Description

PlatformLocation encapsulates all calls to DOM APIs, which allows the Router to be platform-agnostic. This means that we can have different implementation of PlatformLocation for the different platforms that Angular supports. For example, @angular/platform-browser provides an implementation specific to the browser environment, while @angular/platform-server provides one suitable for use with server-side rendering.

The PlatformLocation class is used directly by all implementations of LocationStrategy when they need to interact with the DOM APIs like pushState, popState, etc.

LocationStrategy

in turn is used by the Location service which is used directly by the Router in order to navigate between routes. Since all interactions between Router / Location / LocationStrategy and DOM APIs flow through the PlatformLocation class, they are all platform-agnostic.
