Plugin Feliz.HookAttribute expects v3.0 but currently running Fable v4.0.0-snake-island-alpha-009

[nojaf]

Hello Zaid! I was curious about Fable 4 and I was bumping all my tools/packages inside my sample project. Turns out I can't use [<ReactComponent>] with the latest alpha?

Is there any real restriction here? Or is the check of https://github.com/Zaid-Ajaj/Feliz/blob/295162276825b6e17cd8caac5d3f7ba8bc151ff8/Feliz.CompilerPlugins/ReactComponent.fs#L14 not taking alpha versions into account?

[nojaf]

Hmm, looks that way

https://github.com/fable-compiler/Fable/blob/dacbb6b51157ae01cbba3c835e0dd19e13b5dbdf/src/Fable.Transforms/Global/Compiler.fs#L79-L96

@alfonsogarciacaro any thoughts on this?

@nojaf Plugins are not compatible yet, because they depend on the internal AST and this has changed with the major version. Once the AST settles (probably soon) we'll update the plugins :)

BTW, there are currently no changes for JS (besides JSX support, but this still needs to be tuned up for React) so it's no necessary to update your JS projects yet. I'm still pushing Fable 3 releases with any JS-related fix 👍

[nojaf]

Hey, thanks for clarifying this. I'll stick to the stable bits.
