Building and Deploying Serverless Applications with NextJS and Vercel

// Your serverless function code here

By utilizing Vercel’s serverless functions, you can enhance your NextJS application with server-side functionality, improve performance, and simplify your overall architecture. This approach allows you to focus on building a great user experience, while Vercel takes care of the server management and scaling.

Optimizing Performance and Scalability

Building a high-performance and scalable application is essential for delivering a great user experience. In this section, we’ll explore various techniques and best practices for optimizing the performance and scalability of your NextJS serverless application deployed on Vercel.

● Incremental Static Regeneration (ISR)

ISR allows you to update static pages without rebuilding your entire application. By specifying a revalidate property in your getStaticProps function, you can tell NextJS to periodically regenerate the page with updated data. This approach combines the benefits of static site generation with the dynamic nature of server-side rendering. export async function getStaticProps(context) {

// Fetch data from an API or database const data = await fetchData();
