Event Sourcing and CQRS in a Mobile Client with .NET MAUI and LiteDB | Community Feed

Traditional CRUD struggles with offline support, reliable sync, and state consistency across sessions. This guide shows how storing events rather than current state — combined with CQRS — makes resilient, offline-first .NET MAUI apps far cleaner, using the lightweight embedded LiteDB for local persistence.

What you’ll learn

Why Event Sourcing suits mobile: offline-first queuing, full audit history, easier conflict resolution, and reactive UI
How CQRS separates commands (writes) from queries (reads) and why that fits mobile so well
A step-by-step build: base DomainEvent, a LiteDB-backed event store, commands and handlers, and projections/read models
Rebuilding state by replaying events, and wiring it all into MAUI via dependency injection and an ObservableObject ViewModel
A CRUD-vs-Event-Sourcing comparison, plus mobile-specific challenges (storage growth, sync conflicts, replay cost) and pro-level patterns like snapshots, sync queues, and remote event sync

Worth a read if your app needs offline support, traceability, or complex workflows.
