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

[deepgram-robot]

What to build

A working example of a SolidJS application that captures microphone audio in the browser and displays a live streaming transcript using Deepgram's WebSocket STT API — demonstrating SolidJS's fine-grained reactivity for efficient real-time UI updates.

Why this matters

SolidJS is a high-performance reactive UI framework with a growing developer community, offering fine-grained reactivity that is particularly well-suited for real-time streaming data like live transcription. Deepgram has examples for React, Vue.js, Angular, Svelte, and other frontend frameworks but no SolidJS example. Developers evaluating SolidJS for real-time applications need a reference implementation showing how Deepgram streaming STT integrates with SolidJS's signal-based reactivity model.

Suggested scope

• Language: TypeScript
• Framework: SolidJS (latest stable, with SolidStart optional)
• Deepgram APIs: Streaming STT (Nova-3) via WebSocket
• Includes: Microphone capture via getUserMedia, WebSocket connection to Deepgram, SolidJS signals for reactive transcript state, interim and final result handling, start/stop controls
• Complexity: Beginner — single component demonstrating the core pattern

Acceptance criteria

• Runnable with minimal setup (clone, add API key, npm install, run)
• README explains the SolidJS reactivity pattern for streaming data
• Uses current SDK version (or direct WebSocket if SDK doesn't support SolidJS)
• Live transcript updates in real-time with interim results
• Demonstrates SolidJS's fine-grained reactivity (no unnecessary re-renders)
• Includes start/stop recording controls
