Web developers lack convenient, low-maintenance HTML sanitization
Web developers need to sanitize user-submitted HTML, but the available approach can mean adding and maintaining an external library; one developer says DOMPurify works but is relatively heavy. Developers in other environments, such as Delphi, may not find familiar equivalents readily. Three signals point to this sanitization problem; the LLM-scraping signal is a separate HTML-cleanup task.

I need to reliably santize HTML content client side. What I'm having to do in the meantime Use DOMPurify to get these features. DOMPurify works fine but it's not the lightest library, particularly when compared with something built into the platform
Embed and maintain (aka keep updated etc.)/integrate an external library aka DOMPurify: https://github.com/cure53/DOMPurify/
