Module Federation

Module Federation is a microfrontend pattern that involves 2 components:


  • Remote apps expose modules for other microfrontends apps to import.
  • Remote apps are compiled and deployed independently.
  • Remote apps expose an entry file that contains the exposed modules.


  • Host app consumes modules exposed from remote apps.
  • The host app owns a module registry that maps the module names with the remote location.
  • The remote modules are imported dynamically on-demand when requested.

Both Webpack and Vite support Module Federation.
