Installation

1. Clone the repository

git clone https://github.com/yourusername/node-mongodb-rest-api.git

2. Install dependencies

npm install

3. Set up environment variables Create a .env file in the root directory with the following variables:

NODE_ENV=development
PORT=5000
MONGO_URI=your_mongodb_connection_string

Usage

Authentication

Most endpoints require authentication. To authenticate, obtain a token by logging in:

POST /api/users/login
{
  "email": "user@example.com",
  "password": "123456"
}

Then use the token in subsequent requests:

Authorization: Bearer your_token_here
