Building a CLI Tool with Node.js in 2026: From Zero to npm Publish

I built 5 CLI tools last year. Here's the exact setup I use every time.

Why Node.js for CLIs?

One language for your whole stack (frontend + backend + CLI)

npm ecosystem — thousands of packages to leverage

Cross-platform — works on Mac, Linux, Windows

Fast enough — V8 is fast, startup time is acceptable

Familiar — if you know JS/TS, you can build CLIs

The Setup

mkdir my-cli && cd my-cli npm init -y

# Core dependencies (my go-to stack): npm install commander inquirer chalk ora figlet update-notifier npm install -D typescript @types/node tsx esbuild

Enter fullscreen mode

Exit fullscreen mode

Package Purpose

commander Argument parsing, subcommands

inquirer Interactive prompts

chalk Terminal colors

ora Spinners/loading indicators

figlet ASCII art banners

update-notifier Notify users of updates
