Implement Core Workflows
Build one complete vertical slice first: route → UI → form → API → loading/error/success → tests. Once the pattern is stable, expand to additional features.
Avoid creating dozens of generic abstractions before you have repeated use cases. Let duplication reveal the correct abstraction boundary.
Key Takeaways
- Build vertical slices.
- Extract abstractions after repetition becomes clear.
- Keep user-visible behavior testable at each step.
