Any way to avoid duplication between git repos

[justin808]

I noticed that the jquery-ujs is in 2 places on github:

• https://github.com/rails/jquery-rails/blob/master/vendor/assets/javascripts/jquery_ujs.js
• https://github.com/rails/jquery-ujs/blob/master/src/rails.js
• How are these kept in sync?
• Are there advantages (or necessities) doing it this way?
• In the long term, should the duplication be avoided, and maybe jquery-rails could refer to the version number?

One is the source code other is the packaged version.

How are these kept in sync?

They don't need to. Only when we need to release a new version of jquery-rails https://github.com/rails/jquery-rails/blob/04fcfa29b859eef9479f89b6a799d00212902385/Rakefile#L53-L57.

Are there advantages (or necessities) doing it this way?

We decouple the development of jquery-rails and jquery-ujs. So we don't need to have things like upgrading jquery version on the jquery-ujs repository.

In the long term, should the duplication be avoided, and maybe jquery-rails could refer to the version number?

I don't see why. It already refer to the version number.
