How does it handle Node.js APIs like 'fs' or 'path'?

The skill identifies incompatible APIs and suggests edge-native alternatives, such as using Cloudflare R2 for storage instead of the local file system.

Does it support AWS Lambda migration?

Absolutely. It includes a handler conversion guide to translate standard AWS Lambda event/context patterns into the Workers Fetch API format.

Can this skill help migrate from Express.js?

Yes, it provides specific patterns for converting Express middleware and routes to Workers-compatible frameworks like Hono, ensuring a similar developer experience on the edge.

What are the most common migration errors it solves?

It specifically addresses issues like 'fs is not defined', 'Buffer' globals, environment variable access differences, and ESM vs. CommonJS module requirements.
