"use client"

import { useState } from "react"

export default function Home() {

const [text, setText] = useState('hi')

return (
<div>
{text}
<div>lmao</div>
</div>
)
}

I checked the source of the page from the website, and the source has <body class="__className_e66fe9">
<div>hi<div>lmao</div>
</div>

Since the nextjs code has "use client", doesnt this mean that "hi" and "lmao" should not be in the source, as they are supposed to be rendered on the client side?

Hi @hot iris. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

The "use client" directive in Next.js is used to declare a boundary between Server and Client Component modules. This means that by defining a "use client" in a file, all other modules imported into it, including child components, are considered part of the client bundle - and will be rendered by React on the client (source (https://nextjs.org/docs/app/building-your-application/rendering/client-components)).

However, in your provided code, there is no "use client" directive. Therefore, the component Home is considered a Server Component by default in Next.js, and it will be server-rendered. This is why you see the rendered content ("hi" and "lmao") in the source of the page.

If you want to make Home a Client Component, you should add the "use client" directive at the top of your file, like this:

'use client'

import { useState } from "react"

export default function Home() {

  const [text, setText] = useState('hi')

  return (
    <div>
      {text}
      <div>lmao</div>
    </div>
  )
}

With this change, the Home component and its children will be rendered on the client side. However, please note that this will make the initial content of the component not visible in the page source, as it will be rendered in the browser after the JavaScript is downloaded and executed.

Let me check the knowledge base for you. One moment! :books:

I apologize for the confusion. If you have indeed declared "use client" at the top of your file, the component should be rendered on the client side. However, Next.js uses a hybrid rendering model, which means it can pre-render pages on the server side (SSR - Server Side Rendering) or generate static pages (SSG - Static Site Generation) at build time.

Even with the "use client" directive, during the build process, Next.js can still pre-render the page to HTML. This is why you see the rendered content ("hi" and "lmao") in the source of the page. The "use client" directive ensures that the component will be hydrated and become interactive on the client side after the JavaScript is downloaded and executed in the browser.

It's also worth noting that the "use client" directive is not a standard React or JavaScript feature, and its behavior might depend on the specific configuration of your Next.js application. If you're experiencing unexpected behavior, it might be worth checking your application's configuration or seeking help from the Next.js community or documentation.
