 81
You don't need to do the advanced setup on the db and proxy domain
#### Step 10
**Setup Adminer**
Access the adminer web interface on `db.<your_domain>.com`
Login with the db credentials in your backend .env file
#### Step 11
**Setup Frontend Login**
Access your frontend on `<your_domain>`
Before you login, make sure to change change the API_URL in your frontend .env to the name of your domain
```javascript
VITE_API_URL=https://<your_domain>
```
You would need to run `docker-compose up -d --build` to enable the changes to take effect
Your login should be successful now
#### Conclusion
We have now successfully:
- Configured and tested the full stack application locally
- Containerized the application
- Setup Docker compose
- Configured Adminer for Database management
- Configured Reverse Proxying with Nginx Proxy Manager
- Setup SSL certificates for our domains

1,915,687 | Explore how BitPower Loop works | BitPower Loop is a decentralized lending platform based on blockchain technology that aims to provide... | 0 | 2024-07-08T11:46:43 | https://dev.to/asfg_f674197abb5d7428062d/explore-how-bitpower-loop-works-3bjk | BitPower Loop is a decentralized lending platform based on blockchain technology that aims to provide secure, efficient and transparent lending services. Here is how it works in detail:
1️⃣ Smart Contract Guarantee
BitPower Loop uses smart contract technology to automatically execute all lending transactions. This automated execution eliminates the possibility of human intervention and ensures the security and transparency of transactions. All transaction records are immutable and publicly available on the blockchain.
2️⃣ Decentralized Lending
On the BitPower Loop platform, borrowers and suppliers borrow directly through smart contracts without relying on traditional financial intermediaries. This decentralized lending model reduces transaction costs and provides participants with greater autonomy and flexibility.
3️⃣ Funding Pool Mechanism
Suppliers deposit their crypto assets into BitPower Loop's funding pool to provide liquidity for lending activities. Borrowers borrow the required assets from the funding pool by providing collateral (such as cryptocurrency). The funding pool mechanism improves liquidity and makes the borrowing and repayment process more flexible and efficient. Suppliers can withdraw assets at any time without waiting for the loan to expire, which makes the liquidity of BitPower Loop contracts much higher than peer-to-peer counterparts.
4️⃣ Dynamic interest rates
The interest rates of the BitPower Loop platform are dynamically adjusted according to market supply and demand. Smart contracts automatically adjust interest rates according to current market conditions to ensure the fairness and efficiency of the lending market. All interest rate calculation processes are open and transparent, ensuring the fairness and reliability of transactions.
5️⃣ Secure asset collateral
Borrowers can choose to provide crypto assets as collateral. These collaterals not only reduce loan risks, but also provide borrowers with higher loan amounts and lower interest rates. If the value of the borrower's collateral is lower than the liquidation threshold, the smart contract will automatically trigger liquidation to protect the security of the fund pool.
6️⃣ Global services
Based on blockchain technology, BitPower Loop can provide lending services to users around the world without geographical restrictions. All transactions on the platform are conducted through blockchain, ensuring that participants around the world can enjoy convenient and secure lending services.
7️⃣ Fast Approval and Efficient Management
The loan application process has been simplified and automatically reviewed by smart contracts, without the need for tedious manual approval. This greatly improves the efficiency of borrowing, allowing users to obtain the funds they need faster. All management operations are also automatically executed through smart contracts, ensuring the efficient operation of the platform.
Summary
BitPower Loop provides a safe, efficient and transparent lending platform through its smart contract technology, decentralized lending model, dynamic interest rate mechanism and global services, providing users with flexible asset management and lending solutions.

1,915,690 | Android for Privacy | Introduction Kind of guide to my-self to install and configure my de-googled cellphone. Android... | 0 | 2024-07-08T11:47:47 | https://dev.to/rafaone/android-for-privacy-af1 | privacy, degoogle, android, tracker | **Introduction**
Kind of guide to my-self to install and configure my de-googled cellphone.
Android provided by brands has totally googled eco-system, that force you to use the big-tech services, and blind you in terms of trade off about your privacy and the free services.
**Alternatives OS**
To bypass this we have a some alternatives in terms of Operation System for android, I tested LinageOS, CalyxOS, because they have support for my currently hardware, you can consider GrapheneOS and DivestOS. On of advantage is that you can update your phone to newest android(14).
Considering that you are getting a pure S.O with minimal to start to install the Apps that will attend you with functionality versus privacy.
Many ways to follow, because of this I'm writing to my self back and re-learn with my chooses.
**Apps that track info from you**
My approach is avoid at all big-tech services, and replace for community options, to this you will need spirit of auto custody.
And take care about you backups, e-mail, calendar, contacts etc.
Transitory time is acceptable to use some tracked apps, but important to you know how to check that and decide considering the risks.
The most popular way is use Exodus Privacy reports to verify this info, basically the web site tell you how many "tracks" the app has, and track means a inside codes in app that collect data from you.
[Twitter/X](https://reports.exodus-privacy.eu.org/en/reports/com.twitter.android/latest/) has 4 tracks and you check will have information about the data that are collect from you.
It's a pain in the ass verify and decide, much time to test and consider witch app you will use.
**Apps**
List of Alternatives [Awesome-Privacy](https://github.com/pluja/awesome-privacy) and [DeGoogle](https://github.com/tycrek/degoogle)
The first app to use is F-Droid, unpopular store no need google account basically is a repository that you can trust more than download the apk from another sources.
I recommend to install Aurora Store, this one "need" google account that you can choose anonymous one and its connected with PlayStore but has linked report with Exodus Services than is easy to check if the app has trackers.
**Store**: F-Droid, Aurora Store
**Home**: TCP/UDP WIDGET (developed by KJM), Ewlink
**Sec**: Aegis Authentication, OpenKeyChain.
**Chat**: Telegram Foss, Signal, SimpleX, Proton-Mail.
**Browser**: Mull, Firefox.
**Social**: Amethyst nostr Client.
**Media**: Spotube, Tubular, LibreTube, Materialious, FocusPodcast.
**Maps**: OsmAnd, GMaps WV.
**Others**: Material Files, ConnectBot
**VPN/Firewall**: Orbot, Wireguard Client, NetGuard.
[Exodus Reports](https://reports.exodus-privacy.eu.org) are amazing to help you to decide, if you really need install an app or not, sometimes is better to use the service in the web-browser to avoid tracks, sure that on web-site they can collect data, but you can use Firefox extension like uBlock Origin and Privacy Badger that will mitigate that and block the track .
Your Firefox/based Firefox browser is a good option, you need to configure and remove the telemetry about mozilla, but is easy to do this, the extension to improve the privacy are enough.
**Conclusion**
Nowadays we good services for privacy approach like Proton services, Next-Cloud etc, the best option is your auto custody of your data creating your setup, has more work to do, but has more privacy.

1,915,691 | From Monolith to Microservices: A Practical Guide for Web Developers | Transitioning from a monolithic architecture to microservices is a significant but rewarding... | 0 | 2024-07-08T11:47:54 | https://dev.to/klimd1389/from-monolith-to-microservices-a-practical-guide-for-web-developers-58o3 | webdev, discuss, microservices, programming | Transitioning from a monolithic architecture to microservices is a significant but rewarding challenge for web developers. This guide will walk you through the key concepts, benefits, and steps involved in making this transformation.
Understanding the Basics
Monolithic Architecture
A monolithic architecture is a traditional model where all the components of an application are interwoven into a single, cohesive unit. This can be easier to develop initially but can lead to challenges in scaling, maintaining, and deploying applications as they grow.
Microservices Architecture
Microservices architecture breaks down an application into smaller, independent services. Each service is responsible for a specific functionality and can be developed, deployed, and scaled independently. This architecture is designed to improve scalability, flexibility, and speed of development.
Benefits of Microservices
Scalability: Each service can be scaled independently based on its demand.
Flexibility: Different services can be developed using different technologies that best suit their functionality.
Resilience: Failure in one service does not necessarily impact others.
Faster Deployments: Smaller, independent services can be deployed more frequently.
Improved Maintainability: Easier to manage and update smaller codebases.
Steps to Transition
Assess Your Monolith
Before breaking down your monolithic application, understand its architecture, dependencies, and pain points. Identify the modules that can be isolated as independent services.
Design Your Microservices
Design your microservices with clear boundaries and responsibilities. Ensure each service is loosely coupled and has a single responsibility.
Choose the Right Tools and Technologies
Please select the right tools and technologies for communication between services, data management, and monitoring. Common choices include:
APIs: REST or gRPC for communication
Data Management: Each service should manage its own database
Service Discovery: Tools like Consul or Eureka
Monitoring: Tools like Prometheus and Grafana
Start Small
You can start with a single module or feature that is relatively easy to extract. This will help you understand the process and challenges involved.
Implement Inter-Service Communication
Establish reliable communication between services. Use synchronous communication (HTTP/REST) or asynchronous communication (message queues like RabbitMQ or Kafka) based on your needs.
Data Management Strategy
Decide how data will be managed across services. Implement strategies like Database per Service and ensure data consistency through event sourcing or distributed transactions if needed.
Testing
Thoroughly test each microservice independently and as part of the entire system. Implement unit tests, integration tests, and end-to-end tests to ensure reliability.
Deployment
Deploy your microservices using containerization tools like Docker and orchestration tools like Kubernetes. This ensures consistent environments and simplifies scaling.
Monitoring and Maintenance
Implement robust monitoring and logging to track the health and performance of your services. Use tools like ELK Stack (Elasticsearch, Logstash, Kibana) for centralized logging and monitoring.
Common Challenges
Increased Complexity: Managing multiple services can increase operational complexity.
Data Consistency: Ensuring data consistency across services can be challenging.
Inter-Service Communication: Network latency and service failures need to be handled gracefully.
Deployment Overhead: More services mean more deployment artifacts to manage.
Conclusion
Transitioning from a monolithic to a microservices architecture can significantly enhance the scalability, flexibility, and maintainability of your applications. However, it requires careful planning, a clear understanding of your application's architecture, and a solid strategy for managing the increased complexity. By following the steps outlined in this guide, you can navigate the challenges and reap the benefits of microservices.
Embarking on this journey is not without its hurdles, but the potential rewards make it worthwhile for many web developers looking to build resilient and scalable applications.

1,915,692 | Python |  and methods (behaviors) that objects of that class will possess. Think of them as blueprints for houses: you define the rooms (properties) and what happens in those rooms (methods), and then you can create multiple houses (objects) based on that blueprint.
**Real-World Use Case:** Imagine a `Customer` class. It would have properties like `Name`, `Address`, and `Email`, and methods like `PlaceOrder` and `UpdateProfile`. Each `Customer` object would then hold specific information for a particular customer.
**When to Choose a Class:**
* When you need inheritance – classes can inherit properties and methods from other classes, promoting code reuse.
* When you need reference semantics – classes are stored on the heap, meaning changes to one object don't affect others (unlike structs, which we'll discuss next).
* When you need complex behavior – classes excel at encapsulating data and logic, making them ideal for representing real-world entities.
**The Lightweight Champion: The Struct**
Structs are value types, meaning they hold their data directly within the variable itself. Think of them as self-contained units, like coins in your pocket. Unlike classes, structs live on the stack, a faster-access memory region.
**Real-World Use Case:** A `Point` struct could hold `X` and `Y` coordinates, perfect for representing a point in 2D space.
**When to Choose a Struct:**
* When you need small, efficient data containers – structs are ideal for simple data like points, colors, or coordinates.
* When you need value semantics – changes to one struct variable don't affect others, as they're separate copies.
* When performance is critical – stack allocation for structs can be faster than heap allocation for classes.
**The New Kid on the Block: The Record**
C# 9 introduced records, a game-changer for value types. Records combine the best of both worlds: they offer value semantics like structs but come with built-in functionality for equality comparison, immutability (by default), and deconstruction. It's like having a pre-packaged value type with all the bells and whistles!
**Real-World Use Case:** A `Person` record could hold `Name`, `Age`, and a calculated `IsAdult` property. Records are perfect for immutable data that needs these built-in features.
**When to Choose a Record:**
* When you need value semantics with built-in functionality – records provide a clean and efficient way to handle data that doesn't need to change.
* When you want immutability by default – records are immutable unless you explicitly define setters.
* When you need deconstruction – records provide a convenient way to unpack their properties into variables.
**The Efficiency Enhancer: The Readonly Struct**
Readonly structs are a variation of structs specifically designed for scenarios where you know the data won't change after initialization. They offer the same benefits as structs (value semantics, stack allocation) but prevent accidental modifications.
**Real-World Use Case:** A `Rectangle` struct could be marked as readonly, ensuring its dimensions remain fixed after creation.
**When to Choose a Readonly Struct:**
* When you have data that shouldn't be modified after creation – readonly structs enforce immutability, preventing unintended side effects.
* When you want to optimize performance – readonly structs avoid the overhead of checking for modifications, potentially leading to slight performance gains.
**The Speedy Specialist: The Readonly Ref Struct**
Readonly ref structs, introduced in C# 7.2, are a powerful but niche concept. They offer the benefits of readonly structs (value semantics, immutability) with the ability to be passed to functions by reference. This can be particularly useful for performance-critical scenarios where avoiding unnecessary copies is paramount.
**Real-World Use Case:** A large `Matrix` struct could be marked as readonly ref, allowing functions to operate on the data directly without creating copies, potentially improving performance.
**When to Choose a Readonly Ref Struct:**
* When you need to pass large, immutable data by reference – readonly ref structs provide a way to avoid copying while maintaining immutability.
* When performance is absolutely critical – understanding the intricacies of readonly ref | waelhabbal |

Integrating a crypto payment gateway into your business is more than just a trend today. It’s a strategic decision. It enables smoother transactions, broader market access, and an advanced payment option for the future. But out of many options available, how do you select the best crypto payment gateway for your business? This article will help you understand what you should consider in a payment gateway.
**What you should Look for in a Crypto Payment Gateway?**
To choose the right payment gateway, merchants should be completely aware of their requirements. Since every merchant has different requirements for their payment systems, having clarity in the requirements can help them in selecting the best crypto payment gateway.
Some of the most common features merchants expect from a payment gateway include,
**Security**
Security should be every merchant’s top requirement from a cryptocurrency payment gateway. Cyber attacks have been a pressing concern for the crypto industry. In an article published by Reuters, cyber attackers stole around $1.7 billion last year. Therefore, choose a payment gateway that offers security features such as Two-Factor Authentication (2FA), encryption, and anti-fraud protection that protects customers' data.
**Supporting Multiple Cryptocurrencies**
A crypto payment processor must support multiple cryptocurrencies. Cryptocurrencies aren’t just about one or two coins. It is a set of different currencies. According to research done by Statista in 2023, there are over 9000 active cryptocurrencies. Therefore, having a gateway that supports various cryptocurrencies such as Bitcoin, Ethereum, and Dogecoin can allow you to cater to a wide customer base.
**Easy to Integrate**
To accept crypto payments smoothly, merchants should ensure that their selected payment gateway easily integrates into their e-commerce platforms. Look for a gateway that offers complete [crypto API](https://coinremitter.com/docs/api/v3/BTC) documentation that you can easily integrate without any technical challenges.
**Transaction Fees**
Transaction fees are a crucial consideration. High transaction fees can affect profits, especially in large or frequent transactions. A payment gateway that offers low transaction fees allows merchants to earn more.
**Authentication**
One of the biggest issues with crypto payment processors is that it requires merchants to go through the KYC verification procedure. While it is a necessary procedure, the process can be exhausting and time-consuming as the individual has to provide a large number of documents. Another reason is the fear of losing personal data. Data provided for KYC verification can result in a threat to the privacy of the individual. Thus, choosing payment gateways that allow users to sign up without KYC verification is a good option.
**Scalability**
Some payment gateways impose transaction limits. Now, if you experience a sudden demand in your business, these limits could cause financial loss and customer dissatisfaction. Therefore, look for a payment gateway that can handle increased demands and transaction volumes.
**Customer Support**
One of the biggest problems with crypto payment gateways is that they don’t provide sufficient support. Technical issues such as glitches and bugs are unavoidable, which is why merchants often require some form of technical assistance. An ideal payment gateway must offer instant support whenever required.
**Final Thought**
Accepting cryptocurrencies for payments can unlock several growth opportunities for your business. However, selecting the right payment gateway involves careful consideration of several factors. It’s best to select a [crypto payment gateway](https://coinremitter.com) that offers advanced security features such as Two-Factor Authentication (2FA), encryption, and code card. Also, it should easily integrate the gateway into platforms such as Magento, Woocommerce, and others.

