About
By introducing a standardized way to write mocks — request handlers — MSW allows you to reuse the same mock definitions in multiple environments and for various purposes: testing, development, debugging.
Rich support for REST and GraphQL API makes it silly-easy to cover your use cases and enable fast prototyping via a mock-first development.
