SSR (Server-Side Rendering)
A rendering strategy where HTML is generated on the server for each request, rather than in the browser via JavaScript.
SSR improves FCP and LCP compared to client-side rendering (CSR) because the browser receives complete HTML immediately rather than waiting for JavaScript to generate content. However, SSR increases server load and TTFB if not optimised. Next.js, Nuxt.js, and SvelteKit all support SSR. The trade-off between SSR, SSG, and CSR is a key web performance architectural decision.
