getStaticProps when statically exported?getStaticProps to fetch data at build time. What will be the behavior of this page when you run next export to create a static export?export async function getStaticProps() { return { props: { message: 'Hello from static props!' } }; } export default function Page({ message }) { return <div>{message}</div>; }
getStaticProps runs and what next export does.getStaticProps runs at build time and fetches data to be included in the static HTML. When you run next export, Next.js generates static HTML files with the data already included. So the page serves fully static content with the message visible immediately.
getStaticProps runs at build time and enables static generation. getServerSideProps runs on every request and disables static export. getInitialProps is legacy and not compatible with static export. A page without data fetching can be static, but to explicitly disable SSR and fetch data at build time, use getStaticProps.
next export fail when using getServerSideProps?next export on a Next.js project, but the build fails with an error related to getServerSideProps. Why does this happen?export async function getServerSideProps() { return { props: { time: Date.now() } }; } export default function Page({ time }) { return <div>{time}</div>; }
next export produces and what getServerSideProps needs.getServerSideProps runs on the server for every request, so it requires a Node.js server at runtime. next export generates static HTML files and does not run a server, so it cannot support getServerSideProps. This causes the build to fail.
getStaticProps with dynamic data?next export?export async function getStaticProps() { const date = new Date().toISOString(); return { props: { date } }; } export default function Page({ date }) { return <div>Build time: {date}</div>; }
getStaticProps runs and what data is included in static HTML.getStaticProps runs once at build time and fetches the current date. This date is included in the static HTML generated by next export. So the HTML shows the build time, not the current time when the user visits.
next export) compared to server rendering?next export for static export in Next.js projects.next export generates static HTML and assets only. It does not support API routes or any server-side code because there is no server to run them. React hooks and CSS modules work fine with static export. Static exports can be deployed to CDNs easily.
