A simple function that generates the RegExp expression for passwords validation.

npm install password-regexp

const passwordRegexp = require("password-regexp")();

passwordRegexp.test("abc123"); // returns false

passwordRegexp.test("Strong12"); // returns true

⚠️ Please, don't forget to use parentheses after the "require" statement!

By default, it generates a RegExp, that check a string value that match:

• at least, 1 numeric character
• at least, 1 uppercase letter
• at least, 1 lowercase letter
• min 8, max 32 symbols.

These conditions are customizable by function atrributes:

const passwordRegexp = require("password-regexp");

const customRegexp = passwordRegexp({
  min: 12,
  max: 18,
  numeric: false,
  uppercase: false,
  symbols: true, // an option for symbols: ! @ # $ % ^ &
});
