Day 34 of #100DaysOfCode — Creating a Database CRUD API

Today, for Day 34 of #100DaysOfCode , the goal was to build a database api that saves the data in the MongoDB database using Mongoose schema and Node.js and Express.js routes. TL;DR The CRUD REST API was built using: Node.js Express MongoDB Mongoose This project implements the four essential backend operations: Create Read Update Delete Project Folder Structure To keep the code organized, I used a separation-of-concerns structure. project/ │ ├── models/ │ └── Todo.js │ ├── routes/ │ └── todoRoutes.js │ ├── controllers/ │ └── todoController.js │ ├── config/ │ └── db.js │ ├── server.js ├── .env └── package.json This structure separates responsibilities: Folder Responsibility Models Database schema Routes API endpoints Controllers Business logic Config Database connection Server Application entry point This pattern scales well for larger APIs and production apps . Step 1 — Initialize the Project Create a new Node project: npm init -y Install required dependencies: npm install express mong
