SolidJS

Thanks to the good compatibility of Rspack with the babel-loader, it is very easy to use SolidJS in rspack. All you need is babel-loader and solidjs babel preset. Rspack provides SolidJS example for reference.

rspack.config.js
/** @type {import('@rspack/cli').Configuration} */
const config = {
  context: __dirname,
  entry: {
    main: './src/index.jsx',
  },
  module: {
    rules: [
      {
        test: /\.jsx$/,
        use: [
          {
            loader: 'babel-loader',
            options: {
              presets: [['solid']],
              plugins: ['solid-refresh/babel'],
            },
          },
        ],
      },
    ],
  },
  builtins: {
    html: [
      {
        template: './index.html',
      },
    ],
  },
};
module.exports = config;
