Looking for Example of Faraday Middleware with Error checking

Faraday has an error handling middleware in by default:

faraday.use Faraday::Response::RaiseError

For example:

require 'faraday'conn = Faraday.new('https://github.com/') do |c|  c.use Faraday::Response::RaiseError  c.use Faraday::Adapter::NetHttpendresponse = conn.get '/cant-find-me' #=> gems/faraday-0.8.8/lib/faraday/response/raise_error.rb:6:in `on_complete': the server responded with status 404 (Faraday::Error::ResourceNotFound)

If you want to write your own middleware to handle HTTP status code responses, heres a basic example:

require 'faraday'class CustomErrors < Faraday::Response::Middleware  def on_complete(env)    case env[:status]    when 404      raise RuntimeError, 'Custom 404 response'    end  endendconn = Faraday.new('https://github.com/') do |c|  c.use CustomErrors  c.use Faraday::Adapter::NetHttpendresponse = conn.get '/cant-find-me' #=> `on_complete': Custom 404 response (RuntimeError)

For your code, you'll probably want to put it in a separate file, require it, modularise it etc.

If you want to see a good live example, the new Instagram gem has a pretty good setup to raise custom errors: GitHub link
