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 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 just a host application in your workspace, run the following command:
~/workspace❯
nx g @nx/react:host shell --directory=apps/react/shell
1> NX Generating @nx/react:host

3CREATE apps/react/shell/src/app/app.spec.tsx
4CREATE apps/react/shell/src/assets/.gitkeep
5CREATE apps/react/shell/src/environments/environment.prod.ts
6CREATE apps/react/shell/src/environments/environment.ts

Scaffold a Host with Remotes
To scaffold a host application along with remote applications in your workspace, run the following command:
~/workspace❯
nx g @nx/react:host shell-with-remotes --directory=apps/react/with-remotes/shell --remotes=remote1,remote2
1> NX Generating @nx/react:host

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:
❯
nx serve shell
Building your Host
In the same vein, you can build your host by running:
❯
nx build shell
