batman.js

We’ve tried to make batman.js’s installation process as simple as possible. There’s two main ways to go about it: using the batman-rails gem or downloading the Starter Package.

1. batman-rails

batman-rails is a Ruby Gem which allows you to easily use batman.js inside a Rails 3.2 or 4.0 application. It takes care of a number of things for you:

• Vendoring the batman.js source into your app
• Generating your project structure within your Rails app
• Setting up JSON communication between your Rails and batman.js app

1.1 Get the Gem

Getting the gem is simple. Simply add the following line to your Gemfile:

gem 'batman-rails'

Then simply tell bundler to install it:

$ bundle install

1.2 Create a batman.js application

Now that batman-rails is installed, we can use the normal Rails generator system to generate the skeleton for our batman.js application.

$ rails generate batman:app

The structure of this app will be exactly the same as described in Directory Structure, but it will live within our Rails app folder. You can find your newly created app in MyApp/app/assets/batman.

2. Starter Application

If you’re not using Rails, you can download either the Starter Application or simply a copy of batman.js itself. The Starter Application is simply a zip file which contains an empty batman.js project, very similar to what batman-rails would generate for you. It will contain all of the directories your project needs (described further in Directory Structure), in addition to the actual batman.js source.

You can simply download the zip and start filling it with your own application code.

3. That’s it!

Whichever way you choose, that’s all there is to it!
