Getting Started with Next.js 14

Next.js 14 brings exciting improvements to the React framework. Let's explore the key features.

The App Router

The App Router is a new way to build applications in Next.js. It uses React Server Components by default, which means:

- Better Performance: Less JavaScript sent to the client

• Improved SEO: Server-side rendering out of the box

• Simplified Data Fetching: Fetch data directly in components

Setting Up Your Project

``bash

npx create-next-app@latest my-app `

Key Concepts

Server Components

By default, all components in the App Router are Server Components. They run on the server and can:

- Access databases directly

• Keep sensitive data on the server

• Reduce client-side JavaScript

Client Components

When you need interactivity, use the "use client" directive:

`javascript

"use client"

import { useState } from "react"

export function Counter() { const [count, setCount] = useState(0) return setCount(c => c + 1)}>{count} } ``

Conclusion

Next.js 14 makes building web applications more intuitive and performant. Give it a try!
