[Suggestion] Hono real-time streaming transcription on Cloudflare Workers (TypeScript)

[deepgram-robot]

What to build

A working example of real-time audio streaming transcription using Hono (the fast-growing edge web framework) deployed to Cloudflare Workers, with Deepgram's streaming STT API.

Why this matters

Hono has rapidly become the go-to framework for Cloudflare Workers, Deno Deploy, and Bun — it's the fastest growing JavaScript server framework in the edge/serverless space. Developers building edge-native voice applications with Hono have no reference implementation for integrating Deepgram's streaming WebSocket API. The existing Cloudflare Worker example (#110) uses vanilla Workers API; Hono developers expect framework-idiomatic patterns with middleware, typed routes, and WebSocket helpers.

Suggested scope

• Language: TypeScript
• Framework: Hono (v4+) on Cloudflare Workers
• Deepgram APIs: STT (streaming WebSocket via Nova-3)
• What it should include:
  • Hono WebSocket route that proxies browser audio to Deepgram
  • Client-side HTML page with microphone capture
  • Hono middleware for API key validation
  • Streaming transcript display in the browser
  • wrangler.toml for Cloudflare deployment
• Complexity: Low-medium — straightforward WebSocket proxy pattern

Acceptance criteria

• Runnable with minimal setup (clone, add API key, wrangler dev)
• README explains the Hono + Cloudflare Workers setup
• Uses current Hono and Deepgram SDK versions
• Includes both local dev and Cloudflare deployment instructions
• Demonstrates streaming transcription with sub-second latency
