rjv (Rails Javascript Variables)

rjv is a set of helpers that can inject any variables from rails to your javascript code.

Usage

Add this code at the bottom of your layout file (before closing body tag).

= javascript_tag do
  !== vars = #{vars.to_json};

Now you can inject variables in your views:

- set_var 'someVar', 'someValue'

In javascript this variable will be available as:

console.log(vars.someVar)
