R19 🏎️

A React 19 "framework" from scratch.

The name was definitely not inspired by F1 cars. :))

Features

This has a lot of cool caveats, like using Bun for most of the internals and (maybe) the first React 19 framework to implement ESM and not a bundler like Webpack to be bundled.

• Bundling
  • TS Support
    • JSX Support
  • Assets (Images, Styles, etc...)
• File-based routing
• RSC (React Server Components)
• RSA (React Server Actions)
• SSR
  • Static export
    • Serve static files for default route states

Examples

• Simple
  • A basic overview of the features
• Advanced
  • A more complex system with a SQLite database

Usage

This project uses react-server-dom-esm as the "plugin" to integrate with most of the React 19 features.

With all the dependencies set up, you can run the project with:

bun i && bun dev

License

I don't encourage anyone to use this project in production, not even close to it. This is just a fun project where all can learn more about React and its internals.
