BUILDING CLI TOOLS WITH NODEJS
summary
Claims that a full CLI slide deck runs on core Node only and actually works: a terminal‑in‑terminal that is responsive and watches files, built with process.stdout.write for cursor control, readline for key events, child_process exec/spawn for commands (exec buffers output until completion; spawn streams in real time), fs sync where needed, ANSI color codes, and packaged via npm link/npm publish with a shebang and bin mapping. Argument parsing proves surprisingly hairy (32 lines) and command‑injection is a real risk.
