#treeShakingSharedPlugins

Allows users to explicitly specify which plugins should participate in the second tree-shaking pass for shared modules.

• Type: string[]
• Required: No
• Default: undefined

If shared.treeShaking.mode is set to 'server-calc', the deployment service will rebuild the shared dependencies that need tree shaking. In this process, only the shared dependencies are built, and the original project's build configuration is not loaded.

If your project relies on special build configuration—for example, setting externals—you can package that configuration into an NPM package, then provide the plugin name and version in treeShakingSharedPlugins. This allows the plugin to participate in the second tree-shaking pass for shared modules.

For example, suppose you provide a plugin my-build-plugin that sets externals:

class MyBuildPlugin {
  apply(compiler){
    compiler.options.externals = {
      'react': 'React',
    }
  }
}
export default MyBuildPlugin;

If you publish this plugin as version 0.0.2, you only need to specify its name and version in treeShakingSharedPlugins:

export default {
  // ...
  treeShakingSharedPlugins: ['my-build-plugin@0.0.2'],
}
