You separate domain logic from external dependencies in TypeScript by using *.system.ts files as thin wrappers. These system files contain no business logic and support dependency injection through constructor parameters, ensuring your domain layer remains isolated and platform-agnostic.

The namespace API pattern for TypeScript module scaffolding uses classes with static methods to organize domain logic. It includes folder structures with index.ts barrel exports, providing a structured and clean way to expose module functionality without instantiating classes.

You configure test coverage exclusions for system wrappers in TypeScript by adding rules to your bunfig.toml file. Specifically, you exclude patterns like {domain}.*.system.ts and related files from coverage reports to focus metrics on business logic.

Yes, clean architecture in TypeScript works with Azure SDK and Cloudflare APIs by defining minimal interface contracts. You name these contracts with the I{Domain} convention to keep the surface area minimal and your application completely platform-agnostic.

You wire dependencies using dependency injection in TypeScript modules by passing a dependencies object and overriding defaults as needed. This approach allows you to inject external systems seamlessly during module instantiation or refactoring.

You should refactor TypeScript modules to use interface-based dependency injection when creating modules with external dependencies, writing system wrappers, or needing configurable test coverage exclusions. It enforces clean-architecture patterns for scalable application growth.
