Standard way to include Javascript files in app?

Question

Say that I have pulled a fancy.js file from somewhere online, what are the steps that I should take to include it in my Rails 4 application?

Right now I have the following

1. Move fancy.js to assets/javascripts folder
2. add //= require fancy to application.js asset pipeline
3. ???

Are there more steps after 1 and 2, or am I doing this all wrong to begin with?

Answer 1

Looks like you are on the right path. Take a look inside app/assets/javascripts/application.js

When you created a new app (i.e., rails new app_name), it should have added

//= require_tree .

Simply add references to additional javascript files you wish to include.

EXAMPLE

//= require jquery
//= require jquery-ui
//= require jquery_ujs
//= require fancy
//= require_tree .
