ember-page-title Ember Observer Score CI

This addon provides a helper for changing the title of the page you're on.

Installing via ember-cli

ember install ember-page-title

Compatibility

  • Ember.js v3.16 or above
  • Ember CLI v2.13 or above
  • Node.js v10 or above
Fastboot vs Non-Fastboot Notes

Post Install Setup Notes

As of v3.0.0 this addon maintains the page title by using the <title> tag in your document's <head>. This is necessary for FastBoot compatibility.

Non-fastboot apps should keep the <title> tag in index.html to ensure that the initial page is valid HTML. The title will be removed and replaced when your app boots.

Fastboot apps MUST remove the <title> tag from index.html. As of v6.0.0 this is done automatically if you use ember install ember-page-title to install this addon. Can also be run manually using ember g ember-page-title to update the title if FastBoot is installed.

API

{{page-title}} Helper

attribute type default description
separator string " | " Which separator should be displayed after this instance of {{page-title}}
prepend boolean true If the token should be prepended or appended to the list of tokens
replace boolean false Replace all previous elements with the active
front boolean false If the token should always be in the beginning of the resulting title.

These defaults are configurable in config/environment.js:

// config/environment.js

module.exports = function (environment) {
  let ENV = {
    pageTitle: {
      replace: true,
    },
  };

  return ENV;
};

page-title Service

If you want to be notified when the page title has been updated, you can extend and override the page-title service and provide your own titleDidUpdate hook. The titleDidUpdate hook receives the new title as its sole argument.

// app/services/page-title.js

import EmberPageTitleService from 'ember-page-title/services/page-title';

export default class PageTitleService extends EmberPageTitleService {
  titleDidUpdate(title) {
    // Do something with the new title.
  }
}

Testing

assert the page title with the supplied getPageTitle test helper:

import { getPageTitle } from 'ember-page-title/test-support';

module('Acceptance | Register Page', function(hooks) {
  setupApplicationTest(hooks);

  test('visiting /register', async function(assert) {
    const registerURL = '/register';
    await visit(registerURL);

    assert.equal(currentURL(), registerURL);
    assert.equal(getPageTitle(), 'Register | Some Website');
  });
});

Upgrading notes for 5.x to 6.x

  • ember-page-title no longer requires the usage of ember-cli-head. Please remove {{head-layout}} from your application's application.hbs route template.
  • {{title}} has been removed, please rename to {{page-title}}.
