I deployed my hobby Nextjs (latest version) to vercel, and noticed i keep getting "this function has timed out" error. After inspecting the logs, i noticed that every page route (using the Link component / home page when first entering the website) request is actually a serverless function, even though some pages are marked with "use client" and have no API calls to the api route in my app. Is this the default behavior? How can i stop every single page route request from being a serverless function as its crashing my website when cold starting my backend server as it is also hosted on a free tier and takes about 15-20 seconds on average to spin back up. Pauline P. Narvas (@pawlean) · 2024-08-06 · ♥ 1 Hi, @cohen-tal! To prevent every page route request in your Next.js app on Vercel from becoming a serverless function, you need to use **Static Site Generation (SSG)** with `getStaticProps` or **Client-Side Rendering (CSR)** with data fetching inside `useEffect`, avoiding methods like `getServerSideProps` or `getInitialProps` that trigger **server-side rendering (SSR)**. This minimizes reliance on serverless functions, mitigating the "function timeout" errors caused by backend cold starts. You can also verify your `next.config.js` and Vercel deployment settings to avoid any misconfigurations that enforce SSR.
