react-redux VS redux-saga

React Redux (https://react-redux.js.org/)

You add the current user state to a React Context or state management library, read from it on the top bar, and write to it after a user signs in. Done. No big deal, right?

- Throws better errors in an RSC environment

- https://github.com/reduxjs/react-redux/releases/tag/v9.0.0

## Reselect 5.0:

- Switches to a new `weakMapMemoize` memoizer as default

- Renames `defaultMemoize` to `lruMemoize`

- Allows passing memoizer options direct to `createSelector`

- Many TS improvements

- https://github.com/reduxjs/reselect/releases/tag/v5.0.1

## Redux Thunk 3.0:

- Drops the default export and switches to named exports ( `{thunk, withExtraArgument}` )

- https://github.com/reduxjs/redux-thunk/releases/tag/v3.1.0

This has been a _huge_ year-long development effort!

We're thrilled to get these improvements out. The tooling and bundle improvements will help all users, and we think the features and TS changes will improve the Redux dev experience significantly.

Thank you SO MUCH to everyone who has contributed or helped test out the work!

Please file bug reports for the inevitable issues that pop up post-release!

but now I'm going off on a conf trip and going to take a very well-earned break from Redux work for December :)

react-redux : Integration with React

When your application needs a single source of truth. You'll be better off using a more powerful library like Redux

You should think about using some client state management libraries like Redux. Redux gives you the possibility to encapsulate states and manipulate it through functions. https://react-redux.js.org/

For the backend, we chose Python, Django Rest Framework. On the frontend, React, Redux, Saga, Sass. Let’s start with the backend, which was managed by Yegor. He writes about the server part of the project himself.

The whole article properly the best explanation of generators I have come across. This quote stuck out:

> Generators are a special type of function that can return multiple pieces of data during its execution. Traditional functions can return multiple data by using structures like Arrays and Objects, but Generators return data whenever the caller asks for it, and they pause execution until they are asked to continue to generate and return more data.

Applications of generators? I have only used Redux-Saga[1]. Can't even think of other libraries that use them, but would be interested in learning.

redux-saga. The most popular effects library in js

Redux can be extended with a lot of other packages. For example with a side effect manager, you can separate side effects from your business logic, help with error handling and in the same process make testing of side effects a lot easier.

Consumer vs. Producer: Check out Redux Saga

Your app will likely have to deal with async calls like making remote API requests. redux-thunk and redux-saga were created to solve those problems. They may take some time to understand as they require understanding of functional programming and generators. Our advice is to deal with it only when you need it.

Hey thanks for the thoughtful response.

I agree with everything you mentioned here. I'd love to continue to chat with you about how to make testing sagas better.

If you'd like, it would be great if we could move this convo to https://github.com/redux-saga/redux-saga/discussions/2337

If there are dependent API calls, you can probably look at redux-saga. It’s one of the best libraries out there to manage the data.

redux-saga makes use of them in really nice way. https://redux-saga.js.org/ That’s where I’ve used them the most.
