AngularUI Router is a routing framework for [AngularJS](http://angularjs.org), which allows you to organize the
parts of your interface into a [*state machine*](https://en.wikipedia.org/wiki/Finite-state_machine). Unlike the
[`$route` service](http://docs.angularjs.org/api/ngRoute.$route) in the Angular ngRoute module, which is organized around URL
routes, UI-Router is organized around [*states*](https://github.com/angular-ui/ui-router/wiki),
which may optionally have routes, as well as other behavior, attached.
States are bound to *named*, *nested* and *parallel views*, allowing you to powerfully manage your application's interface.
Check out the sample app: http://angular-ui.github.io/ui-router/sample/
-
**Note:** *UI-Router is under active development. As such, while this library is well-tested, the API may change. Consider using it in production applications only if you're comfortable following a changelog and updating your usage accordingly.*
## Get Started
**(1)** Get UI-Router in one of the following ways:
- clone & [build](CONTRIBUTING.md#developing) this repository
- [download the release](http://angular-ui.github.io/ui-router/release/angular-ui-router.js) (or [minified](http://angular-ui.github.io/ui-router/release/angular-ui-router.min.js))
- via **[Bower](http://bower.io/)**: by running `$ bower install angular-ui-router` from your console
- or via **[npm](https://www.npmjs.org/)**: by running `$ npm install angular-ui-router` from your console
- or via **[Component](https://github.com/component/component)**: by running `$ component install angular-ui/ui-router` from your console
**(2)** Include `angular-ui-router.js` (or `angular-ui-router.min.js`) in your `index.html`, after including Angular itself (For Component users: ignore this step)
**(3)** Add `'ui.router'` to your main module's list of dependencies (For Component users: replace `'ui.router'` with `require('angular-ui-router')`)
When you're done, your setup should look similar to the following:
>
```html
<!doctype html>
<html ng-app="myApp">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.1.5/angular.min.js"></script>
<script src="js/angular-ui-router.min.js"></script>
<script>
var myApp = angular.module('myApp', ['ui.router']);
// For Component users, it should look like this:
// var myApp = angular.module('myApp', [require('angular-ui-router')]);
</script>
...
</head>
<body>
...
</body>
</html>
```
### [Nested States & Views](http://plnkr.co/edit/u18KQc?p=preview)
The majority of UI-Router's power is in its ability to nest states & views.
**(1)** First, follow the [setup](#get-started) instructions detailed above.
**(2)** Then, add a [`ui-view` directive](https://github.com/angular-ui/ui-router/wiki/Quick-Reference#ui-view) to the `<body />` of your app.
>
```html
<!-- index.html -->
<body>
<div ui-view></div>
<!-- We'll also add some navigation: -->
<a ui-sref="state1">State 1</a>
<a ui-sref="state2">State 2</a>
</body>
```
**(3)** You'll notice we also added some links with [`ui-sref` directives](https://github.com/angular-ui/ui-router/wiki/Quick-Reference#ui-sref). In addition to managing state transitions, this directive auto-generates the `href` attribute of the `<a />` element it's attached to, if the corresponding state has a URL. Next we'll add some templates. These will plug into the `ui-view` within `index.html`. Notice that they have their own `ui-view` as well! That is the key to nesting states and views.
>
```html
<!-- partials/state1.html -->
<h1>State 1</h1>
<hr/>
<a ui-sref="state1.list">Show List</a>
<div ui-view></div>
```
```html
<!-- partials/state2.html -->
<h1>State 2</h1>
<hr/>
<a ui-sref="state2.list">Show List</a>
<div ui-view></div>
```
**(4)** Next, we'll add some child templates. *These* will get plugged into the `ui-view` of their parent state templates.
>
```html
<!-- partials/state1.list.html -->
<h3>List of State 1 Items</h3>
<ul>
<li ng-repeat="item in items">{{ item }}</li>
</ul>
```
>
```html
<!-- partials/state2.list.html -->
<h3>List of State 2 Things</h3>
<ul>
<li ng-repeat="thing in things">{{ thing }}</li>
</ul>
```
**(5)** Finally, we'll wire it all up with `$stateProvider`. Set up your states in the module config, as in the following:
>
```javascript
myApp.config(function($stateProvider, $urlRouterProvider) {
//
// For any unmatched url, redirect to /state1
$urlRouterProvider.otherwise("/state1");
//
// Now set up the states
$stateProvider
.state('state1', {
url: "/state1",
templateUrl: "partials/state1.html"
})
.state('state1.list', {
url: "/list",
templateUrl: "partials/state1.list.html",
controller: function($scope) {
$scope.items = ["A", "List", "Of", "Items"];
}
})
.state('state2', {
url: "/state2",
templateUrl: "partials/state2.html"
})
.state('state2.list', {
url: "/list",
templateUrl: "partials/state2.list.html",
controller: function($scope) {
$scope.things = ["A", "Set", "Of", "Things"];
}
});
});
```

### [Multiple & Named Views](http://plnkr.co/edit/SDOcGS?p=preview)
Another great feature is the ability to have multiple `ui-view`s view per template.
**Pro Tip:** *While multiple parallel views are a powerful feature, you'll often be able to manage your
interfaces more effectively by nesting your views, and pairing those views with nested states.*
**(1)** Follow the [setup](#get-started) instructions detailed above.
**(2)** Add one or more `ui-view` to your app, give them names.
>
```html
<!-- index.html -->
<body>
<div ui-view="viewA"></div>
<div ui-view="viewB"></div>
<!-- Also a way to navigate -->
<a ui-sref="route1">Route 1</a>
<a ui-sref="route2">Route 2</a>
</body>
```
**(3)** Set up your states in the module config:
>
```javascript
myApp.config(function($stateProvider) {
$stateProvider
.state('index', {
url: "",
views: {
"viewA": { template: "index.viewA" },
"viewB": { template: "index.viewB" }
}
})
.state('route1', {
url: "/route1",
views: {
"viewA": { template: "route1.viewA" },
"viewB": { template: "route1.viewB" }
}
})
.state('route2', {
url: "/route2",
views: {
"viewA": { template: "route2.viewA" },
"viewB": { template: "route2.viewB" }
}
})
});
```
