Multiform-validator

This npm package provides JavaScript functions to validate various forms fields.

If you want to help me, you can buy me a coffee (:

INFO:
All functions that have the name "validate" return an object with two properties, isValid: true | false and errorMsg: 'String with errors'
The remaining ones can return true|false|string|array, look at the doc for each one

Feel free to find bugs and report them to me. Your feedback is highly appreciated. Hugs from Gabriel Logan!
