Goact is a GDScript derivative of Roblox's Roact, which itself is a derivative of Facebook's React library. This framework allows for a compositional, state based approach to game development that's useful for designing complex applications, traditionally well suited for UI/frontend development.

This is nowhere near complete, mostly just a minimum viable product that still needs some work to get it adapted to the Godot ecosystem. Plus there are a lot of react/roact features that are still missing (like portals, fragments, hooks, etc.)

See:

• Roact - https://github.com/Roblox/roact
• React - https://github.com/facebook/react

• Copy the "goact" folder in "addons" into your project
• Close and reopen if your editor is already open
• Go to your project settings -> plugins and enable Goact
• Might need to restart again, Godot plugins seemed a bit finicky for me.

• In this repo there's a project that uses some components I made as examples of what Goact looks like.
• It essentially is a button that toggles an FPS counter, and some UX things like a selection indicator that tweens in/out when you hover on the button.
