Server-Side Rendering

Definitions

1. The technique of generating a page's full HTML on the server for each request (or at build time in the static variant), sending a complete document to the browser so content is visible before client-side JavaScript loads and hydrates the page for interactivity.

   In plain English: Building the complete webpage on the server so users see content immediately instead of waiting for JavaScript to draw it in the browser.

   Example: "We switched to server-side rendering for the marketing pages — time-to-first-contentful-paint dropped from 3.2s to 800ms."
