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 4 ways: - clone & [build](#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 ... ... ``` ### [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 `` of your app. > ```html
State 1 State 2 ``` **(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 `` 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

State 1

Show List
``` ```html

State 2

Show List
``` **(4)** Next, we'll add some child templates. *These* will get plugged into the `ui-view` of their parent state templates. > ```html

List of State 1 Items

``` > ```html

List of State 2 Things

``` **(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) { $scope.things = ["A", "Set", "Of", "Things"]; } }); }); ``` **(6)** See this quick start example in action. >**[Go to Quick Start Plunker for Nested States & Views](http://plnkr.co/edit/u18KQc?p=preview)** **(7)** This only scratches the surface >**[Dive Deeper!](https://github.com/angular-ui/ui-router/wiki)** ### [Multiple & Named Views](http://plnkr.co/edit/SDOcGS?p=preview) Another great feature is the ability to have multiple `ui-view`s view per template. **Pro Tip:** *While multiple parallel views are a powerful feature, you'll often be able to manage your interfaces more effectively by nesting your views, and pairing those views with nested states.* **(1)** Follow the [setup](#get-started) instructions detailed above. **(2)** Add one or more `ui-view` to your app, give them names. > ```html
Route 1 Route 2 ``` **(3)** Set up your states in the module config: > ```javascript myApp.config(function($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" } } }) }); ``` **(4)** See this quick start example in action. >**[Go to Quick Start Plunker for Multiple & Named Views](http://plnkr.co/edit/SDOcGS?p=preview)** ## Resources * [In-Depth Guide](https://github.com/angular-ui/ui-router/wiki) * [API Reference](http://angular-ui.github.io/ui-router/site) * [Sample App](http://angular-ui.github.com/ui-router/sample/) ([Source](https://github.com/angular-ui/ui-router/tree/gh-pages/sample)) * [FAQ](https://github.com/angular-ui/ui-router/wiki/Frequently-Asked-Questions) * [Slides comparing ngRoute to ui-router](http://slid.es/timkindberg/ui-router#/) * [UI-Router Extras / Addons](http://christopherthielen.github.io/ui-router-extras/#/home) (@christopherthielen) ### Videos * [Introduction Video](https://egghead.io/lessons/angularjs-introduction-ui-router) (egghead.io) * [Tim Kindberg on Angular UI-Router](https://www.youtube.com/watch?v=lBqiZSemrqg) * [Activating States](https://egghead.io/lessons/angularjs-ui-router-activating-states) (egghead.io) * [Learn Angular.js using UI-Router](http://youtu.be/QETUuZ27N0w) (LearnCode.academy) ## Report an Issue Help us make UI-Router better! If you think you might have found a bug, or some other weirdness, start by making sure it hasn't already been reported. You can [search through existing issues](https://github.com/angular-ui/ui-router/search?q=wat%3F&type=Issues) to see if someone's reported one similar to yours. If not, then [create a plunkr](http://plnkr.co/edit/u18KQc?p=preview) that demonstrates the problem (try to use as little code as possible: the more minimalist, the faster we can debug it). Next, [create a new issue](https://github.com/angular-ui/ui-router/issues/new) that briefly explains the problem, and provides a bit of background as to the circumstances that triggered it. Don't forget to include the link to that plunkr you created! **Note**: If you're unsure how a feature is used, or are encountering some unexpected behavior that you aren't sure is a bug, it's best to talk it out in the [Google Group](https://groups.google.com/forum/#!categories/angular-ui/router) or on [StackOverflow](http://stackoverflow.com/questions/ask?tags=angularjs,angular-ui-router) before reporting it. This keeps development streamlined, and helps us focus on building great software. Please keep in mind that the issue tracker is for *issues*. Please do *not* post an issue if you need help or support. Instead, see one of the above-mentioned forums or [IRC](irc://irc.freenode.net/#angularjs). ## Contribute **(1)** See the **[Developing](#developing)** section below, to get the development version of UI-Router up and running on your local machine. **(2)** Check out the [roadmap](https://github.com/angular-ui/ui-router/milestones) to see where the project is headed, and if your feature idea fits with where we're headed. **(3)** If you're not sure, [open an RFC](https://github.com/angular-ui/ui-router/issues/new?title=RFC:%20My%20idea) to get some feedback on your idea. **(4)** Finally, commit some code and open a pull request. Code & commits should abide by the following rules: - *Always* have test coverage for new features (or regression tests for bug fixes), and *never* break existing tests - Commits should represent one logical change each; if a feature goes through multiple iterations, squash your commits down to one - Make sure to follow the [Angular commit message format](https://github.com/angular/angular.js/blob/master/CONTRIBUTING.md#commit-message-format) so your change will appear in the changelog of the next release. - Changes should always respect the coding style of the project ## Developing UI-Router uses grunt >= 0.4.x. Make sure to upgrade your environment and read the [Migration Guide](http://gruntjs.com/upgrading-from-0.3-to-0.4). Dependencies for building from source and running tests: * [grunt-cli](https://github.com/gruntjs/grunt-cli) - run: `$ npm install -g grunt-cli` * Then, install the development dependencies by running `$ npm install` from the project directory There are a number of targets in the gruntfile that are used to generating different builds: * `grunt`: Perform a normal build, runs jshint and karma tests * `grunt build`: Perform a normal build * `grunt dist`: Perform a clean build and generate documentation * `grunt dev`: Run dev server (sample app) and watch for changes, builds and runs karma tests on changes.
