Does it support the latest Deno features?

Yes, it specifically includes patterns for Deno v2.4+ features, including Explicit Resource Management (the 'using' keyword) and Symbol.dispose.

Can this skill help prevent memory leaks?

Absolutely. It promotes the use of the 'using' statement and proper scope-based cleanup, ensuring that timers, database connections, and file handles are disposed of even if an error occurs.

How does this skill help with Node.js migration?

It provides a clear reference and implementation logic to convert Node-specific modules like 'fs' and 'http' into Deno's native Web Standard implementations and built-in Deno APIs.

Why should I use async generators for polling instead of setInterval?

Async generators in Deno provide better control over timer drift, allow for immediate and clean cancellation by breaking the loop, and integrate more seamlessly with structured concurrency.

Learning & Documentation

Guides the implementation of modern TypeScript patterns and provides expert assistance for migrating Node.js applications to Deno using Web Standard APIs.

About

This skill optimizes your Deno development workflow by providing domain-specific guidance on modern JavaScript and TypeScript patterns, specifically focusing on Deno v2.x features. It streamlines the transition from Node.js by mapping legacy patterns to modern Deno equivalents, such as replacing manual cleanup with the 'using' statement for explicit resource management, swapping traditional polling for async generators, and utilizing type-safe Deno error classes. By prioritizing Web Standard APIs for HTTP, file operations, and cryptography, this skill ensures your codebase is performant, exception-safe, and aligned with Deno's core philosophy.
