What is @braintree/sanitize-url?
The @braintree/sanitize-url npm package is designed to help developers ensure that URLs are safe for use within their applications. It provides functionality to sanitize URLs, removing potentially malicious or harmful content. This can be particularly useful in preventing XSS (Cross-Site Scripting) attacks by ensuring that only safe and valid URLs are allowed.
Sanitize URLs
This feature allows you to sanitize a URL, ensuring it is safe to use. If the URL contains potentially harmful JavaScript or other malicious content, it is replaced with 'about:blank', indicating that the original URL was not safe. This is particularly useful for preventing XSS attacks.
"use strict";
const sanitizeUrl = require('@braintree/sanitize-url').sanitizeUrl;
let safeUrl = sanitizeUrl('javascript:alert(document.cookie)');
console.log(safeUrl); // 'about:blank'
safeUrl = sanitizeUrl('https://www.example.com');
console.log(safeUrl); // 'https://www.example.com'
