## What it is
A JavaScript library for sanitizing untrusted HTML to prevent XSS attacks using a configurable whitelist of allowed tags and attributes. It works in Node.js and browsers and supports custom filtering functions.

## Use cases
- sanitize user-submitted HTML comments
- prevent XSS attacks in web apps
- filter HTML input with a whitelist
- strip script tags from rich text
- clean untrusted HTML before rendering

## When to choose
- you need whitelist-based HTML sanitization in Node.js or the browser
- you want fast, battle-tested XSS filtering with custom tag/attribute handling

## When to avoid
- you need to sanitize non-HTML content like Markdown or CSS
- you need a full DOM parser or HTML rewriting beyond filtering

## Facets
- artifact type: library
- maturity: stable
- function: security, serialization, web-framework
- domain: security, web-development, backend
- platform: browser
- tags: xss, html-sanitizer, whitelist, input-filtering, npm, nodejs, javascript
