The README mentions mobx-react but mobx-react is deprecated?

[kovkev]

Hi mobx experts!

I am trying to use mobx and I find that mobx-react (and mobx-react-lite) is deprecated: https://github.com/mobxjs/mobx-react . That repo has not been updated since Christmas 2020. It's odd because the mobx README mentions mobx-react in its example snippets.

How should I use mobx-react if it's deprecated? Can I get mobx-react by only doing npm install mobx and not doing npm install mobx-react ?

I think it's causing some issues like

Uncaught Error: [mobx] There are multiple, different versions of MobX active. Make sure MobX is loaded only once or use `configure({ isolateGlobalState: true })`

I tried

import { configure } from 'mobx';
configure( { isolateGlobalState: true });

but that didn't help.

Thank you,

kovkev

mobx-react and mobx-react-lite are not deprecated, they've been moved to this monorepo: https://github.com/mobxjs/mobx/tree/main/packages

It's written here: https://github.com/mobxjs/mobx-react#-this-repo-has-been-moved-to-mobx

So to use mobx with react you either do npm i mobx mobx-react-lite (only for functional components, my default choice) or npm i mobx mobx-react (if you have class components).

mobx-react already includes mobx-react-lite and adds class component support

I really wish that they had been named this:

mobx-react: What mobx-react-lite is
mobx-react-class: What mobx-react is

It has been one of the more confusing things I've encountered while evangelizing MobX. (Naming, unfortunately, isn't this team's strong suit.)

@jamonholmgren The issue is that mobx-react-class would mean not only classes but also functions. Because mobx-react = mobx-react-lite + classes. I believe it's no longer possible to change names due to BC break :) I explained to myself that '-light' is a lighter version of Mobx, without class support. Maybe it's helpful
