Usage

To enable use of Webpack 5 with the angular cli you must use yarn as your package manager, it allows you to override the webpack dependencies for the CLI. The package.json contains the following section to override webpack to use version 5 instead of 4:

  "resolutions": {
    "webpack": "5.0.0"
  },

Project Structure

Shell

The shell project located in: projects/mdmf-shell folder, its contains the shell application which is used to load remote Microfrontends using dynamic routing constructed from the Microfrontend array. The list of Microfrontends can be loaded from a config if required, but for the example it is just an hardcoded array.

Profile Microfrontend

The profile project located in: projects/mdmf-profile contains a profile module with some child routes configured. The profile module is exposed as a remote module within the Module Federation config:

plugins: [
  new ModuleFederationPlugin({
    name: "profile",
    library: { type: "var", name: "profile" },
    filename: "remoteEntry.js",
    exposes: {
      ProfileModule:
        "./projects/mdmf-profile/src/app/profile/profile.module.ts",
    },
    shared: ["@angular/core", "@angular/common", "@angular/router"],
  }),
];