Because it offers an organized representation of [HTML](https://www.nilebits.com/blog/2024/05/html-enhance-web-pages-overlooked-tags/) and XML content, the Document Object Model (DOM) is an essential component of web development. But was HTML developed before the DOM? This article explores the history of the DOM and HTML, looking at its inception, growth, and eventual fusion. We'll go over the technical details of both, including code samples to highlight important ideas. Comprehending the progression of these technologies illuminates the ways in which they have influenced the contemporary web and persist in influencing web development methodologies.
The Birth of HTML
HTML, or HyperText Markup Language, was invented by [Tim Berners-Lee](https://en.wikipedia.org/wiki/Tim_Berners-Lee) in 1991. It was designed to create a simple way to publish and navigate information on the web. The first version of HTML was relatively simple, consisting of basic tags for structuring documents.
```
<!DOCTYPE html>
<html>
<head>
<title>First HTML Document</title>
</head>
<body>
<h1>Hello, World!</h1>
<p>This is a paragraph.</p>
</body>
</html>
```
Early Days of HTML
HTML's initial versions lacked the sophisticated features we see today. It was primarily used to create static pages with text, links, and simple media elements. As the web grew, so did the need for more dynamic and interactive content.
The web was a new medium with little functionality in the early 1990s. The earliest websites were text-based and lacked the interactive features that we now consider standard. With more individuals utilizing the web, there was a growing desire for richer information and improved user experiences.
Tim Berners-Lee's Vision
The goal of Tim Berners-Lee's vision for the web was to establish an international information hub. By using hyperlinks to connect papers, he suggested a method that would make it easy for users to go from one piece of information to another. The World Wide Web and HTML as we know them today were made possible by this concept.
Berners-Lee's original proposal for HTML included a set of 18 elements designed to describe the structure of web documents. These elements allowed for the creation of headings, paragraphs, lists, and links, forming the basis of early web pages.
The Evolution of HTML
As the web evolved, so did HTML. New versions of HTML were developed to address the growing demands of web developers and users. HTML 2.0, released in 1995, was the first standardized version, providing a foundation for future enhancements. Subsequent versions introduced features like tables, forms, and multimedia support.
```
<!DOCTYPE html>
<html>
<head>
<title>HTML 2.0 Document</title>
</head>
<body>
<h1>HTML 2.0 Features</h1>
<p>This version introduced tables and forms.</p>
<table>
<tr>
<th>Column 1</th>
<th>Column 2</th>
</tr>
<tr>
<td>Data 1</td>
<td>Data 2</td>
</tr>
</table>
<form action="/submit">
<label for="name">Name:</label>
<input type="text" id="name" name="name">
<input type="submit" value="Submit">
</form>
</body>
</html>
```
The Need for More Interactivity
The web's promise as an interactive medium was starting to become apparent by the middle of the 1990s. The goal of development was to make user experiences more dynamic and captivating. The creation of scripting languages like JavaScript, which enabled client-side modification of web pages, was prompted by this demand for interaction.
The limitations of static HTML were becoming apparent, and the demand for dynamic content grew. JavaScript provided a way to manipulate HTML elements in real-time, paving the way for richer and more interactive web applications.
HTML's Role in Modern Web Development
Today, HTML remains the cornerstone of web development. Modern HTML, particularly HTML5, includes advanced features that support multimedia, graphics, and complex web applications. It provides a robust foundation for creating responsive and interactive websites.
```
<!DOCTYPE html>
<html>
<head>
<title>HTML5 Example</title>
</head>
<body>
<h1>HTML5 Features</h1>
<video width="320" height="240" controls>
<source src="movie.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;"></canvas>
<script>
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
context.fillStyle = '#FF0000';
context.fillRect(10, 10, 150, 75);
</script>
</body>
</html>
```
The evolution of HTML from its humble beginnings to its current form reflects the web's transformation into a powerful and versatile platform. HTML's continued development ensures that it remains relevant and capable of meeting the demands of modern web applications.
What is the DOM?
Web documents include a programming interface called the Document Object Model (DOM). Programs can alter the document's structure, design, and content by using it as a representation of the page. The document is shown by the DOM as a tree of objects, with each object denoting a different section of the content.
The Structure of the DOM
The DOM represents an HTML or XML document as a tree structure, where each node is an object representing a part of the document. This tree-like structure allows developers to navigate and manipulate the document's elements programmatically.
```
<!DOCTYPE html>
<html>
<head>
<title>DOM Example</title>
</head>
<body>
<h1 id="heading">Hello, World!</h1>
<p>This is a paragraph.</p>
<button id="changeText">Change Text</button>
<script>
// Accessing an element in the DOM
document.getElementById("changeText").addEventListener("click", function() {
document.getElementById("heading").innerHTML = "Text Changed!";
});
</script>
</body>
</html>
```
In the example above, the DOM represents the HTML document as a tree of objects. Each element (like the <h1> and <p> tags) is a node in the DOM tree. Using JavaScript, we can interact with these nodes to change the content and structure of the document dynamically.
How the DOM Works
The DOM is a language-neutral interface, meaning it can be used with different programming languages, although it is most commonly used with JavaScript in web development. It allows scripts to update the content, structure, and style of a document while it is being viewed.
Here are some key operations that can be performed using the DOM:
Accessing Elements: You can access elements by their ID, class, tag name, or other attributes.
```
var element = document.getElementById("myElement");
```
Modifying Elements: You can change the content, attributes, and style of elements.
```
element.innerHTML = "New Content";
element.style.color = "red";
```
Creating Elements: You can create new elements and add them to the document.
```
var newElement = document.createElement("div");
newElement.innerHTML = "Hello, DOM!";
document.body.appendChild(newElement);
```
Removing Elements: You can remove elements from the document.
```
var elementToRemove = document.getElementById("myElement");
elementToRemove.parentNode.removeChild(elementToRemove);
```
Evolution of the DOM
The DOM has evolved through several levels, each adding new capabilities and addressing limitations of previous versions.
DOM Level 1 (1998): The initial specification that provided basic methods for document manipulation.
DOM Level 2 (2000): Introduced support for XML namespaces, enhanced event handling, and improved CSS support.
DOM Level 3 (2004): Added support for XPath, better document traversal, and improved error handling.
Modern DOM Features
Modern web development relies heavily on the DOM for creating dynamic and interactive web applications. Here are some examples of modern DOM features:
Event Handling: Adding event listeners to respond to user actions.
```
document.getElementById("myButton").addEventListener("click", function() {
alert("Button clicked!");
});
```
Manipulating Attributes: Changing the attributes of elements.
```
var img = document.getElementById("myImage");
img.src = "new-image.jpg";
```
Working with Classes: Adding, removing, or toggling CSS classes.
```
var element = document.getElementById("myElement");
element.classList.add("newClass");
```
Traversing the DOM: Navigating through the DOM tree.
```
var parent = document.getElementById("childElement").parentNode;
var children = document.getElementById("parentElement").childNodes;
```
The Importance of the DOM
In order to build dynamic and interactive user experiences, modern web developers need to have access to the Document Object Model (DOM). It offers the basis for programmable online document manipulation, enabling real-time changes and interactions. The DOM keeps changing as web applications get more sophisticated, adding new features and functionalities to satisfy developers' needs.
Understanding the DOM and how to use it effectively is crucial for web developers. It allows them to create rich, interactive web applications that respond to user input and provide dynamic content, enhancing the overall user experience.
Standardization of the DOM
Diverse web browsers have incompatibilities because the Document Object Model (DOM) was not originally standardized. Due to these variations, early web developers had several difficulties while trying to construct web sites that functioned uniformly across all devices. Addressing these problems and guaranteeing a uniform method for manipulating online documents required the standardization of the DOM.
Early Implementations and Challenges
The two main scripting languages used to interact with HTML documents in the mid-1990s were Microsoft's JScript and Netscape's JavaScript. Compatibility problems resulted from the fact that every browser implemented a different version of the DOM. Cross-browser programming is difficult since different browsers have distinct ways of accessing and modifying document components, such as Internet Explorer and Netscape Navigator.
```
// Netscape Navigator
document.layers["myLayer"].document.open();
document.layers["myLayer"].document.write("Hello, Navigator!");
document.layers["myLayer"].document.close();
// Internet Explorer
document.all["myLayer"].innerHTML = "Hello, Explorer!";
```
The lack of a standardized model meant that developers had to write different code for different browsers, increasing development time and complexity. This fragmentation hindered the growth of the web as a platform for rich, interactive content.
The Role of the World Wide Web Consortium (W3C)
Acknowledging the necessity for uniformity, the World Wide Web Consortium (W3C) assumed the initiative in creating a common Document Object Model. To secure the web's continuous expansion, a global community known as the W3C creates open standards. DOM Level 1, the first standardized version of the DOM, was published by the W3C in 1998.
DOM Level 1 (1998)
DOM Level 1 provided a basic set of interfaces for manipulating document structures and content. It defined a standard way for scripts to access and update the content, structure, and style of HTML and XML documents. This standardization was a significant milestone, allowing developers to write code that worked consistently across different browsers.
```
// Standardized DOM Level 1 code
var element = document.getElementById("myElement");
element.innerHTML = "Hello, DOM!";
```
DOM Level 1 focused on providing a core set of features, including:
Document Navigation: Methods to traverse the document tree.
Element Manipulation: Methods to access and modify elements.
Event Handling: Basic support for handling events.
DOM Level 2 (2000)
DOM Level 2 expanded on the capabilities of DOM Level 1, introducing several new features:
XML Namespaces: Support for XML namespaces to handle documents with multiple XML vocabularies.
Enhanced Event Handling: Improved event model with support for event capturing and bubbling.
CSS Manipulation: Methods to access and manipulate CSS styles.
```
// Adding an event listener in DOM Level 2
document.getElementById("myButton").addEventListener("click", function() {
alert("Button clicked!");
});
```
DOM Level 3 (2004)
DOM Level 3 further enhanced the DOM by introducing new features and improving existing ones:
XPath Support: Methods to query documents using XPath expressions.
Document Traversal and Range: Interfaces for more sophisticated document navigation and manipulation.
Improved Error Handling: Enhanced mechanisms for handling errors and exceptions.
```
// Using XPath in DOM Level 3
var xpathResult = document.evaluate("//h1", document, null, XPathResult.ANY_TYPE, null);
var heading = xpathResult.iterateNext();
alert(heading.textContent);
```
Impact of Standardization
The standardization of the DOM by the W3C had a profound impact on web development:
Consistency: Developers could write code that worked across different browsers, reducing the need for browser-specific code.
Interoperability: Standardized methods and interfaces ensured that web pages behaved consistently, regardless of the user's browser.
Innovation: Standardization provided a stable foundation for further innovation in web technologies, enabling the development of advanced web applications.
Modern DOM Standards
The DOM continues to evolve, with modern standards building on the foundations laid by earlier versions. HTML5, for example, introduced new APIs and features that rely on the DOM, such as the Canvas API, Web Storage, and Web Workers.
```
// Using the HTML5 Canvas API with the DOM
var canvas = document.getElementById("myCanvas");
var context = canvas.getContext("2d");
context.fillStyle = "#FF0000";
context.fillRect(0, 0, 150, 75);
```
The standardization of the DOM was a critical step in the evolution of the web, providing a consistent and reliable way for developers to interact with web documents. The work of the W3C in developing and maintaining these standards has ensured that the web remains a powerful and versatile platform for creating dynamic and interactive content. As the DOM continues to evolve, it will continue to play a central role in the development of the web.
HTML and DOM: Intertwined Evolution
While HTML and the Document Object Model (DOM) were developed separately, their evolution became increasingly intertwined as the web matured. The need for dynamic, interactive content led to enhancements in HTML, and these improvements, in turn, relied on the DOM for interaction with web pages. This section explores how HTML and the DOM evolved together, highlighting key milestones and their impact on web development.
The Early Web: Static HTML and Limited Interactivity
Static web pages were the main use of HTML in the early days of the internet. There was very little to no interaction on these sites; they were just text, graphics, and links. Documents featuring components like headers, paragraphs, lists, and links might be organized using HTML.
```
<!DOCTYPE html>
<html>
<head>
<title>Early Web Page</title>
</head>
<body>
<h1>Welcome to the Early Web</h1>
<p>This is a simple, static web page.</p>
<a href="https://www.example.com">Visit Example</a>
</body>
</html>
```
However, as the web grew in popularity, there was a growing demand for more dynamic and interactive content. This demand led to the development of scripting languages like JavaScript, which enabled developers to manipulate HTML documents programmatically.
The Advent of JavaScript and Dynamic HTML
JavaScript, introduced by Netscape in 1995, revolutionized web development by allowing scripts to interact with the HTML document. This interaction was made possible through the DOM, which provided a structured representation of the document.
```
<!DOCTYPE html>
<html>
<head>
<title>Dynamic HTML Example</title>
</head>
<body>
<h1 id="heading">Hello, World!</h1>
<button onclick="changeText()">Change Text</button>
<script>
function changeText() {
document.getElementById("heading").innerHTML = "Text Changed!";
}
</script>
</body>
</html>
```
In this example, JavaScript uses the DOM to change the content of the <h1> element when the button is clicked. This capability marked the beginning of Dynamic HTML (DHTML), allowing for more interactive and engaging web pages.
The Evolution of HTML: Introducing New Elements and APIs
As web developers began to explore the possibilities of dynamic content, HTML continued to evolve. New versions of HTML introduced elements and attributes that enhanced the ability to create interactive web pages.
HTML 4.0 (1997): Introduced features like inline frames (<iframe>), enhanced form controls, and support for scripting languages.
HTML 5 (2014): Brought significant advancements, including new semantic elements, multimedia support, and APIs for offline storage, graphics, and real-time communication.
```
<!DOCTYPE html>
<html>
<head>
<title>HTML5 Example</title>
</head>
<body>
<header>
<h1>HTML5 Enhancements</h1>
</header>
<section>
<video width="320" height="240" controls>
<source src="movie.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
</section>
<canvas id="myCanvas" width="200" height="100" style="border:1px solid #000000;"></canvas>
<script>
var canvas = document.getElementById('myCanvas');
var context = canvas.getContext('2d');
context.fillStyle = '#FF0000';
context.fillRect(10, 10, 150, 75);
</script>
</body>
</html>
```
Modern Web Development: HTML5, CSS3, and JavaScript
Today, the core technologies of web development are HTML, CSS, and JavaScript. JavaScript allows for interactivity, whereas HTML supplies the structure and CSS manages the display. These technologies are held together and enable smooth operation together by the DOM.
HTML5 and New APIs
HTML5 introduced several new APIs that rely heavily on the DOM, enabling developers to create richer and more interactive web applications:
Canvas API: For drawing graphics and animations.
Web Storage API: For storing data locally within the user's browser.
Geolocation API: For retrieving the geographical location of the user.
```
// Using the Geolocation API with the DOM
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition(function(position) {
document.getElementById("location").innerHTML =
"Latitude: " + position.coords.latitude + "<br>" +
"Longitude: " + position.coords.longitude;
});
}
```
CSS3 and Advanced Styling
CSS3 introduced new features and capabilities for styling web pages, including animations, transitions, and transformations. These enhancements allow developers to create visually appealing and interactive user interfaces that work in tandem with the DOM.
```
/* CSS3 Transition Example */
#box {
width: 100px;
height: 100px;
background-color: blue;
transition: width 2s;
}
#box:hover {
width: 200px;
}
```
The Role of Frameworks and Libraries
Modern web development often involves the use of frameworks and libraries that abstract away many of the complexities of working with the DOM directly. Frameworks like React, Angular, and Vue.js provide powerful tools for building complex web applications, while still relying on the underlying DOM.
```
// React component example
class MyComponent extends React.Component {
constructor(props) {
super(props);
this.state = { text: "Hello, World!" };
}
changeText = () => {
this.setState({ text: "Text Changed!" });
}
render() {
return (
<div>
<h1>{this.state.text}</h1>
<button onClick={this.changeText}>Change Text</button>
</div>
);
}
}
ReactDOM.render(<MyComponent />, document.getElementById('root'));
```
Conclusion
The desire for increasingly dynamic and interactive web content has fueled the advancement of both HTML and the DOM. Together, HTML and the DOM have developed to satisfy the needs of both users and developers, from the static pages of the early web to the rich, dynamic apps of today. The evolution of the modern web will continue to revolve around the interaction between HTML and the DOM as web technologies progress.

- **Lazy Loading:** Implement lazy loading for images and other heavy resources to improve initial load times.
## 8. Load Balancing
- **Distribute Traffic:** Use load balancers to distribute incoming traffic across multiple servers, preventing any single server from becoming a bottleneck.
- **Horizontal Scaling:** Scale horizontally by adding more servers to handle increased load.
## 9. Session Management
- **Session Storage:** Store sessions in a shared memory store like Redis instead of file-based storage, which is faster and more reliable in distributed environments.
- **Session Optimization:** Limit session data size and clean up old sessions regularly.
## 10. Asynchronous Processing
- **Background Jobs:** Offload time-consuming tasks to background job queues using tools like RabbitMQ or Beanstalkd, allowing the main application to respond faster.
- **AJAX:** Use AJAX for non-critical tasks to improve the perceived responsiveness of the application.
## 11. Optimizing Frameworks and Libraries
- **Choose Wisely:** Select lightweight frameworks and libraries that are well-maintained and optimized for performance.
- **Trim Dependencies:** Remove unused libraries and keep dependencies to a minimum to reduce overhead.
## 12. Configuration Tweaks
- **PHP Configuration:** Adjust PHP settings like memory_limit, max_execution_time, and error_reporting to optimize performance.
- **Web Server Configuration:** Tune web server settings (e.g., Apache, Nginx) to handle PHP requests more efficiently.
## 13. Compression
- **Output Compression:** Enable Gzip compression on the web server to reduce the size of the data sent to the client.
- **Image Compression:** Compress images to reduce their size without sacrificing quality.
## 14. HTTP/2 and SSL/TLS
- **Enable HTTP/2:** Use HTTP/2 to benefit from multiplexing, header compression, and other performance improvements.
- **Optimize SSL/TLS:** Use modern SSL/TLS configurations to improve security and performance.
## 15. Content Optimization
- **Responsive Design:** Implement responsive design principles to ensure the application performs well on various devices.
- **Optimize Fonts:** Use web-safe fonts or host fonts locally to reduce load times.
## 16. Code Refactoring
- **Modular Code:** Write modular and reusable code to reduce duplication and improve maintainability.
- **Review and Refactor:** Regularly review and refactor code to remove inefficiencies and improve performance.
## 17. Advanced Techniques
- **PHP-FPM:** Use PHP-FPM (FastCGI Process Manager) for better performance and management of PHP processes.
- **APCu:** Utilize APCu (Alternative PHP Cache User) for user data caching.
## 18. Use Latest PHP Version
- **Upgrade PHP:** Always use the latest stable version of PHP, as it includes performance improvements and security patches.
- **Deprecation Handling:** Ensure that the codebase is compatible with newer PHP versions by handling deprecated features and functions.

