webcomponentsjs-rails

webcomponents.js packaged for the Rails asset pipeline.

Add the gem to your Gemfile:

gem 'webcomponentsjs-rails'

Load assets from the library within an asset manifest such as application.js:

//= require webcomponentsjs-rails/MutationObserver

If you've included the gem in your Gemfile, Bundler will generally take care of requireing the necessary files, but if for some reason you need to manually require the gem:

require 'webcomponentsjs/rails'

The version number of the gem mirrors the version number of webcomponents.js. For example:

gem 'webcomponentsjs-rails', '1.1.1'

will add webcomponents.js version 1.1.1 to the asset pipeline.

Should a bug be discovered in the gem only, a fourth version identifier will be added and incremented.
