Next.js 14 introduces a groundbreaking feature: the ability to seamlessly import server components within client components This innovation enhances the performance and flexibility of Next.js applications, allowing developers to create dynamic and efficient web experiences.

Server Components in Next.js14:

In the realm of Next.js, server components are JavaScript modules executed server-side during the build phase. This functionality enables developers to seamlessly fetch data, execute server-side logic, and dynamically render content before transmitting it to the client. The integration of server components not only streamlines performance but also facilitates swifter page loads by alleviating client-side processing burdens.

Client Component in Next.js14:

client components within Next.js are JavaScript modules designed to operate on the client-side, predominantly within the browser environment. These components play a pivotal role in managing user interactions, orchestrating UI updates, and executing client-side logic, thereby fostering the development of interactive and dynamic web applications.

Import Server component within Client component:

The ability to import server components within client components opens up new possibilities for building Next.js applications. Developers can now leverage the server-side functionality and data processing capabilities of server components directly within client components, enabling more efficient and flexible application development.

follow steps :

1.Create Next.js App :

npx create-next-app@latest

2.Create server component here is a example:

async function getData() {
  const res = await fetch('https://api.example.com/...')
  // The return value is *not* serialized
  // You can return Date, Map, Set, etc.
 
  if (!res.ok) {
    // This will activate the closest `error.js` Error Boundary
    throw new Error('Failed to fetch data')
  }
 
  return res.json()
}
 
export default async function Server() {
  const data = await getData()
 
  return <div> 
         <h1> Server Component</h1>
          //fetch data here
         </div>
    
}

3.create client component here is an example :

'use client'
import { useState } from 'react'
 
export default function Counter() {
  const [count, setCount] = useState(0)
 
  return (
    <div>
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>Click me</button>
    </div>
  )
}

4.import Couter.js into parent page and pass Server.js as a props

import React from "react";
import Couter from "./Counter";
import Server from "./Server";
import 
export default function Home() {
  return (
    <>
      <Counter child={<Server/>}/>
    </>
  );
}


5.get props in client component Couter.js

'use client'
import { useState } from 'react'
 
export default function Counter({child}) {
  const [count, setCount] = useState(0)
 
  return (
    <div>
      <div>{child}</div> //this serever component
      <p>You clicked {count} times</p>
      <button onClick={() => setCount(count + 1)}>Click me</button>
    </div>
  )
}

Conclusion:

Incorporating server components into Next.js represents a paradigm shift in modern web development, offering developers unparalleled flexibility, performance, and scalability. By leveraging server-side execution during the build phase, developers can optimize performance, streamline data fetching, and deliver dynamic content tailored to individual user preferences. As the digital landscape continues to evolve, server components emerge as a cornerstone of next-generation web applications, empowering developers to create faster, more efficient, and more engaging user experiences.
