When first you start using React JS, it feels like the greatest thing that has happened to you and it feels as if there is no other tool that can make your frontend development experience easier. And then your project gets bigger and more complex, which makes you want to abandon React because your states are super mess... | ['React', 'Front End Development', 'Software Development', 'State Management', 'Redux'] |
The Battle of state management
So, 2021 will be over in the next 6 months! What an amazing half year this was, wasn’t it?
Enough of this sarcasm. I think we all know the reality. I only turned this on because timing is really important for the topic this post will cover (as it might get change over time).

What is react?
React is a JS library used to build user interface.
2. Differentiate between functional and class components. What do you prefer to use and in which situation?
Functional component: A functional component is just a plain JavaScript function that accepts props as an argument and returns a React element... | ['React', 'Interview Questions', 'Frontend', 'React Concept', 'Redux'] |
Understanding Redux Workflow
If you worked with React in any capacity at all, it’s highly likely you’ve heard of a library called Redux. If you haven’t used it before you might be wondering what it is and how it might be helpful to you. Well lucky for you, this blog post is here to answer that. In addition, we’ll also... | ['JavaScript', 'React', 'State Management', 'Jsx', 'Redux'] |
In application development using a component-based library like ReactJS, every component is managing its own local state, and the root component usually manages the state for the whole application.
But the problem is as the complexity of the application increases, the component state becomes unstable and it leads to a... | ['Dev', 'React', 'Mobx', 'Redux'] |
I’ve always believed there must be a better way to do the same with React JS. Although I have been using Redux to handle data fetching in projects.
Why React Query?
In redux, each fetch operation requires the developer to create:
three actions (fetch request, succeeded, failed)
three reducers (fetch request, succee... | ['JavaScript', 'React', 'React Query', 'Axios React', 'Redux'] |
Flux architecture
A way to organize changes in global states of our application. Global states that are shared across multiple components.

Typescript 4.1 introduced an incredibly powerful feature called Template Literal Types . It allows developers to write better typing for strings, so typescript can check them to match certain template:

Redux-thunk 原始碼
短短14行到底做了什麼呢XD?
開始之前我們先看一下 redux 的 applyMiddleware 做了什麼，這樣回過頭來看redux-thunk的原始碼才更清楚。
Redux API: applyMiddleware() api
Each middleware receives Store 's dispatch and getState functions as named arguments, and returns a function. The last middleware in the chain will receive the real store’s dispatch m... | ['Redux Middleware', 'Redux', 'Redux Thunk'] |
Redux or Context API: Differences between the state managers.

First I’d recommend you have a basic knowledge of React or any other component based frontend framework. For the last few years, thanks to Dan Abramov, Redux has been the state management solution for “big” React ap... | ['React', 'State', 'Context Api', 'Front End Development', 'Redux'] |
4.Context Performance
The most important bit to understand about Context is that it will re-render all components that are descendants of the context provider, whether or not they consume the context when a state change happens. The only exception to this rule is when the context provider’s children do not change and ... | ['JavaScript', 'React', 'React Context', 'Programming', 'Redux'] |
There are plenty of SSR tutorials out there. This article goes over how you incrementally work on SSR — how you add it to an existing application. If you want a basic tutorial on how to code a hello world SSR app, I think Redux’s article does a good job.

My first app!
This is my first major attempt at creating a fully functional React/Redux application. It’s available to use (Beta version) at https://kids-star-chart.herokuapp.com/.
When creating this application I used a back-end language Ruby on Rails. The front-end of course has JS React/Redux. I implemented a full... | ['React', 'Redux'] |
