Building Interactive npm Command Line Modules
summary
Node is practical for real CLIs: the talk shows a working npm module patterned from Unix ideas — filter, sink, source, ed, roguelike, spooler (daemon) — and walks through concrete tooling: argument parsing with yargs, prompts with prompt and inquirer, fullscreen UI with blessed/react-blessed. Examples include commands "run" and "config", aliases, defaults, help/usage syntax, and when to prefer scripting versus interactive input. The claim is actionable: buildable modules that parse args, prompt for choices, or render full-screen interfaces, and each approach is shown with code that actually runs.
