Sample Implementation

Here's the core Worker code structure:

export default {
  async scheduled(event, env, ctx) {
    // Runs daily via Cron trigger
    const vpnData = await fetchVPNData();
    const processed = processAndValidate(vpnData);
    
    // Store in KV with timestamp
    await env.VPN_DATA.put('latest', JSON.stringify({
      vpns: processed.vpns,
      securityTools: processed.tools,
      lastUpdated: new Date().toISOString()
    }), {
      expirationTtl: 86400 // 24 hours
    });
  },
  
  async fetch(request, env) {
    // Serve data to frontend
    const data = await env.VPN_DATA.get('latest');
    
    return new Response(data, {
      headers: {
        'Content-Type': 'application/json',
        'Cache-Control': 'public, max-age=3600',
        'Access-Control-Allow-Origin': '*'
      }
    });
  }
};
