React 19 Compatibility

[chris48s]

Docusaurus 3.7 is now compatible with React 19
https://docusaurus.io/blog/releases/3.7

Had a quick look at this.
I think for this lib there's a couple of blockers in the package tree before we can start looking at code changes:

1. @monaco-editor/react does not have a React 19 compatible stable release, although they have put out a pre-release. See Plans for React v19 Support suren-atoyan/monaco-react#656
2. @docusaurus/plugin-debug (which is a transitive dependency of @docusaurus/preset-classic ) needs a fix for react 19. There's a merged PR for this upgrading to a compatible version of react-json-view-lite chore(plugin-debug): upgrade react-json-view-lite to v2, prepare for React 19 facebook/docusaurus#10819 but it has not made its way into a published release on NPM yet.

@monaco-editor/react 4.7.0 is now out
still waiting on @docusaurus/preset-classic

seems like @docusaurus/plugin-debug had a release today, as this was merged in early jan i think the fix should be included already in the release.

Looks like the latest stable for that is still 3.7.0 from ~2 months ago

v3.8 of all the docusaurus plugins are out, so this should now be unblocked

We still seem to have an issue with @reduxjs/toolkit@1.9.7 (latest v1 release) see package.json that's a dependcy for for docusaurus-preset-openapi when i try to upgrade with npm.
This is as the demo work, maybe it has something to do with using yarn for the demo.

There is a newer v2 version for @reduxjs/toolkit with support for react 19.

Am i missing something or should i attempt at a PR to upgrade @reduxjs/toolkit?

Looks like I missed this in #298 😞
I think the difference is this project doesn't enforce strict peer deps, whereas on shields you do.

Having a really quick look at it, @reduxjs/toolkit 2.4 is react 18 only
https://github.com/reduxjs/redux-toolkit/blob/v2.4.0/package.json#L48-L49
and 2.5 onwards is react 19 only
https://github.com/reduxjs/redux-toolkit/blob/v2.5.0/package.json#L48-L49
so you could probably make the package requirement @reduxjs/toolkit@^2.4.0 and keep this package compatible with both versions. Then client apps can install 2.4 for react 18 and 2.5+ for v19, hopefully 🤞
You might need to account for breaking changes to jump to 2.x

I don't have time free to work on this, but if you are able to make a PR I will aim to review for you.
