Improve this DocUsing the $location service

The $location service parses the URL in the browser address bar (based on window.location) and makes the URL available to your application. Changes to the URL in the address bar are reflected into the $location service and changes to $location are reflected into the browser address bar.

The $location service:

  • Exposes the current URL in the browser address bar, so you can Watch and observe the URL. Change the URL.
  • Maintains synchronization between itself and the browser's URL when the user Changes the address in the browser's address bar. Clicks the back or forward button in the browser (or clicks a History link). Clicks on a link in the page.
  • Represents the URL object as a set of methods (protocol, host, port, path, search, hash).

Comparing $location to window.location

window.location $location service
purpose allow read/write access to the current browser location same
API exposes "raw" object with properties that can be directly modified exposes jQuery-style getters and setters
integration with AngularJS application life-cycle none knows about all internal life-cycle phases, integrates with $watch, ...
seamless integration with HTML5 API no yes (with a fallback for legacy browsers)
aware of docroot/context from which the application is loaded no - window.location.pathname returns "/docroot/actual/path" yes - $location.path() returns "/actual/path"

When should I use $location?

Any time your application needs to react to a change in the current URL or if you want to change the current URL in the browser.

What does it not do?

It does not cause a full page reload when the browser URL is changed. To reload the page after changing the URL, use the lower-level API, $window.location.href.

General overview of the API

The $location service can behave differently, depending on the configuration that was provided to it when it was instantiated. The default configuration is suitable for many applications, for others customizing the configuration can enable new features.

Once the $location service is instantiated, you can interact with it via jQuery-style getter and setter methods that allow you to get or change the current URL in the browser.

$location service configuration

To configure the $location service, retrieve the $locationProvider and set the parameters as follows:

  • html5Mode(mode): {boolean|Object}
    false or {enabled: false} (default) - see Hashbang mode
    true or {enabled: true} - see HTML5 mode
    {..., requireBase: true/false} (only affects HTML5 mode) - see Relative links
    {..., rewriteLinks: true/false/'string'} (only affects HTML5 mode) - see HTML link rewriting
    Default:

    {
  enabled: false,
  requireBase: true,
  rewriteLinks: true
}

  • hashPrefix(prefix): {string}
    Prefix used for Hashbang URLs (used in Hashbang mode or in legacy browsers in HTML5 mode).
    Default: '!'

Example configuration

$locationProvider.html5Mode(true).hashPrefix('*');

Getter and setter methods

$location service provides getter methods for read-only parts of the URL (absUrl, protocol, host, port) and getter / setter methods for url, path, search, hash: 

// get the current path
$location.path();

// change the path
$location.path('/newValue')

All of the setter methods return the same $location object to allow chaining. For example, to change multiple segments in one go, chain setters like this: 

$location.path('/newValue').search({key: value});

Replace method

There is a special replace method which can be used to tell the $location service that the next time the $location service is synced with the browser, the last history record should be replaced instead of creating a new one. This is useful when you want to implement redirection, which would otherwise break the back button (navigating back would retrigger the redirection). To change the current URL without creating a new browser history record you can call: 

$location.path('/someNewPath');
$location.replace();
// or you can chain these as: $location.path('/someNewPath').replace();

Note that the setters don't update window.location immediately. Instead, the $location service is aware of the scope life-cycle and coalesces multiple $location mutations into one "commit" to the window.location object during the scope $digest phase. Since multiple changes to the $location's state will be pushed to the browser as a single change, it's enough to call the replace() method just once to make the entire "commit" a replace operation rather than an addition to the browser history. Once the browser is updated, the $location service resets the flag set by replace() method and future mutations will create new history records, unless replace() is called again.

Setters and character encoding

You can pass special characters to $location service and it will encode them according to rules specified in RFC 3986. When you access the methods:

  • All values that are passed to $location setter methods, path(), search(), hash(), are encoded.
  • Getters (calls to methods without parameters) return decoded values for the following methods path(), search(), hash().
  • When you call the absUrl() method, the returned value is a full url with its segments encoded.
  • When you call the url() method, the returned value is path, search and hash, in the form /path?search=a&b=c#hash. The segments are encoded as well.

