msw

What problem does it solve?

This Skill simplifies API mocking for frontend development and testing, allowing you to simulate network requests and responses without relying on a live backend.

Core Features & Use Cases

• Network Interception: Mock REST and GraphQL APIs at the network level in both browser and Node.js environments.
• Request Handlers: Define specific handlers for different HTTP methods (GET, POST, PUT, DELETE, PATCH) and routes, including support for query parameters, headers, and dynamic responses.
• Testing Integration: Seamlessly integrate with testing frameworks like Vitest and Jest for robust end-to-end and unit testing.
• Development Workflow: Develop frontend applications independently of backend availability, simulate error conditions, and test loading states.

Quick Start

Use the msw skill to set up API mocking in your React application by running npx msw init public/ --save.
