# Deepgram Multi-Environment Setup ## Overview Configure isolated Deepgram environments for development, staging, and production. Each environment uses a separate Deepgram project, scoped API keys, environment-specific model selection, and validated configuration. Includes typed config, client factory, Docker Compose profiles, and Kubernetes overlays. ## Environment Strategy | Setting | Development | Staging | Production | |---------|------------|---------|------------| | Model | `base` (fast, cheap) | `nova-3` | `nova-3` | | Concurrency | 5 | 20 | 100 | | Diarization | Off | On | On | | PII Redaction | Off | On | On | | Callback URL | localhost:3000 | staging.example.com | api.example.com | | Key Rotation | Manual | Monthly | 90-day auto | ## Instructions ### Step 1: Typed Environment Configuration ```typescript interface DeepgramEnvConfig { apiKey: string; projectId: string; model: 'base' | 'nova-2' | 'nova-3'; maxConcurrency: number; features: { diarize: boolean; smart_format: boolean; redact: string[] | false; summarize: boolean; }; callbackBaseUrl?: string; timeout: number; } function loadConfig(env: string): DeepgramEnvConfig { const configs: Record<string, DeepgramEnvConfig> = { development: { apiKey: process.env.DEEPGRAM_API_KEY_DEV!, projectId: process.env.DEEPGRAM_PROJECT_ID_DEV!, model: 'base', maxConcurrency: 5, features: { diarize: false, smart_format: true, redact:...
