Queue: Express.js + React full-stack live transcription (TypeScript)

[github-actions]

Integration: Express.js + React Live STT

Origin

Requested in #32: "A full-stack application with an Express.js backend and React frontend that demonstrates real-time live transcription."

What this should show

• Express.js backend that proxies WebSocket connections to Deepgram Live STT (Nova-3)
• API key stays server-side — never exposed to the browser
• React frontend (Vite) captures microphone audio via MediaRecorder/getUserMedia
• Streams audio through the Express WebSocket proxy to Deepgram
• Displays live transcripts in the React UI with interim and final results
• Speaker diarization support when multiple speakers detected
• Monorepo structure with clear client/ and server/ directories
• TypeScript throughout (both frontend and backend)

Credentials likely needed

• only DEEPGRAM_API_KEY
