Mock Service Worker
Mock Service Worker is an API mocking library that intercepts requests at the network level using Service Workers. It allows developers to write client-agnostic mocks and reuse them across various frameworks, tools, and environments such as unit tests, integration tests, and local development. By leveraging standard Fetch API and web standards, it eliminates the need for dedicated mock servers and enables seamless mocking for both REST and GraphQL APIs.
