Ok, so there is one downside to webapp dev on an ipad…

puts.js

app.puts = (...anything) => {          
  fetch("/api/puts", {                                                   
    method: 'POST',                                      
    headers: {                                                                     
      'Content-Type': 'application/json'              
    },
    body: JSON.stringify({content: anything})
  })
} 

puts_controller.rb

module Api
  class PutsController < ApiController
    def create
      puts <<~TEXT
        Client logger says:
      
        #{params[:content].map(&:to_json).join(", ")}
      
      TEXT
    end
  end
end
