• Stripe

• User Service: Handles user registration & authentication.
• Product Service: Manages product listings, categories, and inventory.
• Shopping Cart Service: Manages users’ shopping carts, including adding/removing items and updating quantities.
• Order Service: Processes orders, including placing orders, tracking order status, and managing order history.
• Payment Service: Handles payment processing, integrating with Stripe payment gateway.
• Notification Service: Sends email and SMS notifications using NodeMailer and Twilio.

• Microservices Architecture: Each service is a separate codebase, with its own database.
• API Gateway & Load Balancing: Nginx is used as an API gateway to route requests to the appropriate service and as a Load Balancer to distribute the load across multiple instances of the same service.
• Containerization: Docker is used to containerize each service, making it easy to deploy and scale the services.
• Deployment: Kubernetes is used to deploy and manage the services in a production environment, providing scalability, fault tolerance, and self-healing capabilities.
• CI/CD Pipeline: Github Actions is used for CI/CD to automate the deployment process, including building, testing, and deploying the services.
• Database: MongoDB is used as the database for all services, providing a flexible schema and scalability. Mongoose is used as the ODM to interact with MongoDB.
• Authentication & Authorization: JWT is used for authentication and argon2 is used for password hashing.

• Docker & Docker Compose should be installed.

  docker --version
  docker compose version

• Create and update all .env files with the required values for each service.

docker compose up --build

Here --build is used to build the image again if there are any changes in the code.

• Add DOCKER_USERNAME & DOCKER_PASSWORD to github secrets to push the image to docker hub.
