#EsmLibraryPlugin

Rspack provides experimental EsmLibraryPlugin plugin, provides statically analyzable, cleaner output for ESM library, and also supports code splitting.

import { rspack } from '@rspack/core';

export default {
  plugins: [new rspack.experiments.EsmLibraryPlugin()],
  optimization: {
    runtimeChunk: true, // recommended to enable runtime chunk, otherwise consumers need to import runtime code from entry
  },
};

#Known limits

• Execution order of modules is not 100% guaranteed, so avoid relying on side effects of execution orders.
• Currently does not support context module and ModuleFederation, but this will be improved in the future.
