After 47 years of mass-producing bugs, I’ve discovered that what people call “dependency hell” is actually just dependency heaven with poor marketing. Let me enlighten you.

The More Dependencies, The Merrier

You know what’s lonely? Writing code yourself. You know what’s a party? Having 2,847 packages in your node_modules, each written by a stranger on the internet.

$ du -sh node_modules/
1.8G    node_modules/

$ find node_modules -type f | wc -l
147892

# That's not bloat. That's COMMUNITY.

Every one of those packages is a friend you haven’t met yet. A friend who might abandon their project at any moment, but still. Friends.

The is-odd Philosophy

People mock packages like is-odd and is-even. But think about it: do YOU want to spend 3 seconds writing n % 2 === 1? That’s 3 seconds you could spend adding MORE dependencies.

// AMATEUR: Writing your own code like a peasant
const isOdd = n => n % 2 === 1;

// PROFESSIONAL: Standing on the shoulders of giants
const isOdd = require('is-odd');
const isEven = require('is-even');
const isNumber = require('is-number');
const isString = require('is-string');
const isArray = require('is-array');
const isFunction = require('is-function');
const isNotAFish = require('is-not-a-fish'); // You never know

As XKCD 2347 brilliantly illustrates, modern infrastructure depends on a project maintained by one random person in Nebraska. That’s not a bug. That’s efficient resource allocation.

A Beautiful Comparison

Version Pinning Is For Control Freaks

Some developers “pin” their dependency versions. "lodash": "4.17.21" — how boring. Where’s the excitement? Where’s the adventure?

{
  "dependencies": {
    "lodash": "*",
    "react": "latest",
    "mystery-package": ">=0.0.1",
    "totally-safe-lib": "git://github.com/randomuser123/who-knows"
  }
}

Every npm install is like opening a present. Will your build work today? Who knows! That’s called excitement-driven development.

The PHB Wisdom

“We need to reduce our dependency footprint.” “Why? Each dependency is someone else’s code we don’t have to maintain.” “…Promoted.” — Pointy-Haired Boss, Dilbert

The PHB understands economics. Why pay developers to write code when you can download it for free from npm? Each dependency is outsourced labor with zero paperwork.

Transitive Dependencies: The Gift That Keeps Giving

Your direct dependencies are just the beginning. Each of THOSE has dependencies. It’s dependencies all the way down. Like Russian nesting dolls, but they all have different versions of minimist.

your-app (1 direct dependency)
└── express (57 dependencies)
    └── body-parser (10 dependencies)
        └── raw-body (3 dependencies)
            └── unpipe (0 dependencies, but spiritually infinite)

This is called job security. No one can replace you when only you understand the dependency graph.

Left-Pad: A Love Story

Remember when left-pad was removed from npm and broke the internet? Beautiful. That’s not a cautionary tale. That’s proof of how much we loved it. We loved it so much we couldn’t function without it.

// 11 lines that kept the world spinning
function leftPad(str, len, ch) {
    str = String(str);
    ch = String(ch || ' ');
    let i = -1;
    len = len - str.length;
    while (++i < len) {
        str = ch + str;
    }
    return str;
}
// Poetry. Art. Someone else's problem.

Supply Chain Attacks Are Just Surprise Features

Sometimes a dependency maintainer sells their package to someone who adds malicious code. That’s not a vulnerability. That’s user acquisition. Your app now has more features! Mining cryptocurrency, exfiltrating data, joining botnets — all free of charge.

The node_modules Black Hole

Scientists say nothing escapes a black hole. The same is true of node_modules. Once a package enters, it never truly leaves. You can npm uninstall all you want, but the phantom dependencies remain in your heart.

$ rm -rf node_modules
$ npm install
$ du -sh node_modules/
2.1G    node_modules/

# It's bigger now. It feeds on deletion attempts.

Embrace The Chaos

Stop trying to audit your dependencies. Stop running npm audit. Stop checking if that package with 12 weekly downloads is trustworthy. Trust everyone. The npm ecosystem is like a potluck — you wouldn’t ask your neighbors what’s in their mystery casserole, would you?

Conclusion

Dependency hell is just a hug from thousands of strangers who wrote code so you don’t have to. Is your node_modules folder 3GB? Congratulations, you’re popular. Do you have 47 versions of the same package? That’s diversity.

Stop fighting it. Install another package. Let the dependencies flow through you.

npm install everything-in-the-world

The author’s laptop ran out of disk space in 2019. node_modules consumed the rest. He is at peace.
