API Fundamentals

Master GitHub's REST and GraphQL APIs with enterprise authentication

Authentication

# Personal Access Token
curl -H "Authorization: token YOUR_TOKEN" \
  https://api.github.com/user

# GitHub App JWT
curl -H "Authorization: Bearer YOUR_JWT" \
  https://api.github.com/app

Rate Limiting

# Check rate limit
curl -H "Authorization: token YOUR_TOKEN" \
  https://api.github.com/rate_limit

# Response headers show limits
X-RateLimit-Remaining: 4999
X-RateLimit-Reset: 1625097600

GraphQL vs REST

# GraphQL - Single request
query {
  repository(owner: "octocat", name: "Hello-World") {
    issues(first: 10) {
      edges { node { title, state } }
    }
  }
}

Repository Automation

Automate repository management, branch policies, and release processes

Automated Repository Manager

class RepositoryManager {
  async createRepository(name, options = {}) {
    const response = await fetch('https://api.github.com/user/repos', {
      method: 'POST',
      headers: {
        'Authorization': `token ${this.token}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        name,
        private: options.private || false,
        auto_init: true,
        gitignore_template: options.gitignore || 'Node'
      })
    });
    
    if (response.ok) {
      const repo = await response.json();
      await this.setupBranchProtection(repo.full_name);
      return repo;
    }
  }

  async setupBranchProtection(repoName) {
    return fetch(`https://api.github.com/repos/${repoName}/branches/main/protection`, {
      method: 'PUT',
      headers: {
        'Authorization': `token ${this.token}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({
        required_status_checks: { strict: true, contexts: ['ci/tests'] },
        enforce_admins: true,
        required_pull_request_reviews: { required_approving_review_count: 2 }
      })
    });
  }
}
03

Workflow Integration

Control GitHub Actions and CI/CD pipelines programmatically

Workflow Controller

class WorkflowManager {
  async triggerWorkflow(owner, repo, workflowId, ref = 'main') {
    return fetch(`https://api.github.com/repos/${owner}/${repo}/actions/workflows/${workflowId}/dispatches`, {
      method: 'POST',
      headers: {
        'Authorization': `token ${this.token}`,
        'Content-Type': 'application/json'
      },
      body: JSON.stringify({ ref })
    });
  }

  async getWorkflowRuns(owner, repo) {
    const response = await fetch(`https://api.github.com/repos/${owner}/${repo}/actions/runs`);
    return response.json();
  }

  async downloadArtifact(owner, repo, artifactId) {
    const response = await fetch(
      `https://api.github.com/repos/${owner}/${repo}/actions/artifacts/${artifactId}/zip`,
      { headers: { 'Authorization': `token ${this.token}` } }
    );
    return response.blob();
  }
}

Enterprise Integration

Build comprehensive enterprise automation with monitoring and alerts

Enterprise Integration Hub

JIRA Sync

// Auto-sync GitHub issues with JIRA
async syncWithJira(issue) {
  const jiraIssue = {
    fields: {
      project: { key: 'PROJ' },
      summary: issue.title,
      description: issue.body,
      issuetype: { name: 'Task' }
    }
  };
  
  return fetch(`${this.jiraUrl}/rest/api/3/issue`, {
    method: 'POST',
    headers: { 
      'Authorization': `Basic ${this.jiraAuth}`,
      'Content-Type': 'application/json' 
    },
    body: JSON.stringify(jiraIssue)
  });
}

Slack Notifications

// Real-time Slack alerts
async notifySlack(event) {
  const message = {
    channel: '#dev-alerts',
    text: `🚀 ${event.action}: ${event.repository.name}`,
    attachments: [{
      color: event.action === 'opened' ? 'good' : 'warning',
      fields: [
        { title: 'Author', value: event.sender.login, short: true },
        { title: 'Repository', value: event.repository.full_name, short: true }
      ]
    }]
  };
  
  return fetch(this.slackWebhook, {
    method: 'POST',
    body: JSON.stringify(message)
  });
}

Monitoring Dashboard

// Real-time metrics collection
class GitHubMonitor {
  async collectMetrics() {
    const metrics = {
      repositories: await this.getRepoCount(),
      pullRequests: await this.getPRStats(),
      deployments: await this.getDeploymentStatus(),
      codeQuality: await this.getCodeQualityMetrics()
    };
    
    // Send to monitoring system
    await this.sendToDatadog(metrics);
    return metrics;
  }
}

API Gateway

// Secure API gateway with rate limiting
app.use('/api/github', rateLimit({
  windowMs: 15 * 60 * 1000, // 15 minutes
  max: 100 // limit each IP to 100 requests per windowMs
}));

app.use('/api/github', authenticateToken);

app.get('/api/github/repos', async (req, res) => {
  const repos = await github.getRepos(req.user.id);
  res.json(repos);
});
