An Ember CLI addon to easily add <link> tags to the head of a HTML document.

There may be many reasons to define a link between a HTML document and an internal or external resource. One reason is to provide search engines and SEO tools the best URL when there are several choices. This can occur for example when there are multiple variants of the same resource. This addon allows you to define these links statically or dynamically when transitioning between routes.

This addon is ideal for use with SEO tools such as MOZ to significantly improve impressions on Google and other search engines whilst reducing situations where content is mistakenly conceived as duplicate.

• Ember.js v2.18 or above
• Ember CLI v2.13 or above

From within your Ember CLI project directory run:

ember install ember-cli-link-tags

To use this addon you must include the Linkable mixin within the routes you intend to define links. The mixin allows you to define links as plain JavaScript Objects (POJOs) returned from a links method that runs within the context of the route.

Link tags are described as key/value pairs of attributes that may be formed dynamically using the model defined on the route or any other attributes set on the controller. The links function returns a plain JavaScript object with the appropriate key/value pairs.

// app/routes/posts.js
import Route from '@ember/routing/route';
import Linkable from 'ember-cli-link-tags/mixins/linkable';

import { get } from '@ember/object';

export default Route.extend(Linkable, {
  links() {
    return {
      canonical: '/posts',
      next: '/posts?page=' + get(this, 'controller.nextPage')
    };
  }
});

This will add the canonical and next link tags to the head of the document. The value of nextPage is taken from the controller and appended to the end of the next value. Of course the key/value pairs returned by the function can be whatever you want and application specific.
