Creating a Host

A host is the term within Module Federation given to an application that loads and consumes federated modules from remotes. At build time, these modules do not exist and are instead fetched via a network request and executed at runtime. It can be likened to a modern-day approach to iframes.
A host can be configured to know the location of the federated modules at build time (called Static Federation) or it can employ a mechanism to discover the location of the federated modules at runtime, usually on startup (called Dynamic Federation).

Nx includes first-class support for helping you to scaffold a Module Federation Architecture for your React and Angular application(s).

Generating a Host

To generate only a host application in your workspace, run the following command:

Scaffold a Host with Remotes

To scaffold a host application along with remote applications in your workspace, run the following command:

Serving your Host

Your host application acts like any other application in the context of Nx, and therefore serving it locally is as simple as running:

When you serve your host, Nx will discover any dependent remote applications that are also in the workspace and serve them statically. To learn more about check out our in-depth breakdown of what happens when you serve your host.

Building your Host

In the same vein, you can build your host by running:

To support Independent Deployability host applications do not have implicitDependencies set in their project.json. If you want to build all your remotes when you build your host, add implicitDependencies to your host's project.json with each remote listed:
