#lib.experiments

Used to enable some Rslib experimental features.

#experiments.advancedEsm

• Type: boolean
• Default: true

Controls whether to enable Rspack experimental ESM output. When enabled, it emits ESM output that is high-quality, more friendly to static analysis, and supports code splitting.

If you need to disable this feature, you can set it to false:

export default {
  lib: [
    {
      format: 'esm',
      bundle: true,
      experiments: {
        advancedEsm: false,
      },
    },
  ],
};
