Module Federation with Server-Side Rendering

This guide will walk you through creating a Module Federated setup with Server Side Rendering (SSR) for Angular and React using Nx and its generators.

Steps

Section titled “Steps”

Create an empty workspace

Section titled “Create an empty workspace”

Run the following command with the options listed to create an empty workspace.

npx create-nx-workspace@latest myorg --preset=apps

Opting into Nx Cloud You will also be prompted whether to add Nx Cloud to your workspace. We won't address this in this recipe, but you can see the introduction to Nx Cloud for more details.

Install your framework plugin

Section titled “Install your framework plugin”
nx add @nx/angular

Generating a host and multiple remotes with SSR

Section titled “Generating a host and multiple remotes with SSR”

We will generate the apps required for a storefront application.
We will need the following applications:

  • Store - host application
  • Product - remote application
  • Checkout - remote application

Nx allows you to do this with a single command:

npx nx g @nx/angular:host apps/store --ssr --remotes=product,checkout

This will generate three applications, set up with SSR and Module Federation.

Serving the store application

Section titled “Serving the store application”

When using Module Federation, we want to serve the host application along with the remote applications so that everything works as expected.

To do this, run:

npx nx serve-ssr store

This will run all three application servers but only the store will be watching for file changes. If you make a change to one of the remote applications (checkout or product) the changes will not be hot reloaded.

Serving the store application with file watching for checkout

Section titled “Serving the store application with file watching for checkout”

If working on a remote application, we can still serve it via the host application and have it watch for changes.

To serve the store application and watch for changes on the checkout application run:

npx nx serve-ssr store --devRemotes=checkout
