Deepgram CI Integration

Examples

Run unit/schema tests on every pull request with mocked Deepgram responses. Execute one trusted protected-branch integration test against a development project using a short licensed fixture and a scoped secret; retain redacted status/metrics on failure and never inject the key into forked or untrusted CI workflows.

Overview

Set up CI/CD pipelines for Deepgram integrations with GitHub Actions. Includes unit tests with mocked SDK, integration tests against the real API, smoke tests, automated key rotation, and deployment gates.

Prerequisites

• GitHub repository with Actions enabled
• DEEPGRAM_API_KEY stored as repository secret
• @deepgram/sdk and vitest installed
• Test fixtures committed (or downloaded in CI)

Instructions

Step 1: GitHub Actions Workflow

# .github/workflows/deepgram-ci.yml
name: Deepgram CI

on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

env:
  NODE_VERSION: '20'

jobs:
  unit-tests:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ env.NODE_VERSION }}
          cache: npm
      - run: npm ci
      - run: npm run lint
      - run: npm run typecheck
      - run: npm test -- --reporter=verbose
        # Unit tests use mocked SDK — no API key needed

  integration-tests:
    runs-on: ubuntu-latest
    needs: unit-tests
    if: github.event_name == 'push' || github.event.pull_request.head.repo.full_name == github.repository
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ env.NODE_VERSION }}
          cache: npm
      - run: npm ci
      - run: npm run test:integration
        env:
          DEEPGRAM_API_KEY: ${{ secrets.DEEPGRAM_API_KEY }}
        timeout-minutes: 5

  smoke-test:
    runs-on: ubuntu-latest
    needs: integration-tests
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: ${{ env.NODE_VERSION }}
          cache: npm
      - run: npm ci && npm run build
      - name: Smoke test
        run: npx tsx scripts/smoke-test.ts
        env:
          DEEPGRAM_API_KEY: ${{ secrets.DEEPGRAM_API_KEY }}
        timeout-minutes: 2

Step 2: Integration Test Suite

// tests/integration/deepgram.test.ts
import { describe, it, expect, beforeAll } from 'vitest';
import { createClient, DeepgramClient } from '@deepgram/sdk';

const SAMPLE_URL = 'https://static.deepgram.com/examples/Bueller-Life-moves-702702706.wav';

describe('Deepgram Integration', () => {
  let client: DeepgramClient;

  beforeAll(() => {
    const key = process.env.DEEPGRAM_API_KEY;
    if (!key) throw new Error('DEEPGRAM_API_KEY required for integration tests');
    client = createClient(key);
  });

  it('authenticates successfully', async () => {
    const { result, error } = await client.manage.getProjects();
    expect(error).toBeNull();
    expect(result.projects.length).toBeGreaterThan(0);
  });

  it('transcribes pre-recorded audio with Nova-3', async () => {
    const { result, error } = await client.listen.prerecorded.transcribeUrl(
      { url: SAMPLE_URL },
      { model: 'nova-3', smart_format: true }
    );
    expect(error).toBeNull();
    const alt = result.results.channels[0].alternatives[0];
    expect(alt.transcript).toContain('Life');
    expect(alt.confidence).toBeGreaterThan(0.85);
  }, 30000);

  it('returns word-level timing', async () => {
    const { result } = await client.listen.prerecorded.transcribeUrl(
      { url: SAMPLE_URL },
      { model: 'nova-3' }
    );
    const words = result.results.channels[0].alternatives[0].words;
    expect(words).toBeDefined();
    expect(words!.length).toBeGreaterThan(0);
    expect(words![0]).toHaveProperty('start');
    expect(words![0]).toHaveProperty('end');
    expect(words![0]).toHaveProperty('confidence');
  }, 30000);

  it('speaker diarization identifies speakers', async () => {
    const { result } = await client.listen.prerecorded.transcribeUrl(
      { url: SAMPLE_URL },
      { model: 'nova-3', diarize: true }
    );
    const words = result.results.channels[0].alternatives[0].words;
    expect(words?.some((w: any) => w.speaker !== undefined)).toBe(true);
  }, 30000);

  it('TTS generates audio stream', async () => {
    const response = await client.speak.request(
      { text: 'CI test.' },
      { model: 'aura-2-thalia-en', encoding: 'linear16', container: 'wav' }
    );
    const stream = await response.getStream();
    expect(stream).toBeTruthy();
  }, 15000);
});

