Build Status Gem Version

OpenComponents for Rails. This gem provides view helper methods for component rendering on both server- and client-side.

Getting Started

Add the gem to your Gemfile and run bundle install:

gem 'opencomponents-rails'


All configuration options are set through Rails environment configuration files.

# production.rb

# Sets the registry URL to fetch components from. Defaults to http://localhost:3030.
config.opencomponents.registry = 'http://my.awesome.registry'

# Determines whether rendering should be handed off to the browser if server-side
# rendering fails. Defaults to true.
config.opencomponents.enable_client_failover = true

# Sets the timeout length (in seconds) for registry requests. Defaults to 5.
config.opencomponents.request_timeout = 10


OpenComponents::Rails supports both server- and client-side rendering of components. By default, the gem will fall back to client-side rendering if a server-side registry request times out. If client-side failover if disabled, an error will be raised instead. This is configurable using the enable_client_failover option.

Client-Side Rendering

The OpenComponents client-side javascript library is bundled with this gem for inclusion in the asset compilation process. To enable client-side rendering through the asset pipeline, add the library to your javascript manifest:

//= require opencomponents

Once that's done, you can use the oc_component_tag method in your views. You can either pass the method a fully formed href attribute or use the same options as OpenComponents Renderer.

<%= oc_component_tag('my-sweet-component', href: 'http://localhost:3030/my-sweet-component/1.0.1?name=Zan') %>

<%= oc_component_tag('my-sweet-component', params: {name: 'Zan'}, version: '1.0.1') %>

Components using this tag will be automatically rendered on DOM load.

Server-Side Rendering

In your view, simply call render_component:

<%= render_component('my-sweet-component', params: {name: 'Zan'}, version: '1.0.1') %>

The method accepts the same options as the OpenComponents Renderer.