Furthermore, Medusa supports all sorts of ecommerce app architectures. Be it headless, composable, semi-modular you name it, all scenarios work well with Medusa.
### Why Sveltekit?
Sveltekit is a framework based on the popular JavaScript library called Svelte. It has also gained a lot of popularity in the frontend community in the past few years. It is simple to understand, it is fast and performant and a useful alternative to the React ecosystem.
## Prerequisites
To follow along with the tutorial you need to have some knowledge of the following:
- Basic understanding of HTML, CSS, and JavaScript
- Basic understanding of Node.js and npm
- Basic understanding of the command line (Bash)
- Knowledge of Svelte and Sveltekit is a bonus but not a requirement.
- Knowledge of Medusa is a bonus but not a requirement.
In addition to knowing these tools, your computer system should have the following packages installed:
- [Node.js (v18 and above)](https://nodejs.org/en/download/package-manager)
- [yarn (optional)](https://yarnpkg.com/getting-started/install)
- [git](https://git-scm.com/downloads)
Before proceeding with the tutorial you can check out the following links for useful resources:
- [Video demo](https://www.youtube.com/watch?v=ghMgYLWTUlk).
- [Live link of the app](https://sveltekit-medusa-storefront.pages.dev/).
- [Git repo containing the project source code](https://github.com/Marktawa/sveltekit-medusa).
## Installation and setup of the Medusa server API
In this step you will install and set up the Medusa Server backend.
Open up your terminal and create a project folder to contain all the source code for the entire project. Name it `medusa-sveltekit`.
```bash
mkdir medusa-sveltekit
```
### Set up PostgreSQL on Neon
If you have PostgreSQL installed locally, you can skip this step.
Visit the [Neon - Sign Up](https://console.neon.tech/signup) page and create a new account.
[Create a new project](https://console.neon.tech/app/projects) in the Neon console. Give your project a name like `mystore` and your database a name like `storedb` then click **Create project**.
Take note of your connection string which will look something like: `postgresql://dominggobana:JyyuEdr809p@df-hidden-bonus-ertd7sio.us-east-3.aws.neon.tech/storedb?sslmode=require`. It is in the form `postgres://[user]:[password]@[host]/[dbname]`.You will provide connection string as a database URL to your Medusa server.
### Install Medusa CLI
In your terminal, inside the `my-store` folder run the following command to install the Medusa CLI. We will use it to install the Medusa server.
```bash
npm install @medusajs/medusa-cli -g
```
### Create a new Medusa project
```bash
medusa new my-medusa-store
```
You will be asked to specify your PostgreSQL database credentials. Choose "Skip database setup".
A new directory named `my-medusa-store` will be created to store the server files.
### Configure Database - Neon Users
If you have PostgreSQL installed locally, you can skip this step.
Add the connection string as the `DATABASE_URL` to your environment variables. Inside `my-medusa-store` create a `.env` file and add the following:
```
DATABASE_URL=postgresql://dominggobana:JyyuEdr809p@df-hidden-bonus-ertd7sio.us-east-3.aws.neon.tech/mystoredb?sslmode=require
```
### Configure Database - Local PostgreSQL DB
If you have PostgreSQL configured on Neon, you can skip this step.
Access the PostgreSQL console to create a new user and database for the Medusa server.
```bash
sudo -u postgres psql
```
To create a new user named `medusa_admin` run this command:
```sql
CREATE USER medusa_admin WITH PASSWORD 'medusa_admin_password';
```
Now, create a new database named `medusa_db` and make `medusa_admin` the owner.
```sql
CREATE DATABASE medusa_db OWNER medusa_admin;
```
Last, grant all privileges to `medusa_admin` and exit the PostgreSQL console.
```sql
GRANT ALL PRIVILEGES ON DATABASE medusa_db TO medusa_admin;
```
```sql
exit
```
Add the connection string as the `DATABASE_URL` to your environment variables. Inside `my-medusa-store` create a `.env` file and add the following:
```
DATABASE_URL=postgres://medusa_admin:medusa_admin_password@localhost:5432/medusa_db
```
### Seed Database
Run migrations and seed data to the database by running the following command:
```bash
cd my-medusa-store
medusa seed --seed-file="./data/seed.json"
```
### Start your Medusa backend
```bash
medusa develop
```
The Medusa server will start running on port `9000`.
Test your server:
```bash
curl localhost:9000/store/products
```
If it is working, you should see a list of products.
## Install and Serve Medusa Admin with the Backend
This section explains how to install the admin to be served with the Medusa Backend.
### Install the package
Inside `my-medusa-store` stop your Medusa server, `CTRL + C` and run the following command to install the Medusa Admin Dashboard.
```bash
npm install @medusajs/admin
```
Test your install by re-running your server.
```bash
medusa develop
```
Open up your browser and visit `localhost:7001` to see the Medusa Admin Dashboard. Use the Email `admin@medusa-test.com` and password `supersecret` to log in.
## Set Up Sveltekit
### Create a Sveltekit project
Open up a new terminal session inside the `medusa-sveltekit` directory. Run the following commands:
```bash
npm create svelte@latest storefront
cd storefront
npm install
```
Answer the prompts as follows:
- `Which Svelte app template?`, Answer: `Skeleton project (Barebones scaffolding for your new SvelteKit app)`
- `Add type checking with TypeScript?`, Answer: `No`
- `Select additional options (use arrow keys/space bar)` Leave it blank.
This will scaffold a new project in the `storefront` directory.
## Link Storefront To Server
### Configure SvelteKit Storefront URL
To link the Medusa server with the Sveltekit storefront, first, open up your Medusa project, `my-medusa-store` in your code editor, then open the `.env` file where all your environment variables are set up.
Add the variable `STORE_CORS` with the value of the URL where your storefront will be running. SvelteKit by default runs on port `5173`.
```
STORE_CORS=http://localhost:5173
```
After this, your Medusa server will be ready to receive a request from your storefront and send back responses if everything works as expected.
### List Products on Sveltekit Storefront
Open up the `storefront` directory in your code editor, and create a new file named `src/routes/+page.js`. This file will export a load function and the return value which is available to the page via the `data` prop:
```js
/** @type {import(./$types').PageLoad} */
export async function load({ fetch }) {
const res = await fetch(`http://localhost:9000/store/products`);
const payload = await res.json();
return { payload };
}
```
Replace the existing code in `src/routes/+page.svelte` with the following:
```svelte
<script>
/** @type {import('./$types').PageData} */
export let data;
</script>
<h1>Welcome to the Medusa SvelteKit Store</h1>
<h2>Products</h2>
<ul>
{#each data.payload.products as product}
<li>{product.title} - ${product.variants[0].prices[0].amount}</li>
{/each}
</ul>
```
Open up the `storefront` directory in your terminal and start the SvelteKit development server.
```bash
npm run dev
```
Visit [`localhost:5173`](http://localhost:5173) in your browser to see the list of products from your Medusa backend.
## Add Cart
Update `src/routes/+page.svelte` with the following code, to create a cart on page load:
```svelte
<script>
/** @type {import('./$types').PageData} */
export let data;
import { onMount } from 'svelte';
onMount(async () => {
fetch(`http://localhost:9000/store/carts`, {
method: "POST",
credentials: "include",
})
.then((response) => response.json())
.then(({ cart }) => {
localStorage.setItem("cart_id", cart.id)
console.log("The cart ID is " + localStorage.getItem("cart_id"));
});
});
</script>
<h1>Welcome to the Medusa SvelteKit Store</h1>
<h2>Products</h2>
<ul>
{#each data.payload.products as product}
<li>{product.title} - ${product.variants[0].prices[0].amount}</li>
{/each}
</ul>
```
Revisit `localhost:5173` in your browser and open the `Console` section of your Dev Tools. You should see a message with a cart ID to confirm creation of the cart.
Update each product in `src/routes/+page.svelte` with a button to add a product to the cart.
```svelte
<script>
/** @type {import('./$types').PageData} */
export let data;
import { onMount } from 'svelte';
onMount(async () => {
fetch(`http://localhost:9000/store/carts`, {
method: "POST",
credentials: "include",
})
.then((response) => response.json())
.then(({ cart }) => {
localStorage.setItem("cart_id", cart.id)
console.log("The cart ID is " + localStorage.getItem("cart_id"));
});
});
function addProductToCart(variant_id) {
const id = localStorage.getItem("cart_id");
fetch(`http://localhost:9000/store/carts/${id}/line-items`, {
method: "POST",
dentials: "include",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
variant_id,
quantity: 1,
}),
})
.then((response) => response.json());
//.then(({ cart }) => setCart(cart));
}
</script>
<h1>Welcome to the Medusa SvelteKit Store</h1>
<h2>Products</h2>
<ul>
{#each data.payload.products as product}
<li>
{product.title} - ${product.variants[0].prices[0].amount}
<button on:click={() => {
addProductToCart(product.variants[0].id);
alert('Added to Cart');
}}
>
Add To Cart
</button>
</li>
{/each}
</ul>
```
Confirm whether the products are being added to the cart by performing a curl request as follows:
```bash
curl localhost:9000/store/carts/cart_01HRBTB0X79NAGJYY8T6D5BGK6
```
Replace with the specific `cart id` as listed in your browser console. If all is working your cart should be populated with some products.
The next step is to display the cart by creating a cart page.
Create a new folder inside `src/routes` named `cart`. Add a `+page.svelte` file to the `cart` folder.
Add the following code to `src/routes/cart/+page.svelte`:
```svelte
<script>
import { onMount } from "svelte";
let data;
let total;
let items = [];
onMount(async () => {
const id = localStorage.getItem("cart_id");
const res = await fetch(`http://localhost:9000/store/carts/${id}`, {
credentials: "include",
});
data = await res.json();
items = data.cart.items;
total = data.cart.total;
});
</script>
<h1>Welcome to the Medusa SvelteKit Store</h1>
<h2>Cart</h2>
<ul>
{#each items as item}
<li>
TITLE: {item.title} PRICE: {item.unit_price} QUANTITY: {item.quantity}
</li>
{/each}
</ul>
<p>The total price for your cart is {total}</p>
```
Test your cart page by adding some products to your cart then visiting `localhost:5173/cart` in your browser. You should see a list of products with the quantity and price info as well as the cart total.
Next, associate your cart with an email address for the user. This is necessary to complete the cart.
```svelte
<script>
import { onMount } from "svelte";
let data;
let email;
let total;
let items = [];
onMount(async () => {
const id = localStorage.getItem("cart_id");
const res = await fetch(`http://localhost:9000/store/carts/${id}`, {
credentials: "include",
});
data = await res.json();
items = data.cart.items;
total = data.cart.total;
});
function addCustomer() {
const id = localStorage.getItem("cart_id");
fetch(`http://localhost:9000/store/carts/${id}`, {
method: "POST",
credentials: "include",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
email: email,
}),
})
.then((response) => response.json())
.then(({ cart }) => {
console.log("Customer ID is " + cart.customer_id)
console.log("Customer email is " + cart.email)
});
}
</script>
<h1>Welcome to the Medusa SvelteKit Store</h1>
<h2>Cart</h2>
<ul>
{#each items as item}
<li>
TITLE: {item.title} PRICE: {item.unit_price} QUANTITY: {item.quantity}
</li>
{/each}
</ul>
<p>The total price for your cart is {total}</p>
<p>Enter your email to Proceed to Checkout</p>
<input id="email" type="email" bind:value={email}>
<button type="submit" on:click={() => {
addCustomer();
alert('Added your Email');
}}
>
Submit
</button>
```
## Add Checkout Functionality
Create a page called, `src/routes/checkout/+page.svelte` to load the checkout page.
Add the following code to initialize the payment session:
```svelte
<script>
import { onMount } from "svelte";
onMount(async () => {
const id = localStorage.getItem("cart_id");
fetch(`http://localhost:9000/store/carts/${id}/payment-sessions`, {
method: "POST",
credentials: "include",
})
.then((response) => response.json())
.then(({ cart }) => {
console.log(cart.payment_sessions)
})
});
</script>
<h1>Welcome to the Medusa SvelteKit Store</h1>
<h2>Checkout</h2>
```
Visit `localhost:5173/checkout` in your browser and open up the Console in your Devtools.
## Add Cart Completion
Next add Cart completion to the checkout process, by adding the following code:
```js
medusa.carts.createPaymentSessions(cartId)
.then(({ cart }) => {
console.log(cart.payment_sessions)
})
```
```svelte
<script>
import { onMount } from "svelte";
onMount(async () => {
const id = localStorage.getItem("cart_id");
fetch(`http://localhost:9000/store/carts/${id}/payment-sessions`, {
method: "POST",
credentials: "include",
})
.then((response) => response.json())
.then(({ cart }) => {
console.log(cart.payment_sessions)
})
});
function completeCart() {
const id = localStorage.getItem("cart_id");
fetch(`http://localhost:9000/store/carts/${id}/complete`, {
method: "POST",
dentials: "include",
headers: {
"Content-Type": "application/json",
},
})
.then((response) => response.json())
.then(({ type, data }) => {
console.log(type, data)
})
}
</script>
<h1>Welcome to the Medusa SvelteKit Store</h1>
<h2>Checkout</h2>
<button on:click={() => {
completeCart();
alert('Cart Complete');
}}
>
Complete Cart
</button>
```
Click on the `Complete Cart` button to test if the order was completed using the manual Medusa payment provider. You should see the following:
## Add Payment Provider
Stripe is a battle-tested and unified platform for transaction handling. Stripe supplies you with the technical components needed to handle transactions safely and all the analytical features necessary to gain insight into your sales. These features are also available in a safe test environment which allows for a concern-free development process.
Using the `medusa-payment-stripe plugin`, you will set up your Medusa project with Stripe as a payment processor.
[Create a Stripe account](https://dashboard.stripe.com/register) and retrieve the [Stripe Secret API Key](https://dashboard.stripe.com/test/apikeys) from your account to connect Medusa to your Stripe account.
Add the key to your environment variables in `.env` in `my-medusa-store`.
```
STRIPE_API_KEY=sk_...
```
### Install Stripe Plugin
Open up your terminal, in the root of your Medusa backend. Stop your Medusa server and run the following command to install the Stripe plugin:
```bash
npm install medusa-payment-stripe
```
### Configure the Stripe Plugin
Next, you need to add configurations for your Stripe plugin.
In `medusa-config.js`, add the following at the end of the plugins array:
```js
const plugins = [
// ...
{
resolve: `medusa-payment-stripe`,
options: {
api_key: process.env.STRIPE_API_KEY,
},
},
]
```
### Add Stripe to Region in Medusa Admin
Make sure your Medusa backend server is running, then log in to your Medusa Admin Dashboard.
Go to **Settings** then select **Regions**.
Select a region to edit.
Click on the three dots icon at the top right of the first section on the right. Click on Edit Region Details from the dropdown.
Under the providers section, add all `Stripe` options to the region. Unselect the payment providers you want to remove from the region. Click the "Save and close" button.
### Add Stripe Key to Sveltekit Storefront
Add your Stripe Publishable API Key to your Sveltekit storefront environment variables. Open up `.env` in your Sveltekit Storefront and add the following:
```
PUBLIC_STRIPE_KEY=<YOUR_PUBLISHABLE_KEY>
```
### Install Dependencies
Install the necessary dependencies to show the UI and handle the payment confirmation:
```bash
npm install --save stripe @stripe/stripe-js svelte-stripe
```
You’ll also use Medusa’s JS Client to easily call Medusa’s REST APIs:
```bash
npm install @medusajs/medusa-js
```
### Add Stripe
Update the checkout page for the Stripe payment option. Open up `src/routes/checkout/+page.svelte` in your code editor.
```svelte
<script>
import { onMount } from 'svelte';
import { loadStripe } from '@stripe/stripe-js';
import { PUBLIC_STRIPE_KEY } from '$env/static/public';
import { Elements, PaymentElement, LinkAuthenticationElement, Address } from 'svelte-stripe';
import Medusa from '@medusajs/medusa-js';
let stripe = null;
let clientSecret = null;
let error = null;
let elements;
let processing = false;
let cartId = null;
onMount(async () => {
stripe = await loadStripe(PUBLIC_STRIPE_KEY);
const client = new Medusa();
cartId = localStorage.getItem("cart_id");
try {
const { cart } = await client.carts.createPaymentSessions(cartId);
const isStripeAvailable = cart.payment_sessions?.some(
(session) => session.provider_id === 'stripe'
);
if (!isStripeAvailable) return;
const { cart: updatedCart } = await client.carts.setPaymentSession(cartId, {
provider_id: 'stripe',
});
setClientSecret(updatedCart.payment_session.data.client_secret);
} catch (error) {
console.error('Error creating payment session:', error);
}
});
function setClientSecret(secret) {
clientSecret = secret;
}
async function submit() {
// avoid processing duplicates
if (processing) return
processing = true
// confirm payment with stripe
const result = await stripe.confirmPayment({
elements,
redirect: 'if_required'
})
// log results, for debugging
console.log({ result })
if (result.error) {
// payment failed, notify user
error = result.error
processing = false
} else {
// payment succeeded, redirect to "thank you" page
const client = new Medusa();
const response = await client.carts.complete(cartId);
console.log(response);
}
}
</script>

