LocationStrategy

Enables the Location service to read route state from the browser's URL. Angular provides two strategies: HashLocationStrategy and PathLocationStrategy.

abstract class LocationStrategy {
  abstract path(includeHash?: boolean): string
  abstract prepareExternalUrl(internal: string): string
  abstract pushState(state: any, title: string, url: string, queryParams: string): void
  abstract replaceState(state: any, title: string, url: string, queryParams: string): void
  abstract forward(): void
  abstract back(): void
  abstract onPopState(fn: LocationChangeListener): void
  abstract getBaseHref(): string
}

Description

Applications should use the Router or Location services to interact with application route state.

For instance, HashLocationStrategy produces URLs like http://example.com#/foo, and PathLocationStrategy produces http://example.com/foo as an equivalent URL.

See these two classes for more.
