Prepare for React 19

[memark]

This PR updates the code to eliminate some type problems with React 19 RC.

• Use React.JSX instead of global JSX.
• Use React.ReactNode instead of React.ReactChild

[JustFly1984]

Please, instead on prefixing React. everywhere, just import it on top of the file

import type { JSX } from 'react'

[memark]

Sure thing. Done!

@memark thank you for your PR. merged. Will try to find the time to release new version soon. I guess it need to bump peerDependencies too for react@19. please create one more PR. PS there is more than one package.

[JustFly1984]

PS2: I'm going to bring some love to this package soon, gonna replace gatsby.js with Vite, and maybe publish docs on Vite too. So no point to update gatsbyjs.

released 2.20.1

@memark if you want to help more, I have a branch upgrade, which I've used to release 2.20.0 and 2.20.1

We currently having issues with react-styleguidist, and it is refuses to start, I guess due to some esm/cjs inconsistencies.

I've spent yesteday to bring some love to the project, and half of today, but I have no time anymore. If you could fix styleguidist, or replace it with other docs, I would love to deploy it again. Else, I don't know then next time I will have time to bring more love to the project.

[memark]

I tried giving it a little love, but got no further. No combination of downgrading the styleguidist or docgen packages helped at all. Neither did removing our styleguide config. I haven't worked with Rollup/Webpack in years, so this will be difficult for me.

Do you have any idea when build:docs worked the last time?

[JustFly1984]

@memark It was broken since react@17 support added. It has been broken since.
I'm more inclined to use docosaurus at this point and get rid of styleguidist at all.
