Getting a grip on your code dependencies - Dennis Doomen - NDC Sydney 2024
Learn how to master your code dependencies, reduce duplication, and increase maintainability by recognizing internal boundaries, using abstractions, and implementing dependency injection, event sourcing, and more.
- The talk emphasizes the importance of understanding code dependencies and finding ways to manage them effectively.
- Code duplication can be reduced by identifying internal boundaries and creating separate modules.
- Using abstractions and interfaces can help decouple code and make it more maintainable.
- Dependency injection and the law of demeter can be used to reduce coupling and increase cohesion.
- The talk also touches on the idea of event sourcing and the importance of building a safety net to handle changes.
- The code base should be organized into functional slices, each with its own boundaries and tests.
- The onion architecture is mentioned as a way to separate concerns and reduce dependencies.
- Code should be organized into build blocks that serve specific purposes, and each block should be treated as a separate boundary.
- Using testing tools and mocking can help isolate dependencies.
- Code should be deleted if it is unnecessary, redundant, or difficult to understand.
- The talk concludes that getting a grip on dependencies is crucial for building maintainable and scalable code.
