Domain-driven design

This hands-on workshop is a practical introduction for developers and architects who wish to discover the basic ideas behind CQRS & Event Sourcing and how those patterns leverage Domain-Driven Design. We start off with a basic CRUD service for a social network as we gradually apply a combination of CQRS and Event-sourcing patterns while enforcing basic DDD principles.

This workshop is a practical introduction for developers and architects who wish to discover the basic ideas behind CQRS & Event Sourcing.

What will I learn

CRUD limitations

Read/Write models coupling problem
Performance & Scalability limitations
How CRUD limits Domain-driven design
Exemplify by showing a social-network service implementation

Shifting to CQRS & Domain-driven design

The CQRS concept
CQRS benefits
CQRS considerations (Eventual Consistency, Implementation Complexity)
Modeling the Write Model using DDD patterns (Aggregates & Repositories)
The CQRS flow
Exemplify by implementing a CQRS-based social-network service (TypeScript)

Shifting to Event-sourcing

The Event-sourcing data-persistence pattern
Event-sourcing benefits & considerations
How Event-sourcing leverages Domain-driven design
