If you start a new Ember project today, or want to try Ember and compare it with other frameworks, please use Ember-CLI: http://ember-cli.com/ http://ember-cli.com/ The style of development CLI introduces makes you incredibly productive. A comparison of Ember without discussing CLI is missing an essential ingredient.
- sergiotapia 12y ago
  Not only is it productive, it is officially endorsed by the Ember core team as the "right way" to use Ember.

    Not only it is endorsed, it is Ember. The project will get lifted to Ember in github by the time Ember 2 comes around

      Where can I find more info on Ember 2 roadmap? Thank you.

  Thanks for the heads-up, maybe I can do a follow-up article or add an update into this one to include ember-cli features.

  I really dislike having to start up a separate web server for every project I work on.

The article talks about SPAs, but doesn't go so far as suggesting that an Ember or Angular app could be a separate project altogether from the rails app, requiring no integration with rails, using the back end only as a REST api and serving the static SPA from wherever (say a CDN). There are tradeoffs with this approach, but some would consider this even easier or simpler than having the html/js app 'integrated' with the back end.

  This is the direction we're moving on my company, we have group building a restful API, and then we have the front end team that are essentially their first client of the API. So far it's been an extremely positive experience, in the past the "front end" team was expected to dig in to the back end and build out the data collection themselves, now we can have multiple teams working on the same thing without stepping on each others toes because we know where demarcation point of the responsibilities are.

    May I know, how do you guys handle authentications and "cookies"/tokens?
    - Siecje 12y ago
      Accept authentication using HTTP-BasicAuth and create a token then use the token until it expires.

      You might be interested in https://github.com/lynndylanhurley/ng-token-auth https://github.com/lynndylanhurley/ng-token-auth and https://github.com/lynndylanhurley/devise_token_auth https://github.com/lynndylanhurley/devise_token_auth, which together collect (what seem to be) best practices for both frontend and backend for token authentication. We're planning on using it for our startup.

    If you're gonna step to me, better make sure your framework game is tight.

  this is very old...lot has been changed for better in Ember and some what in Angular as well..

About the Angular portion of CSRF integration - one can do this in other ways without disabling the check. One can create a factory that acts as the http interceptor that has the csrf injected. One can also manually crawl the DOM by using document.querySelector and inject the value into the http interceptor for appending to requests. One can also use an http request to fetch the token and have the token served via the xhr and manually bootstrap the app. Angular is relatively unopinionated here.
- fervisa 12y ago
  In fact, the article mentions in 6.2.2 one client-side solution to handle CSRF token by including it into the $httpProvider's headers.

Why duplicate logic in the front end? We recently open sourced a lightweight framework for writing coffeescript in rails. It's fully compatible with turbolinks and let's you run only the JS you need. It's called RailsScript ( https://github.com/gemgento/rails_script https://github.com/gemgento/rails_script )
- acconrad 12y ago
  I'd love this if it had a testing framework to go with it. The primary reason we went with Angular was because it was so much easier to test than the spaghetti of jQuery modules and the mess that are events.
  - fervisa 12y ago
    I usually test my Rails/Angular projects with jasmine-rails jasmine-jquery and Sinon.JS. These three together let you test virtually any frontend js code.
  - cjjuice 12y ago
    Thanks for the feedback. This may be a good addition to RailsScript in the future. As always, pull requests are more than welcome

Is there any differentiation between the two on API stability? I got burned last fall trying to build an app with Ember as they kept making breaking changes, even between release candidates (!). Technically Ember was stable, but Ember Data (which is separate I guess?) was doing major refactoring on their API, and it cost us quite a bit of time just trying to keep up. Even today, their GitHub has a disclaimer that it's beta quality and under active development[1]. Ember CLI also says it's very much WIP[2], even though it seems to be the officially endorsed way to build Ember apps. Does Angular make stronger promises about their stability? Is this sort of thing just the cost of doing business with cutting-edge frameworks? Or am I missing something?

  It seems like it is a bad time for finding enterprise-grade js frameworks. Ember has its disclaimer, Angular is impossible to recommend for new projects since 2.0 isn't out yet and will be entirely different than 1.x, react/flux is still releasing breaking changes, and I'm not sure what else would be considered a very strong candidate.

Readability issue: On my iPhone 6 in landscape I can't read the first couple words of every line because of the stupid little popup menu bar anchored to the left. Put some padding on the text.
- aerosmile 12y ago
  Sorry for that. We are using an iPhone 5 for testing, and it seems that the larger iPhone 6 viewport is leading to some unexpected edge cases. We'll roll out a fix now and I will use this as an excuse to get a new phone :)
