Platform detection service

As explained in Pro Angular 16

A platform detection service is an application service that exposes whether execution is occurring on a server or in a browser.

A platform detection service centralizes server-versus-browser checks for applications rendered with SSR. It wraps Angular’s platform APIs so application code can inspect execution context without repeatedly injecting PLATFORM_ID or calling isPlatformServer. section 27.4.2

Detecting server execution

Create PlatformService with an injected PLATFORM_ID value and an isServer getter. Register it with the application module, then use the getter when selecting environment-specific behavior such as a REST endpoint.

How Pro Angular 16 covers it

How deep it goes
Defines a small injectable wrapper and demonstrates endpoint selection, but does not elaborate broader browser-API adaptations.
Examples
Uses PlatformService, module registration, and server-versus-browser REST URL selection as implementation examples.
What it assumes
Assumes Angular services and SSR concepts while showing the required injection and module-registration steps.
What you can do after
Build it from scratch and apply it to guard browser-sensitive behavior and choose environment-specific application configuration.
How it connects
Connects SSR with Angular dependency injection, PLATFORM_ID, hydration, browser APIs, and environment-specific data access.
