Abstract

If you are reading this page, probably you already know that React-Redux 6.x performance aren't very good. IMHO, this is due to some technical errors:

1. use new React 16 Context to propagate Store value: React Context is very slow, and the common use is the propagation of values that rarely change like theme or language
2. use of <ReactReduxContext.Consumer> {value=>.... to read value of store : => render prop pattern, even if is a common and easy to use react pattern is slow

This fork use the new React Context only for propagate store instance, and do not use Context.Consumer render Prop.

These optimizations require to bump react version to 16.6 (but if you are using React 16.4 should be safe upgrade to 16.6)

In summary, react-redux-fork restore the performance of react-redux 5.x without Warnings for deprecated React lifycicles and legacy Context, (React 17 ready) and in some use cases is faster than old 5.x due React batched updates, that batched setState to do them in Top-Down mode.

Differences from React-Redux 6.0.0

• React version > 16.6 instead of 16.4
• Direct use of <ReactReduxContext.Consumer> { storeValue => ... is no more supported, too slow. use connect instead.
• using context prop on connected components is not recommended. Instead use connect(..., options.context:MyCustomContext) if you need custom context (rarely use-case, like libs). Read more about react-redux and context prop here: https://github.com/salvoravida/react-redux-fork/blob/master/context.md

Why not just a PR to official react-redux project?

Of Course i have done this before doing a fork, but rr manteiners do not seem to be opened to performances fixes :D

Luckily it's an open source project!

Note

Someones think that "you may do not need Redux", and that's true for small apps, but if you need it, you are probably working on a large enterprise app, so not only you need Redux, but you need it with the best possible performances! That's why i decide to fork this project.

redux-first-history

If you need performances, i would like to suggest you to have a look to this project https://github.com/salvoravida/redux-first-history In summary, replace "connected-react-router" with "redux-first-history" to get benefits from the best possible Redux approach:

• one way data-flow
• one unique source of truth

Let me know what do you think! Enjoy it? Star this project! :D
