Welcome to Next.js 14
Next.js 14 represents a major evolution in React development. With features like Server Components, Server Actions, and Partial Prerendering, it's redefining how we build web applications.
App Router Deep Dive
The App Router introduces a new paradigm for routing and data fetching:
File-Based Routing
app/
page.tsx → /
about/
page.tsx → /about
blog/
[slug]/
page.tsx → /blog/:slugLayouts and Templates
// app/layout.tsx
export default function RootLayout({ children }) {
return (
<html lang="en">
<body>{children}</body>
</html>
);
}Server Components by Default
In Next.js 14, components are Server Components by default. This means:
Server Actions
Server Actions allow you to run server code from client components:
async function submitForm(formData: FormData) {
'use server';
const email = formData.get('email');
await saveToDatabase(email);
}Conclusion
Next.js 14 is a game-changer for React development. Embrace the new patterns and enjoy the improved developer experience.
