Usage

After installing the package, you can import and use the validateEmail and validatePassword functions in your project.

Email Validation

The validateEmail function checks if an email is in a valid format. It returns true for a valid email and false for an invalid email.

const { validateEmail } = require('validator-sameer');

const email = '[email protected]';

if (validateEmail(email)) {
  console.log('Email is valid');
} else {
  console.log('Email is not valid');
}

Password Validation

The validatePassword function validates a password based on the following customizable criteria:

• password (string): The password to validate.
• noOfChar (number): Minimum number of characters the password should have.
• specialCharAllowed (boolean): Whether special characters are required.
• numbersAllowed (boolean): Whether numbers are required.

const { validatePassword } = require('validator-sameer');

const password = 'Sameer@123';

if (validatePassword(password, 8, true, true)) {
  console.log('Password is valid');
} else {
  console.log('Password is not valid');
}
