@rspack/cli 0.3.4 on Node.js NPM

Highlight

Internal plugins

To further improve Rspack's compatibility with webpack ecosystem, we implemented internal plugins in Rspack.
For example, you can use rspack.XxxPlugin in your configuration.

const rspack = require('@rspack/core');

module.exports = {
  plugins: [
    new rspack.DefinePlugin({ 'process.env.NODE_ENV': "'production'", }),
    // In addition to webpack's existing plugins, some of the plugins implemented
    // in rust in Rspack are also exported by internal plugins
    new rspack.HtmlRspackPlugin({ template: './index.html' }),
  ],
};

Or use compiler.webpack.XxxPlugin in your plugin.

class ReactRefreshRspackPlugin {
  apply(compiler) {
    const reactRefreshPath = require.resolve("../client/reactRefresh.js");
    const reactRefreshEntryPath = require.resolve("../client/reactRefreshEntry.js");
    new compiler.webpack.EntryPlugin(compiler.context, reactRefreshEntryPath, {
      name: undefined
    }).apply(compiler);
    new compiler.webpack.ProvidePlugin({
      $ReactRefreshRuntime$: reactRefreshPath
    }).apply(compiler);
  }
};

@rspack/plugin-react-refresh

Thanks to the implementation of internal plugins, we can now easily implement the @rspack/plugin-react-refresh, which was coupled into @rspack/dev-server before.
Now, if you are using a custom dev server instead of @rspack/dev-server or @rspack/cli, you can easily enable react fast refresh by adding the @rspack/plugin-react-refresh plugin.

Compatible with html-webpack-plugin

Rspack is now html-webpack-plugin compatible!

const path = require("node:path")
const HtmlWebpackPlugin = require("html-webpack-plugin")

module.exports = {
  plugins: [
    new HtmlWebpackPlugin({
      template: "pug-loader!" + path.join(__dirname, "template.pug")
    })
  ]
}

`builtin:swc-loader` supports builtin transformations

These fields served as the alternative to the current builtin transform options, aiming to support transforming with respect to the certain module.

type RspackExperiments = {
  react?: ReactOptions;
  import?: PluginImportOptions;
  emotion?: EmotionOptions;
  relay?: RelayOptions;
};

For example, integrating emotion transformation in the project:

module.exports = {
  module: {
    rules: [
      {
         test: /\.jsx$/,
         exclude: /node_modules/,
         loader: "builtin:swc-loader",
         options: {
            jsc: {
              parser: {
                syntax: "ecmascript",
                jsx: true,
              }
            },
            rspackExperiments: {
              emotion: true
            }
         }
      }
    ]
  }
}
