如何从浏览器控制台中进行Ember.version（）的Ember？

Question

I was studying Javascript / Ember and I was looking into its source codes. https://github.com/emberjs/ember.js/

While I was studying, I found something interesting and I wonder how it works. As you may know, you can get version number of Ember if you type Ember.VERSION in the browser console. I wanted to do in my project so I started searching codes how Ember did it.

I could find

// in packages/ember/lib/index.js
Ember.VERSION = VERSION;
...
// Later exports Ember object

However I can't find how Ember makes it available in window (from browser). I expected they did like... window['Ember'] = Ember or something like that but I couldn't find any similar codes.

I wonder if there is anyone knows how they make Ember object available throughout window. Thank you so much!

ember-cli-app-version addon can expose your application's name and version info. So you can put your version in your templates via an helper .

The addon also registers the infos to the Ember.libraries so that ember-inspector can understand. You can access the Ember.libraries in a such way:

Ember.libraries._registry.filter(item=>{return item.name==='my-app-name';})[0].version

The addon can give you both package.json information or git describe result.