```
### Add Success Page
Create a new directory named `thanks` in the `src/routes` path. In it add a `+page.svelte` file with the following code:
```svelte
<h1>Success!</h1>
<p>Payment was successfully processed.</p>
```
Update `src/routes/checkout/+page.svelte` so that once the payment is done the store will redirect to the Success page:
```svelte
<script>
import { goto } from '$app/navigation';
import { onMount } from 'svelte';
import { loadStripe } from '@stripe/stripe-js';
import { PUBLIC_STRIPE_KEY } from '$env/static/public';
import { Elements, PaymentElement } from 'svelte-stripe';
import Medusa from '@medusajs/medusa-js';
let stripe = null;
let clientSecret = null;
let error = null;
let elements;
let processing = false;
let cartId = null;
onMount(async () => {
stripe = await loadStripe(PUBLIC_STRIPE_KEY);
const client = new Medusa();
cartId = localStorage.getItem("cart_id");
try {
const { cart } = await client.carts.createPaymentSessions(cartId);
const isStripeAvailable = cart.payment_sessions?.some(
(session) => session.provider_id === 'stripe'
);
if (!isStripeAvailable) return;
const { cart: updatedCart } = await client.carts.setPaymentSession(cartId, {
provider_id: 'stripe',
});
setClientSecret(updatedCart.payment_session.data.client_secret);
} catch (error) {
console.error('Error creating payment session:', error);
}
});
function setClientSecret(secret) {
clientSecret = secret;
}
async function submit() {
// avoid processing duplicates
if (processing) return
processing = true
// confirm payment with stripe
const result = await stripe.confirmPayment({
elements,
redirect: 'if_required'
})
// log results, for debugging
console.log({ result })
if (result.error) {
// payment failed, notify user
error = result.error
processing = false
} else {
// payment succeeded, redirect to "thank you" page
const client = new Medusa();
const response = await client.carts.complete(cartId);
console.log(response);
goto('../thanks')
}
}
</script>

</style>
```
### Test Payment
Test if the Stripe integration has worked well by making test a payment. If everything is working your checkout page should appear like this.
A successful payment should lead users to the following page:
### Capture Payment
Visit the Orders section in your Medusa Admin and click on the order you placed earlier in your storefront to capture it.
You can check to see if the payment was successful in your Stripe Dashboard [Payment Section](https://dashboard.stripe.com/test/payments), after capturing it in your Medusa Dashboard.
## UI Design
In the next section, we will design the UI for our storefront.
### Add Layout
Add a layout file for the common UI elements like the header and footer. Open up your `storefront` folder and add a `src/routes/+layout.svelte` file inside.
Add the following code to `src/routes/+layout.svelte`:
```svelte
<div class="pagewrapper">
<header id="header">
<a href="/">HOME</a>
<h1><a href="/">MY STORE</a></h1>
<a href="/cart">CART</a>
</header>
<main id="main">
<slot />
</main>
<footer id="footer">
<p>Copyright 2024.</p>
<p>Made Using Sveltekit and Medusa</p>
</footer>
</div>
<style>
* {
margin: 0;
padding: 0;
}
.pagewrapper {
max-width: 1440px;
font-family: Inter, -apple-system, BlinkMacSystemFont, Segoe UI, Roboto, Helvetica Neue, Ubuntu, sans-serif;
margin: 0 auto;
}
header {
padding: 0.6rem 1.2rem;
display: flex;
justify-content: space-between;
text-align: center;
align-items: center;
border-bottom: 1px solid #000;
}
a {
list-style: none;
text-decoration: none;
color: inherit;
}
footer {
font-size: 0.6rem;
display: flex;
justify-content: space-between;
margin-top: 2rem;
padding: 0.75rem 1.5rem;
border-top: 1px solid #000;
}
</style>
```
### Home Page
We will start off with the home page design. The home page will be based on the following design.
Update the code for the home page, `src/routes/+page.svelte` as follows:
```svelte
<script>
/** @type {import('./$types').PageData} */
export let data;
import { onMount } from "svelte";
onMount(async () => {
fetch(`http://localhost:9000/store/carts`, {
method: "POST",
credentials: "include",
})
.then((response) => response.json())
.then(({ cart }) => {
localStorage.setItem("cart_id", cart.id);
console.log("The cart ID is " + localStorage.getItem("cart_id"));
});
});
function addProductToCart(variant_id) {
const id = localStorage.getItem("cart_id");
fetch(`http://localhost:9000/store/carts/${id}/line-items`, {
method: "POST",
dentials: "include",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
variant_id,
quantity: 1,
}),
}).then((response) => response.json());
//.then(({ cart }) => setCart(cart));
}
</script>

Make sure your Medusa development server and Sveltekit development server are running and then visit the home page, [localhost:5173](http://localhost:5173) to view the changes.
### Cart Page
Update the code for the cart page, `src/routes/cart/+page.svelte` as follows:
```svelte
<script>
import { onMount } from "svelte";
let data;
let email;
let total;
let items = [];
onMount(async () => {
const id = localStorage.getItem("cart_id");
const res = await fetch(`http://localhost:9000/store/carts/${id}`, {
credentials: "include",
});
data = await res.json();
items = data.cart.items;
total = data.cart.total;
});
function addCustomer() {
const id = localStorage.getItem("cart_id");
fetch(`http://localhost:9000/store/carts/${id}`, {

Make sure your Medusa development server and Sveltekit development server are running and then add some products to your cart. Visit the cart page, [localhost:5173/cart](http://localhost:5173/cart) to view the changes.
### Checkout Page
Update the code for the checkout page, `src/routes/checkout/+page.svelte` as follows:
```svelte
<script>
import { goto } from '$app/navigation';
import { onMount } from 'svelte';
import { loadStripe } from '@stripe/stripe-js';
import { PUBLIC_STRIPE_KEY } from '$env/static/public';
import { Elements, PaymentElement } from 'svelte-stripe';
import Medusa from '@medusajs/medusa-js';
let stripe = null;
let clientSecret = null;
let error = null;
let elements;
let processing = false;
let cartId = null;
onMount(async () => {
stripe = await loadStripe(PUBLIC_STRIPE_KEY);
const client = new Medusa();
cartId = localStorage.getItem("cart_id");
try {
const { cart } = await client.carts.createPaymentSessions(cartId);
const isStripeAvailable = cart.payment_sessions?.some(
(session) => session.provider_id === 'stripe'
);
if (!isStripeAvailable) return;
const { cart: updatedCart } = await client.carts.setPaymentSession(cartId, {
provider_id: 'stripe',
});
setClientSecret(updatedCart.payment_session.data.client_secret);
} catch (error) {
console.error('Error creating payment session:', error);
}
});
function setClientSecret(secret) {
clientSecret = secret;
}
async function submit() {
// avoid processing duplicates
if (processing) return
processing = true
// confirm payment with stripe
const result = await stripe.confirmPayment({
elements,
redirect: 'if_required'
})
// log results, for debugging
console.log({ result })
if (result.error) {
// payment failed, notify user

```
Complete your cart by clicking on `Proceed to Checkout` button and visit the checkout page, [localhost:5173/checkout](http://localhost:5173/checkout) to view the changes.
### Success Page
Make a payment using the Stripe Test card `4242 4242 4242 4242` and this will lead to the success page.
```svelte
<h2>Success!</h2>
<section id="success">
<p>Payment was successfully processed.</p>
</section>
<style>
h2 {
text-align: center;
font-size: 3rem;
padding: 4rem 0 2rem 0;
}
#success {

margin-right: auto;
margin-bottom: 8rem;
max-width: 24rem;
padding: 0 0.5rem;
}
p {
text-align: center;
}
</style>
```
## Update Storefront Environment Variables
In this step you will replace the hardcoded URL to the Medusa backend with an environment variable, `MEDUSA_BACKEND_URL` in all your storefront files. This will be useful when deploying the storefront in the next steps.
Open up `.env` in your Sveltekit Storefront and and add the following:
```
PUBLIC_MEDUSA_BACKEND_URL=http://localhost:9000
```
Open up all the files in your storefront project folder where the URL to the Medusa backend is hardcoded. Add the following import statement at the top of each file:
```svelte
<script>
import { PUBLIC_MEDUSA_BACKEND_URL } from '$env/static/public';
//...
```
Replace every occurence of `http://localhost:9000` with `PUBLIC_MEDUSA_BACKEND_URL`. The files are `src/routes/+page.js`, `src/routes/+page.svelte`, `src/routes/cart/+page.svelte`, and `src/routes/checkout/+page.svelte`.
The following is the updated `src/routes/+page.js`:
```js
import { MEDUSA_BACKEND_URL } from '$env/static/public'
/** @type {import(./$types').PageLoad} */
export async function load({ fetch }) {
const res = await fetch(`${PUBLIC_MEDUSA_BACKEND_URL}/store/products`);
const payload = await res.json();
return { payload };
}
```
The updated `src/routes/+page.svelte` will be as follows:
```svelte
<script>
/** @type {import('./$types').PageData} */
export let data;
import { onMount } from "svelte";
import { PUBLIC_MEDUSA_BACKEND_URL } from '$env/static/public';
onMount(async () => {
fetch(`${PUBLIC_MEDUSA_BACKEND_URL}/store/carts`, {
method: "POST",
credentials: "include",
})
.then((response) => response.json())
.then(({ cart }) => {
localStorage.setItem("cart_id", cart.id);
console.log("The cart ID is " + localStorage.getItem("cart_id"));
});
});
function addProductToCart(variant_id) {
const id = localStorage.getItem("cart_id");
fetch(`${PUBLIC_MEDUSA_BACKEND_URL}/store/carts/${id}/line-items`, {
method: "POST",
dentials: "include",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
variant_id,
quantity: 1,
}),
}).then((response) => response.json());
//.then(({ cart }) => setCart(cart));
}
</script>
<!--...-->
```
The updated `src/routes/cart/+page.svelte` will be as follows:
```svelte
<script>
import { onMount } from "svelte";
import { PUBLIC_MEDUSA_BACKEND_URL } from '$env/static/public';
let data;
let email;
let total;
let items = [];
onMount(async () => {
const id = localStorage.getItem("cart_id");
const res = await fetch(`${PUBLIC_MEDUSA_BACKEND_URL}/store/carts/${id}`, {
credentials: "include",
});
data = await res.json();
items = data.cart.items;
total = data.cart.total;
});
function addCustomer() {
const id = localStorage.getItem("cart_id");
fetch(`${PUBLIC_MEDUSA_BACKEND_URL}/store/carts/${id}`, {
method: "POST",
credentials: "include",
headers: {
"Content-Type": "application/json",
},
body: JSON.stringify({
email: email,
}),
})
.then((response) => response.json())
.then(({ cart }) => {
console.log("Customer ID is " + cart.customer_id);
console.log("Customer email is " + cart.email);
});
}
</script>
<!--...-->
```
The following is the updated `src/routes/checkout/+page.svelte`:
```svelte
<script>
import { goto } from '$app/navigation';

import Medusa from '@medusajs/medusa-js';
let stripe = null;
let clientSecret = null;
let error = null;
let elements;
let processing = false;
let cartId = null;
onMount(async () => {
stripe = await loadStripe(PUBLIC_STRIPE_KEY);
const client = new Medusa({ baseUrl: PUBLIC_MEDUSA_BACKEND_URL, maxRetries: 3 });

try {
const { cart } = await client.carts.createPaymentSessions(cartId);
const isStripeAvailable = cart.payment_sessions?.some(
(session) => session.provider_id === 'stripe'
);
if (!isStripeAvailable) return;
const { cart: updatedCart } = await client.carts.setPaymentSession(cartId, {
provider_id: 'stripe',

const response = await client.carts.complete(cartId);
console.log(response);
goto('../thanks')
}
}
</script>

```
## Deployment
In this section, we will look into the deployment of the ecommerce app. We will start off with the deployment of the Medusa Server and Admin then look into the deployment of the Sveltekit storefront.
## Deploy Medusa Server
We will deploy the Medusa Backend Server on [Railway](https://railway.app). Railway provides a free trial (no credit card required) that allows you to deploy your Medusa backend along with PostgreSQL and Redis databases. This is useful mainly for development and demo purposes. Sign up for a Railway account and proceed with the following steps.
### Create GitHub Repo
Navigate to the Medusa server directory `my-medusa-store` in your local machine. Duplicate the folder and create a new GitHub repo based on this directory to handle all the config related to the server only.
### Add Railway Configuration File
To avoid errors during the installation process, it's recommended to use `yarn` for installing the dependencies. Alternatively, pass the `--legacy-peer-deps` option to the npm command.
Add in the root of your Medusa server project the file, `railway.toml`, with the content based on the package manager of your choice:
Using `yarn`:
```toml
[build]
builder = "NIXPACKS"
[build.nixpacksPlan.phases.setup]
nixPkgs = ["nodejs", "yarn"]
[build.nixpacksPlan.phases.install]
cmds=["yarn install"]
```
Using `npm`:
```toml
[build]
builder = "NIXPACKS"
[build.nixpacksPlan.phases.setup]
nixPkgs = ["nodejs", "npm"]
[build.nixpacksPlan.phases.install]
cmds=["npm install --legacy-peer-deps"]
```
### Configure Server for Production
Open the `medusa-config.js` file in your new server repo.
Update the following parts to enable caching using Redis.
Uncomment the inner part of the following section:
```js
const modules = {
/*eventBus:
resolve: "@medusajs/event-bus-redis",
```
Uncomment the following section as well:
```js
// Uncomment the following lines to enable REDIS
// redis_url: REDIS_URL
```
It then becomes:
```js
//...
const modules = {
eventBus: {
resolve: "@medusajs/event-bus-redis",
options: {
redisUrl: REDIS_URL
}
},
cacheService: {
resolve: "@medusajs/cache-redis",
options: {
redisUrl: REDIS_URL
}
},
};
/** @type {import('@medusajs/medusa').ConfigModule["projectConfig"]} */
const projectConfig = {
jwtSecret: process.env.JWT_SECRET,
cookieSecret: process.env.COOKIE_SECRET,
store_cors: STORE_CORS,
database_url: DATABASE_URL,
admin_cors: ADMIN_CORS,
redis_url: REDIS_URL
};
//...
```
Since we are deploying the admin separately, disable the admin plugin's [serve option](https://docs.medusajs.com/admin/configuration#plugin-options).
```js
const plugins = [
// ...
{
resolve: "@medusajs/admin",
/** @type {import('@medusajs/admin').PluginOptions} */
options: {
// only enable `serve` in development
// you may need to add the NODE_ENV variable
// manually
serve: process.env.NODE_ENV === "development",
// other options...
autoRebuild: true,
develop: {
open: process.env.OPEN_BROWSER !== "false",
},
},
},
]
```
This ensures that the admin isn't built or served in production. You can also change `@medusajs/admin` dependency to be a devdependency in `package.json`.
Also, change the `build` command to remove the command that builds the admin inside the `package.json` file:
```js
"scripts": {
// ...
"build": "cross-env npm run clean && npm run build:server",
}
//...
"devDependencies": {
//...
"@medusajs/admin": "^7.1.11",
}
```
Commit your changes, and push them to your remote GitHub repository. Once your repository is ready on GitHub, log in to your Railway dashboard.
### Create Project + PostgreSQL Database
If you are using Neon for your PostgreSQL database please skip this step.
On the Railway Dashboard, click on the **New Project** button and choose from the list the **Deploy PostgreSQL** option.
A new database will be created and, after a few seconds, you'll be redirected to the project page where you'll see the newly-created database.
### Migrate local PostgreSQL database to Railway
If you are using Neon for your PostgreSQL database please skip this step.
Open your terminal and run the following command to dump the local database to file:
```bash
pg_dump medusa_db > medusa_db.sql
```
Copy the `DATABASE_URL` from your Railway Dashboard. Then export the database dump, `medusa_db.sql` into the new database on the remote Railway server:
```bash
psql DATABASE_URL < medusa_db.sql
```
Replace `DATABASE_URL` with the value from your Railway Dashboard.
### Create the Redis Database
In the same project view, click on the **Create** button, choose the **Database** option and select **Add Redis**.
A new Redis database will be added to the project view in a few seconds. Click on it to open the database sidebar.
### Deploy Medusa in Server Mode
In this section, you'll create a Medusa backend instance running in `server` runtime mode.
In the same project view, click on the **Create** button and choose the **GitHub Repo** option. If you still haven't given GitHub permissions to Railway, choose the **Configure GitHub App** option.
Choose the repository from the GitHub Repo dropdown.
### Configure Backend Environment Variables
To configure the environment variables of your Medusa backend, click on the GitHub repo card and choose the **Variables** tab and add the following environment variables:
```
PORT=9000
JWT_SECRET=something
COOKIE_SECRET=something
DATABASE_URL=${{Postgres.DATABASE_URL}}
REDIS_URL=${{Redis.REDIS_URL}}
STORE_CORS=http://localhost:5173
ADMIN_CORS=http://localhost:7001
STRIPE_API_KEY=sk_test_XXXXXXXXXXXX
```
Notice that the values of `DATABASE_URL` and `REDIS_URL` reference the values from the PostgreSQL and Redis databases you created earlier.
For Neon users, insert the URL to your Postgres database hosted on Neon as the value to `DATABASE_URL`.
>**NOTE**
>
>The values for `STORE_CORS` and `ADMIN_CORS` will be updated after deploying the admin and storefront.
>Use strong, randomly generated secrets for `JWT_SECRET` and `COOKIE_SECRET`.
### Change Backend's Start Command
The start command is the command used to run the backend. You’ll change it to run any available migrations, then run the Medusa backend. This way if you create your own migrations or update the Medusa backend, it's guaranteed that these migrations run first before the backend starts.
Click on the GitHub repository's card, select the **Settings** tab and scroll down to the **Deploy** section. Click on the **Start** command button and paste the following command:
```bash
medusa migrations run && medusa start
```
### Add Domain Name
Click on the Medusa server runtime card and select the **Settings** tab and scroll down to the **Networking** section. Either select **Custom Domain** or select **Generate Domain** to generate a random button.
### Deploy Changes
At the top left of your project's dashboard page, there's a **Deploy** button that deploys all the changes you've made so far.
Click on the button to trigger the deployment. The deployment will take a few minutes before it's ready.
### Test the Backend
Once the deployment is finished, you can access the Medusa backend on the custom domain/domain you've generated.
For example, you can open the URL `<YOUR_APP_URL>/store/products` which returns the products available on your backend.
### Health Route
Access `<YOUR_APP_URL>/health` to get health status of your deployed backend.
### Create Admin User
[Railway’s CLI tool](https://docs.railway.app/develop/cli) allows you to run commands locally, but using environment variables from your projects.
To create an admin user in your deployed backend, run the following commands in the root of your Medusa project.
Install the CLI tool as follows:
```bash
npm i -g @railway/cli
```
Login into your Railway account:
```bash
railway login --browserless
```
This will print a URL and a Pairing Code to the Terminal, which you can use to authenticate your CLI session. Follow the instructions to complete the authentication process.
Associate your Medusa server project, environment and service with your current directory:
```bash
railway link
```
Run this to create an admin
```bash
railway run npx medusa user --email prodadmin@medusa-test.com --password supersecret
```
## Deploy Medusa Admin
We will deploy the Medusa Admin application on Cloudflare Pages.
### Create GitHub Repo
Hosting providers like Cloudflare allow you to deploy your project directly from GitHub. This makes it easier for you to push changes and updates without having to manually trigger the update in the hosting provider.
> **NOTE:**
>
>*Even though you are just deploying the admin, you must include the entire Medusa backend project in the deployed repository. The build process of the admin uses many of the backend's repos.*
Navigate to the Medusa server directory `my-medusa-store` of your project folder in your local machine. Duplicate the directory and create a new GitHub repo based on this directory to handle all the config related to the admin only.
### Configure Build Command
In the `package.json` file of your new Medusa Admin repo, add or change the build script for the admin:
```json
"scripts": {
//other scripts
"build:admin": "medusa-admin build --deployment",
}
```
> **NOTE:**
>
> When using `--deployment` option, the backend's URL is loaded from the `MEDUSA_ADMIN_BACKEND_URL` environment variable. You will configure this environment variable in a later step.
### Preparing Deployment
Log in to your [Cloudflare Dashboard](https://dash.cloudflare.com/) and select **Workers & Pages**.
Select **Create application** then **Pages** then **Connect to Git**.
You will be prompted to sign in with your preferred Git provider.
Next, select the GitHub project for your Medusa Admin repo.
Once you have selected a repository, select **Install & Authorize** and **Begin setup**.
You can then customize your deployment in **Set up builds and deployments**.
Your **project name** will be used to generate your project's hostname.
### Configure Build settings
Set the build command of your deployed project to use the `build:admin` command:
```bash
npm run build:admin
```
Set the output directory of your deployed project to `build`.
Add the environment variable `MEDUSA_ADMIN_BACKEND_URL` and set its value to the URL of your deployed Medusa backend, that is the URL you got in the previous step on Railway.
### Save Configuration and Deploy Admin
After you have finished setting your build configuration, select **Save and Deploy**. Your project build logs will output as Cloudflare Pages installs your project dependencies, builds the project, and deploys it to Cloudflare’s global network.
When your project has finished deploying, you will receive a unique URL to view your deployed site.
### Configure CORS on the Deployed Backend
To send requests from the admin dashboard to the Medusa backend, you must set the `ADMIN_CORS` environment variable on your backend to the admin's URL:
```
ADMIN_CORS=<ADMIN_URL>
```
Visit your Railway dashboard click on the GitHub repo card and choose the **Variables** tab to your deployed Medusa backend web service. Update the `ADMIN_CORS` environment variable.
Where `<ADMIN_URL>` is the URL of your admin dashboard that you just deployed on Cloudflare.
Then, redeploy your Medusa backend. Once the backend is running again, you can use your admin dashboard.
### Log into Medusa Admin Dashboard
Visit the URL to your Medusa Admin and log in using the user you created in the previous steps.
If all is working you should be able to log in to your dashboard and see all the orders you made previously when testing the development version of your store.
## Deploy Storefront
We will deploy the Sveltekit storefront on Cloudflare Pages.
### Create GitHub repo
In your local machine, navigate to the folder, `storefront` containing your Sveltekit storefront source code. Duplicate the directory and create a new GitHub repo based on this directory.
### SvelteKit Cloudflare Configuration
To use SvelteKit with Cloudflare Pages, you need to add the [Cloudflare adapter](https://kit.svelte.dev/docs/adapter-cloudflare) to your application.
Install the Cloudflare Adapter in the root of your SvelteKit `storefront` folder by running:
```bash
npm i --save-dev @sveltejs/adapter-cloudflare
```
Include the adapter in `svelte.config.js`:
```js
import adapter from '@sveltejs/adapter-cloudflare';
/** @type {import('@sveltejs/kit').Config} */
const config = {
kit: {
adapter: adapter(),
}
};
export default config;
```
Push the changes you made in your repo to GitHub.
### Prepare Deployment via Cloudflare Dashboard
Log in to your [Cloudflare Dashboard](https://dash.cloudflare.com/) and select **Workers & Pages**.
Select **Create application** then **Pages** then **Connect to Git**.
You will be prompted to sign in with your preferred Git provider.
Next, select the GitHub project for your Sveltekit storefront repo.
Once you have selected a repository, select **Begin setup**.
### Configure Build Settings
You can then customize your deployment in **Set up builds and deployments**.
Your **project name** will be used to generate your project's hostname.
Select the new GitHub repository that you created and, in **Set up builds and deployments**, provide the following information:
|Configuration Option|Value|
|---|---|
|Production branch|`main`|
|Framework preset|`SvelteKit`|
|Build command|`npm run build`|
|Build directory|`.svelte-kit/cloudflare`|
Add the environment variables, `PUBLIC_STRIPE_KEY` for your Stripe Key and `MEDUSA_BACKEND_URL` for your Railway Medusa backend server URL.
Optionally, you can customize the **Project name** field. It defaults to the GitHub repository's name, but it does not need to match. The **Project name** value is assigned as your `*.pages.dev` subdomain.
### Save Configuration and Deploy Storefront
After completing the configuration, click the **Save and Deploy** button.
You will see your first deploy pipeline in progress. Pages installs all dependencies and builds the project as specified.
Cloudflare Pages will automatically rebuild your project and deploy it on every new pushed commit.
Additionally, you will have access to [preview deployments](https://developers.cloudflare.com/pages/configuration/preview-deployments/), which repeat the build-and-deploy process for pull requests. With these, you can preview changes to your project with a real URL before deploying them to production.
When your project has finished deploying, you will receive a unique URL to view your deployed site.
### Configure CORS on the Deployed Backend
To send requests from the admin dashboard to the Medusa backend, you must set the `STORE_CORS` environment variable on your backend to the admin's URL:
```
STORE_CORS=<STORE_URL>
```
Visit your Railway dashboard click on the GitHub repo card and choose the **Variables** tab to your deployed Medusa backend web service. Update the `STORE_CORS` environment variable.
Where `<STORE_URL>` is the URL of your Sveltekit storefront that you just deployed on Cloudflare.
Then, redeploy your Medusa backend. Once the backend is running again, you can use your storefront.
### Test Storefront
Visit the URL to your storefront in your browser. If all is working your storefront home page should appear with all the products from the Medusa backend.

