A simple To-Do List application built with Node.js, TypeScript, and MongoDB. This app supports basic CRUD operations to manage tasks.

• Add New Tasks: Create tasks with a title and description.
• View Tasks: Retrieve a list of all tasks.
• Edit Tasks: Update task details or mark them as completed.
• Delete Tasks: Remove tasks when no longer needed.

Ensure you have the following installed:

• Node.js (v16+ recommended)
• MongoDB (running locally or using MongoDB Atlas)
• A code editor (e.g., VS Code)

• Node.js: JavaScript runtime for server-side development.
• TypeScript: Superset of JavaScript with static typing.
• MongoDB: Database for storing tasks.
• Express: Framework for building APIs.
• Mongoose: ODM library for MongoDB.
• dotenv: Environment variable management.

Follow these steps to set up and run the project:

1. Clone the Repository

   git clone https://github.com/your-username/todo-list-app.git
   cd todo-list-app

2. Install dependencies npm install
3. Setup environment variables Create a .env file in the project root and add: MONGO_URI=mongodb://localhost:27017/todolist PORT=5005
4. Run the application npm run dev (In development phase) npm start (in production)
5. Access the API http://localhost:5005/api/tasks

API Endpoints Base URL bash Copy code http://localhost:5005/api/tasks Method Endpoint Description GET / Retrieve all tasks. POST / Create a new task. PUT /:id Update a task by ID. DELETE /:id Delete a task by ID.

Example Task Object { "_id": "6751a74aa065ed34070d088d", "title": "Sample Task", "description": "This is a sample task.", "completed": false }

Scripts npm run dev: Run the app in development mode (hot reloading). npm start: Run the app in production mode. npm run build: Compile TypeScript to JavaScript.

Future Enhancements User authentication and authorization. Due dates and priority levels for tasks. Frontend interface using React or Angular. Deployment to a cloud platform (e.g., AWS, Heroku)
