Email Validation

This feature allows you to validate whether a string is a valid email address.

import validator from 'validator';

const email = 'test@example.com';
const isValidEmail = validator.isEmail(email);
console.log(isValidEmail); // true or false

URL Validation

This feature enables you to check if a string is a valid URL.

import validator from 'validator';

const url = 'https://www.example.com';
const isValidUrl = validator.isURL(url);
console.log(isValidUrl); // true or false

Sanitize Data

This feature allows you to sanitize input to prevent XSS attacks by escaping HTML characters.

import validator from 'validator';

const dirtyString = '<script>Alert('XSS')</script>'; 
const cleanString = validator.escape(dirtyString);
console.log(cleanString); // '&lt;script&gt;Alert(&#x27;XSS&#x27;)&lt;/script&gt;'
