Join the AI Workshop to learn more about AI and how it can be applied to web development. Next cohort February 1st, 2026

The AI-first Web Development BOOTCAMP cohort starts February 24th, 2026. 10 weeks of intensive training and hands-on projects.

Node.js is excellent for building command-line tools. From simple scripts to complex CLI applications, Node.js provides everything you need to create powerful terminal-based programs.

In this unit, you’ll learn to build command-line tools with Node.js. We’ll cover parsing command-line arguments, reading user input, spawning child processes to run other programs, handling process signals, and managing program execution flow.

These skills enable you to create your own CLI tools for automation, build systems, development utilities, and any other task that benefits from terminal-based interaction.
