Faraday Em::Http adapter

This gem is a Faraday adapter for the Em::Http::Request library. Faraday is an HTTP client library that provides a common interface over many adapters. Every adapter is defined into its own gem. This gem defines the adapter for Em::Http::Request.

Installation

Add these lines to your application's Gemfile:

gem 'faraday-em_http'

And then execute:

$ bundle install

Or install them yourself as:

$ gem install faraday-em_http

Usage

This adapter can be used to make parallel requests using EventMachine.

The major difference between this and Faraday Em::Synchrony adapter is that it does not use fibers.

Error handling and responses have a slightly different behaviour and structure in some cases. Please run thorough testing scenarios, including connection failures and SSL failures

Base request

require 'faraday/em_http'

conn = Faraday.new(...) do |f|
  # no custom options available
  f.adapter :em_http
end

Parallel Requests

require 'faraday/em_http'

urls = Array.new(5) { 'http://127.0.0.1:3000' }

conn = Faraday::Connection.new do |builder|
  builder.adapter :em_http
end

begin
  conn.in_parallel do
    puts "Parallel manager: #{conn.parallel_manager}"

    @responses = urls.map do |url|
      conn.get(url)
    end
  end
end

# Gather responses outside of block
puts @responses.map(&:status).join(', ')
puts @responses.map(&:status).compact.count

Development

After checking out the repo, run bin/setup to install dependencies. Then, run bin/test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.

Contributing

Bug reports and pull requests are welcome on GitHub.

License

The gem is available as open source under the terms of the license.