Here is how it works in detail:
1️⃣ Smart Contract Guarantee
BitPower Loop uses smart contract technology to automatically execute all lending transactions. This automated execution eliminates the possibility of human intervention and ensures the security and transparency of transactions. All transaction records are immutable and publicly available on the blockchain.
2️⃣ Decentralized Lending
On the BitPower Loop platform, borrowers and suppliers borrow directly through smart contracts without relying on traditional financial intermediaries. This decentralized lending model reduces transaction costs and provides participants with greater autonomy and flexibility.
3️⃣ Funding Pool Mechanism
Suppliers deposit their crypto assets into BitPower Loop's funding pool to provide liquidity for lending activities. Borrowers borrow the required assets from the funding pool by providing collateral (such as cryptocurrency). The funding pool mechanism improves liquidity and makes the borrowing and repayment process more flexible and efficient. Suppliers can withdraw assets at any time without waiting for the loan to expire, which makes the liquidity of BitPower Loop contracts much higher than peer-to-peer counterparts.

The interest rates of the BitPower Loop platform are dynamically adjusted according to market supply and demand. Smart contracts automatically adjust interest rates according to current market conditions to ensure the fairness and efficiency of the lending market. All interest rate calculation processes are open and transparent, ensuring the fairness and reliability of transactions.
5️⃣ Secure asset collateral
Borrowers can choose to provide crypto assets as collateral. These collaterals not only reduce loan risks, but also provide borrowers with higher loan amounts and lower interest rates. If the value of the borrower's collateral is lower than the liquidation threshold, the smart contract will automatically trigger liquidation to protect the security of the fund pool.
6️⃣ Global services
Based on blockchain technology, BitPower Loop can provide lending services to users around the world without geographical restrictions. All transactions on the platform are conducted through blockchain, ensuring that participants around the world can enjoy convenient and secure lending services.
7️⃣ Fast Approval and Efficient Management
The loan application process has been simplified and automatically reviewed by smart contracts, without the need for tedious manual approval. This greatly improves the efficiency of borrowing, allowing users to obtain the funds they need faster. All management operations are also automatically executed through smart contracts, ensuring the efficient operation of the platform.
Summary

1,915,724 | Strategies for Managing Test Anxiety During Online English Certification Exams | Introduction Test anxiety is a pervasive issue that affects countless students preparing... | 0 | 2024-07-08T12:21:57 | https://dev.to/danieldavis/strategies-for-managing-test-anxiety-during-online-english-certification-exams-3ljo | ## Introduction
Test anxiety is a pervasive issue that affects countless students preparing for critical exams. Imagine sitting in front of your computer, heart racing and palms sweating, as you face your online English certification exam. This stress is not uncommon, but it can be effectively managed with the right strategies. English certification exams are vital for academic and professional advancement, but the anxiety they provoke, especially in an online setting, can be overwhelming. This article will delve into comprehensive strategies to manage and reduce test anxiety for online English certification exams, ensuring you perform at your best.
## Understanding Test Anxiety
Test anxiety manifests in various ways, including physical symptoms like sweating, nausea, and a racing heartbeat, emotional responses such as fear, panic, and a sense of dread, and cognitive issues like negative thoughts, difficulty concentrating, and mental blocks. Online exams bring additional challenges, such as potential technical issues, unfamiliar formats, and the absence of a physical proctor, which can exacerbate anxiety. For instance, a student might feel overwhelmed by the possibility of their internet connection failing during the test or might struggle to navigate the digital interface smoothly.
## Preparation Strategies
Proper preparation is key to reducing test anxiety. Academically, it is crucial to thoroughly understand the exam format and content. Familiarity with the types of questions and sections in the exam can significantly reduce anxiety. For example, knowing that the exam includes a reading comprehension section, a writing task, and multiple-choice questions allows you to tailor your study approach accordingly. Regular practice with sample tests (you can find one at [https://testizer.com/tests/english-proficiency-test-online/](https://testizer.com/tests/english-proficiency-test-online/)) and past exams helps build familiarity and confidence. Setting a study schedule that covers all topics systematically, avoiding last-minute cramming, can make a significant difference.
Technically, it is essential to become comfortable with the online platform. Spend time navigating the interface, understanding how to submit answers, and familiarizing yourself with any tools provided, such as a digital timer or highlighter. Ensuring your internet connection is stable and your computer is in good working condition is also crucial. Have backups, such as an alternate device or location, in case of technical issues. For instance, if your laptop fails, having a tablet ready as a backup can be a lifesaver.
## Psychological Strategies
Managing test anxiety also involves psychological preparation. Cognitive behavioral techniques are particularly effective. Start by identifying and challenging negative thoughts that contribute to anxiety. For instance, if you catch yourself thinking, "I’m going to fail this exam," counter it with a positive affirmation like, "I have prepared well, and I will do my best." Visualization exercises, where you picture yourself successfully completing the exam, can also build confidence.
Relaxation techniques are invaluable in managing anxiety. Deep breathing exercises can calm your nervous system. Practice inhaling deeply through your nose, holding your breath for a few seconds, and then exhaling slowly through your mouth. Progressive muscle relaxation, which involves tensing and then relaxing different muscle groups, can help reduce physical tension. Mindfulness and meditation practices, focusing on the present moment, can keep your mind clear and focused.
A healthy lifestyle plays a significant role in managing anxiety. Ensure you get adequate sleep and eat balanced meals, particularly before the exam. Regular physical exercise can reduce stress and improve mental clarity. Avoid excessive caffeine and sugar intake, as these can increase anxiety and negatively impact your performance.
## Strategies During the Exam
Effective strategies during the exam are crucial. Time management is key. Break down the exam into sections and tackle them one at a time. This makes the task seem less daunting. Monitor your time without obsessing over the clock, ensuring you stay on track without adding pressure.
Develop coping mechanisms for moments when anxiety spikes. If permitted, take brief breaks to stretch and relax. Utilize relaxation techniques, such as deep breathing or mindfulness, if you start feeling overwhelmed. Stay focused on the current question, avoiding the temptation to worry about previous or future ones.
## Post-Exam Strategies
After the exam, reflect on the experience positively, without self-criticism. Consider what went well and what could be improved for next time. Seek feedback to identify areas for improvement and maintain a positive outlook for future exams. Remember, each exam is a learning experience.
## Additional Resources
There are numerous online platforms and apps designed to help with test preparation and anxiety management. For example, apps like Headspace and Calm offer guided meditation and mindfulness exercises. Exam Prep Coach provides structured study plans and practice questions. Support groups and forums can provide a sense of community and additional tips. If anxiety is significantly impacting your life, consider seeking professional help from counseling services or mental health resources.
## Conclusion
Managing test anxiety is crucial for performing well in online English certification exams. By preparing academically and technically, using psychological strategies, and employing effective time management and coping mechanisms during the exam, you can reduce anxiety and boost your performance. Consistency in applying these strategies is key to long-term success. With these tools, you can approach your exams with confidence and calm.
## FAQs
**Q: What should I do if I experience technical issues during the online exam?**
A: If you encounter technical problems, stay calm and contact technical support immediately. Inform the exam proctor about the issue if there's one available. Having a backup device or an alternate internet connection can also help mitigate such situations.
**Q: How can I improve my time management during the exam?**
A: Practice with timed sample tests to get a feel for the pacing. During the exam, break it into manageable sections and allocate specific time blocks for each. Use a clock to monitor your progress without getting distracted.
**Q: What if my anxiety is overwhelming despite using these strategies?**
A: If your anxiety remains overwhelming, consider seeking help from a mental health professional. They can provide personalized strategies and support to manage your anxiety effectively, possibly incorporating therapy or medication as needed.
**Q: Are there specific apps that can help with test anxiety?**
A: Yes, apps like Headspace and Calm offer relaxation and mindfulness exercises that can reduce anxiety. Exam Prep Coach provides structured study plans and practice questions to help you prepare more effectively. Exploring these resources can help you find the ones that best suit your needs.
**Q: How important is physical exercise in managing test anxiety?**
A: Regular physical exercise is very important as it helps reduce stress, improve mood, and enhance overall mental health, which can contribute to better exam performance. Incorporate activities you enjoy, such as jogging, yoga, or even brisk walking, into your routine.

Here is how it works in detail:
1️⃣ Smart Contract Guarantee
BitPower Loop uses smart contract technology to automatically execute all lending transactions. This automated execution eliminates the possibility of human intervention and ensures the security and transparency of transactions. All transaction records are immutable and publicly available on the blockchain.
2️⃣ Decentralized Lending
On the BitPower Loop platform, borrowers and suppliers borrow directly through smart contracts without relying on traditional financial intermediaries. This decentralized lending model reduces transaction costs and provides participants with greater autonomy and flexibility.
3️⃣ Funding Pool Mechanism
Suppliers deposit their crypto assets into BitPower Loop's funding pool to provide liquidity for lending activities. Borrowers borrow the required assets from the funding pool by providing collateral (such as cryptocurrency). The funding pool mechanism improves liquidity and makes the borrowing and repayment process more flexible and efficient. Suppliers can withdraw assets at any time without waiting for the loan to expire, which makes the liquidity of BitPower Loop contracts much higher than peer-to-peer counterparts.
4️⃣ Dynamic interest rates
The interest rates of the BitPower Loop platform are dynamically adjusted according to market supply and demand. Smart contracts automatically adjust interest rates according to current market conditions to ensure the fairness and efficiency of the lending market. All interest rate calculation processes are open and transparent, ensuring the fairness and reliability of transactions.
5️⃣ Secure asset collateral
Borrowers can choose to provide crypto assets as collateral. These collaterals not only reduce loan risks, but also provide borrowers with higher loan amounts and lower interest rates. If the value of the borrower's collateral is lower than the liquidation threshold, the smart contract will automatically trigger liquidation to protect the security of the fund pool.
6️⃣ Global services
Based on blockchain technology, BitPower Loop can provide lending services to users around the world without geographical restrictions. All transactions on the platform are conducted through blockchain, ensuring that participants around the world can enjoy convenient and secure lending services.
7️⃣ Fast Approval and Efficient Management
The loan application process has been simplified and automatically reviewed by smart contracts, without the need for tedious manual approval. This greatly improves the efficiency of borrowing, allowing users to obtain the funds they need faster. All management operations are also automatically executed through smart contracts, ensuring the efficient operation of the platform.
Summary
BitPower Loop provides a safe, efficient and transparent lending platform through its smart contract technology, decentralized lending model, dynamic interest rate mechanism and global services, providing users with flexible asset management and lending solutions.

It requires the... | 0 | 2024-07-08T12:26:16 | https://dev.to/avles/prism-a-holistic-framework-for-building-high-performance-software-delivery-teams-8n4 | ## Background <br>
Building high-performance, resilient teams is no accident. It requires the right foundational capabilities, behaviors, and processes to produce the best outcomes. Regrettably, there is no definitive playbook for building high-performing teams.
DevOps Research and Assessment (DORA) has attempted to measure software delivery performance using a few metrics. While these metrics provide some insights, they focus narrowly on software delivery aspects, potentially overlooking other crucial factors in building, collaborating, delivering, and operating software in production.
Having worked with diverse organizations—including product companies, startups, large banks, and governments—I have seen the common challenges they face. Drawing on this experience, I developed a framework to evaluate development teams' maturity and introduce foundational practices to build high-performing teams.
Introducing PRISM: Performance and Resilience Index for Software-delivery Maturity.
## Introduction
PRISM is a comprehensive framework designed to evaluate and enhance the maturity and performance of software delivery teams. It stands on seven key pillars: Team Organization, Developer Enablement, Delivery Flow, Rugged Score, Chaos Tolerance, Ops Capability, and Elasticity Score.
By assessing these core areas, PRISM can provide actionable insights and metrics to guide teams toward achieving high performance and resilience in software delivery.
PRISM comes with:
A framework to guide the incorporation of foundational capabilities
A scorecard to assess team maturity
A set of metrics for ongoing team performance evaluation
These components work together to generate a comprehensive PRISM Score.
### The Seven Pillars of PRISM<br><br>
### 1. Team Organization
Effectiveness in managing work from requirements to delivery, with a clear engagement model, appropriate governance, and ensure balance between burn and value delivered is acceptable.

