# MSW (Mock Service Worker) Documentation

MSW is an API mocking library for browser and Node.js that intercepts outgoing requests at the network level using Service Workers (browser) or class extension (Node.js). It supports HTTP, GraphQL, WebSocket, and Server-Sent Events mocking.

## Quick Reference

| Task | Entry Point |
|------|-------------|
| Getting started | `contents/quick-start.mdx` |

| GraphQL mocking | `contents/graphql/index.mdx` |
| WebSocket mocking | `contents/websocket/index.mdx` |
| Server-Sent Events | `contents/sse/index.mdx` |
| API reference | `contents/api/http.mdx`, `contents/api/graphql.mdx` |
| Browser setup | `contents/integrations/browser.mdx` |
| Node.js setup | `contents/integrations/node.mdx` |
| Debugging | `contents/runbook.mdx` |

## When to use

Use this skill when the user asks about:
- Setting up MSW for browser or Node.js environments
