# Apollo Local Dev Loop

## Overview

Set up an efficient local development workflow for Apollo.io integrations. Includes sandbox API key support, MSW mock server for offline testing, request logging, and npm scripts for daily development. Apollo provides a **sandbox API token** that returns dummy data without consuming credits.

## Prerequisites

- Completed `apollo-install-auth` setup
- Node.js 18+
- Git repository initialized

## Instructions

### Step 1: Set Up Environment Files

Apollo offers a sandbox token for testing. Generate one at Settings > Integrations > API Keys > Sandbox.

```bash
# .env.example (commit this — team reference)
APOLLO_API_KEY=your-api-key-here
APOLLO_SANDBOX_KEY=your-sandbox-key-here
APOLLO_USE_SANDBOX=false

# .env (gitignored — copy from example)
cp .env.example .env
echo '.env' >> .gitignore
echo '.env.local' >> .gitignore
```

### Step 2: Create a Dev Client with Request Logging

```typescript
// src/apollo/dev-client.ts
import axios from 'axios';
import dotenv from 'dotenv';

dotenv.config();

const apiKey = process.env.APOLLO_USE_SANDBOX === 'true'
  ? process.env.APOLLO_SANDBOX_KEY
  : process.env.APOLLO_API_KEY;

export const devClient = axios.create({
  baseURL: 'https://api.apollo.io/api/v1',
  headers: {
    'Content-Type': 'application/json',
    'x-api-key': apiKey!,
  },
  timeout: 30_000,
});

// Log request shape in development; never print contact fields or credentials.
devClient.interceptors.request.use((config) => {
  console.log(`[Apollo] ${config.method?.toUpperCase()} ${config.url}`);
  if (config.data && typeof config.data === 'object') {
    console.log('[Apollo] Body fields:', Object.keys(config.data).sort().join(', '));
  }
  return config;
});

devClient.interceptors.response.use(
  (res) => {
    const remaining = res.headers['x-rate-limit-remaining'];
    console.log(`[Apollo] ${res.status} ${res.config.url}${remaining ? ` — ${remaining} req remaining` : ''}`);
    return res;
  },
  (err) => {
    console.error(`[Apollo] ERROR ${err.response?.status}: ${err.response?.data?.message ?? err.message}`);
    return Promise.reject(err);
  },
);
```

### Step 3: Set Up MSW Mock Server for Offline Testing

```typescript
// src/mocks/apollo-handlers.ts
import { http, HttpResponse } from 'msw';

const BASE = 'https://api.apollo.io/api/v1';

export const apolloHandlers = [
  // People Search (free endpoint)
  http.post(`${BASE}/mixed_people/api_search`, () =>
    HttpResponse.json({
      people: [
        { id: 'mock-1', name: 'Jane Doe', title: 'VP Sales', organization: { name: 'Acme Corp' } },
        { id: 'mock-2', name: 'John Smith', title: 'Director Engineering', organization: { name: 'Acme Corp' } },
      ],
      pagination: { page: 1, per_page: 25, total_entries: 2, total_pages: 1 },
    }),
  ),

  // People Enrichment
  http.post(`${BASE}/people/match`, () =>
    HttpResponse.json({
      person: {
        id: 'mock-enriched', name: 'Jane Doe', email: '[email protected]',
        title: 'VP Sales', organization: { name: 'Acme Corp' },
        phone_numbers: [{ sanitized_number: '+14155551234' }],
        linkedin_url: 'https://www.linkedin.com/in/janedoe',
      },
    }),
  ),

  // Organization Enrichment
  http.get(`${BASE}/organizations/enrich`, ({ request }) => {
    const url = new URL(request.url);
    return HttpResponse.json({
      organization: {
        id: 'mock-org', name: 'Acme Corp', industry: 'Technology',
        estimated_num_employees: 250, annual_revenue_printed: '$25M',
        primary_domain: url.searchParams.get('domain') ?? 'acme.com',
      },
    });
  }),

  // Search for Sequences
  http.post(`${BASE}/emailer_campaigns/search`, () =>
    HttpResponse.json({
      emailer_campaigns: [
        { id: 'seq-1', name: 'Q1 Outbound', active: true, num_steps: 4 },
      ],
    }),
  ),

  // Auth Health
  http.get(`${BASE}/auth/health`, () =>
    HttpResponse.json({ is_logged_in: true }),
  ),
];
```

```typescript
// src/mocks/server.ts
import { setupServer } from 'msw/node';
import { apolloHandlers } from './apollo-handlers';
export const mockServer = setupServer(...apolloHandlers);
```

### Step 4: Configure Vitest

```typescript
// vitest.config.ts
import { defineConfig } from 'vitest/config';
export default defineConfig({
  test: { setupFiles: ['./src/mocks/setup.ts'], environment: 'node' },
});

// src/mocks/setup.ts
import { mockServer } from './server';
import { beforeAll, afterAll, afterEach } from 'vitest';
beforeAll(() => mockServer.listen({ onUnhandledRequest: 'warn' }));
afterEach(() => mockServer.resetHandlers());
afterAll(() => mockServer.close());
```

```typescript
// src/__tests__/people-search.test.ts
import { describe, it, expect } from 'vitest';
import { devClient } from '../apollo/dev-client';

describe('Apollo People Search', () => {
  it('returns contacts from mock server', async () => {
    const { data } = await devClient.post('/mixed_people/api_search', {
      q_organization_domains_list: ['acme.com'],
      per_page: 10,
    });
    expect(data.people).toHaveLength(2);
    expect(data.people[0].name).toBe('Jane Doe');
  });
});
```

### Step 5: Add Development Scripts

```json
{
  "scripts": {
    "dev": "tsx watch src/index.ts",
    "test": "vitest",
    "test:watch": "vitest --watch",
    "test:live": "APOLLO_USE_SANDBOX=false vitest --run",
    "test:sandbox": "APOLLO_USE_SANDBOX=true vitest --run
