Does this skill support SharedArrayBuffer?

Yes, it includes guidance on detecting cross-origin isolated environments and safely utilizing shared memory when available.

What is the main benefit of using this skill?

It prevents main-thread blocking by moving heavy computations to background threads, ensuring smooth UI performance and high frame rates.

Can I use DOM or Three.js APIs inside a worker?

No, workers do not have access to the DOM or main-thread APIs. This skill helps you isolate pure math and data processing to be handled by workers, returning results to the main thread.

How does it handle worker failures?

The skill provides patterns for catching worker crashes, logging errors, and degrading gracefully to a main-thread fallback to prevent application failure.

Game Development

Optimizes application performance by offloading CPU-intensive computations to worker threads while maintaining main-thread responsiveness.

About

This skill provides comprehensive guidance for implementing and managing multithreaded environments in JavaScript and TypeScript applications. It focuses on offloading heavy mathematical calculations, physics simulations, or data processing to Web Workers or Node.js worker pools. By enforcing best practices such as structured cloning, transferable objects, and proper synchronization, the skill helps developers prevent UI blocking and main-thread lag in high-performance applications like 3D games or data-heavy dashboards.
