Streamlines API mocking using MSW handlers and environment-specific setups for consistent development and testing.
This skill provides a comprehensive framework for implementing Mock Service Worker (MSW) within Claude Code projects. It enforces industry best practices by separating mock data from handler logic, managing the critical distinction between browser workers and Node servers, and providing structured patterns for response variants. By automating the setup of type-safe mocks, it enables developers to simulate complex API scenarios, network latency, and error states reliably across both local development environments and automated test suites.
