🚀 Project Setup

Backend Setup

1. Clone the backend repository:

   git clone https://github.com/dushkin/My-Notes-and-Tasks-Backend.git
   cd My-Notes-and-Tasks-Backend

2. Install backend dependencies:

   npm install

3. Create an environment file: Create a .env file in the backend directory and add the following required variables:

   # The connection string for your MongoDB database
   MONGODB_URI=mongodb://localhost:27017/MyNotesAppDB
   
   # A strong, secret string for signing JWTs
   JWT_SECRET=your_super_secret_jwt_key
   
   # The port for the backend server to run on
   PORT=5001
   
   # Comma-separated list of allowed origins for CORS
   ALLOWED_ORIGINS=http://localhost:5173
   
   # (Optional) Set the lifetime for tokens
   # JWT_EXPIRES_IN=15m
   # REFRESH_TOKEN_EXPIRES_IN=7d

Frontend Setup

1. Clone the frontend repository:

   git clone https://github.com/dushkin/My-Notes-and-Tasks.git
   cd My-Notes-and-Tasks

2. Install frontend dependencies:

   npm install

3. (Optional) Frontend Environment File: If your frontend needs to connect to a backend not on http://localhost:5001, create a .env file in the frontend root and add:

   VITE_API_BASE_URL=http://your-backend-url/api

---

🎯 Running the Application

You need to run both the backend and frontend servers in separate terminals.

1. Start the backend server: From the My-Notes-and-Tasks-Backend directory:

   npm run dev

   The API server will start on the port defined in your .env file (e.g., 5001).

2. Start the frontend server: From the My-Notes-and-Tasks directory:

   npm run dev

   The application will be available at http://localhost:5173.

📚 API Documentation

The backend includes comprehensive API documentation generated with Swagger. Once the backend server is running, you can view the interactive API documentation at:

http://localhost:5001/api-docs

Additionally, a Postman collection is available in the backend repository for easy API testing.
