Rails Include Third Party Javascript Library File
assets, javascript, ruby-on-rails
Solution
Third party JavaScripts should go inside `vendor/assets/javascripts` directory, because `app/assets/javscripts` is for your application specific JavaScripts and `lib/assets/javascripts` is for your libraries code which is separate to your application or libraries that you have shared across different applications.
Please reference Asset Organization for further details.
As far as inclusion of javascripts in your application/page if you're using it only on a specific page then including the file with `javascript_include_tag` is the approach I would take as well.
Problem
I've got a Javascript library for AJAX file uploading that I need to include on only one page. Where is the best folder for this for file? `app/assets/javascripts`? `vendor/assets/javascripts`? `lib/assets/javascripts`? And then I need to be able to include it on only one page. Or should I just add it to `application.js` and have it included on every page (even know I'm only using it on one page?) I figured for performance my best bet would be to put the minified JS file somewhere, and just include it with a `javascript_include_tag` on the page I need it, by using `yield(:head)` and `content_for(:head)`? Thank you.
