Can i start using Ember for my project today?


#1

I found this on documentation page under Model.

WARNING: EMBER-DATA IS A WORK IN PROGRESS AND UNDER RAPID DEVELOPMENT.

This makes me nervous to start using Ember for my new application. If i start using Ember at this stage, should i need to change my production code often. Is it safe to use Ember now?

Yes it is safe to use Ember today. That disclaimer is for Ember-Data which is part of the persistance mechanism. If you are nervous about using Ember-Data you can roll your own persistance mechanism using just Ember.Object and ajax calls, or there are others, such as Ember-Model

Discourse, which is this forum software powering discuss.emberjs.com is using Ember without Ember-Data

Edit: I also want to mention Ember.js Persistence Foundation which came out very recently

Yes and no - it depends™…

First the yes: As @RyanHirsch pointed out, the notice only applies to Ember-Data which is getting out of Alpha pretty soon if I am not mistaken… And Ember.js itself is solid. I did a little internal app just recently and it worked like a charm for me.

Now the no reasons: Ember.js is very young - not in the technical sense that there are bugs (there might very well be - but I didn’t hit any so far), but in the very real “I can Google my way to a solution sense”

Ember and it’s inner workings and APIs have been under a lot of flux while under development, and although public attention is good for a new project like this, in this case it also led to a ton of outdated or just plain wrong code examples, tutorials and blog posts on the web. Things that may have been applicable to rc3 don’t work the same way in rc5 and a lot of times authors did not include what version of the framework they wrote the article against.

It’s confusing as hell, especially since Ember.js is quite a bit of Architecture and Framework to wrap your head around - but it’s very worth it. Just don’t expect the level of documentation/tutorials and videos you’ll get for something like Rails or some new .NET Technology. Once you get a better understanding for the concepts you start to understand how things fit together and where you are supposed to fill in the blanks - but still then you’ll at times find yourself looking for guidance from running code like the excellent Discourse source or directly from the Ember.js code).

Do it - but be prepared for some challenges ahead.
