  I like Pizza Message Syntax Validator.


  This is a custom message syntax validator
  it must throw a SyntaxError (or any Error) when a message has
  invalid syntax.

  You can even import a 3rd party library to validate the syntax. 
  Feel free to make a Pull Request also :)

    throw new SyntaxError('PIZZA word must prepended to each message. E.g, PIZZA message');
