[Suggestion] Astro real-time streaming transcription with WebSocket (TypeScript)

[deepgram-robot]

What to build

A working example of real-time audio transcription in an Astro application — using Astro's SSR mode with a WebSocket endpoint that bridges browser microphone audio to Deepgram's streaming STT, with live transcript updates rendered via Astro's island architecture.

Why this matters

Astro has become one of the fastest-growing web frameworks (50K+ GitHub stars), particularly popular for content-rich sites, documentation platforms, and developer tools. Developers building with Astro who need voice features currently have no reference for integrating real-time STT. Astro's island architecture (where interactive components hydrate independently) is a natural fit for a transcription widget that can be dropped into any Astro page. Covering Astro expands Deepgram's framework reach into a rapidly growing ecosystem.

Suggested scope

• Language: TypeScript
• Framework: Astro (latest stable) with SSR adapter (Node.js)
• Deepgram APIs: Streaming STT (Nova-3) with smart formatting
• Architecture:
  • Astro SSR endpoint handling WebSocket upgrade
  • Browser island component: mic capture → WebSocket → live transcript display
  • Server: WebSocket bridge forwarding audio to Deepgram STT
  • Client island: React or Svelte component (Astro island) showing live transcript
• Includes: Start/stop recording controls, interim vs final result styling, copy transcript button
• Complexity: Low-medium — standard WebSocket bridge pattern in Astro's SSR context

Acceptance criteria

• Runnable with minimal setup (clone, add API key, npm install, run)
• README explains Astro SSR + WebSocket setup
• Uses current SDK version and latest stable Astro
• Demonstrates Astro island architecture for the interactive transcription component
• Shows both interim and final transcription results with visual distinction
• Deployable to Astro-supported hosts (Vercel, Netlify, Node.js)
