Class StateProvider

The Angular 1 StateProvider

The $stateProvider works similar to Angular's v1 router, but it focuses purely on state.

A state corresponds to a "place" in the application in terms of the overall UI and navigation. A state describes (via the controller / template / view properties) what the UI looks like and does at that place.

States often have things in common, and the primary way of factoring out these commonalities in this model is via the state hierarchy, i.e. parent/child states aka nested states.

The $stateProvider provides interfaces to declare these states for your app.

Methods

  • decorator(name: string, func: BuilderFunction): Function | function[] | this
  • Decorates states when they are registered

  • Decorates states when they are registered

    Allows you to extend (carefully) or override (at your own peril) the stateBuilder object used internally by StateRegistry. This can be used to add custom functionality to ui-router, for example inferring templateUrl based on the state name.

    When passing only a name, it returns the current (original or decorated) builder function that matches name.

    The builder functions that can be decorated are listed below. Though not all necessarily have a good use case for decoration, that is up to you to decide.

    In addition, users can attach custom decorators, which will generate new properties within the state's internal definition. There is currently no clear use-case for this beyond accessing internal states (i.e. $state.$current), however, expect this to become increasingly relevant as we introduce additional meta-programming features.

    Warning: Decorators should not be interdependent because the order of execution of the builder functions in non-deterministic. Builder functions should only be dependent on the state definition object and super function.

    Existing builder functions and current return values:

    • parent {object} - returns the parent state object.
    • data {object} - returns state data, including any inherited data that is not overridden by own values (if any). or null.
    • navigable {object} - returns closest ancestor state that has a URL (aka is navigable).
    • params {object} - returns an array of state params that are ensured to be a super-set of parent's params.
    • views {object} - returns a views object where each key is an absolute view (template, controller) for the view. Even when you don't use the views object explicitly on a state config, one is still created for you internally. So by decorating this builder function you have access to decorating template and controller properties.
    • ownParams {object} - returns an array of params that belong to the state, not including any params defined by ancestor states.
    • path {string} - returns the full path from the root down to this state. Needed for state activation.
    • includes {object} - returns an object that includes every state that would pass a $state.includes() test.

    Example:

    Override the internal 'views' builder with a function that takes the state definition, and a reference to the internal function being overridden:

    $stateProvider.decorator('views', function (state, parent) {
      let result = {},
          views = parent(state);
    
      angular.forEach(views, function (config, name) {
        let autoName = (state.name + '.' + name).replace('.', '/');
        config.templateUrl = config.templateUrl || '/partials/' + autoName + '.html';
        result[name] = config;
      });
      return result;
    });
    
    $stateProvider.state('home', {
      views: {
        'contact.list': { controller: 'ListController' },
        'contact.item': { controller: 'ItemController' }
      }
    });
    
    // Auto-populates list and item views with /partials/home/contact/list.html,
    // and /partials/home/contact/item.html, respectively.
    $state.go('home');
    

    builder function. The function receives two parameters:

    • {object} - state - The state config object.
    • {object} - super - The original builder function.
    • url {object} - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher} name (i.e. "viewName@stateName") and each value is the config object

    Parameters

    • name string
      :

      The name of the builder function to decorate.

    • func BuilderFunction
      :

      A function that is responsible for decorating the original

    Returns Function | function[] | this

    :

    $stateProvider - $stateProvider instance


  • onInvalid(callback: OnInvalidCallback): Function
  • Registers an invalid state handler

  • Registers a state

    This is a passthrough to StateRegistry.register.

    Registers a state configuration under a given state name. The stateConfig object has the following acceptable properties.

    • template - {string|function=} - html template as a string or a function that returns an html template as a string which should be used by the uiView directives. This property takes precedence over templateUrl.

      If template is a function, it will be called with the following parameters:

      • {array.<object>} - state parameters extracted from the current $location.path() by applying the current state

    • templateUrl - {string|function=} - path or function that returns a path to an html template that should be used by uiView.

      If templateUrl is a function, it will be called with the following parameters:

      • {array.<object>} - state parameters extracted from the current $location.path() by applying the current state

    • templateProvider - {function=} - Provider function that returns HTML content string.

    • controller - {string|function=} - Controller fn that should be associated with newly related scope or the name of a registered controller if passed as a string.

    • controllerProvider - {function=} - Injectable provider function that returns the actual controller or string.

    • controllerAs – {string=} – A controller alias name. If present the controller will be published to scope under the controllerAs name.

    • resolve - {object.<string, function>=} - An optional map of dependencies which should be injected into the controller. If any of these dependencies are promises, the router will wait for them all to be resolved or one to be rejected before the controller is instantiated. If all the promises are resolved successfully, the values of the resolved promises are injected and $stateChangeSuccess event is fired. If any of the promises are rejected the $stateChangeError event is fired. The map object is:

      • key - {string}: name of dependency to be injected into controller
      • factory - {string|function}: If string then it is alias for service. Otherwise if function, it is injected and return value it treated as dependency. If result is a promise, it is resolved before its value is injected into controller.

    • url - {string=} - A url with optional parameters. When a state is navigated or transitioned to, the $stateParams service will be populated with any parameters that were passed.

    • params - {object=} - An array of parameter names or regular expressions. Only use this within a state if you are not using url. Otherwise you can specify your parameters within the url. When a state is navigated or transitioned to, the $stateParams service will be populated with any parameters that were passed.

    • views - {object=} - Use the views property to set up multiple views or to target views manually/explicitly.

    • abstract - {boolean=} - An abstract state will never be directly activated, but can provide inherited properties to its common children states.

    • onEnter - {object=} - Callback function for when a state is entered. Good way to trigger an action or dispatch an event, such as opening a dialog. If minifying your scripts, make sure to use the ['injection1', 'injection2', function(injection1, injection2){}] syntax.

    • onExit - {object=} - Callback function for when a state is exited. Good way to trigger an action or dispatch an event, such as opening a dialog. If minifying your scripts, make sure to use the ['injection1', 'injection2', function(injection1, injection2){}] syntax.

    • reloadOnSearch = true - {boolean=} - If false, will not retrigger the same state just because a search/query parameter has changed (via $location.search() or $location.hash()). Useful for when you'd like to modify $location.search() without triggering a reload.

    • data - {object=} - Arbitrary data object, useful for custom configuration.

    Example:

    Some state name examples

    // stateName can be a single top-level name (must be unique).
    $stateProvider.state("home", {});
    
    // Or it can be a nested state name. This state is a child of the
    // above "home" state.
    $stateProvider.state("home.newest", {});
    
    // Nest states as deeply as needed.
    $stateProvider.state("home.newest.abc.xyz.inception", {});
    
    // state() returns $stateProvider, so you can chain state declarations.
    $stateProvider
      .state("home", {})
      .state("about", {})
      .state("contacts", {});
    

    To create a parent/child state use a dot, e.g. "about.sales", "home.newest".

    • name string
      :

      A unique state name, e.g. "home", "about", "contacts".

    • definition Ng1StateDeclaration
      :
