Architecture
This application support division between client and server using Angular and .Net Core in each side correspondingly. A single-page application (SPA) is used to make the website feel more like a native app.
The architecture proposes a monolith approach with elaborate DDD/CQRS patterns.
WebSocket is the communication protocol between client apps and server. It has been used for synchronous and asynchronous communication as well.
MongoDb is used as a main source of data to store aggregates and domain events. Idempotency and distributed locking is maintained by Redis.
Domain events are handled in the server itself, by using MediatR, a simple in-process implementation the Mediator pattern. Cross-cutting concerns (logs, transaction etc) are handled by decorators.
Message queues are based on Azure queues, to convey integration events.
Sms sender is third party tool that notify clients and is triggered by messages in queue.
