Multi-Page Applications (MPA) MPAs reload the page on every navigation.
Pros:
Simple architecture.
Full HTML is delivered on first load.
When pages are mostly static, they can be effectively cached and delivered by a CDN.
Cons:
Navigation is slower due to full page reloads.
Dynamic updates require complete page refreshes.
Single-Page Applications (SPA) SPAs load content dynamically on the client. This means the initial HTML is essentially empty.

( < p > Loading data... </ p > ) : ( < pre > { JSON . stringify ( data , null , 2 ) } </ pre > ) } </ div > ); }
Pros:
Fast in-page navigation.
Dynamic interactivity.
Cons:
Minimal initial HTML.
Heavy reliance on client-side JavaScript.
SPA-influenced Isomorphic Initial HTML is rendered on the server for SEO and fast first paint, then hydrated on the client to enable interactivity.

Pros:
SEO-friendly full HTML is delivered initially.
Cons:
Requires coordination between client and server.
More complex setup.
MPA-influenced Split Execution Mostly/Fully HTML rendered on the server using server actions.

Pros:
CDN-friendly HTML delivery.
Minimal client-side code.
Excellent SEO.
Cons:
Client-side interactivity may require additional handling.
Increased server CPU consumption.

Why Server Components Matter 📚 Further Reading 🧠 Final Thoughts Each rendering strategy has its strengths. MPAs are straightforward and, when mostly static, can be effectively cached via a CDN; SPAs deliver dynamic interactivity entirely on the client (resulting in minimal initial HTML); SPA-influenced Isomorphic approaches combine SEO and dynamic updates by server-rendering the initial HTML and hydrating on the client; and MPA influenced Split Execution offers performance with server-handled mutations using server actions.
