Get current route name in Ember

I need to get the current route name in my ember application; I tried this: Ember App.Router.router.currentState undefined but it doesn't work for me (there is probablig something i'm missimg...) I use Ember rc6 and I have a multilingual app; in the applicationRoute I detect the browser's language and I redirect to the correct page with:

this.transitionTo(userLang);

but I would like this to be executed only when user are on the home page, so something like this:

if (currentRoute == 'home'){
  this.transitionTo(userLang)
}

this worked for me on the route.js file: this.controller.target.currentPath

NOTE: as of Ember 3.16, the original answer is not only recommended, but observers are strongly discouraged.

To get the current route name, you can utilize the Router Service: https://api.emberjs.com/ember/3.18/classes/RouterService/properties/currentRouteName?anchor=currentRouteName

export default class MyComponent extends Component {
  @service router;

  get activeRoute() {
    return this.router.currentRouteName;
  }
}

Original answer below

You could observe the application's currentPath and set it to the current route accordingly when it changes:

App = Ember.Application.create({
  currentPath: '',
});

App.ApplicationController = Ember.Controller.extend({
  updateCurrentPath: function() {
    App.set('currentPath', this.get('currentPath'));
  }.observes('currentPath')
}),

This way you have access to the currentPath when ever you want with App.get('currentPath');

E.g.

if (App.get('currentPath') == 'home'){
  this.transitionTo(userLang);
}

Hope it helps.

Ember has a RouterService since 2.15. It provides the name of the current route as currentRouteName property. A polyfill exists for Ember 2.4 - 2.14 if you are still on such an old version.

import Component from '@ember/component';

export default Component.extend({
  router: service(),

  isHomeRoute: computed('router.currentRouteName', function() {
    return this.router.currentRouteName === 'home';
  }),
});

All other solutions mentioned here are relying on private API that might already be deprecated / removed. Using RouterService is working at least up the current version, which is 3.12 at the time of writing this.

Please note that the "home" is not /. The root URL is called "index".

This worked for me on 1.3.0-beta (and a quick glance at the source for 1.1.2 suggests it would work there too):

App.__container__.lookup('router:main').location.lastSetURL

Note that the documentation states:

At present, it relies on a hashchange event existing in the browser.

However, I believe it's strongly suggested that App.__container__ not be used in production code. A more acceptable alternative would be to use App.Router.router.currentHandlerInfos, which provides information on the current Ember route.

Yet another option is currentRouteName on the ApplicationController. You can add needs: ['application'] to your controller, then access the route name with controllers.application.currentRouteName. This will return something like posts.index.

If you want to get current route in your component or controller you can inject routing service (routing: Ember.inject.service('-routing'))

(for more) and use:

this.get('routing.currentRouteName') or this.get('routing.currentPath')

Example with component and computed property:

import Ember from 'ember';

export default Ember.Component.extend({
  routing: Ember.inject.service('-routing'),

  checkMyRouteName: Ember.computed('routing.currentRouteName',  function() {
    return this.get('routing.currentRouteName');
  })
})

Example with controller and computed property:

import Ember from 'ember';

export default Ember.Controller.extend({
  routing: Ember.inject.service('-routing'),

  checkMyRouteName: Ember.computed('routing.currentRouteName', function() {
    return this.get('routing.currentRouteName');
  })
})

Current route in your route you just need this.routeName

Example with route:

import Ember from 'ember';

export default Ember.Route.extend({
  checkMyRouteName() {
    return this.routeName;
  }
})

The Ember namespace API now has a getOwner method, which is very useful for looking up the currentRouteName, or, other route properties.

  const owner        = Ember.getOwner(this);
  const currentRoute = owner.lookup('router:main').currentRouteName;
  const routeInfo    = owner.lookup(`route:${currentRoute}`).get('info');
  // etc.

I've created an Ember Twiddle example to demonstrate. Use the text input above the "Output" pane to hit other routes like /blue, /green, or /red.

I had the same problem for a while. then i started exploring router. It always have a state object which can be obtained from any route using 

var route = this;
var handlerInfos = route.get("router.router.state.handlerInfos");
var currRouteHandlerInfo = handlerInfos[handlerInfos.length-1];
var currRouteName = currRouteHandlerInfo.name; //"home"

that's it. Now you have the current route name!

if you want the current route params,

var routerParams = this.get("router.router.state.params");
var currRouteParams = routerParams[currRouteName]; //{ homeId : "1" }

With the shift to components, it is harder to get route name. The best way is to add an initializer such as 

ember g initializer router

(from command line), and

export function initialize(application) {
  application.inject('route', 'router', 'router:main');
  application.inject('component', 'router', 'router:main');
}

export default {
  name: 'router',
  initialize
};

in a initializers/router.js. You can also inject into controller if you need to. Then just do simply 

this.get('router.currentRouteName');

in JS, or 

{{router.currentRouteName}}

in template.

This is the only way I have found to get it reliably, and observable in Ember 2.4

You can simple parse the current URL. This way you can use your full url for example:

http://127.0.0.1:8000/index.html/#/home

and extract from this string the suffix:

/home

which is the current route name.

A simple JS function (that works regardless to your Ember version) will be: 

function getCurrentRoute()
{
    var currentRoute;
    var currentUrl = window.location.href; // 'http://127.0.0.1:8000/index.html/#/home'

    var indexOfHash = currentUrl.indexOf('#');
    if ((indexOfHash == -1) ||
        (indexOfHash == currentUrl.length - 1))
    {
        currentRoute = '/';
    }
    else
    {
        currentRoute = currentUrl.slice(indexOfHash + 1); // '/home'
    }

    return currentRoute;
}

Example of use:

if (getCurrentRoute() == '/home')
{
// ...
}

Just as an update, in Ember 1.8.1, we can get the routeName inside an Ember.Route object by doing this.routeName.

Currently as of Ember 1.7.0 you can get the current route from within a route by calling this.routeName.
