#CQRS

As a single model grows complex, reads and writes start tripping each other up. Here's how CQRS solves that problem — from simple separation to full event sourcing, with TypeScript examples throughout.

From simple CRUD to an append-only log of immutable events. We dissect Event Sourcing—the architecture behind scalable financial systems. Learn why it pairs perfectly with CQRS, how to handle the versioning of events (Schema Evolution), and the trade-offs involved in complexity versus auditability.

In complex domains, using a single data model for both reading and writing can lead to performance bottlenecks and messy code. Learn how CQRS (Command Query Responsibility Segregation) coupled with Event Sourcing can decouple your architecture, improve scalability, and simplify domain logic.
