Rails 3.1+ asset-pipeline gem to provide riot.js

You should install nodejs for riot.js compilation work

Have in your Gemfile:

gem 'riotjs-rails'

And, have in your application.js manifest:

//= require riot

You can create a tag by including a file in app/assets/javascripts, this file must end with .tag.

The name of the file will be used as the tag name, so let's say we want to create a timer.tag.

All we need to do is create a file called app/assets/javascripts/timer.tag:

<timer>

  <p>Seconds Elapsed: { time }</p>

  this.time = opts.start || 0

  this.tick = function() {
    this.update({ time: ++this.time })
  }

  var timer = setInterval(this.tick.bind(this), 1000)

  this.on("unmount", function() {
    clearInterval(timer)
  })

</timer>

After, we mount the tag using riot.mount('timer') where we want to use it.

For instance in your application.js:

//= require jquery
//= require jquery_ujs
//= require riot
//= require_tree .

$(function() {
  riot.mount('timer');
});

And then include the tag adding <timer></timer> in your html.

You should see Seconds Elapsed: 0 changing the number after each second.
