abolish.addValidator(EmailValidator);

// Add Custom Validtor
abolish.addValidator({
  name: 'addProtocol',
  validator: (url, option, {modifier}) => {
    // Check if url does not have required protocol
    if (url.substring(0, option.length) !== option) {
      // Add protocol
      modifier.setThis(`${option}://${url}`)
    }
    return true

const form = {
  email: 'appdeveloper@sky.com',
  username: 'john_doe',
  age: 18,
  url: 'wildstream.ng'
};

const [error, validated] = abolish.validate(form, {
  $: 'required|typeOf:string', // $ or '*' is considered as wildcard
  email: 'isEmail',
  username: '*',
  age: 'typeOf:number|max:20',
  url: 'addProtocol:http'

console.log({form, validation: {error, validated}});
