Note: This was originally a Next.js 13 tutorial. But since there are no API changes in Next.js 14, it's still completely up-to-date.

Learn & understand all important features and caching strategies of the new Next.js app router as fast as possible.

You will learn:
-the difference between React server components and client components and when to use which
-how to fetch, cache, and revalidate data in the new Next.js 13 app router (static rendering, dynamic rendering, and incremental static regeneration)
-how to use the new routing system and special files (loading.tsx, error.tsx, not-found.tsx, layout.tsx, route.tsx, and page.tsx)
-how to set up API route handlers (GET, POST, etc.) and how to use NextRequest and NextResponse in your backend
-how to use useRouter, useSearchParams, and usePathname from next/navigation
-how the Next.js pages directory compares to the new app router
-the app router equivalents of getStaticProps, getServerSideProps, getStaticPaths, next/Head, and dynamic routes
-how to make component libraries like Bootstrap work with server components
-how to set up (dynamic) metadata like page titles, descriptions, opengraph images, favicons, and more
-how to deploy your project to Vercel
