uniplaces-ember-responsive v2.0.5

ember-responsive

ember-responsive is an ember-cli addon that give you a simple, Ember-aware way of dealing with media queries.

All you need to do is tell it your application's breakpoints and it'll expose the rest for you. Here is an interactive demo

Requirements

ember-responsive needs window.matchMedia() to function, which isn't available in all browsers. Compatibility matrix

There is a polyfill by Paul Irish called matchMedia.js that will add support to older browsers

Getting Started

This is an ember-cli addon so, so all you need to do is

ember install ember-responsive

After that, simply register the breakpoints that are pertinent to your application in app/breakpoints.js:

export default {
  mobile:  '(max-width: 767px)',
  tablet:  '(min-width: 768px) and (max-width: 992px)',
  desktop: '(min-width: 993px) and (max-width: 1200px)',
  jumbo:   '(min-width: 1201px)'
};

This default config has already been provided for you. If you wish to change the values or add new ones, simply create a new app/breakpoints.js in your project and export your chosen config.

You can then query those breakpoints in your controllers, components, routes, and views:

this.get('media.isMobile'); // => true

Obviously, these properties also propagate to templates:

{{#if media.isDesktop}}
  Desktop view!
{{/if}}

You should also bind the list of active media queries to your app's rootElement. This means you won't have to deal with complicated media queries in CSS, instead simply use classes to style the different devices.

In your application.hbs template:

<div class="{{media.classNames}}">
  {{outlet}}
</div>

Injection

By default, this addon will generate an initializer in app/initializers/responsive.js that injects the media service app-wide. If the media property conflicts with other addons or you wish to use manual injection (Ember.service.inject) you can override this file.

Updating to 2.x

When updating this addon, make sure to run the generate command. Choose no to overriding existing files, unless you want the defaults. This command has to be run when updating to 2.x if your application relies on automatic injection. Because as of version 1.2.9, the addon will generate an initializer to allow users to customize injection.

ember g ember-responsive

Testing Helpers

This project provides several testing helpers to assist in testing content specific to different breakpoints.

Acceptance Tests

This project provides an acceptance testing helper to assist in testing content specific to different breakpoints.

To use the setBreakpoint helper in an acceptance test:

test('example test', function(assert) {
  setBreakpoint('mobile');
  visit('/');

  andThen(function() {
    // assert something specific to mobile
  });
});

The default breakpoint for testing defaults to desktop. You can modify this by changing _defaultBreakpoint in tests/helpers/responsive.js.

Integration Tests

Since the entire application isn't spun up for an integration tests, the setBreakpoint acceptance test helper won't work. In this case, you'll need to use the setBreakpointForIntegrationTest helper.

To use the setBreakpointForIntegrationTest helper in an integration test:

import { moduleForComponent, test } from 'ember-qunit';
import hbs from 'htmlbars-inline-precompile';
import { setBreakpointForIntegrationTest } from 'your-app-name/tests/helpers/responsive';

moduleForComponent('foo-bar', 'Integration | Component | foo bar', {
  integration: true
});

test('it renders', function(assert) {
  setBreakpointForIntegrationTest(this, 'mobile');
  this.render(hbs`{{foo-bar media=media}}`); // IMPORTANT: you must pass the media service

  // assert something specific to mobile
});

Tests

To run the tests, after cloning do:

npm install
bower install
npm test
