แนะนำ Next.js 15

Next.js 15 is a React framework for building fast, SEO-friendly, production-ready web apps — basically React with superpowers bolted on.

Next.js is a React framework for full-stack apps: you still build UIs with React, but it adds server logic and production-grade optimizations.

React handles the UI; Next.js solves the rest — faster loads via server rendering, real SEO, code splitting, and structure for big apps.

The App Router is built on React Server Components. Folders become routes automatically, so pages, layouts, and data stay clean and organized.

Next.js can render pages two ways: SSR builds HTML per request, SSG builds it at build time. Both ship ready HTML for fast first loads.

Server Actions let you run server code straight from a component — handling form submits and DB calls without writing separate API routes.

Under the hood it's still React: you build the UI from React components, exactly as you would in a plain React project. Here's a simple one.

Next.js 15 adds the React Compiler for automatic optimization, smarter caching for faster loads, and stable Server Actions.

Spin up a new project with npx create-next-app@latest — it scaffolds every file and config you need. We will dig into setup next lesson.

Which of the following is NOT a primary benefit of using Next.js compared to a plain React application for building production websites?

You learned the Next.js 15 essentials: a full-stack React framework with the App Router, SSR/SSG rendering, Server Actions, and the React Compiler.
