54 CLI Tools I Built with Node.js — Sorted by Usefulness

54 CLI Tools I Built with Node.js — Sorted by Usefulness I built 54 command-line tools with Node.js over the past year. Some solve real problems I hit daily. Others were 2 AM rabbit holes I never returned to. Here they are, ranked honestly from "I'd be lost without this" to "I can't believe I spent four hours on that." Every tool is on npm. Every install command works. And I've tagged each one with the tier it actually deserves. Tier S — Must-Have (Top 5) These are the tools I actually use every single day. If my machine got wiped, these get reinstalled before VS Code. 1. envcheck-cli Validate .env files against .env.example — catch missing variables before production does. npm install -g @chengyixu/envcheck-cli envcheck --source .env --template .env.example # Missing: DATABASE_URL, REDIS_HOST # Extra: OLD_API_KEY (not in template) # Empty: SMTP_PASSWORD (defined but blank) I built this after deploying to staging with a missing STRIPE_SECRET_KEY and watching the checkout page throw 500
