Static and Dynamic RenderingIn Next.js, a route can be statically or dynamically rendered.
In a static route, components are rendered on the server at build time. The result of the work is cached and reused on subsequent requests.
In a dynamic route, components are rendered on the server at request time.
Static Rendering (Default)
By default, Next.js statically renders routes to improve performance. This means all the rendering work is done ahead of time and can be served from a Content Delivery Network (CDN) geographically closer to the user.
Static Data Fetching (Default)
By default, Next.js will cache the result of fetch() requests that do not specifically opt out of caching behavior. This means that fetch requests that do not set a cache option will use the force-cache option.
If any fetch requests in the route use the revalidate option, the route will be re-rendered statically during revalidation.
