Easier to define and more readable router for EmberJS with support for auto-updated document title based on each route.
npm install ember-enhanced-routerThis addon make it easier and more readable to define your application's router and let you have
dynamically updated document title depending on given title tokens in the router or the agglomerateddocumentTitleToken properties of each controller in the hierarchy of the current route.
The idea came first after using ember-cli-document-title
and finding it too complex to define the titles and not dynamic. I thought that the title tokens for
each route should be defined in the router instead of inside each route, and I also that using the
model as unique variable to create the title token of a route was not enough.
See the demo application there.
* npm install --save-dev ember-enhanced-router
* or, with the latest ember-cli: ember install:addon ember-enhanced-router
* First you need to define your router using the new helper provided, route. It basically defines
a new route. It takes 1, 2 or 3 arguments:
1. name and options path: The name of the route + @ + the path of the route. If there is no
@, the default path is the name of that route, or / if the name of the route is index.
2. titleToken: By default the title token is the humanized version of the route name, or
nothing if the route is the index route (path is / and it has no sub-routes. It can be:
- a string with optionals controller property names defined between {{ and }} to be
replaced with the route's corresponding controller properties.
- a function which will be defined as a volatile computed property within the context of
the controller (this in the function will be a proxy to the controller).
- a computed property which will be defined on the context of the controller too (this
will be a proxy to the controller and the dependant key will be relative to that controller)
- false to not included any title token for that route
- null will act as if you didn't give any title token (see this 2. header)
3. options: By default no options are given. For now there are 2 supported options:
- resetTitle: If set to true, the system will use all the title tokens until this route,
not the ones of the parent(s)
- asResource: If set to true, the route will be defined in ember router using
this.resource instead of this.route.
* Once you're done defining your routes, call .toRouter() to generate and export the router
expected by Ember. It'll use all the parameter to extend Ember.Router and create the Router, so
it's a good place to define for example the location type, and/or add some mixins such as Google
Analytics from ember-cli-google-analytics.
* To update the document.title automatically taking care of the bindings and all, you need to insert thedocument-title component in your application template: {{document-title}}. By default, it'll
not show anything, but you can set the display attribute in the hash to true or inline or any
css display attribute value.
* By default all title tokens will be collected in the current route's hierarchy and then joined from
the top most route to the application one. You can change this behavior by defining in the controller
of any route a documentTitleFormatter property being a function. From the top-most to the bottom-most
active route, the documentTitleFormatter property of the first associated controller will be the
one used to put together all the collected tokens.
It'll receive 2 arguments of type array. The first one will be all the collected non-empty tokens
from the application route to the top-most currently activate route. The second one is the same
but in reverse order. It could differ from .reverse() when the title token of a route is an array
instead of a string. This array itself is not reversed, but concatenated to the rest of the tokens.
There is nothing better than an example so here it is:
``js
import Ember from 'ember';
import config from './config/environment';
import route from 'ember-enhanced-router/route';
// if any controller.documentTitleToken exists, then it'll be used as the titleToken, except if
// the title has ben set to false in the router
// application route with title Ember Enhanced Router (null could be replaced with 'application')home
export default route(null, 'Ember Enhanced Router').routes( // this defines the sub-routes
// route with no title token and / as path
route('home@/', false),
// dashboard route with title token Dashboard and dashboard as path
route('dashboard'),
// members route with title token All Members and users as pathindex
route('members@users', 'All Members').routes(
// route with no title token and / as path (because index)/
// this line is optional as the system will automatically add it if it does not find any
// route with as path.
// But if you need to define a title to this route, you can do it here.
route('index'),
// show route with User title token and :user_id as path
route('show@:user_id', 'User {{name}}'),
// new route with New User title and new as path (the title will just be 'New User'resetTitle
// since we defined the option to true
route('new', 'New User', {resetTitle: true}),
// edit route with either Edit profile or Edit User title token and :user_id/edit as path
// the computed property has the controller as context
route('edit@:user_id/edit', function () {
if (this.get('model') === this.get('session.user')) {
return 'Edit Profile';
}
else {
return 'Edit User ' + this.get('name');
}
}.property('model', 'name', 'session.user'))
),
// the catchall route if necessary, with Nothing Here as the title``
route('catchall@*', 'Nothing Here!')
).toRouter({location: config.locationType});
