6. CDN and Caching: Vercel's global edge network leverages CDN and caching techniques to deliver content quickly and efficiently, reducing the load on your servers.

Best practices for building web apps on Vercel

1. Optimize frontend code: Minimize and compress your JavaScript, CSS, and images to reduce load times and improve overall performance.
2. Implement caching strategies: Leverage Vercel's caching capabilities and cache-control headers to cache static assets and API responses, reducing the load on your backend and improving response times.
3. Use serverless functions wisely: Offload server-side logic to serverless functions to reduce the load on your backend servers and improve scalability.
4. Secure API routes: Use serverless functions to create API routes with built-in authentication and authorization checks to ensure that only authorized users can access sensitive data.
5. Monitor and analyze performance: Utilize Vercel's built-in performance monitoring tools and integration with third-party analytics platforms to identify bottlenecks and optimize your web app's performance.
6. Implement Content Security Policy (CSP) and other security measures: Protect your web app from malicious attacks by implementing a strong CSP and other security measures recommended by Vercel's security guidelines.
