Creating a Faraday middleware

I’ve been playing around with Faraday recently and wanted to make a middleware. The guide on the wiki leave a little to be desired. Googling didn’t seem to help much either. I eventually found a Faraday Middleware github repo that helped me.

Here is a sample middleware that I ended up using:

class MyMiddleware < Faraday::Middleware
  def call(env)
    env[:request_headers]["My-Custom-Header"] = "my-custom-value"

    @app.call(env)
  end
end

connection = Faraday.new("http://google.com/") do |faraday|
  faraday.use MyMiddleware
  faraday.adapter Faraday.default_adapter
end
