When you're developing web apps, you often hear about “running a local server”.
A local server is basically your computer acting like a real web server, but only for you. Instead of deploying your app online, you run it on your machine using tools like Node.js, Spring Boot, or Go.
It usually runs on something like:
http://localhost:3000 or http://localhost:8080
How it works:
- Your app starts a server on your computer
- It listens for requests (like a browser opening a page)
- It sends back responses (HTML, JSON, etc.)
- Everything happens locally without the internet
Why it’s useful:
- Fast development (no deployment needed)
- Safe testing environment
- Easy debugging
- You can simulate real backend behavior
In short: a local server is your personal playground for building and testing web apps before going live 🚀