Hashbang and HTML5 Modes

$location service has two configuration modes which control the format of the URL in the browser address bar: Hashbang mode (the default) and the HTML5 mode which is based on using the HTML5 History API. Applications use the same API in both modes and the $location service will work with appropriate URL segments and browser APIs to facilitate the browser URL change and history management.

Hashbang mode (default mode)

In this mode, $location uses Hashbang URLs in all browsers. AngularJS also does not intercept and rewrite links in this mode. I.e. links work as expected and also perform full page reloads when other parts of the url than the hash fragment was changed.

  });
});

HTML5 mode

In HTML5 mode, the $location service getters and setters interact with the browser URL address through the HTML5 history API. This allows for use of regular URL path and search segments, instead of their hashbang equivalents. If the HTML5 History API is not supported by a browser, the $location service will fall back to using the hashbang URLs automatically. This frees you from having to worry about whether the browser displaying your app supports the history API or not; the $location service transparently uses the best available option.

  • Opening a regular URL in a legacy browser -> redirects to a hashbang URL
  • Opening hashbang URL in a modern browser -> rewrites to a regular URL

Note that in this mode, AngularJS intercepts all links (subject to the "Html link rewriting" rules below) and updates the url in a way that never performs a full page reload. 

it('should show example', function() {
  module(function($locationProvider) {
    $locationProvider.html5Mode(true);
    $locationProvider.hashPrefix('!');
  });
  inject(function($location) {
    // in browser with HTML5 history support:
    // open http://example.com/#!/a -> rewrite to http://example.com/a
    // (replacing the http://example.com/#!/a history record)
    expect($location.path()).toBe('/a');

    $location.path('/foo');
    expect($location.absUrl()).toBe('http://example.com/foo');

    expect($location.search()).toEqual({});
    $location.search({a: 'b', c: true});
    expect($location.absUrl()).toBe('http://example.com/foo?a=b&c');

    $location.path('/new').search('x=y');
    expect($location.url()).toBe('/new?x=y');
    expect($location.absUrl()).toBe('http://example.com/new?x=y');
  });
});

it('should show example (when browser doesn\'t support HTML5 mode', function() {
  module(function($provide, $locationProvider) {
    $locationProvider.html5Mode(true);
    $locationProvider.hashPrefix('!');
    $provide.value('$sniffer', {history: false});
  });
  inject(initBrowser({ url: 'http://example.com/new?x=y', basePath: '/' }),
    function($location) {
    // in browser without html5 history support:
    // open http://example.com/new?x=y -> redirect to http://example.com/#!/new?x=y
    // (again replacing the http://example.com/new?x=y history item)
    expect($location.path()).toBe('/new');
    expect($location.search()).toEqual({x: 'y'});

    $location.path('/foo/bar');
    expect($location.path()).toBe('/foo/bar');
    expect($location.url()).toBe('/foo/bar?x=y');
    expect($location.absUrl()).toBe('http://example.com/#!/foo/bar?x=y');
  });
});

Fallback for legacy browsers

For browsers that support the HTML5 history API, $location uses the HTML5 history API to write path and search. If the history API is not supported by a browser, $location supplies a Hashbang URL. This frees you from having to worry about whether the browser viewing your app supports the history API or not; the $location service makes this transparent to you.

HTML link rewriting

When you use HTML5 history API mode, you will not need special hashbang links. All you have to do is specify regular URL links, such as: <a href="/some?foo=bar">link</a>

When a user clicks on this link,

  • In a legacy browser, the URL changes to /index.html#!/some?foo=bar
  • In a modern browser, the URL changes to /some?foo=bar

In cases like the following, links are not rewritten; instead, the browser will perform a full page reload to the original link.

  • Links that contain target element

Example: <a href="/ext/link?a=b" target="_self">link</a>

  • Absolute links that go to a different domain

Example: <a href="http://angularjs.org/%22>link</a>

  • Links starting with '/' that lead to a different base path

Example: <a href="/not-my-base/link">link</a>

If mode.rewriteLinks is set to false in the mode configuration object passed to $locationProvider.html5Mode(), the browser will perform a full page reload for every link. mode.rewriteLinks can also be set to a string, which will enable link rewriting only on anchor elements that have the given attribute.

