Hi @plain dagger. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
Yes, you can have just a small portion of your server code be 'use client'. In Next.js, you can choose where to render your components based on their purpose. For smaller pieces of interactive UI, you can use Client Components. These are primarily rendered on the client, but with Next.js, they can also be pre-rendered on the server and hydrated on the client.
The 'use client' directive must be defined at the top of a file before any imports. It does not need to be defined in every file. The Client module boundary only needs to be defined once, at the "entry point", for all modules imported into it to be considered a Client Component.
Here's an example of a Client Component:
'use client'
import { useState } from 'react'
import { Carousel } from 'acme-carousel'
export default function Gallery() {
let [isOpen, setIsOpen] = useState(false)
return (
<div>
<button onClick={() => setIsOpen(true)}>View pictures</button>
{/* Works, since Carousel is used within a Client Component */}
{isOpen && <Carousel />}
</div>
)
}
In this example, the Gallery component is a Client Component because it uses the 'use client' directive. It uses client-only features like useState and can interact with other components that use client-only features, like the Carousel component from the acme-carousel package.
For more information, you can refer to the Next.js documentation on React Essentials (https://nextjs.org/docs/getting-started/react-essentials).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@rare kite Can I make just a portion of this code 'use client'

Let me check the knowledge base for you. One moment! :books:
To make a portion of your code 'use client', you would need to create a separate file for that portion of the code and add the 'use client' directive at the top of that file. This is because the 'use client' directive applies to the entire file it's placed in, and it must be defined at the top of the file before any imports.
Here's an example:
// app/client-component.js
'use client'
import { myAction } from './actions'
export default function ClientComponent() {
return (
<form action={myAction}>
<button type="submit">Add to Cart</button>
</form>
)
}
In this example, the ClientComponent is a Client Component because it uses the 'use client' directive. This component can then be imported and used in other parts of your application.
