WorkerDOM is a TypeScript implementation of the DOM API designed to run inside a Web Worker, syncing only necessary DOM mutations to the main thread. It lets frameworks and DOM code execute off the main thread while rendering to the page.

Use cases

• run DOM manipulation in a web worker to keep the main thread free
• sandbox third-party embedded content alongside first-party code
• reduce expensive rendering jank for non-synchronous UI updates
• build interactive widgets without blocking user input
• power amp-script style safe embedded scripting

When to choose

• your page suffers main-thread contention from DOM-heavy code
• you need to isolate third-party scripts embedded in your document
• you want framework-agnostic DOM APIs executed off-thread

When to avoid

• your app needs synchronous DOM reads/writes with immediate layout feedback
• you target very old browsers without Web Worker support
• you need full compatibility with every DOM API or browser extension
