An app shell lets Universal render a portion of your application via a route at build time. This gives users a meaningful first paint of your application that appears quickly because the browser can simply render the HTML without the need to initialize any JavaScript.

Use this command with a routing app that is accompanied by a Universal server-side app.

To create an app shell, use the following command.

ng generate app-shell --client-project my-app --universal-project server-app

• my-app is the name of your client application
• server-app is the name of the Universal (server) application

The command adds two new architect build targets to your angular.json configuration file (along with a few other changes).

"server": { "builder": "@angular-devkit/build-angular:server", "options": {

"outputPath": "dist/my-app-server",
"main": "src/main.server.ts",
"tsConfig": "src/tsconfig.server.json"

} }, "app-shell": { "builder": "@angular-devkit/build-angular:app-shell", "options": {

"browserTarget": "my-app:build",
"serverTarget": "my-app:server",
"route": "shell"

} }

To verify the that the app has been built with the default shell content:

1. Run the app-shell target.

   ng run my-app:app-shell
</code-example>

1. Open dist/app-shell/index.html in your browser.

The default text "app-shell works!" verifies that the app-shell route was rendered as part of the output.
