  1. $route
  2. provider in module ngRoute

Overview

Used for configuring routes.

See $route for an example of configuring and using ngRoute.

Dependencies

Requires the ngRoute module to be installed.

Methods

  • when(path, route);

    Adds a new route definition to the $route service.

    Parameters

    Param Type Details
    path string

    Route path (matched against $location.path). If $location.path contains redundant trailing slash or is missing one, the route will still match and the $location.path will be updated to add or drop the trailing slash to exactly match the route definition.

    • path can contain named groups starting with a colon: e.g. :name. All characters up to the next slash are matched and stored in $routeParams under the given name when the route matches.
    • path can contain named groups starting with a colon and ending with a star: e.g.:name*. All characters are eagerly stored in $routeParams under the given name when the route matches.
    • path can contain optional named groups with a question mark: e.g.:name?.

      For example, routes like /color/:color/largecode/:largecode*\/edit will match /color/brown/largecode/code/with/slashes/edit and extract:

    • color: brown

    • largecode: code/with/slashes.
    route Object

    Mapping information to be assigned to $route.current on route match.

    Object properties:

    • controller{(string|Function)=} – Controller fn that should be associated with newly created scope or the name of a registered controller if passed as a string.
    • controllerAs{string=} – An identifier name for a reference to the controller. If present, the controller will be published to scope under the controllerAs name.
    • template{(string|Function)=} – html template as a string or a function that returns an html template as a string which should be used by ngView or ngInclude directives. This property takes precedence over templateUrl.

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

      • {Array.<Object>} - route parameters extracted from the current $location.path() by applying the current route

      One of template or templateUrl is required.

    • templateUrl{(string|Function)=} – path or function that returns a path to an html template that should be used by ngView.

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

      • {Array.<Object>} - route parameters extracted from the current $location.path() by applying the current route

      One of templateUrl or template is required.

    • 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 $routeChangeSuccess event is fired. If any of the promises are rejected the $routeChangeError event is fired. For easier access to the resolved dependencies from the template, the resolve map will be available on the scope of the route, under $resolve (by default) or a custom name specified by the resolveAs property (see below). This can be particularly useful, when working with components as route templates.

      Note: If your scope already contains a property with this name, it will be hidden or overwritten. Make sure, you specify an appropriate name for this property, that does not collide with other properties on the scope.
      The map object is:
      • key{string}: a name of a dependency to be injected into the controller.
      • factory - {string|Function}: If string then it is an alias for a service. Otherwise if function, then it is injected and the return value is treated as the dependency. If the result is a promise, it is resolved before its value is injected into the controller. Be aware that ngRoute.$routeParams will still refer to the previous route within these resolve functions. Use $route.current.params to access the new route parameters, instead.
    • resolveAs - {string=} - The name under which the resolve map will be available on the scope of the route. If omitted, defaults to $resolve.

    • redirectTo{(string|Function)=} – value to update $location path with and trigger route redirection.

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

      • {Object.<string>} - route parameters extracted from the current $location.path() by applying the current route templateUrl.
      • {string} - current $location.path()
      • {Object} - current $location.search()

      The custom redirectTo function is expected to return a string which will be used to update $location.url(). If the function throws an error, no further processing will take place and the $routeChangeError event will be fired.

      Routes that specify redirectTo will not have their controllers, template functions or resolves called, the $location will be changed to the redirect url and route processing will stop. The exception to this is if the redirectTo is a function that returns undefined. In this case the route transition occurs as though there was no redirection.

    • resolveRedirectTo{Function=} – a function that will (eventually) return the value to update $location URL with and trigger route redirection. In contrast to redirectTo, dependencies can be injected into resolveRedirectTo and the return value can be either a string or a promise that will be resolved to a string.

      Similar to redirectTo, if the return value is undefined (or a promise that gets resolved to undefined), no redirection takes place and the route transition occurs as though there was no redirection.

      If the function throws an error or the returned promise gets rejected, no further processing will take place and the $routeChangeError event will be fired.

      redirectTo takes precedence over resolveRedirectTo, so specifying both on the same route definition, will cause the latter to be ignored.

    • [reloadOnUrl=true] - {boolean=} - reload route when any part of the URL changes (including the path) even if the new URL maps to the same route.

      If the option is set to false and the URL in the browser changes, but the new URL maps to the same route, then a $routeUpdate event is broadcasted on the root scope (without reloading the route).

    • [reloadOnSearch=true] - {boolean=} - reload route when only $location.search() or $location.hash() changes.

      If the option is set to false and the URL in the browser changes, then a $routeUpdate event is broadcasted on the root scope (without reloading the route).

      Note: This option has no effect if reloadOnUrl is set to false.
    • [caseInsensitiveMatch=false] - {boolean=} - match routes without being case sensitive

      If the option is set to true, then the particular route can be matched without being case sensitive

    Returns

    Object

    self

  • otherwise(params);

    Sets route definition that will be used on route change when no other route definition is matched.

    Parameters

    Param Type Details
    params Objectstring

    Mapping information to be assigned to $route.current. If called with a string, the value maps to redirectTo.

    Returns

    Object

    self

  • eagerInstantiationEnabled([enabled]);

    Call this method as a setter to enable/disable eager instantiation of the $route service upon application bootstrap. You can also call it as a getter (i.e. without any arguments) to get the current value of the eagerInstantiationEnabled flag.

    Instantiating $route early is necessary for capturing the initial $locationChangeStart event and navigating to the appropriate route. Usually, $route is instantiated in time by the ngView directive. Yet, in cases where ngView is included in an asynchronously loaded template (e.g. in another directive's template), the directive factory might not be called soon enough for $route to be instantiated before the initial $locationChangeSuccess event is fired. Eager instantiation ensures that $route is always instantiated in time, regardless of when ngView will be loaded.

    The default value is true.

    Note:
    You may want to disable the default behavior when unit-testing modules that depend on ngRoute, in order to avoid an unexpected request for the default route's template.

    Parameters

    Param Type Details
    enabled
    (optional)
    boolean

    If provided, update the internal eagerInstantiationEnabled flag.

    Returns

    *

    The current value of the eagerInstantiationEnabled flag if used as a getter or itself (for chaining) if used as a setter.

Properties

  • caseInsensitiveMatch

    A boolean property indicating if routes defined using this provider should be matched using a case insensitive algorithm. Defaults to false.
