summary

Shows concrete patterns from real production work: a media Optimizer and a transformation Builder shipped in the last 18 months. Demonstrates using TypeScript discriminated unions to make impossible states impossible, replacing Joi-style runtime validation with Zod parsers so types are inferred at compile time — parse don’t validate — and preferring composition and slot-style children over boolean prop configuration — favor composition over configuration. Replaces class-based repositories with closures to avoid action-at-a-distance, adopts dependency injection (stable params first) to cut tests and speed runs (Mocha timed ~8s faster in one experiment).
