TypeScript Models for Medication API Responses
Use discriminated unions and nullable clinical fields to prevent optimistic assumptions.
Define result states
Define result states is the first design decision for medication API TypeScript. Use discriminated unions and nullable clinical fields to prevent optimistic assumptions. Write the boundary down before choosing endpoints or drawing clinical-looking UI so reviewers can test the actual promise.
Model nullable fields
For medication API TypeScript, model nullable fields should remain observable rather than becoming hidden adapter behavior. Give resolution, lookup, and interpretation separate states, then decide which failures a user may retry.
Narrow errors safely
Narrow errors safely needs an operational test, not only a happy-path example. Add a bounded timeout, stable error handling, request IDs, privacy-safe logging, and a fixture that proves the medication API TypeScript workflow fails closed.
