    angular-ui-router-title

    Build Status

    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>
