Type-Driven Domain Design in Go: Encoding Invariants at Compile Time
📰 Dev.to · Gabriel Anhaia
Learn how to encode invariants at compile time in Go using type-driven domain design to reduce runtime bugs
Action Steps
- Apply the parse-don't-validate pattern to encode data validation at compile time
- Use states-as-types to represent different states of an object as distinct types
- Implement phantom types to add additional constraints to existing types
- Refactor existing code to use type-driven domain design
- Test and verify the effectiveness of type-driven domain design in reducing runtime bugs
Who Needs to Know This
This technique benefits Go developers and teams working on complex systems, as it helps catch errors early and improves code maintainability
