validate email javascript

To validate an email address in JavaScript using Node.js, you can follow these steps:

1. Import the built-in email-validator module:

const validator = require('email-validator');

This step imports the email-validator module, which provides a set of functions to validate email addresses.

1. Use the validator.validate() function to check if the email is valid:

const isValidEmail = validator.validate('[email protected]');

In this step, you pass the email address you want to validate as an argument to the validate() function. The function returns a boolean value indicating whether the email address is valid or not.

1. Check the value returned by the validate() function:

if (isValidEmail) {
  // Email is valid
} else {
  // Email is invalid
}

Based on the value returned by the validate() function, you can perform different actions or validations. If the email is valid, you can proceed with further processing or display a success message. If the email is invalid, you can display an error message or prompt the user to enter a valid email address.

Here is the complete code example:

const validator = require('email-validator');

const email = '[email protected]';
const isValidEmail = validator.validate(email);

if (isValidEmail) {
  console.log('Email is valid');
} else {
  console.log('Email is invalid');
}

This code imports the email-validator module, validates the email address provided, and logs a message indicating whether the email is valid or not. You can replace '[email protected]' with the email address you want to validate.

By following these steps, you can use the email-validator module in Node.js to validate email addresses.
