Sinatra access-control-allow-origin for sinatra public folder

Question

How do I set up Sinatra so that static files in the public folder are returned with the response Access-Control-Allow-Origin = \"*\" ?

Answer 1

this solution works for me and is based on an answer on a similar question How to add "Access-Control-Allow-Origin" headers to API Response in Ruby

get '/' do
  response['Access-Control-Allow-Origin'] = '*'
  "asdf"  # return "asdf" 
end
