Task Manager Application

This is a Task Manager Application built using Node.js, Express.js, and MongoDB. The application allows users to perform CRUD (Create, Read, Update, Delete) operations on tasks. It is structured as a RESTful API with endpoints for managing tasks.

---

Features

• Add new tasks.
• Retrieve all tasks or a specific task by ID.
• Update existing tasks.
• Delete tasks.
• Serve static files for the frontend.

API Endpoints

Base URL: /api/v1/tasks

Method	Endpoint	Description
GET	/	Fetch all tasks
POST	/	Create a new task
GET	/:id	Fetch a single task by ID
PATCH	/:id	Update a task by ID
DELETE	/:id	Delete a task by ID

---

Technologies Used

• Node.js: JavaScript runtime for building server-side applications.
• Express.js: Web framework for creating RESTful APIs.
• MongoDB: NoSQL database for storing task data.
• Mongoose: ODM library for MongoDB.

How It Works

Backend Logic

1. Database Connection:

   • The connectDB function in connect.js establishes a connection to MongoDB using Mongoose.

2. Schema Definition:

   • The TaskSchema in schema.js defines the structure of each task document, including validation rules.

3. Controllers:

   • The task.js file contains functions to handle CRUD operations (e.g., getAllTasks, createTask, etc.).

4. Routes:

   • The routes/task.js file maps HTTP methods and endpoints to controller functions.

5. Middleware:

   • Static files are served using app.use(express.static('./public')).
   • JSON parsing is enabled with app.use(express.json()).

Frontend Logic

The frontend files are located in the public folder and include HTML, CSS, and JavaScript files for interacting with the API.

---

Running the Application

The application runs on two ports:

1. Port 3000: For serving the backend API.
2. Port 4000: For additional server functionality (if needed).

To start the application, use:

npm start

You should see logs indicating that the server is running on both ports.

Future Enhancements

• Add user authentication and authorization.
• Implement pagination for fetching tasks.
• Enhance frontend design and interactivity.
