Modern Backend Development Training – Fetch Single & All Record API

Welcome to Part 19 of the Modern Backend Development Training series! In this session, we implement the GET APIs to fetch all records and a single record by ID from MongoDB using Express and Mongoose.

These endpoints are essential to nearly every application—allowing users and services to access stored data quickly, efficiently, and securely.

✅ What You’ll Learn in This Video:
✔️ Creating GET routes to fetch all documents (e.g., /api/tasks)
✔️ Creating GET routes to fetch a single document by ID (e.g., /api/tasks/:id)
✔️ Using Mongoose methods like .find() and .findById()
✔️ Handling errors: invalid IDs, not found responses, and server issues
✔️ Testing both endpoints using Postman

💡 Why This Step Matters:
🔹 Powers data display in your frontend UI
🔹 Teaches RESTful patterns for data retrieval
🔹 Reinforces database querying and response shaping
🔹 Establishes secure and scalable access to stored records
