We’ve all seen the meme: a black hole, a highway collapsing, or the universe warping under the unimaginable weight of a single folder named node_modules.
It used to be a joke. Today, it’s a production hazard.
If you create a fresh project using some modern meta-frameworks or tools, before you even write your first console.log(), you already have tens of thousands of files sitting in your directory. We have reached a point where we need thousands of external packages just to render text on a screen or route a basic HTTP request.
How did the JavaScript ecosystem become so heavily dependent on others, and why is this breaking modern software engineering?
The "Left-Pad" Trauma and the Security Nightmare
A few years ago, the internet famously broke because a developer unpublished a tiny 11-line package called left-pad. Today, the problem is much worse, but it’s silent. It hides under the name of Supply Chain Attacks.
When you install a major framework, you aren't just trusting that framework. You are trusting the hundreds of anonymous open-source developers who wrote the micro-dependencies that the framework relies on.
Every time you run npm install, you are playing roulette with:
- Malicious packages disguised as typos.
- Deprecated code running in your production environment.
- The infamous
Found 87 vulnerabilities (12 critical)message that nobody actually knows how to completely clear.
The Art of "No-Dependency" Coding
A silent revolution is happening. Senior developers are actively looking at their package.json and asking: "Can I write this myself in 10 lines of code instead of installing a 5MB package?"
Modern runtimes like Node.js (with its native test runners and .env support), Bun, and Deno are trying to cure this sickness by built-in tools that eliminate the need for basic third-party utilities.
Look at our backend stacks:
- Do you really need a massive utility library just to capitalize a string or filter an array? No, native JavaScript array methods are incredibly fast now.
- Do you need a dependency to format a date? Often, the native
Intl.DateTimeFormatAPI does exactly what you want.
Keeping your code close to the metal (or native to the runtime) makes your application faster, secure, and infinitely easier to upgrade.
Finding the Sweet Spot
Don't get me wrong. I am not saying you should build your own ORM instead of using Prisma, or rewrite Fastify from scratch. Frameworks and complex tools solve massive, hard problems, and they deserve to be in your project.
The problem is the micro-dependency addiction. Installing an entire package just to check if a number is even (yes, is-even is a real package with millions of downloads) isn't smart engineering—it's laziness.
The next time you are tempted to run npm install <package>, take 2 minutes to think: Can I write a simple, typed function to handle this? Your deployment speed, your security team, and your laptop's hard drive will thank you.
Time to confess...
What is the most ridiculous, tiny package you have ever found buried deep inside your node_modules? Are we too lazy to write plain JavaScript/TypeScript nowadays?
