rollup-plugin-react2svelte

Use parts or whole react projects in svelte.

Requirements

In the following I assume, that you use vite to set up your projects. Pure rollup projects might work as well, but I did not test, yet.

Installation

Install the plugin and a necessary dependency to react-svelte-interop:

npm i -D rollup-plugin-react2svelte react-svelte-interop

then update your vite.config.ts in root folder like this:

import { defineConfig } from 'vite'

import {svelte} from '@sveltejs/vite-plugin-svelte'
import react2svelte from 'rollup-plugin-react2svelte';

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [svelte(),react2svelte()],
  resolve:{
    alias:{
      "react":"react-svelte-interop",
      'react-dom/client':"react-svelte-interop/dom",
      'react-dom':"react-svelte-interop/dom"
    }
  }
})

If you use sveltekit, keep the sveltekit plugin instead of the svelte plugin.
