Building and Deploying Serverless Applications with NextJS and Vercel

logging, simply use the console.log, console.error, or other console methods within your serverless function: export default async function handler(req, res) {

// Your serverless function code here console log('A custom log message'); res.json({ data: 'Your data here' });

● Third-Party Monitoring and Analytics Tools

In addition to Vercel’s built-in analytics, you can also integrate third-party monitoring and analytics tools with your NextJS application, such as Google Analytics, LogRocket, or Sentry. These tools can provide additional insights into user behavior, error tracking, and application performance. To integrate a third-party tool, follow the specific integration instructions provided by the tool’s documentation.

● Performance Audits

Regularly auditing your application’s performance using tools like Google Lighthouse or WebPageTest can help you identify areas for improvement and ensure your application remains fast and responsive. These tools provide detailed reports on various performance metrics, including load times, accessibility, and best practices.
