The Enhanced Ember Application Blueprint

Ember-CLI-Opitionated (ECO) provides an answer to several common decisions you face during development by bringing the best community addons under a single package. If you've ever asked yourself any of the following questions, ECO has you covered:

  1. SCSS vs LESS vs CSS?
  2. How can we get code coverage?
  3. How do we put styles in our pods?
  4. How can we track performance and feature usage?
  5. What's the best way to do date parsing/formatting in Ember?
  6. How can we implement feature flags?
  7. When will Rick Rolling stop being a thing?

...and more!

All you have to do is sit back, relax, and let ECO do the hard work. When it's done, you'll have the most badass skeleton app around; it'll be a lean, mean, code-generating machine! Watch your productivity increase and your architecture meetings decrease, all at the same time.


Note: This addon works best with the master branch of Ember CLI (as of 1.13.8), thanks to the enhancements of this Pull Request. ECO has a fallback to work with older versions (pre-2.0), but it is less reliable than the newer methods.

The following command will install this addon and run the included blueprint to give you maximum awesomeness:

ember install ember-cli-opinionated

Subsequent updates to this addon can be pulled in by updating the version of this package and running the following:

ember g ember-cli-opinionated

This will execute the included blueprint, setting up your app for the win! If you want to enhance your app configuration with some additional awesomeness, simply say yes to the first question to fill out a short questionnaire that will allow us to improve your app even more.

Once you have installed this package, you may need to go through some minor setup to begin utilizing the included addons. For most addons, however, you should be able to reap their benefits right away. Please refer to the sections below and the individual READMEs for information on each addon's setup (where applicable).


ECO's blueprint relies on addAddonsToProject, a new feature to Ember CLI. For older Ember CLI versions (<=1.13.8), a polyfill has been provided by chaining addAddonToProject within the blueprint. However, there are some slight problems with how that works, and some packages may not be properly saved to your package.json and bower.json. Feel free to use this addon regardless, but check to make sure the dependencies are saved.

Each of the included addons has its own compatibility with different versions of Ember, Ember CLI, and so on. We recommend checking the individual repositories for more information to make sure your app is compatible with the latest versions of each project. The intent of this addon is to enhance a brand-new app generated with Ember CLI, but that doesn't mean you can't juice up your existing application, either!

At this time, Ember 1.13+ should be supported by all included addons. Earlier versions of Ember may also be supported, but they have not been explicitly tested. If you are on 1.12-, please test and let us know if there are issues.

Note: A bug in Ember CLI causes npm to attempt installing ember-cli-sass multiple times. This will throw a large number of concerning-looking errors to your console but should not cause any real problems with installation.

What's Inside The Box?

Below you will find described the various addons packed into ECO.

Each addon is listed with a short description, a link to the main repositories, a setup rating and any additional dependency the addon might install. Optional dependencies that are included by our Enhanced Setup will be labeled as Enhanced with the name of their associated config.

Some of these additional projects may be WIP, alpha, or otherwise experimental. You should be able to use them for developing new applications, as long as you are aware of this fact.

Our rating system for additional setup needed to use an addon is as follows:

No Setup - You can begin using this addon immediately without any additional configuration necessary.

Trivial Setup - You may have to add 1-2 easy lines of code to complete setup.

Minor Setup - A bit of configuration is required (usually in config/environment.js), but the process is straightforward and explained in its README.

Major Setup - A significant amount of work is needed to use this addon. Our goal is not to include any projects that would receive this rating, as it is counter-intuitive to the quick-start nature of this project.
