better_errors

Better error page for Rack apps. Available at: https://github.com/charliesome/better_errors

The error codes generated when something went wrong with the Ruby code contains valuable information. However, they are often covered in a large number of lines and hides the most valuable information. Better_Errors make it easier for developers to find their issues by decoding the cryptic error message in a user friendly way.

Just pop this in your Gemfile

group :development do
  gem "better_errors"
end

and this in your app.rb to get much nicer errors

require "better_errors" if development?

configure :development do
  use BetterErrors::Middleware
  BetterErrors.application_root = __dir__
end

P.S. You’ll need to stop and start your server for it to work.
