Context + Hooks or Redux

Question

Actually I'm setting up a new project, got confused about choosing a flow:

useState + useReducer + useContext

or

Redux

The project is advanced and medium sized, it may leads to large app in near future or may not be.

If I go with option 1 (useState + useReducer + useContext) :

a. There is no middleware for useReducer (yet). Since it's not one global state container, it's difficult to apply such middleware globally. b. There is no native feature (yet) which combines all reducers to one ultimate reducer.

If I go with option 2, I can use the features which option 1 fails to provide.

I came across, that we can implement we can combine multiple reducers manually in option 1:

import userReducer from './reducers/user';
import basketReducer from './reducers/basket';
const mainReducer = ({ user, basket }, action) => ({
     user: userReducer(user, action),
     basket: basketReducer(basket, action)
});

and can implement middleware too

import userReducer from './reducers/user';
import basketReducer from './reducers/basket';
const mainReducer = ({ user, basket }, action) => {
  // middleware goes here, i.e calling analytics service, etc.
  return {
    user: userReducer(user, action),
    basket: basketReducer(basket, action)
  };
});

Actually I am freezing here to choose which way is optimal to go with ?

If I'm go with Redux, I have to implement Redux, axios, saga, immutable js or other third part libs. I'll be using powerful features of Redux and also I should learn all the concepts first for Redux. Since I know Context + hooks.

Is react officials have any plans to bring those missed ingredients from Redux to hooks + context ?

As usually it depends on many factors ) – Kasabucki Alexandr Sep 25 '19 at 07:30 — Kasabucki Alexandr, Sep 25 '19 at 07:30

Optimally, I would say they are both the same. They both support memoization. However, the advantage of Redux is it has a single source of truth for your entire application state.

Redux, Hooks, Context, Saga have different purposes / motivations.

Eventually, I suggest for you to use hooks + function components for the following reasons:

Eliminate wrapper hell due to context providers.
Handle side-effects (fetch, subscription) granularly via useEffect within functional components.

No, it contradicts its Design-Principles, the fact that you can implement those features by yourself (not very complicated), there are many stable and great state-managers in react's eco-system (like redux and mobx).

Common Abstraction (Design Principles): In general we resist adding features that can be implemented in userland. We don’t want to bloat your apps with useless library code. However, there are exceptions to this.

This question is too broad, it depends on your application logic, it scales and if you really need all redux features.

Refer to SO question React Context vs React Redux, when should I use each one?

If I'm go with Redux, I have to implement Redux, axios, saga, immutable js or other third party libs.

Using axios (fetch) and immutable (freeze) are not bound to redux, it is also recommended to not mutate data and use immutable libraries in your application.

Moreover, you don't have to integrate saga with your redux, after getting familiar with middleware, as mentioned above, depending on your application logic you may not need saga at all.
