a simple middleware for you

import Check from 'eagle-validator';

export default function validator(req, res, next) {
  const valid = [
    new Check({ firstName: req }).str().req().min(2).max(20).alpha(),
    new Check({ phoneNumber: req }).str().req().min(2).num(),
    new Check({ email: req }).str().req().email(),
  ];
  const invalid = valid.find((e) => e.error);
