Faraday Middleware

A collection of useful Faraday middleware. See the documentation.

gem install faraday_middleware

⚠️ DEPRECATION WARNING ⚠️

As highlighted in Faraday's UPGRADING guide, faraday_middleware is DEPRECATED, and will not be updated to support Faraday 2.0. If you rely on faraday_middleware in your project and would like to support Faraday 2.0:

• The json middleware (request and response) are now both bundled with Faraday 🙌
• The instrumentation middleware is bundled with Faraday
• All other middlewares, they'll be re-released as independent gems compatible with both Faraday v1 and v2, look for awesome-faraday

Most of the middlewares are up for adoption, contributors that would like to maintain them. If you'd like to maintain any middleware, have any question or need any help, we're here! Please reach out opening an issue or a discussion.

Dependencies

Ruby >= 2.3.0

As of v0.16.0, faraday and faraday_middleware no longer officially support JRuby or Rubinius.

Some dependent libraries are needed only when using specific middleware:

Middleware	Library	Notes
FaradayMiddleware::Instrumentation	activesupport
FaradayMiddleware::OAuth	simple_oauth
FaradayMiddleware::ParseXml	multi_xml
FaradayMiddleware::ParseYaml	safe_yaml	Not backwards compatible with versions of this middleware prior to faraday_middleware v0.12. See code comments for alternatives.
FaradayMiddleware::Mashify	hashie
FaradayMiddleware::Rashify	rash_alt	Make sure to uninstall original rash gem to avoid conflict.

Examples

require 'faraday_middleware'

connection = Faraday.new 'http://example.com/api' do |conn|
  conn.request :oauth2, 'TOKEN'
  conn.request :json

  conn.response :xml,  content_type: /\bxml$/
  conn.response :json, content_type: /\bjson$/

  conn.use :instrumentation
  conn.adapter Faraday.default_adapter
end