Blockchain technology is one of the revolutionary innovations in the field of financial technology in recent years, which has greatly changed the traditional financial model. As an innovator in the blockchain field, BitPower has launched a series of blockchain-based decentralized finance (DeFi) solutions, especially in lending and liquidity provision, and has achieved remarkable results.
BitPower relies on the transparency, security and decentralization features of blockchain technology to establish a completely decentralized lending platform - BitPower Loop. The platform runs on Binance Smart Chain (BSC) and utilizes smart contracts to achieve automation and immutability of all transactions. Through BitPower Loop, users can conduct decentralized lending safely and conveniently, and enjoy real-time market interest rates and flexible asset mortgage services.
The core of BitPower Loop lies in its market liquidity pool model, in which users can participate as fund suppliers or borrowers. Fund providers earn income by depositing assets into smart contracts, while borrowers can use encrypted assets as collateral for loans and enjoy low-interest borrowing services. All operations are automatically executed through smart contracts, ensuring transparency and security of transactions.
In addition, BitPower has also greatly motivated users to participate by introducing new Circulation Returns and Referral Rewards mechanisms. Users can obtain daily or long-term high returns by providing liquidity, while receiving additional referral rewards by inviting new users to join the platform. These reward mechanisms not only increase users’ income sources, but also promote the rapid development of the platform ecosystem.
In terms of security, BitPower adopts multiple protection mechanisms to ensure the safety of user assets. All transaction records are open and transparent, can be queried on the blockchain, and cannot be tampered with by anyone. In addition, the non-tamperability of smart contracts ensures the stability and reliability of platform operation. Even the founder of the platform cannot change the content of smart contracts.
In general, BitPower takes advantage of blockchain technology to create a fair, secure and efficient decentralized financial platform, providing convenient financial services to users around the world. Through BitPower, users can not only enjoy the convenience brought by financial technology, but also obtain generous benefits by participating in the platform ecosystem, truly realizing the value of blockchain technology in the financial field. @Bitpower | pingz_iman_38e5b3b23e011f | |

These networks are prime targets for cybercriminals, but a VPN encrypts your data and online actions, shielding sensitive information like passwords, apps and personal communications from prying eyes. A mobile VPN also provides access to region-restricted content by masking your location, a handy perk for accessing restricted streaming services and online content while traveling.
As a business tool, a mobile VPN plays an essential role in securing the online activity of remote workers. A mobile VPN creates a secure tunnel for data transmission wherever employees connect to the internet, including unsecured networks such as public Wi-Fi. This helps preserve sensitive business information from potential breaches and allows employees to securely access corporate resources from various locations while protecting proprietary information. | franklin_newton_768fc3108 | |
1,915,737 | Mathematics for Machine Learning - Day 1 | Introduction and why I started Today will mark the first day of many on my journey to... | 27,993 | 2024-07-08T12:23:12 | https://www.pourterra.com/blogs/1 | beginners, learning, machinelearning, tutorial | ## Introduction and why I started
Today will mark the first day of many on my journey to not only use machine learning models, but understand it on a fundamental level. I've used machine learning for around a two years and yet, if you give me a pen and paper, I couldn't write down the formulas for my loss functions or my activation functions. After some reflection, I received this brutal but necessary insight from my large language model:
> You've become complacent with superficial proficiency, relying on tools without understanding their core principles. This is the mindset of an amateur, not a professional. You’re walking on thin ice, ignorant of the depths below. This isn't sustainable.
So as a person with geophysics background, I'll always welcome more mathematics than geology (Sorry geologists) and with more and more improvements in artificial intelligence it's hard to stay rooted and understand on a deeper level how does it all actually work.
The Book _Mathematics of Machine Learning_ described it best:
> As machine learning becomes more ubiquitous and its software packages become easier to use, it is natural and desirable that the low-level technical details are abstracted away and hidden from the practitioner.
### Pre-requisites:
To fully understand machine learning, there are three things to master:
1. Programming languages and data analysis tools
2. Large-scale computation and the associated frameworks
3. Mathematics and statistics and how machine learning builds on it.
---
## Chapter 1 (Mathematical Foundations)
What is machine learning?
Machine learning is designing algorithms to automatically extract valuable information from data, with strong emphasis on _automatic_
### Core of machine learning
There are three cores in machine learning, data, model, and learning.
#### Data
Machine learning is inherently data driven, to design general purpose methodologies to extract valuable information from data.
In this book, data is assumed to always be numeric so any qualitative data is processed, be it with scikit-learn's OneHotEncoder (or if I'm really lazy, a for loop with enumerate in it). So data is always seen as vectors.
##### What's a vectors?
1. An array of numbers (Computer Science)
2. An array with direction and magnitude (Physics)
3. An object that obeys addition and scaling (Mathematics)
#### Model
To extract valuable information from the data, we need to create structures/system in place that typically related to the process that generated said data. A good model can be seen as a simpler version of real (unknown) data generation.
#### Learning
The most crucial part: a model is said to learn from data when its performance on a given task improves after considering the data. Learning can be understood as a way to automatically find patterns and structures in data by optimizing the model's parameters.
## Where's the mathematics?
The mathematics is found in the four pillars of machine learning.
1. Regression
2. Dimensionality Reduction
3. Density Estimation
4. Classification
These common classes in Python’s machine learning libraries will be my focus on this journey. With the foundational principles of these pillars explained in detail in this book, I will distill this information and continue learning not just the material, but also how to communicate it effectively.

1,915,738 | How to Transition from a Generalist to a Specialist in Cloud Computing: My Journey Through the Cloud Resume Challenge | After three years of my CS degree, I explored every field I could specialize in. From web... | 0 | 2024-07-08T12:24:57 | https://dev.to/jawadshahid07/how-to-transition-from-a-generalist-to-a-specialist-in-cloud-computing-my-journey-through-the-cloud-resume-challenge-371n | aws, cloud, cloudcomputing, career |
After three years of my CS degree, I explored every field I could specialize in. From web development to machine learning, Java to C++, you could name anything, and I would tell you about a project I had made revolving around that particular thing. At this point in my life, I had become a jack of all trades, master of none. Why was that? The answer to that is simple. I couldn't settle on a field.
Until I found out about the cloud, I didn't make much of it. It's another field I'd explore and eventually lose direction in. Plus, 'cloud computing' sounds like just about the most complex field ever. But I decided to take a step forward and get into it. I discovered that AWS has the largest market share of the three largest cloud providers, and I decided to start with AWS.
So what next? Certifications?
From my three years of studying computer science, if there was one thing I learned, it was this: to learn something, you have to get your hands dirty. That's right, hands-on work. I had to make projects. In the past, I've taken courses that contain 50+ hours of videos each, only to decide I don't want to be doing that in the future. Moreover, those videos wouldn't teach me more than theory; I had to do a project to truly understand anything.
So, eventually, I found the cloud resume challenge, labeled as the entry point for beginners trying to get into the cloud. It immediately caught my attention. I got my hands on the AWS edition book and had no idea what I was getting into. I can say now that it was a life-changing experience.
After completing the cloud resume challenge, here is my journey.
**You may access my resume website here:** [jawadify.xyz](jawadify.xyz)
**Prerequisites:**
The initial requirement of the cloud resume challenge was to acquire the foundational Cloud Certified Practitioner Certification. However, this step was optional. As I already had an IT background, I skipped this step. My goal was to do hands-on work before I started studying for certifications.
**Part 1: Building the front-end**
The first step of this part was simple: making a resume in HTML and CSS. I already had ample experience doing this, so I did the additional developer mod. I made the front end using React instead of simple HTML and CSS. Moreover, since I had recently updated it, I could replicate the exact resume I usually hand out to recruiters. What better way to say to someone asking for your resume, "Go to this website," and have the exact resume printed on their screen?
The next step, however, was much trickier. At this point, I started feeling the lack of cloud knowledge I had, perhaps from skipping the CCP certification. I was lost. Static S3 website CloudFront, Route 53? I had no idea what to do. I decided to pause to learn more about the cloud and cloud development. I started reviewing the [AWS docs](https://docs.aws.amazon.com/) and YouTube tutorials explaining AWS and the cloud and completed an [Introduction to Cloud 101](https://awseducate.instructure.com/courses/891) course by AWS Educate. Eventually, I cracked this part and could access my resume from anywhere using the internet. I thought I had done all the work, but it was just the start!
**Part 2: Building the API**
At this stage, things became more advanced. Thankfully, I had previous experience with developing APIs, and even though the boto3 library was new to me, I went back to the docs to gain guidance so I could set up my Lambda function using Python. Once again, I struggled to navigate the cloudy stuff, but the AWS docs helped. As for source control, I had set up my GitHub repository from the start, so I just pushed the changes.
It took some going back and forth, though, as I had to spend some time testing the API to make sure it was doing what I wanted. There were few lines of code compared to what I have done before, but the errors, especially those CORS errors, made me question whether cloud computing suits me. After I went into the developer console on my browser, I discovered that they were the cause of all my problems.
**Part 3: Front-End/Back-End Integration**
I had to write my JavaScript code to display the visitor count on my resume, utilizing the call to my API. To do that, I also had to set up an API gateway to my lambda function. After this, I wrote some tests in Python to make sure my API was working properly. I wrote unit tests, integration tests, and end-to-end tests. I had some experience in Selenium, so this time, I chose to try out [puppeteer](https://pptr.dev/), doing something new.
I also wrote a test that directly called the API to ensure it was correct by comparing the values from the first and second calls.
**Part 4: Automation / CI**
The good part was that Infrastructure as Code (IaC) was the first thing I set up at the start of this challenge. I used AWS SAM, which was the one mentioned in the challenge. Working with IaC opened me up to the actual world of the cloud. It is truly magical that I could delete all the work I have done on the cloud by using one command and deploying it all again with all my settings with another command. IaC is where it's really at.
I already had all my SAM code on the GitHub repository; my front end was with it. I chose to keep it as one repository rather than two for simplicity. I was already working with makefile to make my deployment effortless, but then I realized the magic of GitHub actions. I made a workflow template and, within it, created a bunch of jobs. One job was to test the code; another was to build my infrastructure, another was to deploy my site, and so on.
**Conclusion**
At last, my website was complete. I developed a complete end-to-end project from front-end to back-end, testing through CI/CD and automation. I don't believe I've ever made a project that was so complete. It touched on everything you'd do when developing a project, and it felt extremely satisfying.
One thing was clear, though: I learned a lot. In the beginning, I struggled to make an AWS account and assign it permissions through IAM, which I needed to figure out what to make of. Now, I feel confident in my AWS skills. I could easily navigate the console, know what to do and where to go and build and deploy resources using code with an IaC tool.
Now, I have started out pursuing my cloud journey. I did the project, and I found out what cloud computing is. I decided that this was it. Cloud engineering was what I wanted to be doing in the future. Therefore, I will now work on doing more projects and pursue the Solutions Architect Associate Certification to have an all-rounded cloud portfolio by next year, when I will start applying for a cloud role.

1,915,739 | Explore how BitPower Loop works | BitPower Loop is a decentralized lending platform based on blockchain technology that aims to provide... | 0 | 2024-07-08T12:25:26 | https://dev.to/wgac_0f8ada999859bdd2c0e5/explore-how-bitpower-loop-works-4ba0 | BitPower Loop is a decentralized lending platform based on blockchain technology that aims to provide secure, efficient and transparent lending services. Here is how it works in detail:
1️⃣ Smart Contract Guarantee
BitPower Loop uses smart contract technology to automatically execute all lending transactions. This automated execution eliminates the possibility of human intervention and ensures the security and transparency of transactions. All transaction records are immutable and publicly available on the blockchain.
2️⃣ Decentralized Lending
On the BitPower Loop platform, borrowers and suppliers borrow directly through smart contracts without relying on traditional financial intermediaries. This decentralized lending model reduces transaction costs and provides participants with greater autonomy and flexibility.
3️⃣ Funding Pool Mechanism
Suppliers deposit their crypto assets into BitPower Loop's funding pool to provide liquidity for lending activities. Borrowers borrow the required assets from the funding pool by providing collateral (such as cryptocurrency). The funding pool mechanism improves liquidity and makes the borrowing and repayment process more flexible and efficient. Suppliers can withdraw assets at any time without waiting for the loan to expire, which makes the liquidity of BitPower Loop contracts much higher than peer-to-peer counterparts.
4️⃣ Dynamic interest rates
The interest rates of the BitPower Loop platform are dynamically adjusted according to market supply and demand. Smart contracts automatically adjust interest rates according to current market conditions to ensure the fairness and efficiency of the lending market. All interest rate calculation processes are open and transparent, ensuring the fairness and reliability of transactions.
5️⃣ Secure asset collateral
Borrowers can choose to provide crypto assets as collateral. These collaterals not only reduce loan risks, but also provide borrowers with higher loan amounts and lower interest rates. If the value of the borrower's collateral is lower than the liquidation threshold, the smart contract will automatically trigger liquidation to protect the security of the fund pool.
6️⃣ Global services
Based on blockchain technology, BitPower Loop can provide lending services to users around the world without geographical restrictions. All transactions on the platform are conducted through blockchain, ensuring that participants around the world can enjoy convenient and secure lending services.
7️⃣ Fast Approval and Efficient Management
The loan application process has been simplified and automatically reviewed by smart contracts, without the need for tedious manual approval. This greatly improves the efficiency of borrowing, allowing users to obtain the funds they need faster. All management operations are also automatically executed through smart contracts, ensuring the efficient operation of the platform.
Summary
BitPower Loop provides a safe, efficient and transparent lending platform through its smart contract technology, decentralized lending model, dynamic interest rate mechanism and global services, providing users with flexible asset management and lending solutions.

Vamos utilizar bibliotecas como azure.storage.blob e mssparkutils para interagir com o serviço de armazenamento e obter segredos do Azure Key Vault.
Configurações Iniciais
Primeiramente, precisamos definir algumas configurações iniciais, como o nome do container, o caminho relativo dos arquivos e o serviço vinculado que vamos usar.
```
`from azure.storage.blob import BlobServiceClient
import json
```
```
# Configurações iniciais
blob_container_name = 'container_aqui' # seu nome do container
blob_relative_path_enriched = 'caminho_aqui' # caminho com barra no final
linked_service_enriched = 'Linked_service_aqui' # seu linked service
`
```
Obtendo Propriedades do Key Vault
Vamos utilizar o mssparkutils para obter as propriedades do Key Vault e a chave de acesso necessária.
```
`# Obtendo propriedades do Key Vault
ls_keyvault = mssparkutils.credentials.getPropertiesAll('Linked_service_aqui')
converter_dic_kv = json.loads(ls_keyvault)
# Coletando o endpoint do Key Vault
end_point_kv = (converter_dic_kv['Endpoint'].split("/"))[2]
kv_name = (end_point_kv.split("."))[0]
# Obtendo a chave de acesso do Key Vault
access_key = mssparkutils.credentials.getSecret(kv_name, 'seu_storage_aqui', 'Linked_service_aqui')
`
```
Configurando o Cliente do Blob Storage
Agora que temos a chave de acesso, vamos configurar o cliente do Blob Storage.
```
# Obtendo propriedades do linked service
ls_enriched = mssparkutils.credentials.getPropertiesAll(Linked_service_aqui_enriched)
converter_dic_enriched = json.loads(ls_enriched)
```
```
# Coletando o endpoint do linked service
end_point_enriched = (converter_dic_enriched['Endpoint'].split("/"))[2]
```
```
# Configurando o cliente do Blob Storage
storage_account = end_point_enriched.split(".")[0]
print(f"Storage Account: {storage_account}")
print(f"Access Key: {access_key[:4]}...{access_key[-4:]}") # Mostrar apenas início e fim da chave por segurança
```
```
blob_service_client = BlobServiceClient(account_url=f"https://{storage_account}.blob.core.windows.net", credential=access_key)
container_client = blob_service_client.get_container_client(blob_container_name)
```
Função para Listar Arquivos
Vamos criar uma função para listar os nomes dos arquivos em um diretório específico no Blob Storage.
```
def list_files_in_directory(container_client, directory_path):
""" Função para listar os nomes dos arquivos em um diretório específico """
try:
print(f"Tentando acessar o container: {container_client.container_name}")
blob_list = container_client.list_blobs(name_starts_with=directory_path)
file_names = [blob.name for blob in blob_list]
if not file_names:
print(f"Nenhum arquivo encontrado em {directory_path}.")
return file_names
except Exception as e:
print(f"Erro ao listar arquivos no diretório especificado: {e}")
return []
```
Listando os Arquivos
Agora podemos usar a função list_files_in_directory para listar os arquivos no diretório especificado.
```
# Listando os nomes dos arquivos no diretório especificado
print(f"Tentando listar arquivos no diretório: {blob_relative_path_enriched}")
file_names = list_files_in_directory(container_client, blob_relative_path_enriched)
# Verificando se a lista de arquivos não está vazia
if not file_names:
print("Nenhum arquivo encontrado no diretório especificado.")
else:
# Exibindo os nomes dos arquivos
print(f"Arquivos encontrados no diretório {blob_relative_path_enriched}:")
for file_name in file_names:
print(file_name)
print("Processo finalizado.")
```
Com isto podemos listar todos os dados dentro de um blob utilizando um notebook com Synapase junto a Microsoft Azure.

and practical application. Picture machines equipped with the intelligence to
observe and interpret their environment, mirroring the discernment and
attention to detail akin to human observation. This cutting-edge technology
utilizes advanced cameras and sensors to identify and classify an extensive
variety of objects. It doesn't just recognize these items; it meticulously
evaluates their size, shape, and precise spatial location. In the logistics
sector, where handling an assortment of goods with efficiency and precision is
paramount, object detection has become a cornerstone technology. It is
redefining what it means to achieve operational excellence, turning the
ordinary into the extraordinary.
## Precision and Reliability: Redefining Excellence
In the realm of automated logistics, object detection technology has
established a new gold standard for precision. It's like comparing a skilled
craftsman's meticulous work to routine manual labor. This revolutionary
technology endows machines with the ability to not just recognize but
skillfully manage objects of various shapes and sizes. This capability is
transforming essential processes like sorting, stacking, and storage. The
impact? A substantial acceleration in workflow, a drastic reduction in
operational errors, and a significant improvement in the reliability and
consistency of logistics systems.

