Microservice based app in golang

-- The application demonstrates how to use microservices to create a scalable and maintainable architecture

Architecture / Services

• API Gateway: The entry point for all client requests.
• Authentication Service: Handles user authentication.
• Logger Service: Page application events.
• Mailer Service: Sends emails.
• Listener Service: Listens for events from RabbitMQ and processes them.

Tech stack

• Golang: The primary language.
• Docker: Used for containerizing the services.
• Docker Compose: Used for orchestrating the multi-container Docker application.
• RabbitMQ: Used for messaging between services.
• PostgreSQL: The database used by the Authentication Service.
• MongoDB: The database used by the Logger Service.
• gRPC: Communication method between api-gateway and other services where it needs async calls.
