Angular applications are built for a static deployment by default.
ng build in any shape or form, the build output is aggregated in the
dist folder and the resulting files can be statically served using any HTTP server that is capable of doing that (only a fallback for
index.html has to be configured).
When the application is served this way, the initial page response for the browser is minimal (
index.html with scripts inserted) and the application gets composed and rendered on the client side.
Of course, this can have a significant impact on the client side if no efficient rendering power is available.
This method of deployment is suitable for demo servers supplying a fast build chain.
However, we do not recommend this setup for production use.
This setup is also used for the Angular CLI built-in webpack-dev-server and should not be confused with a standard production setup.
To tackle sophisticated SEO requirements, the Angular Universal package was introduced.
In a second step in the build process, a server-side application can be built by the Angular CLI after building the client-side application.
The resulting distribution has to be executed in a node environment.
The server.js executable handles client requests on the server and pre-renders the content of the page, basically executing everything in a Node.js environment.
The resulting initial page response to the browser is mainly prepared and can be displayed quickly on the client side while the client-side application is booting up.
This method is the default setup for the Intershop PWA.
We provide a
Dockerfile for building the SSR Image.
If the Intershop PWA is run with an enabled Service Worker, the SSR process is only triggered for the first visit to the web page.
After that, the service worker lets the application behave like a simple browser-side application, where certain additional caching can lead to an improved client experience.
