// WARNING in ./node_modules/ws/lib/validation.js
// Module not found: Error: Can't resolve 'utf-8-validate' in '/Users/dantup/Dev/Dart-Code/node_modules/ws/lib'
//
// These are caused by ws require()ing those two modules and they're not listed
// in our dependencies. Info on the reason for this is here:

// It appears to be safe to ignore these as they're being loaded in a try{} block
// and are optional.
