Why Do We Even Deploy? (A Funny Guide to Putting Your NestJS Baby Online) 🚀

So you built a NestJS app. It runs beautifully on http://localhost:3000.

You show it to your mom:

“Look ma, I made an API!”

She replies:

“Beta, I can’t see it on my phone.”

And that, my friend, is when you realize:

Localhost is not the world. 🌍

🧐 What Does “Deploy” Even Mean?

Deployment is basically:

Taking your app from your laptop (where only you can see it)…
Putting it on a server (where your crush, boss, client, or even dog can see it). 🐶

Think of it like this:

Localhost → Your secret diary.
Deployment → Publishing that diary online so everyone can read your embarrassing 7th grade poetry.

Short answer: Anyone with WiFi and some patience.

Longer (funnier) answer:

Developers → Obviously, we love to show off.
Non-techies → Yes, even your uncle who thinks “NestJS” is a bird sanctuary.
Freelancers → Because saying “Deployed to Production” on your invoice sounds way cooler than “Ran on my laptop.”
Students → Professors love deployed projects. (Also, brownie points.) 🍪
Hackers → They deploy too, but… let’s not talk about that. 🙈

But for now, just remember:

🚀 Deploying is how you go from “Look ma, it works!” to “Look ma, it’s on the internet!”