1,915,749 | Nest JS Guard | Introduction Dans cette publication, nous explorerons le concept des guards dans Nest.js... | 0 | 2024-07-08T12:36:04 | https://dev.to/bilongodavid/nest-js-guard-1jf7 | javascript, node, nestjs |
### Introduction
Dans cette publication, nous explorerons le concept des guards dans Nest.js et comment les utiliser pour sécuriser vos applications backend. Les guards jouent un rôle crucial en permettant ou en refusant l'accès aux routes de manière conditionnelle, en fonction des règles que vous définissez.
### Qu'est-ce qu'un Guard ?
Les guards dans Nest.js sont des classes annotées avec `@Injectable()` qui implémentent l'interface `CanActivate`. Ils sont utilisés pour protéger l'accès aux routes en fonction de certains critères comme les autorisations de l'utilisateur, l'authentification, ou d'autres conditions métier.
### Exemple de Code
Voici un exemple de base pour illustrer comment créer un guard simple dans Nest.js :
```typescript
import { Injectable, CanActivate, ExecutionContext } from '@nestjs/common';
import { Observable } from 'rxjs';
@Injectable()
export class AuthGuard implements CanActivate {
canActivate(
context: ExecutionContext,
): boolean | Promise<boolean> | Observable<boolean> {
// Logic to determine if user is authenticated
const request = context.switchToHttp().getRequest();
return !!request.user;
}
}
```
### Explication du Code
- Nous créons une classe `AuthGuard` qui implémente `CanActivate`.
- Dans la méthode `canActivate`, nous accédons à l'exécution du contexte pour vérifier si l'utilisateur est authentifié (`request.user`).
- Si l'utilisateur est authentifié, `canActivate` retourne `true`, sinon `false`.
### Utilisation dans un Contrôleur
Pour utiliser ce guard dans un contrôleur, vous pouvez l'appliquer à une route spécifique comme ceci :
```typescript
import { Controller, Get, UseGuards } from '@nestjs/common';
import { AuthGuard } from './auth.guard';
@Controller('products')
export class ProductsController {
@Get()
@UseGuards(AuthGuard)
findAll(): string {
return 'This action returns all products';
}
}
```
### Conclusion
Les guards sont essentiels pour sécuriser vos applications Nest.js, en offrant un contrôle d'accès flexible et basé sur des règles. En utilisant les guards, vous pouvez facilement implémenter des stratégies d'autorisation et d'authentification dans vos APIs.
### Prochaines Étapes
- Explorez d'autres types de guards comme `AuthGuard`, `RolesGuard`, ou créez des guards personnalisés pour répondre à des besoins spécifiques.
- Intégrez des guards avec des stratégies d'autorisation plus complexes basées sur des rôles ou des permissions.
### Ressources Additionnelles

1,915,750 | Floods Prediction in Lagos, Nigeria. | Introduction Lagos is a city on Nigeria's Atlantic Coast with a population of 16.5 million... | 0 | 2024-07-08T12:36:13 | https://dev.to/mwangcmn/floods-prediction-in-lagos-nigeria-3ici | machinelearning, python | # Introduction
Lagos is a city on Nigeria's Atlantic Coast with a population of 16.5 million people according to the UN in 2023. In the past 2 years, the city has experienced multiple flood events that have resulted in catastrophic events. The city is built on the mainland and a string of islands along the coastline. While the floods may be attributed to factors such as the rising sea levels, shoreline erosion and sand mining, it is imperative that the city implements effective disaster risk management system to deal with the effects of floods.
In this project I will implement an ARIMA model to predict when the city is likely to experience the floods.
Time series is widely used for forecasting and predicting future observations in a **time series**. AutoRegressive Intergrated Moving average models (ARIMA) are used for predicting time series data.
# Data Understanding
The data used in this analysis ranges from 1st January 2002 to 28th February 2025. This data can be found on [Visual Crossing](https://www.visualcrossing.com/weather/weather-data-services).Find a description of each variable [here](https://www.visualcrossing.com/resources/documentation/weather-data/weather-data-documentation/)
**Notes**
View notebook on [Github](https://github.com/mwang-cmn/Floods-Prediction-Lagos-/blob/main/Floods_Prediction_Lagos.ipynb)
1. The data contains 44498 records and 36 columns.
2. I renamed the 'precip' column to 'Precipitation'
3. I renamed the datetime column to Date
4. I dropped the name column and set the Date column as the index.
```
#Drop name column
data.drop(['name'], axis=1, inplace=True)
#rename datetime to DATE
data.rename(columns={'datetime': 'Date'}, inplace=True)
#Rename precip to Precipitation
data.rename(columns={'precip': 'Precipitation'}, inplace=True)
#set date to index
data.set_index('Date', inplace=True)
```
### Exploratory Data Analysis
1. A line plot showing Daily Precipitation from 2002 to 2024
2. A line plot showing Monthly Precipitation from 2002 to 2024
### ARIMA Model
An ARIMA model is defined with the notation ARIMA(p,d,q), where
p - The number of lagged observations
d - Number of differencing operations
q - The size of the moving average window
When adopting an ARIMA model,the above parameters must be specified, the time series must be made stationary via differencing and the residuals should be uncorrelated. I conducted an adfuller test that confirmed the data series to be stationary.
An ARIMA model was used to forecast future daily precipitation based on historical data. The model provided a 30-day forecast of daily precipitation for the next year. This forecast was plotted along with historical data to visualize the forecast values.
```
# Forecast the next 12 months
forecast_steps = 12
forecast = arima_model.forecast(steps=forecast_steps)
# Plot the historical data and forecast
plt.figure(figsize=(10, 6))
plt.plot(monthly_data, label='Historical')
plt.plot(forecast, label='Forecast', color='red')
plt.title('Monthly Precipitation Forecast')
plt.xlabel('Date')
plt.ylabel('Precipitation (inches)')
plt.legend()
plt.show()
```
Recall, our values in Precipitation column are in inches. Therefore, given the tropical climate in Nigeria, I set a threshhold of 200 mm or 8 inches to indicate potential of a flood.Local studies in Nigeria have shown that rainfall events exceeding 150 mm often lead to significant flooding in Lagos.
I then subset the forecasted data to obtain the next 12 periods Lagos is likely to experience floods, that is, rainfall above 8 inches or 200 mm.
```
# Set the flood threshold
flood_threshold = 8.0
# Identify months with predicted precipitation above the threshold in the future forecast
flood_months = forecast_future[forecast_future > flood_threshold]
print("Predicted flood months:")
print(flood_months)
```
### Conclusions
The ARIMA models provides a flexible and structured way to model a time series data that relies on historical observations as well as past prediction errors. Ho
**Summary of Findings**
In this study, I utilized historical rainfall data and time series techniques to predict flood occurrences in Lagos. By leveraging the ARIMA model, I generated accurate monthly precipitation forecasts. The analysis identified specific months with a high likelihood of flooding, providing valuable insights for urban planning and disaster management in Lagos.
**Key findings include:**
1. Prediction Accuracy: The ARIMA model demonstrated robust predictive capabilities, accurately forecasting rainfall trends.
2. Flood Threshold: We established a realistic flood threshold of 200 mm of rainfall within 24 hours, based on historical data and scientific literature.
3. Identified Risk Periods: Our model identified several months with predicted precipitation exceeding the flood threshold, indicating potential flood risk periods.
Implications for Stakeholders
The results of this analysis can significantly aid local authorities, urban planners, and disaster management agencies in:
1. Proactive Flood Management: Implementing early warning systems and preparedness measures during identified high-risk months.
2. Infrastructure Planning: Enhancing drainage systems and urban infrastructure to mitigate flood impacts.
3. Public Awareness: Informing and educating the public about flood risks and necessary precautions.
### Limitations
While the analysis provides valuable insights, there are several limitations to consider:
1. Data Quality and Availability: The accuracy of predictions depends on the quality and granularity of historical rainfall data.
2. Model Assumptions: The ARIMA model assumes linearity and may not capture complex, non-linear interactions in climate data.
3. External Factors: Factors such as urbanization, land use changes, and climate change were not explicitly modeled but can significantly influence flood risks.

Cześć! W tym miesiącu mamy dla Ciebie kilka nowych aktualizacji.
- Wprowadziliśmy nową flagę integralności referencyjnej, która pomaga zachować spójność danych.
- Limity grup kanałów można teraz ustawiać bezpośrednio z portalu administracyjnego.
- Spróbuj zaimportować dane z Insights do BizOps, aby przetestować jego funkcje.
- Ponadto zauważysz odświeżony wygląd i sposób działania Presence Management.
Poza tym wprowadziliśmy kilka drobnych, ale znaczących ulepszeń w dokumentacji, które, miejmy nadzieję, odpowiedzą na niektóre pytania lub rozwieją wszelkie wątpliwości podczas pracy z PubNub.
Miłego odkrywania i dziękujemy za bycie częścią naszej społeczności!
Ogólne 🛠️
----------
### Pola niestandardowe w ładunkach FCM
**Typ**: Ulepszenie
Poprawiliśmy dokumentację dla [Android Mobile Push Notifications](https://pubnub.com/docs/general/push/android#step-5-construct-the-push-payload), dodając brakujące niestandardowe parametry PubNub, które można dodać do ładunku FCM Mobile Push Notification: `pn_debug`, `pn_exceptions` i `pn_dry_run`.
Umożliwiają one testowanie lub debugowanie powiadomień oraz wykluczanie wybranych urządzeń z otrzymywania powiadomień.
Oto przykładowy ładunek FCM z naszymi niestandardowymi polami:
```js
{
"pn_fcm": {
"notification": {
"title": "My Title",
"body": "Message sent at"
},
"pn_collapse_id": "collapse-id",
"pn_exceptions": [
"optional-excluded-device-token1"
]
},
"pn_debug": true,
"pn_dry_run": false
}
```
### Limity grupy kanałów
**Typ**: Nowa funkcja
Kontroler strumienia w portalu administracyjnym ma nową, konfigurowalną opcję [limitu grupy](https://pubnub.com/docs/general/metadata/basics#configuration) kanałów dla klientów korzystających z [płatnych planów cenowych](https://www.pubnub.com/pricing/?utm_source=devto&utm_medium=syndication&utm_campaign=off_domain&utm_content=pl), która pozwala ustawić limity maksymalnej liczby kanałów, które mogą mieć grupy kanałów w zestawie kluczy. Można obniżyć domyślny limit 1000 kanałów lub zwiększyć go do 2000 kanałów.
### Zdarzenia metadanych użytkownika w kontekście aplikacji
**Typ**: Ulepszenie
Poprawiliśmy dokumentację, aby wyjaśnić, że przy włączonej opcji **User Metadata Events** każda modyfikacja jednostki użytkownika`(ustawienie` i `usunięcie`) powoduje wysłanie powiadomień o zdarzeniach do wszystkich stowarzyszeń członkowskich, a więc zarówno tego użytkownika, jak i każdego kanału, którego jest członkiem. Szczegółowe informacje można znaleźć w [dokumentacji](https://pubnub.com/docs/general/metadata/basics#app-context-events).
### Zależność konfiguracji App Context
**Typ**: Ulepszenie
Zaktualizowaliśmy dokumentację dotyczącą [opcji konfiguracji](https://pubnub.com/docs/general/metadata/basics#configuration) App Context, aby uwzględnić informacje o krytycznej zależności.
Chociaż opcje Disallow Get **All Channel Metadata** i **Disallow Get All User Metadata** wydają się dość oczywiste, zastrzeżenie polega na tym, że opcje te działają tylko z włączonym Menedżerem dostępu.
Innymi słowy, bez Menedżera dostępu te aktywne opcje nie wyłączają pobierania metadanych o użytkownikach lub kanałach na zestawie klawiszy. Jednocześnie po włączeniu Menedżera dostępu, który domyślnie ogranicza dostęp do wszystkich obiektów w zestawie kluczy, można łatwo ominąć ograniczenia GET Menedżera dostępu dla użytkowników i kanałów, usuwając zaznaczenie obu tych opcji konfiguracji bez tworzenia szczegółowego schematu uprawnień.
Interfejs użytkownika portalu administracyjnego wkrótce również odzwierciedli tę zależność.
### Nowa flaga integralności referencyjnej w App Context
**Typ**: Nowa funkcja
Dodaliśmy nową opcję [**Wymuś integralność referencyjną dla członkostwa**](https://pubnub.com/docs/general/metadata/basics#configuration), która jest domyślnie włączona po włączeniu App Context w zestawie kluczy aplikacji w portalu administracyjnym.
Flaga ta zapewnia, że można ustawić nowe członkostwo tylko wtedy, gdy istnieje zarówno identyfikator użytkownika, jak i identyfikator kanału, dla którego utworzono członkostwo. Jednocześnie usunięcie nadrzędnej jednostki metadanych użytkownika lub kanału automatycznie usuwa wszelkie podrzędne skojarzenia członkostwa dla tej usuniętej jednostki. W ten sposób można upewnić się, że w zestawie kluczy nie ma nieprawidłowo działających lub osieroconych obiektów członkowskich.
SDK 📦
------
### Ulepszenia dokumentacji Python
**Typ**: Ulepszenie
Po otrzymaniu informacji zwrotnych rozszerzyliśmy informacje na temat użycia i wykonywania metod. W rezultacie każda sekcja Returns w [dokumentacji Python SDK](https://pubnub.com/docs/sdks/python/api-reference/publish-and-subscribe) opisuje teraz pola danych zwracane przez każdą metodę. Wyjaśnia również, w jaki sposób wykonanie żądania synchronicznego (`.``sync()`) i asynchronicznego (`.pn_async(callback)`) wpływa na zwracane dane dla każdej metody.
### React SDK został przestarzały
**Typ**: Powiadomienie o deprecjacji
Ponieważ od jakiegoś czasu nie rozwijamy aktywnie React SDK, zdecydowaliśmy się w końcu oficjalnie zdeprecjonować jego [dokumentację](https://pubnub.com/docs/sdks/react) i przenieść ją do sekcji [Call For Contributions](https://pubnub.com/docs/sdks#call-for-contributions) w naszych dokumentach.
Jeśli znajdziesz błąd w React SDK lub chcesz rozszerzyć jego funkcjonalność, możesz utworzyć pull request w [repozytorium](https://github.com/pubnub/react) i poczekać na naszą opinię!
Funkcje
-------
### Eksportowanie logów funkcji poprzez zdarzenia i akcje
**Typ**: Nowa funkcja
Każda funkcja PubNub zapisuje logi w wewnętrznym kanale `blocks-output-*`, takim jak `blocks-output-NSPiAuYKsWSxJl4yBn30`, który może przechowywać do 250 wierszy logów, zanim nowe je nadpiszą. Jeśli nie chcesz stracić starych dzienników, możesz teraz użyć funkcji Events & Actions, aby [wyeksportować te dzienniki](https://pubnub.com/docs/general/portal/functions#export-logs-through-events--actions) do usługi zewnętrznej.
Insights 📊
-----------
### Czas trwania użytkownika i metryki urządzeń w dokumentacji interfejsu API REST
**Typ**: Ulepszenie
[W zeszłym miesiącu](https://pubnub.com/docs/release-notes/2024/may#device-metrics-dashboard) wprowadziliśmy metryki urządzeń do pulpitu nawigacyjnego `Zachowanie użytkownika` w PubNub Insights na portalu administratora. W tym miesiącu zaktualizowaliśmy dokumentację interfejsu [API R](https://pubnub.com/docs/sdks/rest-api/introduction-16) EST, aby uwzględnić zarówno czas trwania użytkownika, jak i metryki urządzenia, dzięki czemu można bezpośrednio wywołać interfejs API PubNub Insights, aby uzyskać interesujące metryki.
BizOps Workspace 🏢
-------------------
### Top 20 użytkowników/kanałów
**Typ**: Nowa funkcja
Jeśli nie używasz App Context do przechowywania i zarządzania użytkownikami i kanałami, nadal możesz przetestować powiązane funkcje BizOps Workspace, importując dane testowe.
Jeśli masz dostęp do PubNub Insights, możesz uzyskać do niego dostęp, przechodząc do modułów **User Management** i **Channel Management** w BizOps Workspace w Admin Portal i klikając przycisk **Import from Insights**.
W rezultacie zaimportujesz z zestawu kluczy aplikacji maksymalnie 20 użytkowników, którzy opublikowali największą liczbę wiadomości w ciągu ostatniego dnia (jeśli wczoraj nie wysłano żadnych wiadomości, użytkownicy zostaną zaimportowani na podstawie danych z poprzedniego dnia).
Podobnie jak w przypadku użytkowników, można zaimportować z zestawu kluczy aplikacji do 20 kanałów z największą liczbą wiadomości opublikowanych w ciągu ostatniego dnia.
Użyj tych danych testowych, aby poznać możliwości BizOps Workspace.
### Odświeżony interfejs zarządzania obecnością
**Typ**: Ulepszenie
Niedawno przeprojektowaliśmy cały moduł zarządzania [obecnością](https://pubnub.com/docs/bizops-workspace/presence-management) w BizOps Workspace, aby uprościć kreator tworzenia reguł, zmienić kolory odznak na bardziej integracyjne i dodać konfigurację wzorca "catch all", która odzwierciedla domyślną konfigurację "włącz obecność na wszystkich kanałach" konfiguracji obecności w zestawie kluczy.
Mamy nadzieję, że spodoba ci się jego nowy wygląd! | pubnubdevrel |
1,915,753 | How to turn a Jupyter Notebook into a deployable artifact | One of the most difficult challenges for a machine learning engineering team is efficiently bringing... | 0 | 2024-07-08T12:37:32 | https://jozu.com/blog/how-to-turn-a-jupyter-notebook-into-a-deployable-artifact/ | beginners, programming, tutorial, ai | One of the most difficult challenges for a machine learning engineering team is efficiently bringing to production the considerable work done during a model's research and development stages. Often, the whole development stage of a model is done within Jupyter Notebook, a tool focused on experimentation rather than building a deployable artifact.
In this post, you’ll see how to address this challenge. For our example we will take a [LLama3 LLM](https://llama.meta.com/llama3/) model with [Lora-adapters](https://huggingface.co/docs/diffusers/en/training/lora) that was fine-tuned in a Jupyter Notebook, and then turn it into a deployable artifact using [KitOps](https://kitops.ml/) and [ModelKit](https://kitops.ml/#howdoesitwork). This artifact will become a pod deployed in a Kubernetes cluster.
## Why is a Jupyter Notebook not directly deployable to production?
A [Jupyter Notebook](https://jupyter.org/) is a web-based interactive tool that allows you to create a computational environment to produce documents containing code and rich text elements. This is the standard tool for research and development of a new machine learning model or a new fine-tuning methodology because Jupyter Notebook is focused on:
- The immediate observation of results. It is enabled by the interactive execution of code within designated cells. This facilitates an iterative problem-solving approach and experimentation.
- Containing the entire computational workflow, including the code, explanations, and outputs. This characteristic promotes the replicability and dissemination of research ideas.
- Collaboration with colleagues, fostering collaborative efforts, and exchanging knowledge.
While the Jupyter Notebook is the right tool for data exploration and prototyping, it is generally not ideal for direct deployment in production for a few reasons:
- The code execution order is not linear because cells can be executed in any order, which can lead to a non-linear flow of logic and hidden state (variables that change within the notebook). This makes it difficult to understand how the code works and troubleshoot issues in production.
- Notebooks are often single-threaded and not designed to handle high volumes of traffic. It wouldn't perform well in applications requiring real-time responsiveness or work efficiently across multiple nodes or clusters.
- Notebooks can execute arbitrary code and often contain sensitive information, raw code, and data, which can be a security vulnerability if not properly managed.
- Logging, monitoring, and integration with other systems are common in production environments, and Notebooks are not built for this type of integration.
There are many ways to deploy the model developed within your Jupyter Notebook, depending on the needs and team skills. However, in this article, we will walk you throughthe deployment of a Kubernetes init container using KitOps and ModelKit.
## What are the stages to bring your model to production?
Using Jupyter Notebook, you can develop and/or fine-tune an AI/ML model, but a model needs to pass through specific stages before being deployed to production. For each stage, the whole team (data scientists, ML engineers, SRE) requires artifacts that can be immutable, secure, and shareable.
KitOps and ModelKits, an OCI-compliant packaging format, are designed to respond to this need. ModelKit standardizes how all necessary artifacts, including datasets, code, configurations, and models, are packaged, making the development process simpler and more collaborative.
The stages of the development process for an ML model are:
- **Untuned:** This is the stage where the dataset is designed for model tuning and model validation. At this stage, the ModelKit contains only datasets and the base model; for example, LLama3 instructs quantized 4.
- **Tuned:** At this stage, the model has completed the training phase. ModelKit would include the model, plus training and validation datasets, the Jupyter Notebook with the code for the fine-tuning, and other assets for the specific use case, like Lora-adapters for the LLM fine-tuning.
- **Challenger:** The model should be prepared to replace the current champion model. ModelKit would include any codebases and datasets that should be deployed to production with the model.
- **Champion:** The model is deployed in production. This is the same ModelKit as the challenger-tagged one but with an updated tag to show what's in production.
Next, you’ll see the step-by-step process of implementing these stages and creating immutable artifacts with Kitops.
## Stage 1: Create the untuned ModelKit
To begin, create a project folder named llama3-finetune. Within this folder, create two subfolders: one for datasets and another for notebooks. If you haven’t installed the Kit CLI, follow this [guide](https://kitops.ml/docs/quick-start.html#before-we-start) to install it.
Open your shell and download the LLama3 8 billion parameters, which will be fine-tuned from ModelKit:
kit login ghcr.io
kit unpack ghcr.io/jozu-ai/llama3:8B-instruct-q4_0
Another file is created in your folder: Kitfile. This is the manifest for your ModelKit and a set of files or directories, including adapters, a Jupyter Notebook, and a dataset.
Next, you are ready to embark on the first step of your MLOps pipeline: creating the dataset for training. If your goal is to fine-tune an open-source large language model like LLama3 for a chat use case, a widely used dataset is the [HuggingFace ultrachat_200K](https://huggingface.co/datasets/HuggingFaceH4/ultrachat_200k).
Install the datasets package and download the dataset in a new Jupyter Notebook called finetune.ipynb:
#install necessary packages:
!pip install datasets
#Download the dataset:
from datasets import load_dataset
ds = load_dataset("HuggingFaceH4/ultrachat_200k")
Starting from this dataset, develop the code to adapt it for your particular use case.
In this use case, the dataset will be converted with the chat template; first, you need to install the transformers package:
#install necessary packages:
!pip install transformers
In the next cell of your Jupyter Notebook, use the `apply_chat_template` to create the train and test datasets for the chat use case:
import os
from transformers import AutoTokenizer
model_id = 'AgentPublic/llama3-instruct-8b'
train_dataset = ds['train_gen']
test_dataset = ds['test_gen']
tokenizer = AutoTokenizer.from_pretrained(model_id)
def format_chat_template(row):
chat = tokenizer.apply_chat_template(row["messages"], tokenize=False)
return chat
os.makedirs('../dataset', exist_ok=True)
with open('../dataset/train.txt', 'a', encoding='utf-8') as f_train:
for d in train_dataset:
f_train.write(format_chat_template(d))
with open('../dataset/test.txt', 'a', encoding='utf-8') as f_test:
for d in test_text:
f_test.write(format_chat_template(d))
The datasets (train and test) are saved in the `./dataset` folder.
The structure of your project is now something like this:
- llama3-finetune
|-- dataset
|-- train.txt
|-- test.txt
|-- notebooks
|-- finetune.ipynb
|-- kitfile
|-- llama3-8B-instruct-q4_0.gguf
At this point, you need to change the kitfile to package everything you need in the following stages:
manifestVersion: "1.0"
package:
name: llama3 fine-tuned
version: 3.0.0
authors: [Jozu AI]
code:
- description: Jupyter notebook with dataset creation
path: ./notebooks
model:
name: llama3-8B-instruct-q4_0
path: ghcr.io/jozu-ai/llama3:8B-instruct-q4_0
description: Llama 3 8B instruct model
license: Apache 2.0
datasets:
- description: training set from ultrachat_200k
name: training_set
path: ./dataset/train.txt
- description: test set from ultrachat_200k
name: test_set
path: ./dataset/test.txt
The kitfile can now be pushed to your Git repository, and you can tag this commit as `untuned,` the same tag as the ModelKit. In your terminal, write:
kit pack /llama2_finetuning -t registry.gitlab.com/internal-llm/llama3-ultrachat-200k:untuned
kit push registry.gitlab.com/internal-llm/llama3-ultrachat-200k:untuned
## Step 2: Fine-tune the model
The second stage is to fine-tune the model in the Jupyter Notebook, developing the code to perform this. For an LLM, one possible solution is to fine-tune the lora-adapters with [llama.ccp](https://github.com/ggerganov/llama.cpp) as shown below:
# finetune LORA adapter
./bin/finetune \\
--model-base open-llama-3b-v2-q8_0.gguf \\
--checkpoint-in chk-lora-open-llama-3b-v2-q8_0-ultrachat-200k-LATEST.gguf \\
--checkpoint-out chk-lora-open-llama-3b-v2-q8_0-ultrachat-200k-ITERATION.gguf \\
--lora-out lora-open-llama-3b-v2-q8_0-ultrachat-200k-ITERATION.bin \\
--train-data "./dataset/train.txt" \\
--save-every 10 \\
--threads 6 --adam-iter 30 --batch 4 --ctx 64 \\
--use-checkpointing
In the llama.cpp repository, you can find all the [information](https://github.com/ggerganov/llama.cpp?tab=readme-ov-file#build) you need to build it for your architecture.
When the fine-tuning is finished, you can add the lora-adapters part to your Kitfile. Thanks to this, the lora-adapter fine-tuned will be packetized in your artifact.
manifestVersion: "1.0"
package:
name: llama3 fine-tuned
version: 3.0.0
authors: [Jozu AI]
code:
- description: Jupyter notebook with dataset creation
path: ./notebooks
model:
name: llama3-8B-instruct-q4_0
path: ghcr.io/jozu-ai/llama3:8B-instruct-q4_0
description: Llama 3 8B instruct model
license: Apache 2.0
parts:
- path: ./lora-open-llama-3b-v2-q8_0-ultrachat-200K-LATEST.bin
type: lora-adapter
datasets:
- description: training set from ultrachat_200k
name: training_set
path: ./data/train.txt
- description: test set from ultrachat_200k
name: test_set
path: ./data/test.txt
This new version of the kitfile can be pushed to your Git repository, and also the KitModel for the stage `tuned` can be packed and pushed. In your terminal, write:
kit pack /llama2_finetuning -t registry.gitlab.com/internal-llm/llama3-ultrachat-200k:tuned
kit push registry.gitlab.com/internal-llm/llama3-ultrachat-200k:tuned
You can run the fine-tune stage many times, changing training parameters or the fine-tuning strategy or both. For every run of fine-tuning, you can tag (i.e., with a version) a new ModelKit, in this way, you have all your fine-tuning attempts.
## Stage 3: Create the challenger
When the metrics that matter most for your use case, such as accuracy, precision, recall, F1 score, or mean absolute error, exceed the thresholds you set, your fine-tuned model is ready to challenge the champion model; the ModelKit can be tagged as the challenger. In your terminal, do this with:
kit pack /llama2_finetuning -t registry.gitlab.com/internal-llm/llama3-ultrachat-200k:challenger
kit push registry.gitlab.com/internal-llm/llama3-ultrachat-200k:challenger
Note that at this stage, the ModelKit contains the model, the datasets, and the code necessary for the fine-tuning. In this way, anyone can fully reproduce the fine-tuning stage, and so can the challenger.
Now, the challenger model can be deployed to production for A/B testing and is ready to challenge the champion model. If the challenger model performs better, it becomes the champion. You are now ready to deploy the new version of your model to production.
## Stage 4: Deploy the new champion
At this stage, you can retag the same challenger ModelKit, which contains the model (plus lora-adapters), the code, and the datasets, with a new tag: champion.
For the deployment to the production environment, for example, to Kubernetes through an init container, you can use an image with the kit CLI and unpack only the model to the shared volume of the pod:
kit unpack registry.gitlab.com/internal-llm/llama3-ultrachat-200k:champion --model -d /path/to/shared/volume
Now, the new champion is deployed to production, and every step of the MLOps pipeline, from the Jupyter Notebook to the deployment of the model in production, is completed.
Thanks to [KitOps](https://kitops.ml/) and ModelKit, the model's development, fine-tuning, and deployment process is fully reproducible. Each artifact created is immutable, shareable among team members, secure, and stored in your preferred container registry.

