STOP using Redux! Start using React Hooks UseContext instead 

I spent about a day refactoring my previous app by removing Redux completely. Curious if anybody did similar thing? and how match time it is actually taking for other cases?

I would have loved to see how this example looks in react too, so that I could decide which syntax looks better for me. A lot of reasons you mentioned against redux are subjective: "easy to misconfigure", "more difficult", "adds a lot of complexity to your code". For me the only valid argument you mentioned in the whole video is that useContext comes out of the box with react, while redux is a separate dependency. Also, I feel you are comparing apples to oranges, the true counterpart or replacement for redux would be the useReducer, which you don't mention in this video. Having to build the functionality of redux using useContext and useReducer feels like assembling low level stuff to something, which works out of the box with redux. Finally, there are other options to ease development with redux, as a starter I would recommend Eric Elliot's autodux, which does a good job in reducing the boilerplate code necessary for redux. Would have been nice to actually see your refactoring in a diff view to see how the 100s of lines of codes were reduced to 10s of lines of code.

I understand your point of view. But about the performance features and the side-effect management? If I have to implement everything, don't you think that it could be a "reinventing the wheel"?

Everything ok, BUT your component will always re-render when one of context' property change. Even if you want use only single prop. So if your app is small and store hasn't many props is good to use context but in more complicated apps better approach is to use mobx or redux. Am I wrong? :)

This is not alternative of Redux. In large applications it causes performance problems. We should only use contexts when we need to access data in many components, which are at different nesting levels. Furthermore, we need to make sure that we only use contexts for non-frequently changing data. Frequently changing values of contexts can cause our whole component tree to re-render, resulting in performance problems. That is why, for frequently changing values, we should use a state management solution such as Redux or MobX, instead.

Maybe your code is too simple.

i learn recrt this year, and prever context than redux

😂

How to use a Hook in a class Component... ? You don't know ? Exactly, because it's impossible. For everybody wondering... today, on May 2020, you can manage state with Hooks only in small application (or on a small component scale). But if you want to manage the user state with hooks.... soon or later, you will face some problems. Especially in the server-side rendering world where class component are absolutely necessary.
