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:
`` shell
bower install angular-ui-router-title
`

In your page add:
`html

`


Loading the Module
------------------

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

`javascript
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.

`javascript
$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.

`javascript
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

tag.

`html


My Application


`

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.

`html


1. 
   {{crumb.title}}
   {{crumb.title}}
