integration-testing

Automate frontend-backend integration testing by running end-to-end checks that validate cross-origin requests, API response structures, and clean builds across separate TypeScript services. This enforces consistent API boundary types and build hygiene.

Configure multi-origin CORS support by applying standardized patterns for cross-origin requests during integration testing. This validates CORS preflight responses using curl and browser Network tools across distinct frontend and backend services.

API contract validation enforces boundaries by applying explicit Api* types and boundary transformations. It checks the API shape during integration testing to ensure frontend and backend services maintain consistent data structures.

Yes, this integration testing approach is designed for full-stack TypeScript projects with separate frontend and backend services. It validates cross-origin requests, API contracts, and build hygiene across the independent services.

Prevent build artifacts from shadowing source files by applying prebuild and ignore rules. This enforces build artifact hygiene, ensuring clean pre-build checks and validating that compiled outputs do not overwrite original source files.

CORS preflight failures during integration often stem from missing multi-origin support or inconsistent configuration. Standardizing CORS patterns and validating preflight responses with curl helps resolve cross-origin request issues between services.
