Pattern

The composable functions pattern uses:

• Interfaces defining dependencies (data + side effects) and function contracts

• Pure functions that receive injected dependencies

• Mock factories for testing

• Adapters (RSC/Hooks) that wire up real dependencies

Workflow

• Read the example structure in example/ to understand the patterns

• Ask the user for the feature name

• Generate minimal boilerplate in src/features/<feature-name>/ with:

• entity/<feature>.interfaces.ts

• dependency and function interfaces

• functions/<feature>.functions.ts

• pure functions with DI

• functions/<feature>.functions.mock.ts

• mock factory

• functions/<feature>.functions.test.ts

• test file

• Ask the user what adapter type to create:

• RSC (React Server Components) - default

• React Hooks - default

• Other (API, proxy-handler, etc.) - search codebase for examples, otherwise improvise

• Generate the adapter in adapters/<feature>.<type>.adapter.ts

Do not implement business logic - generate bare minimum boilerplate only.
