Build a Simple GET API in Express (No Database Needed) | Get All Hotels from JSON File | Part #60

🚀 Introduction:
Ready to build your first real endpoint? In this lecture, we move from theory to action by creating a GET API endpoint to fetch hotel data.

To keep things simple for beginners, we won't use a complex database yet. Instead, we’ll use Node.js’s built-in fs (File System) module to read data directly from a JSON file and serve it to the client. This is the perfect way to understand the "plumbing" of an API before we introduce MongoDB.

🤔 What you will learn in this video?
✔️ How to set up a GET route in Express.js.
✔️ Using the fs.readFile and fs.readFileSync methods.
✔️ Why we must JSON.parse() data before sending it.
✔️ The magic of res.json(): Sending professional API responses.
✔️ Understanding the Request-Response cycle with real file data.
✔️ The Reality Check: Why file-based storage is great for learning but limited for real-world apps.
✔️ When and why we eventually need to move to a real Database (MongoDB).

This video is a core building block for any aspiring Backend or MERN stack developer. Let's get coding!
