Deepgram Multi Env Setup

Deepgram Multi-Environment Setup

Overview

Configure isolated Deepgram environments for development, staging, and production with proper configuration management.

Prerequisites

• Access to Deepgram Console
• Multiple Deepgram projects (recommended)
• Environment management system
• Secret management solution

Environment Strategy

Instructions

Step 1: Create Deepgram Projects

Create separate projects in Deepgram Console for each environment.

Step 2: Configure API Keys

Generate environment-specific API keys with appropriate scopes.

Step 3: Implement Config Management

Create configuration system for environment switching.

Step 4: Set Up Secret Management

Securely store and access API keys per environment.

Examples

Environment Configuration

// config/deepgram.ts
interface DeepgramConfig {
  apiKey: string;
  projectId: string;
  model: string;
  features: {
    diarization: boolean;
    smartFormat: boolean;
    punctuate: boolean;
  };
  limits: {
    maxConcurrent: number;
    maxDurationMinutes: number;
  };
  callbacks: {
    baseUrl: string;
  };
}

const configs: Record<string, DeepgramConfig> = {
  development: {
    apiKey: process.env.DEEPGRAM_API_KEY_DEV!,
    projectId: process.env.DEEPGRAM_PROJECT_ID_DEV!,
    model: 'base',
    features: {
      diarization: false,
      smartFormat: true,
      punctuate: true,
    },
    limits: {
      maxConcurrent: 5,
      maxDurationMinutes: 10,
    },
    callbacks: {
      baseUrl: 'http://localhost:3000',
    },
  },
  staging: {
    apiKey: process.env.DEEPGRAM_API_KEY_STAGING!,
    projectId: process.env.DEEPGRAM_PROJECT_ID_STAGING!,
    model: 'nova-2',
    features: {
      diarization: true,
      smartFormat: true,
      punctuate: true,
    },
    limits: {
      maxConcurrent: 20,
      maxDurationMinutes: 60,
    },
    callbacks: {
      baseUrl: 'https://staging.example.com',
    },
  },
  production: {
    apiKey: process.env.DEEPGRAM_API_KEY_PRODUCTION!,
    projectId: process.env.DEEPGRAM_PROJECT_ID_PRODUCTION!,
    model: 'nova-2',
    features: {
      diarization: true,
      smartFormat: true,
      punctuate: true,
    },
    limits: {
      maxConcurrent: 100,
      maxDurationMinutes: 180,
    },
    callbacks: {
      baseUrl: 'https://api.example.com',
    },
  },
};

export function getConfig(): DeepgramConfig {
  const env = process.env.NODE_ENV || 'development';
  const config = configs[env];

  if (!config) {
    throw new Error(`Unknown environment: ${env}`);
  }

  if (!config.apiKey) {
    throw new Error(`DEEPGRAM_API_KEY not set for ${env}`);
  }

  return config;
}

Environment-Aware Client Factory

// lib/deepgram-factory.ts
import { createClient, DeepgramClient } from '@deepgram/sdk';
import { getConfig } from '../config/deepgram';

let clients: Map<string, DeepgramClient> = new Map();

export function getDeepgramClient(): DeepgramClient {
  const config = getConfig();
  const env = process.env.NODE_ENV || 'development';

  if (!clients.has(env)) {
    clients.set(env, createClient(config.apiKey));
  }

  return clients.get(env)!;
}

export function resetClients(): void {
  clients.clear();
}

// Transcribe with environment-specific settings
export async function transcribe(audioUrl: string) {
  const client = getDeepgramClient();
  const config = getConfig();

  const { result, error } = await client.listen.prerecorded.transcribeUrl(
    { url: audioUrl },
    {
      model: config.model,
      smart_format: config.features.smartFormat,
      punctuate: config.features.punctuate,
      diarize: config.features.diarization,
    }
  );

  if (error) throw error;
  return result;
}
