Load jQuery from CDN in production and use local copy in development. jQuery CDN supports Ruby on Rails, Sinatra ans other non-Rails environments with Sprockets.
Another gem jquery-rails contain also UJS adapter for jQuery. So it need to test any jQuery updates and release new jQuery version after few month (for example, there is still no jQuery 2 for
jquery-ujs). If you don’t need UJS, this gem will be better to you.
jQuery CDN now has 2 branches: with jQuery 2.x and 1.x.
- Load from CDN
- Latest version of jQuery
- Gem version is same that jQuery
- Sinatra and plain Ruby support
- Multiple CDNs support
- Application environment support
