Learn how to build modern web applications with Next.js 14, featuring server components, app router, and more.
Next.js 14 introduces groundbreaking features that revolutionize how we build web applications. In this comprehensive guide, we'll explore the key concepts and best practices for building modern, performant web applications.
Server Components are at the heart of Next.js 14's innovations. They allow you to write React components that run on the server, reducing the JavaScript bundle sent to the client and improving initial page load performance.
The App Router brings a new paradigm to routing in Next.js applications. Built on React's latest features, it enables more intuitive and powerful routing patterns while maintaining excellent performance characteristics.
npx create-next-app@latest my-app --typescript --tailwind --appUse this command to create a new Next.js 14 project with TypeScript and Tailwind CSS support.
// app/page.tsx
async function getData() {
const res = await fetch('https://api.example.com/data')
return res.json()
}
export default async function Page() {
const data = await getData()
return (
<main>
<h1>Welcome to Next.js 14</h1>
<pre>{JSON.stringify(data, null, 2)}</pre>
</main>
)
}This example shows how to create a server component that fetches data and renders it. The component is async, allowing for direct data fetching without client-side JavaScript.
