Ember Freestyle

Build Status npm version Download count all time Ember Observer Score

Ember Freestyle is an Ember addon that allows you to quickly create a component explorer for your Ember app.


This README provides a lightweight overview of Ember Freestyle to get you going. More complete documentation can be found at

Live Demo

Compatibility & support


  • For Ember versions >= 2.4, use the latest published version
  • For Ember versions 1.13.0 through < 2.4, use ember-freestyle 0.3.0


Ember Freestyle support is only provided for the 2 latest Ember versions


This installation process is opinionated in order to get you going quickly.

  1. ember install ember-freestyle

    This will do the following:

    • Install the ember-freestyle addon itself
    • Add a freestyle template in your app
    • Add a freestyle controller in your app

    Note: Ember CLI versions < 0.2.3 should use ember install:addon instead of ember install

  2. Add this.route('freestyle'); to your router.js file

  3. Navigate to /freestyle. You should now see something like:

All of the generated output is optional. If you don't want a freestyle route, for example, feel free to get rid of it in and add a freestyle-guide somewhere else in your app.

You can use the freestyle-guide component anywhere you'd like in your app. You can organize your components into multiple Freestyle guides if you want to. You can even use the constituent components like freestyle-usage on their own.

Problems? No problem.

Hopefully the installation instructions got you off to a smooth, seamless start. If you have any problems, feel free to chat with us in the Ember Community Discord or open an issue. As always, PRs are welcome!

Removing Ember Freestyle from Your Production Payload

We recommend blacklisting Ember Freestyle for production builds using Ember CLI's addon blacklist feature.

var environment = process.env.EMBER_ENV;
var pluginsToBlacklist = environment === 'production' ? ['ember-freestyle'] : [];

module.exports = function(defaults) {
  var app = new EmberApp(defaults, {
    addons: {
      blacklist: pluginsToBlacklist

Using Ember Freestyle Within an Addon

Dependency Configuration

You should include Ember Freestyle as a devDependency so that apps using your addon will not include Ember Freestyle CSS and JavaScript in their production payloads.

Code Snippets

You will need to tell the build where to search for code snippets as follows:

var app = new EmberAddon(defaults, {
  // ...
  freestyle: {
    snippetSearchPaths: ['addon', 'tests/dummy/app']


Running Tests

  • npm test (Runs ember try:each to test your addon against multiple Ember versions)
  • ember test
  • ember test --server


  • ember build

If you are a project maintainer, run ./script/release [major|minor|patch] to release a new version of this addon. We use under the hood to generate the changelog.

You can’t perform that action at this time.