Step 3: Smoke Test Script

// scripts/smoke-test.ts
import { createClient } from '@deepgram/sdk';

const SAMPLE_URL = 'https://static.deepgram.com/examples/Bueller-Life-moves-702702706.wav';

async function smokeTest() {
  console.log('Deepgram Smoke Test');
  console.log('='.repeat(40));

  const client = createClient(process.env.DEEPGRAM_API_KEY!);
  let passed = 0;
  let failed = 0;

  // Test 1: Authentication
  try {
    const { error } = await client.manage.getProjects();
    if (error) throw error;
    console.log('[PASS] Authentication');
    passed++;
  } catch (err: any) {
    console.error(`[FAIL] Authentication: ${err.message}`);
    failed++;
  }

  // Test 2: Pre-recorded transcription
  try {
    const { result, error } = await client.listen.prerecorded.transcribeUrl(
      { url: SAMPLE_URL },
      { model: 'nova-3', smart_format: true }
    );
    if (error) throw error;
    if (!result.results.channels[0].alternatives[0].transcript) {
      throw new Error('Empty transcript');
    }
    console.log('[PASS] Pre-recorded transcription');
    passed++;
  } catch (err: any) {
    console.error(`[FAIL] Pre-recorded transcription: ${err.message}`);
    failed++;
  }

  // Test 3: TTS
  try {
    const response = await client.speak.request(
      { text: 'Smoke test.' },
      { model: 'aura-2-thalia-en' }
    );
    const stream = await response.getStream();
    if (!stream) throw new Error('No audio stream');
    console.log('[PASS] Text-to-speech');
    passed++;
  } catch (err: any) {
    console.error(`[FAIL] Text-to-speech: ${err.message}`);
    failed++;
  }

  console.log(`\nResults: ${passed} passed, ${failed} failed`);
  process.exit(failed > 0 ? 1 : 0);
}

smokeTest();

Step 4: Package.json Scripts

{
  "scripts": {
    "test": "vitest run",
    "test:watch": "vitest --watch",
    "test:integration": "vitest run tests/integration/",
    "test:smoke": "tsx scripts/smoke-test.ts",
    "lint": "eslint src/ tests/",
    "typecheck": "tsc --noEmit"
  }
}

Step 5: Vitest Configuration

// vitest.config.ts
import { defineConfig } from 'vitest/config';

export default defineConfig({
  test: {
    globals: true,
    environment: 'node',
    include: ['tests/**/*.test.ts'],
    exclude: ['tests/integration/**'],  // Integration tests run separately
    coverage: {
      include: ['src/**'],
      reporter: ['text', 'lcov'],
    },
  },
});

Step 6: Automated Key Rotation (Scheduled)

# .github/workflows/rotate-deepgram-key.yml
name: Rotate Deepgram API Key

on:
  schedule:
    - cron: '0 0 1 */3 *'  # Quarterly (1st of every 3rd month)
  workflow_dispatch:

jobs:
  rotate:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npm ci
      - name: Rotate key
        run: |
          NEW_KEY=$(npx tsx scripts/rotate-key.ts)
          gh secret set DEEPGRAM_API_KEY --body "$NEW_KEY"
          echo "Key rotated successfully"
        env:
          DEEPGRAM_ADMIN_KEY: ${{ secrets.DEEPGRAM_ADMIN_KEY }}
          DEEPGRAM_PROJECT_ID: ${{ secrets.DEEPGRAM_PROJECT_ID }}
          GH_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Output

• GitHub Actions workflow (unit -> integration -> smoke)
• Integration test suite covering STT, diarization, TTS
• Smoke test script with pass/fail exit codes
• Vitest configuration with integration test separation
• Quarterly key rotation workflow
