Experiments

experiments

boolean: false

experiments option was introduced in webpack 5 in order to empower users with an ability of activating and trying out experimental features.

Because experimental features have relaxed semantic versioning and might contain breaking changes, make sure to fix webpack's version to minor e.g. webpack: ~5.4.3 instead of webpack: ^5.4.3 or use a lockfile when using experiments.

Available options:

• mjs: Support .mjs files as a way to define EcmaScript modules
• outputModule: enables the use of output.module configuration option and sets it to true. Enables the use of output.libraryTarget as 'module' and sets it to 'module'.

webpack.config.js

module.exports = {
  //...
  experiments: {
    mjs: true
  }
};
