Global rescue and logging exceptions in Sinatra

How do I specify a global rescue in case of an exception, and if you use Sinatra for an API or application, how do you handle logging?

Solution

  • 404s can be handled with the help of the not_found method like eg:

    not_found do
  'Site does not exist.'
end

    500s can be handled by calling the error method with a block, eg:

    error do
  "Application error. Pls try later."
end

    The details of the error can be accessed via the sinatra.error in request.env like so:

    error do
  'An error occured: ' + request.env['sinatra.error'].message
end
