This project is a barter trading system that allows users to trade items with each other. It includes features for user authentication, item management, trade creation, and more.

• User Authentication: Register, login, and manage user profiles.
• Item Management: Create, update, and delete items for trade.
• Trade Creation: Propose trades between users with offered and requested items.
• Trade Status Updates: Accept or reject trades, which updates the status of the items involved.
• Messaging: Users can send messages within a trade to communicate.

The project includes comprehensive tests to ensure functionality and reliability.

To run the tests, use the following command:

npm test

To run the tests serially (recommended to avoid race conditions), use:

npm test -- --runInBand

• Node.js: Backend runtime environment.
• Express.js: Web framework for building the API.
• MongoDB: Database for storing user and item data.
• Mongoose: ODM for MongoDB.
• Jest: Testing framework for unit and integration tests.
• Cypress: End-to-end testing framework.

1. Clone the repository.
2. Install dependencies:

   npm install

3. Set up your environment variables (e.g., MONGODB_URI).
4. Run the application:

   npm run dev

5. Run the tests:

   npm test

• Docker installed on your system
• Docker Compose (optional, for easier management)

First, create a Docker network for container communication:

docker network create my-network

Start the MongoDB container:

docker run --network my-network \
  -p 27017:27017 \
  --name mongodb \
  mongo

Verify MongoDB is running:

docker ps | grep mongodb

Build the Docker image for the application:

docker build -t thenusan/barter-trading-system .

Run the application container with MongoDB connection:

docker run -p 3000:3000 \
  --network my-network \
  -e MONGODB_URI=mongodb://mongodb:27017/barter-trading \
  thenusan/barter-trading-system

1. Check if MongoDB is accessible:

docker exec -it mongodb mongosh --eval "db.runCommand({ ping: 1 })"

2. Access the application in your browser:

http://localhost:3000

1. Check MongoDB container status:

docker ps | grep mongodb

2. Check network connectivity:

docker network inspect my-network

3. Verify MongoDB logs:

docker logs mongodb

1. Check application logs:

docker logs <container_id>

2. Verify environment variables:

docker exec -it <container_id> env | grep MONGODB_URI

When you're done, you can clean up the containers and network:

# Stop containers
docker stop mongodb
docker stop <app_container_id>

# Remove containers
docker rm mongodb
docker rm <app_container_id>

# Remove network
docker network rm my-network

# Remove image
docker rmi thenusan/barter-trading-system
