Introduction

NestJS has @nestjs/swagger for REST. Socket.IO gateways have nothing.

wsgate fills that gap — an interactive browser UI like Swagger UI, but for your WebSocket events. Decorate your gateway handlers with @WsDoc() and get an interactive UI to emit events, inspect payloads, and watch live responses without writing a single test client.

Features

• Decorator-driven — metadata collected at decoration time, zero DI scanning
• Interactive UI — emit events and inspect responses in real time
• Monaco Editor — JSON payload editing with validation and faker support
• Code generation — generate client code in 9+ languages
• Multi-namespace — groups events by namespace automatically
• Zero config — one line in main.ts, no root module changes
