svelte-preprocess-react

• Purpose: Enables seamless integration of React components within Svelte applications, acting as a bridge between the two frameworks. It supports features like nesting (slots/children), contexts, SSR, and hooks.

• Target Audience: Developers working with Svelte who need to:

  • Use third-party React components (temporarily).
  • Migrate an existing React codebase to Svelte (or vice versa).

• Key Features:

  • Svelte Support: Primary focus is Svelte, with a react. prefix syntax to embed React components directly in Svelte templates.
  • Type Safety: Optional sveltify() function for improved type-safety when wrapping React components.
  • Bidirectional Conversion: Includes reactify() to convert Svelte components back into React components for gradual migration.
  • Documentation: Covers advanced use cases like hooks, stores, routing migration (e.g., react-router → SvelteKit), and caveats.

• Warning: The library emphasizes that mixing frameworks is not ideal long-term due to performance overhead (bundle size, runtime speed) and developer experience trade-offs. It’s designed as a transitional tool, not a permanent solution.

• Example Workflow:

  <script>
    import YouTube from "react-youtube";
    const react = sveltify({ YouTube }); // Wrap React component
  </script>
  <react.YouTube videoId="AdNJ3fydeao" /> <!-- Use in Svelte template -->
  

• Migration Focus: Encourages replacing React dependencies with Svelte alternatives over time, with the goal of eventually removing the preprocessor entirely.
