Introduction to Mock Service Worker (MSW)

Mock Service Worker (MSW) is a powerful mocking library designed to provide developers with control over their network requests, facilitating both testing and development. Unlike traditional mocking libraries that focus solely on testing, MSW allows developers to unblock themselves during application development by enabling them to describe network contracts even when backend teams may not be ready. This functionality helps maintain productivity as developers can present API contracts to backend engineers while still building front-end components. By integrating with existing architectures, MSW provides a seamless experience that enhances developer workflows.
