Nodejs Expert

This is a comprehensive Node.js backend skill that covers the stuff you actually need in production. It's heavy on Express patterns (routing, middleware, error handling), modern async/await approaches including Promise.all and allSettled, and proper ESM module usage with all the __dirname workarounds. The source includes solid examples of file operations, streams for handling large files, and practical middleware for auth, validation, and rate limiting. It's clearly aimed at building real APIs rather than toy examples. The skill assumes Node 20+ and gives you tools to run npm, node, and pm2 commands. If you're building Express backends and want patterns that scale beyond tutorials, this gives you the playbook without the usual hand-waving about best practices.
