RestClient Adapters

RestClient Adapters

This gem allows to use different HTTP implementation in RestClient with next adapters:

• :net_http - Net::HTTP (default, blocking I/O)
• :em_http - EventMachine::HttpRequest (non-blocking I/0)

Installation

Add this line to your application's Gemfile:

gem 'rest-client-adapters'

And then execute:

$ bundle

Or install it yourself as:

$ gem install rest-client-adapters

Usage

You may specify adapter for each request:

RestClient.get('https://www.google.com')
RestClient.get('https://www.google.com', adapter: :em_http)

Or you may specify adapter globaly:

RestClient.adapter = :em_http
RestClient.get('https://www.google.com')

Notes

When EventMachine is already running we assume that you are responsible for Fiber allocation. You can add Rack::FiberPool to your application middleware and it automatically provides a Fiber for each incoming HTTP request. It creates pool of Fibers and re-use fiber for each incoming HTTP request. Also you can control the connection pool size.
