# Exa CI Integration

## Overview

Set up CI/CD pipelines for Exa integrations with unit tests (mocked), integration tests (real API), and health checks. Uses GitHub Actions with secrets for API key management.

## Prerequisites

- GitHub repository with Actions enabled
- Exa API key for testing
- npm/pnpm project with vitest or jest

## Instructions

### Step 1: GitHub Actions Workflow

```yaml
# .github/workflows/exa-tests.yml
name: Exa Integration Tests

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

jobs:
  unit-tests:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: "20"
          cache: "npm"
      - run: npm ci
      - run: npm run test:unit
        # Unit tests use mocked Exa — no API key needed

  integration-tests:
    runs-on: ubuntu-latest
    # Only run if API key is available (not on forks)
    if: github.event_name == 'push' || github.event.pull_request.head.repo.full_name == github.repository
    env:
      EXA_API_KEY: ${{ secrets.EXA_API_KEY }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: "20"
          cache: "npm"
      - run: npm ci
      - run: npm run test:integration
        timeout-minutes: 5

  exa-health-check:
    runs-on: ubuntu-latest
    env:
      EXA_API_KEY: ${{ secrets.EXA_API_KEY }}
    steps:
      - name: Verify Exa API connectivity
        run: |
          HTTP_CODE=$(curl -s -o /dev/null -w "%{http_code}" \
            -X POST https://api.exa.ai/search \
            -H "x-api-key: $EXA_API_KEY" \
            -H "Content-Type: application/json" \
            -d '{"query":"CI health check","numResults":1}')
          echo "Exa API status: $HTTP_CODE"
          [ "$HTTP_CODE" = "200" ] || exit 1
```

### Step 2: Configure Secrets

```bash
# Add API key as repository secret
gh secret set EXA_API_KEY --body "your-exa-api-key"

# For staging/production deployments
gh secret set EXA_API_KEY_STAGING --body "staging-key" --env staging
gh secret set EXA_API_KEY_PROD --body "prod-key" --env production
```

### Step 3: Integration Test Suite

```typescript
// tests/exa.integration.test.ts
import { describe, it, expect } from "vitest";
import Exa from "exa-js";

const describeWithKey = process.env.EXA_API_KEY ? describe : describe.skip;

describeWithKey("Exa API Integration", () => {
  const exa = new Exa(process.env.EXA_API_KEY!);

  it("should search and return results", async () => {
    const result = await exa.search("JavaScript frameworks", {
      type: "auto",
      numResults: 3,
    });
    expect(result.results.length).toBeGreaterThanOrEqual(1);
    expect(result.results[0]).toHaveProperty("url");
    expect(result.results[0]).toHaveProperty("title");
    expect(result.results[0]).toHaveProperty("score");
  }, 10000);

  it("should return content with searchAndContents", async () => {
    const result = await exa.searchAndContents("Node.js best practices", {
      numResults: 2,
      text: { maxCharacters: 500 },
      highlights: { maxCharacters: 200 },
    });
    expect(result.results[0].text).toBeDefined();
    expect(result.results[0].text!.length).toBeGreaterThan(0);
  }, 15000);

  it("should find similar pages", async () => {
    const result = await exa.findSimilar("https://nodejs.org", {
      numResults: 3,
    });
    expect(result.results.length).toBeGreaterThanOrEqual(1);
  }, 10000);

  it("should handle invalid queries gracefully", async () => {
    // Empty query should return 400
    await expect(
      exa.search("", { numResults: 1 })
    ).rejects.toThrow();
  }, 10000);
});
```

### Step 4: Release Gate with Exa Verification

```yaml
# .github/workflows/release.yml
on:
  push:
    tags: ["v*"]

jobs:
  verify-and-release:
    runs-on: ubuntu-latest
    env:
      EXA_API_KEY: ${{ secrets.EXA_API_KEY_PROD }}
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: "20"
      - run: npm ci
      - run: npm test
      - name: Verify Exa production connectivity
        run: npm run test:integration
      - run: npm run build
      - run: npm publish
```

## Error Handling

| Issue | Cause | Solution |
|-------|-------|----------|
| Secret not found | Missing configuration | `gh secret set EXA_API_KEY` |
| Integration tests timeout | Slow API response | Increase timeout to 15000ms |
| Tests fail on forks | No access to secrets | Skip integration tests on fork PRs |
| Rate limited in CI | Too many concurrent runs | Use unique test queries per run |
