nodejs-development · manutej — Claude Code skill: Node.js without blocking

What nodejs-development does

The skill gives the agent a working picture of Node.js internals. Covered: the phases of the event loop, CommonJS versus ES modules, and built-in modules such as fs, path, http and crypto. A separate section walks through callbacks, promises and async/await, with Promise.all, Promise.race and Promise.allSettled shown side by side.

Blocking is treated as a first-class problem. fs.readFileSync halts the whole process, so the examples swap it for fs.promises.readFile, and CPU-heavy work moves into worker_threads. That matters on a hot path: left alone, an agent will happily keep the synchronous call.

One command installs it. The npx skills add line drops SKILL.md into the skills directory of whichever platform you pick. GitHub Copilot uses gh skill install instead. Node.js and npm are all you need to run the examples.