1,915,755 | [Article as Code] Syncing Articles Between Dev.to and Multiple Blogging Platforms | In the world of content creation, each platform offers unique advantages. Publishing articles on... | 0 | 2024-07-08T12:44:12 | https://dev.to/jacktt/article-as-code-syncing-articles-between-devto-and-multiple-blogging-platforms-4a7c | In the world of content creation, each platform offers unique advantages. Publishing articles on various platforms helps us expand our audience. However, managing and synchronizing your articles across multiple platforms can become a tedious task.
To address this need, I've developed an application called "Article as Code," which boasts several key features:
- Collects articles from your blog and stores them on GitHub as a "source of truth".
- Synchronizes all articles located in the repository to all your desired platforms.
- Allows you to write new articles by committing directly to this repository.
## Setup your own AAC
### Step 1: Create A New Github Repo
### Step 2: Create Github Action Secretes
```
Go to Repo > Setting > Secrets and Variables > Actions > New repository secrete
```
You will need to create the following secrets:
- `DEVTO_TOKEN`: Your Dev.to authentication token.
- `DEVTO_USERNAME`: Your Dev.to username.
- `HASHNODE_TOKEN`: Your Hashnode authentication token.
- `HASHNODE_USERNAME`: Your Hashnode username.
### Step 2: Schedule sync process
To automate the synchronization process, we'll set up a GitHub Action workflow. Create a new file named `.github/workflows/cronjob.yml` in your repository with the following contents:
```yml
name: "Cronjob"
on:
schedule:
- cron: '15 */6 * * *'
push:
branches:
- 'main'
jobs:
sync:
permissions: write-all
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v3
- uses: actions/setup-go@v4
with:
go-version: '1.21.0'
- name: Prepare
run: export PATH=$PATH:$(go env GOPATH)/bin
- name: Install
run: go install github.com/huantt/article-as-code@v1.0.3
- name: Collect
run: |
article-as-code collect \
--username=${{ secrets.DEVTO_USERNAME }} \
--article-folder=articles
- name: Sync to dev.to
run: |
article-as-code sync \
--username=${{ secrets.DEVTO_USERNAME }} \
--auth-token=${{ secrets.DEVTO_TOKEN }} \
--article-folder=articles \
--destination="dev.to"
- name: Sync to hashnode.dev
run: |
article-as-code sync \
--username=${{ secrets.DEVTO_USERNAME }} \
--auth-token=${{ secrets.HASHNODE_USERNAME }} \
--article-folder=articles \
--destination="hashnode.dev"
- name: Commit
run: |
git config user.name github-actions
git config user.email github-actions@github.com
git add .
if git diff --cached --exit-code; then
echo "No changes to commit."
exit 0
else
git commit -m "update"
git rebase main
git push origin main
fi
```
This GitHub Action will run every 6 hours or whenever you push a new commit to the main branch. Here's what it does:
1. Collect all your articles from dev.to then store into the `articles` folder.
2. Sync articles to dev.to
_(In this case, it's redundant, but it will cover the scenario when you write a new article by committing directly to this repository.)_
3. Sync articles to hashnode.dev

これからもPubNubをよろしくお願いします！
🛠️
---
### FCMペイロードのカスタムフィールド
**タイプ**改善
FCMモバイルプッシュ通知のペイロードに追加できるPubNubのカスタムパラメータ`pn_debug`、`pn_exceptions`、`pn_dry_runを`追加して、[Androidモバイルプッシュ通知の](https://pubnub.com/docs/general/push/android#step-5-construct-the-push-payload)ドキュメントを修正しました。
これらのパラメータを使用すると、通知をテストまたはデバッグしたり、通知を受信しないように選択したデバイスを除外したりできます。
以下は、カスタムフィールドを含むFCMペイロードのサンプルです：
```js
{
"pn_fcm": {
"notification": {
"title": "My Title",
"body": "Message sent at"
},
"pn_collapse_id": "collapse-id",
"pn_exceptions": [
"optional-excluded-device-token1"
]
},
"pn_debug": true,
"pn_dry_run": false
}
```
### チャネルグループの制限
**タイプ**新機能
管理ポータルのStream Controllerに、有料[プランの](https://www.pubnub.com/pricing/?utm_source=devto&utm_medium=syndication&utm_campaign=off_domain&utm_content=ja)お客様向けに[チャンネルグループ制限](https://pubnub.com/docs/general/metadata/basics#configuration)オプションが追加されました。デフォルトの上限である1,000チャンネルを下げることも、2,000チャンネルまで増やすこともできます。
### アプリコンテキストのユーザーメタデータイベント
**タイプ**改善
**User Metadata Events**オプションを有効にすると、ユーザー・エンティティの変更`（設定と` `削除`）がメンバーシップ関連にイベント通知を送信するため、そのユーザーとそのユーザーがメンバーであるチャネルの両方にイベント通知が送信されることを明確にするため、ドキュメントを改善しました。詳細は[ドキュメントを](https://pubnub.com/docs/general/metadata/basics#app-context-events)参照してください。
### アプリコンテキスト設定の依存関係
**タイプ**改善
[App Contextの設定オプションに関する](https://pubnub.com/docs/general/metadata/basics#configuration)ドキュメントを更新し、重要な依存関係についての情報を追加した。
**Disallow Get All Channel Metadata**」と「**Disallow Get All User Metadata**」オプションは一見わかりやすいように見えますが、これらのオプションはAccess Managerが有効な場合にのみ機能するという注意点があります。
言い換えると、Access Managerがない場合、これらのアクティブなオプションは、実際にはキーセットのユーザーまたはチャンネルに関するメタデータの取得を無効にしない。同時に、Access Managerを有効にすると、デフォルトでキーセット上のすべてのオブジェクトへのアクセスが制限されるため、細かい権限スキーマを作成しなくても、これらの設定オプションの両方のチェックを外すことで、ユーザーとチャンネルに対するAccess ManagerのGET制限を簡単に回避することができる。
Admin Portal UIにも、この依存関係がまもなく反映される予定です。
### App Contextの新しい参照整合性フラグ
**タイプ**新機能
管理ポータルのアプリのキーセットでApp Contextを有効にすると、デフォルトでオンになる新しい[**Enforce referential integrity for memberships**](https://pubnub.com/docs/general/metadata/basics#configuration)オプションを追加した。
このフラグにより、メンバーシップを作成したユーザIDとチャネルIDの両方が存在する場合にのみ、新しいメンバーシップを設定できるようになります。同時に、親ユーザまたはチャネルのメタデータ・エンティティを削除すると、その削除されたエンティティの子メンバーシップ関連付けが自動的に削除されます。こうすることで、キーセット上のメンバーシップ・オブジェクトに不具合や欠落が生じないようにすることができる。
SDK 📦 Pythonドキュメントの改善
----------------------
### Pythonドキュメントの改善
**タイプ**改善
頂いたフィードバックに従い、メソッドの使用法と実行に関する情報を拡張しました。その結果、[Python SDKドキュメントの](https://pubnub.com/docs/sdks/python/api-reference/publish-and-subscribe)各Returnsセクションでは、各メソッドが返すデータフィールドについて説明するようになりました。また、同期(`.sync()`)と非同期(`.pn_async(callback)`)リクエストの実行が、各メソッドの戻りデータにどのように影響するかも説明しています。
### React SDKは廃止されました。
**タイプ**非推奨のお知らせ
しばらくReact SDKの開発を積極的に行っていなかったため、最終的に正式に非推奨とし、[ドキュメント](https://pubnub.com/docs/sdks/react)内の[Call For Contributions](https://pubnub.com/docs/sdks#call-for-contributions)セクションに移動することにしました。
React SDKのバグを見つけたり、機能を拡張したい場合は、遠慮なく[リポジトリに](https://github.com/pubnub/react)プルリクエストを作成し、私たちのフィードバックをお待ちください！

### REST APIドキュメントのユーザー期間とデバイスメトリクス
**タイプ**改善
[先月](https://pubnub.com/docs/release-notes/2024/may#device-metrics-dashboard)、管理ポータルのPubNub Insightsの`User Behavior`ダッシュボードにデバイスメトリクスを導入しました。今月は、[REST APIドキュメントを](https://pubnub.com/docs/sdks/rest-api/introduction-16)更新し、ユーザー期間とデバイスメトリクスの両方を含めるようにしました。これにより、PubNub Insights APIを直接呼び出して、関心のあるメトリクスを取得できます。
BizOpsワークスペース 🏢 🏢 ←クリック
-------------------------
### トップ20ユーザー/チャンネル
**タイプ**新機能
App Contextを使用してユーザーとチャネルを保存および管理しない場合でも、テストデータをインポートすることで、関連するBizOps Workspace機能をテストできます。
PubNub Insightsにアクセスできる場合は、管理者ポータルのBizOps Workspaceの**User Management**モジュールと**Channel Management**モジュールにアクセスし、\[**Import from Insights**\]ボタンをクリックします。
その結果、アプリのキーセットから、直近1日以内に最も多くのメッセージを公開した最大20人のユーザーがインポートされます（昨日メッセージが送信されていない場合、ユーザーは前日のデータに基づいてインポートされます）。
ユーザーと同様に、アプリのキーセットから、直近1日以内に公開されたメッセージ数が最も多いチャンネルを最大20チャンネルまでインポートできます。
このテストデータを使用して、BizOps Workspaceが提供するものを探求してください。
### プレゼンス管理UXの刷新
**タイプ**改善
最近、BizOps Workspaceの[プレゼンス管理](https://pubnub.com/docs/bizops-workspace/presence-management)モジュール全体のデザインを変更し、ルール作成ウィザードを簡素化し、バッジの色をより包括的なものに変更し、キーセットのプレゼンス設定のデフォルトの「すべてのチャンネルでプレゼンスを有効にする」設定を反映する「キャッチオール」パターン設定を追加しました。
新しいルック＆フィールを気に入っていただければ幸いです！ | pubnubdevrel |
