I built the most over-engineered utility library ever

Wed, 07 Jan 2026 20:33:28 +0000

TL;DR: I created LoLite, a JavaScript utility library that uses 67+ dependencies just to add two numbers, has over 380 passing tests, and over 90% code coverage. It's a parody of over-engineering, but it actually works!

What is LoLite?

LoLite is a "10x enterprise-grade" utility library that takes simple operations and makes them use as many npm package as possible. Want to add 2 + 2? Sure, but first we need to import 15 packages!

GitHub Repository

Features

✅ Full TypeScript Definitions
✅ 30+ utility functions (arrays, math, logic gates, validation)
✅ Comprehensive documentation (Code of Conduct, Contributing Guide, Security Policy)
✅ High test coverage (Over 90%)
✅ Extreme linting - ESLint with 3 plugins and almost all rules enabled

Some Examples

Adding Two Numbers

const lolite = require("lolite")
console.log(lolite.add(5, 2)) // 7, but with 10+ dependencies!

The Dependency Tree

When you run npm list --all, the output is over 10,000 lines! It includes:

Every number from 1-100 as individual packages (@positive-numbers/forty-two)
Every letter of the alphabet (@lowercase-letters/z)
Hundreds of emoji packages (emoji-poop, emoji-sunglasses)
Over 100 different is-wds packages from Web Dev Simplified viewers
Packages like nan-is-a-function@67.67.67

Please star the LoLite repository, and check out some of the source code!. You can also check out some other packages I've made like this one on the enterprise-npm-ai org.
