Class Description
Location is a service that applications can use to interact with a browser's URL. Depending on which LocationStrategy is used, Location will either persist to the URL's path or the URL's hash segment.
Note: it's better to use Router service to trigger route changes. Use Location only if you need to interact with or create normalized URLs outside of routing.
Location is responsible for normalizing the URL against the application's base href. A normalized URL is absolute from the URL host, includes the application's base href, and has no trailing slash:
-
/my/app/user/123is normalized -
my/app/user/123is not normalized -
/my/app/user/123/is not normalized
Example
import {Component} from '@angular/core';
import {Location} from '@angular/common';
@Component({selector: 'app-component'})
class AppCmp {
constructor(location: Location) {
location.go('/foo');
}
}

Static Members
normalizeQueryParams(params: string) : string
Given a string of url parameters, prepend with '?' if needed, otherwise return parameters as is.
joinWithSlash(start: string, end: string) : string
Given 2 parts of a url, join them with a slash if needed.
stripTrailingSlash(url: string) : string
If url has a trailing slash, remove it, otherwise return url as is.
Class Details
path(includeHash?: boolean) : string
Returns the normalized URL path.
isCurrentPathEqualTo(path: string, query?: string) : boolean
Normalizes the given path and compares to the current normalized path.
normalize(url: string) : string
Given a string representing a URL, returns the normalized URL path without leading or trailing slashes.
prepareExternalUrl(url: string) : string
Given a string representing a URL, returns the platform-specific external URL path. If the given URL doesn't begin with a leading slash ('/'), this method adds one before normalizing. This method will also add a hash if HashLocationStrategy is used, or the APP_BASE_HREF if the PathLocationStrategy is in use.
go(path: string, query?: string) : void
Changes the browsers URL to the normalized version of the given URL, and pushes a new item onto the platform's history.
replaceState(path: string, query?: string) : void
Changes the browsers URL to the normalized version of the given URL, and replaces the top item on the platform's history stack.
forward() : void
Navigates forward in the platform's history.
back() : void
Navigates back in the platform's history.
subscribe(onNext: (value: any) => void, onThrow?: (exception: any) => void, onReturn?: () => void) : Object
Subscribe to the platform's popState events.
