This Skill removes the guesswork from configuring MSW so API mocks behave consistently in development and tests. It helps you avoid silent handler mismatches, flaky test isolation problems, and outdated v1 syntax.
Ask for an MSW v2 setup or handler refactor that follows these best practices and applies the right rules to your project.

API mocking with MSW v2 requires configuring the correct browser or Node.js entrypoint, managing the worker or server lifecycle, and setting unhandled-request behavior to ensure consistent interception in development and tests.
Mocked API requests fail to intercept due to silent handler mismatches, outdated v1 syntax, or cache leakage. Diagnose interception issues by verifying explicit request body parsing and correct MSW v2 URL matching rules.
To mock GraphQL operations in MSW v2, organize request handlers by domain and use the proper v2 handler syntax to model GraphQL operations, ensuring explicit request parsing and correct response patterns for your queries and mutations.
Yes, you can use MSW to mock authentication, cookies, delays, streaming, and file uploads. Advanced mocking scenarios also support modeling sequential flows and passthroughs within your isolated test lifecycle management.
The best way to isolate API mocks and prevent flaky concurrent test pollution is to implement isolated test lifecycle management with handler resets and unhandled-request errors, while diagnosing fake timer conflicts and cache leakage.
Migrating from MSW v1 to v2 requires updating request handler syntax, refactoring handlers to use explicit request parsing, and returning responses with the correct MSW v2 syntax to harden tests and standardize mocking behavior.
