Next.js 15 introduces Partial Prerendering (PPR) and deep integration with React Server Components. Let's dive in.
The shift to server-first data fetching has simplified state management significantly. We no longer need complex client-side libraries for basic data requirements.
Server Actions 2.0
With the latest update, Server Actions are now cacheable and can return UI components directly. This enables a "zero-API" architecture for many applications.
// server-action.ts
"use server";
export async function updateProfile(data) {
await db.user.update(data);
revalidatePath('/profile');
