Sinatra logging for human beings.

It allows to set both Rack, error and application logger.

It uses Rack::Commonlogger under the hood so the logger has to respond to:

• <<(message)
• puts(message)
• flush

Add this line to your application's Gemfile:

gem "sinatra-sane-logging", require: "sinatra/sane_logging"

And then execute:

$ bundle

Or install it yourself as:

$ gem install sinatra-sane-logging

require "logger"
require "sinatra/base"
require "sinatra/sane_logging"

class FileLogger < Logger
  def flush; end
end

class App < Sinatra::Base
  register Sinatra::SaneLogging

  sane_logging logger: Filelogger.new(File.open("log/app.log", "a+").tap { |log_file| log_file.sync = true })

  get "/" do
    logger.info "OK"

    "OK"
  end
end
