Highlights 💡
EsmLibraryPlugin supports preserveModules
EsmLibraryPlugin now provides experimental support for the preserveModules feature. This allows you to maintain your source code structure as is while bundling all libraries within the node_modules folder. You can try it out using the following configuration example:
Feel free to copy and use it!
import { rspack } from "@rspack/core";
import path from 'node:path'
export default{
entry: "./index.js",
output: {
chunkFormat: false, // required, EsmLibraryPlugin handles how chunk renders
chunkLoading: 'import', // required, using es module dynamic import syntax to load other chunks
},
optimization: {
runtimeChunk: true, // recommended if you have async chunks
concatenateModules: false, // required, EsmLibraryPlugin handles scope hoisting
},
plugins: [
new rspack.experiments.EsmLibraryPlugin({
preserveModules: path.resolve(__dirname, './src')
})
],
};Experimental supports for defer import
Rspack now supports defer import, you can enable it by experiments.deferImport = true. It is worth noting that we currently only support import defer, import.defer() will be implemented in the near future.
export default {
experiments: {
deferImport: true
}
