📌 About This Project

This is a simple, yet complete CRUD (Create, Read, Update, Delete) API written entirely in JavaScript using Node.js and Express.js.

🔧 In this project:

• Users can sign up, log in, and receive tokens
• Each user manages a task list through standard CRUD operations
• Data is stored in a mock in-memory db structure (model.js)

---

💡 What is CRUD?

CRUD stands for:

• 🟢 Create → Add new data
• 🔵 Read → Fetch existing data
• 🟠 Update → Modify existing data
• 🔴 Delete → Remove data

These four operations are the backbone of nearly every application you use today.

🔑 API Endpoints

Method	Endpoint	Description
POST	/v1/api/signup	Register new user
POST	/v1/api/login	Login with username/password
GET	/v1/api/	Fetch user's task data
POST	/v1/api/	Add new task
PUT	/v1/api/	Update task by ID
DELETE	/v1/api/	Delete task by ID

🔐 All routes (except signup/login) require a valid token inside the request body to identify the user.

🚀 How to Run

# Clone the repo
git clone https://github.com/enavid/CRUD.git

# Move into the directory
cd CRUD

# Install dependencies
npm install express

# Start the server
node server.js

🌐 Server runs on: http://localhost:3000/v1/api

🧠 What I Learned

• Modular structure of Express apps
• RESTful API design
• Authentication with token (no external libraries)
• Data handling with mock databases
• Error handling and user-specific responses
