@types/sanitize-html

What is @types/sanitize-html?

@types/sanitize-html provides TypeScript type definitions for the sanitize-html library, which is used to sanitize HTML input by removing potentially dangerous elements and attributes.

What are @types/sanitize-html's main functionalities?

Basic HTML Sanitization

This feature allows you to sanitize a string of HTML by removing any potentially dangerous elements like <script> tags.

const sanitizeHtml = require('sanitize-html');
const dirty = '<script>alert("xss")</script><div>Safe content</div>';
const clean = sanitizeHtml(dirty);
console.log(clean); // Output: <div>Safe content</div>

Customizing Allowed Tags and Attributes

This feature allows you to specify which HTML tags and attributes are allowed in the sanitized output.

const sanitizeHtml = require('sanitize-html');
const dirty = '<a href="http://example.com" onclick="stealCookies()">Click me</a>';
const clean = sanitizeHtml(dirty, {
  allowedTags: [ 'a' ],
  allowedAttributes: {
    'a': [ 'href' ]
  }
});
console.log(clean); // Output: <a href="http://example.com">Click me</a>

Transforming Tags

This feature allows you to transform specific tags in the HTML input, such as changing the src attribute of img tags.

const sanitizeHtml = require('sanitize-html');
const dirty = '<img src="http://example.com/image.jpg" />';
const clean = sanitizeHtml(dirty, {
  transformTags: {
    'img': sanitizeHtml.simpleTransform('img', { 'src': 'https://example.com/placeholder.jpg' })
  }
});
console.log(clean); // Output: <img src="https://example.com/placeholder.jpg">
