You interface with goliath by writing one of the following three:

• Goliath::API classes define the endpoint of a route. Each must be named for its file (eg. foo_muncher.rb must define FooMuncher < Goliath::API), and must define a response method. You need at least one of these per project, and can assemble multiple endpoints using rack routes.
  • See the code for many examples.
  • How to perform Asynchronous-Processing of HTTP, MySQL and more.
  • HTTP Streaming endpoints

• Middlewares decorate the response with before, around or after actions (eg validating an API key, logging a call, wrapping a JSON-P callback). They follow the familiar Rack middleware paradigm of initialize and call (returning [status,headers,body]). PLEASE NOTE however an important difference in how you delegate down the chain — the Writing your own middleware section explains more, and see the middleware examples

• Plugins add code that share the reactor but are outside the response flow of any particular HTTP request. For example, you might use an EventMachine periodic time to send a heartbeat log message or metrics to your graphite server. For an example that periodically records the reactor latency, see the plugin examples
