Terms to know
Glossary
- Framework
- Code that calls yours. Next.js decides when your page component runs; a library like React is code you call.
- Server Component
- A component that runs only on the server and never ships to the browser. It changes where a component executes, not what a component is.
- Build output
- The artefact next build produces — prerendered HTML, static assets, and a server handler — which is what a host actually runs.
