Complexity

This module is designed for the Strongloop Loopback framework. It allows of any Model to validate the complexity of a field. It can help to builds regular expressions based on common settings for passwords, username, and other user identification methods.

  npm install --save loopback-mixin-complexity

          "min": 6,          // minumum number of characters
          "max": 16,         // silly idea to have maximum...
          "exact": 20        // match the exact number of characters
        }
