How to Add Meta Tag In Ember.js?

5 minutes read

To add a meta tag in Ember.js, you can use the HeadData service provided by Ember. First, import the HeadData service in the component or route where you want to add the meta tag. Then, use the setMeta method of the HeadData service to add the meta tag. Specify the name and content of the meta tag as arguments to the setMeta method. After adding the meta tag, it will be rendered in the <head> section of the HTML document when the component or route is rendered. Additionally, you can define meta tags in the head section of the app template file to apply them across all routes in your Ember.js application.

                title: 'Your OG Title Here'
            }
        });

How to test meta tags in ember.js?

To test meta tags in Ember.js, you can follow these steps:

  1. Install an addon like ember-cli-meta-tags (https://github.com/martndemus/ember-cli-meta-tags) which provides helpers for managing meta tags in Ember.js.
  2. Create a new test file (e.g., meta-tags-test.js) in the tests directory of your Ember.js app.
  3. In the test file, import the necessary modules and set up the test environment.
  4. Write test cases to check if the desired meta tags are present in the rendered HTML document.
  5. Use methods like assert.dom() from the ember-cli-page-object addon to assert the presence of meta tags in the DOM.
  6. Run the test suite using Ember CLI's test command to see if the tests pass.


Here's an example of how you can test meta tags in Ember.js using ember-cli-meta-tags addon:

module('Integration | Component | meta-tags', function(hooks) {
  setupRenderingTest(hooks);

  test('it renders meta tags correctly', async function(assert) {
    await render(hbs`{{meta-tags}}`);

    assert.equal($('.meta[name="description"]').length, 1, 'Description meta tag is present');
    assert.equal($('.meta[property="og:title"]').length, 1, 'Open Graph title meta tag is present');
    // Add more assertions for other meta tags as needed
