purescript-react-basic-hooks VS redux-saga

First of all I had to choose what to use to manage the User Interface. I narrowed down to two modules: Halogen and react-basic-hooks (which is a “wrapper” of the unmaintained react-basic). I decided to go with react-basic-hooks just because I work with React on a daily basis and I wanted to understand its interoperability with PureScript. I will 10/10 try Halogen too in the next future since as far as I can see is the most famous and maintained in the PureScript community.

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.
