angular-ui-router-title

AngularJS module for updating browser title/history based on the current ui-router state.

Motivation

Using ui-router states with url configurations enables browser history support and bookmarking of application state. It is important that the title in the browser history/bookmark represent the application state so that the user can tell where she's navigating to.

The module provides a $title variable on the $rootScope that is populated based on the $title value resolved in $state.$current (or one of its parent states). If the current state doesn't resolve a $title, then $rootScope.$title will be undefined.

The module also provides a $breadcrumbs array that is populated based on the $title of $state.$current and its parent states.

The module sets the document.title to the value of the $title variable or, if configured, to the value returned by a documentTitle(title) callback. The browser sets bookmark and browser history text based on the document.title.

Installing the Module

Installation can be done through bower:

bower install angular-ui-router-title

In your page add:

  <script src="bower_components/angular-ui-router-title/angular-ui-router-title.js"></script>

Loading the Module

This module declares itself as ui.router.title, so it can be declared as a dependency of your application as normal:

var app = angular.module('myApp', ['ng', 'ui.router.title']);

Specifying the $title in the state definition

A state defines its title by declaring a $title value in its resolve block. It's a good idea for the $title to include information from the current state, so it may need to inject the $stateParam or another value that was resolved from them.

$stateProvider
  .state('home', {
    ...
    resolve: {
      // Constant title
      $title: function() { return 'Home'; }
    }
  })
  .state('about', {
    url: '/about',
    ...
    resolve: {
      // Constant title
      $title: function() { return 'About'; }
    }
  })
  .state('contacts', {
    url: '/contacts',
    ...
    resolve: {
      // List of contacts
      contacts: ['Contacts', function(Contacts) {
        // Use Contacts service to retrieve list
        return Contacts.query();
      }],
      // Dynamic title showing number of contacts
      $title: ['contacts', function(contacts) {
        return 'Contacts (' + contacts.length + ')';
      }]
    }
  })
  .state('contact', {
    url: '/contact/:contactId',
    ...
    resolve: {
      // Single contact
      contact: ['Contacts', '$stateParams', function(Contacts, $stateParams) {
        // Use Contacts service to retrieve a contact
        return Contacts.get({ id: $stateParams.contactId });
      }],
      // Dynamic title showing the name of contact
      $title: ['contact', function(contact) {
        return contact.name;
      }]
    }
  })
  .state('contact.edit', {
    url: '/edit',
    ...
    resolve: {
      // Dynamic title appending to parent state's title
      $title: ['$title', function($title) {
        return $title + " (edit)";
      }]
    }
  })

Configuring a custom document.title

By default, the module will set the document.title to the value of $rootScope.$title. A common convention is to include the application name in the document.title. Customization of the document.title can be achieved via the $titleProvier.documentTitle callback specification.

angular.module('myApp', ['ng', 'ui.router.title'])
  .config(function($titleProvider) {
    $titleProvider.documentTitle(function($rootScope) {
      return $rootScope.$title ? $rootScope.$title + " - My Application" : "My Application";
    });
  });

Using the $title in a header

The $title property contains the resolve title and cen be used, for example, to set the contents of an <h1> tag.

  <h1 ng-bind="($title || 'Home') + ' - My Application'">My Application</h1>

Using the $breadcrumbs

The $breadcrumbs array contains objects, one for each state that resolves a $title value. Each entry contains:

• title: $title value of this state
• state: name of the state
• stateParams: $stateParams of the state.

<ol class="breadcrumb">
	<li ng-repeat="crumb in $breadcrumbs" ng-class="{ 'active' : $last }">
		<a ng-if="!$last" href="{{$state.href(crumb.state, crumb.stateParams)}}">{{crumb.title}}</a>
		<span ng-if="$last">{{crumb.title}}</span>
	</li>
</ol>
