Architecture

The backend consists of 3 microservices which utilize RabbitMQ and GRPC to communicate with each other and send messages via SignalR to the frontend React Native application.

Backend stack:

• NET 6
• SQL Server / PostgreSQL (Entity ORM)
• CockroachDB
• SignalR
• GRPC
• JWT Authentication
• RabbitMQ
• Docker
• Kubernetes
• Azure App Services

Frontend stack:

• React Native
• Expo SDK 44
• SignalR Client
• JWT Authentication
• Google auth
• Native-base
• Netlify

Communication between Microservices

Embracing eventual consistency pattern, we use the RabbitMQ message bus to send messages between the microservices and we "pull" for any missing data whenever a microservice starts.
