Getting Started with Next.js 15 and React Server Components

Next.js 15 introduces powerful new features that make building modern web applications easier and more efficient. In this article, we'll explore the key features and how to get started.

What's New in Next.js 15

Next.js 15 brings several exciting improvements:

React Server Components

React Server Components allow you to render components on the server, reducing the JavaScript bundle size and improving performance.

// This component runs on the server
export default async function ServerComponent() {
  const data = await fetch('https://api.example.com/data')
  const result = await data.json()

  return (
    
      
{result.title}
      
{result.description}
    
  )
}

Getting Started

To create a new Next.js 15 project:

npx create-next-app@latest my-app
cd my-app
npm run dev

Advanced Features

Server Actions

Server Actions provide a seamless way to handle form submissions and server-side logic:

'use server'

export async function createPost(formData) {
  const title = formData.get('title')
  const content = formData.get('content')

  // Save to database
  await savePost({ title, content })
}

Streaming and Suspense

Next.js 15 improves streaming capabilities:

import { Suspense } from 'react'

export default function Page() {
  return (
    
      
My Page
      Loading...
