Luigi is a micro front-end JavaScript framework that enables the creation of an administrative user interface which is driven by local and distributed views. Luigi enables the communication between a web application and content-views which the application contains such as routing, navigation, authorization, and user experience elements.

Luigi consists of two components: Luigi core and Luigi client.

Luigi core is installed in the web application while Luigi client is installed in the application(s) running in the content-view. Both of these components interact with one another to leverage communication between both the web application and the content-view, without compromising the security principles behind the iframe pattern.


Luigi core

Luigi core is the part of Luigi that enables navigation, security and routing. To get started with Luigi, read this document.

Luigi client

Luigi client enables integration of Luigi in views. You can easily configure the lifecycle and links of the client, as well as customize the appearance of your navigation.

  • Lifecycle gives you details on the life cycle of listeners, navigation nodes and event data.
  • Link Manager allows you to navigate to a specific route.
  • UX Manager helps you to manage the appearance in Luigi.

See this document to learn more about the Luigi client.

Code formatting for contributors

All projects in the repository use Prettier to format source code. Run the npm install command in the root folder to install it along with husky, the Git hooks manager. Both tools ensure proper codebase formatting before committing it.


To ensure that existing features still work as expected after your changes, run UI tests from the Angular example application. Before running the tests, start the sample application by using the npm start command in the application folder.

When the application is ready:

  • Run npm run e2e:run in the core/examples/luigi-sample-angular folder to start tests in the headless browser.
  • Run npm run e2e:open in the core/examples/luigi-sample-angular folder to start tests in the interactive mode.
