TODO :: Web Api

A REST Web Api server in Haskell using chakra library.

Goals

The business layer must follow DDD, Event Sourcing & CQRS. The presistence layer should be agnostic and support plugable design, Postgresql, Cassandra, CouchDb, etc.,

Areas to explore:

• Event Sourced Domain Aggregates
• Persist domain events to event store
• Snapshotting the event stream store to reduce aggregates rebuilds
• Projection Store
• Stream API endpoints to stream any domain events from event store
• Integrate with message broker (RabbitMQ) to send Integration events
• Distributed domain aggregates (aka Actor) - requires cluster awarness, cloud-haskell

Dependencies

• Prometheus
• Grafana
• PostgreSQL