For example, if mode.rewriteLinks is set to 'internal-link':

  • <a href="/some/path" internal-link>link</a> will be rewritten
  • <a href="/some/path">link</a> will perform a full page reload

Note that attribute name normalization does not apply here, so 'internalLink' will not match 'internal-link'.

Relative links

Be sure to check all relative links, images, scripts etc. AngularJS requires you to specify the url base in the head of your main html file (<base href="/my-base/index.html">) unless html5Mode.requireBase is set to false in the html5Mode definition object passed to $locationProvider.html5Mode(). With that, relative urls will always be resolved to this base url, even if the initial url of the document was different.

There is one exception: Links that only contain a hash fragment (e.g. <a href="#target">) will only change $location.hash() and not modify the url otherwise. This is useful for scrolling to anchors on the same page without needing to know on which page the user currently is.

Server side

Using this mode requires URL rewriting on server side, basically you have to rewrite all your links to entry point of your application (e.g. index.html). Requiring a <base> tag is also important for this case, as it allows AngularJS to differentiate between the part of the url that is the application base and the path that should be handled by the application.

Base href constraints

The $location service is not able to function properly if the current URL is outside the URL given as the base href. This can have subtle confusing consequences...

Consider a base href set as follows: <base href="/base/"> (i.e. the application exists in the "folder" called /base). The URL /base is actually outside the application (it refers to the base file found in the root / folder).

If you wish to be able to navigate to the application via a URL such as /base then you should ensure that your server is setup to redirect such requests to /base/.

See https://github.com/angular/angular.js/issues/14018 for more information.

Sending links among different browsers

Because of rewriting capability in HTML5 mode, your users will be able to open regular url links in legacy browsers and hashbang links in modern browser:

  • Modern browser will rewrite hashbang URLs to regular URLs.
  • Older browsers will redirect regular URLs to hashbang URLs.

Here you can see two $location instances that show the difference between Html5 mode and Html5 Fallback mode. Note that to simulate different levels of browser support, the $location instances are connected to a fakeBrowser service, which you don't have to set up in actual projects.

Note that when you type hashbang url into the first browser (or vice versa) it doesn't rewrite / redirect to regular / hashbang url, as this conversion happens only during parsing the initial URL = on page reload.

In these examples we use <base href="/base/index.html" />. The inputs represent the address bar of the browser.

Caveats

Page reload navigation

The $location service allows you to change only the URL; it does not allow you to reload the page. When you need to change the URL and reload the page or navigate to a different page, please use a lower level API, $window.location.href.

Using $location outside of the scope life-cycle

$location knows about AngularJS's scope life-cycle. When a URL changes in the browser it updates the $location and calls $apply so that all $watchers / $observers are notified. When you change the $location inside the $digest phase everything is ok; $location will propagate this change into browser and will notify all the $watchers / $observers. When you want to change the $location from outside AngularJS (for example, through a DOM Event or during testing) - you must call $apply to propagate the changes.

$location.path() and ! or / prefixes

A path should always begin with forward slash (/); the $location.path() setter will add the forward slash if it is missing.

Note that the ! prefix in the hashbang mode is not part of $location.path(); it is actually hashPrefix.

Crawling your app

Most modern search engines are able to crawl AJAX applications with dynamic content, provided all included resources are available to the crawler bots.

There also exists a special AJAX crawling scheme developed by Google that allows bots to crawl the static equivalent of a dynamically generated page, but this schema has been deprecated, and support for it may vary by search engine.

Testing with the $location service

When using $location service during testing, you are outside of the angular's scope life-cycle. This means it's your responsibility to call scope.$apply(). 

describe('serviceUnderTest', function() {
  beforeEach(module(function($provide) {
    $provide.factory('serviceUnderTest', function($location) {
      // whatever it does...
    });
  });

  it('should...', inject(function($location, $rootScope, serviceUnderTest) {
    $location.path('/new/path');
    $rootScope.$apply();

    // test whatever the service should do...

  }));
});

Two-way binding to $location

Because $location uses getters/setters, you can use ng-model-options="{ getterSetter: true }" to bind it to ngModel:
