Domain-Driven Design Showcase

Let's get concrete with Domain-Driven Design! This is a walk-through of code in an in-production application. All in one jam-packed video with no filler content!

You will see application design and code covering:

• Bounded contexts
• Aggregates
• Services
• Commands
• Domain Events
• Message handlers
• Website tactics enabled by events
• Durable messaging infrastructure and tactics
• Strategies for error handling
• Strategies for message de-duplication
  
• Making the most of cache with infinite time-to-live (and using events to ensure cache bust at the right time)
• How Domain-Driven Design links to Event-Driven Architecture

• startupconfessions.io Use Case diagram
• startupconfessions.io Sequence diagrams

The code is based on Vaughn Vernon's book Implementing Domain-Driven Design. 

Key takeaways

• Know how the concepts of Domain-Driven can look like in code
• Be able to reason on bounded contexts and the division of responsibilities in a system
• Have gained insight on messaging infrastructure from a Domain-Driven Design perspective
