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

Yes, when creating an action file to fetch data in a server component, you need to define 'use server' at the top of the file. This marks all functions within the file as Server Actions that can be reused in both Client and Server Components.
Here is how you can modify your code to include the 'use server' directive:
'use server';
import prisma from '@/app/libs/prismadb';
export default async function getSuggestedEvents(
category: string,
region: string,
) {
try {
const today = new Date();
const suggestedEvents = await prisma.event.findMany({
where: {
categories: { has: category },
region: region,
startDate: { gt: today.toISOString() },
},
orderBy: {
startDate: 'asc',
},
take: 6,
});
const safeSuggestedEvents = suggestedEvents.map((event) => ({
...event,
createdAt: event.createdAt.toISOString(),
}));
return safeSuggestedEvents;
} catch (error) {
throw new Error('Error fetching suggested events');
}
}
By adding 'use server' at the top of the file, you ensure that all functions within the file are treated as Server Actions. This is necessary for the functions to be properly recognized and executed in a server-side context.
For more information, you can refer to the Next.js documentation on Server Actions and Mutations (https://nextjs.org/docs/app/building-your-application/data-fetching/server-actions-and-mutations#convention).
Note: you can ask me a follow up question by @ mentioning me again :speech_balloon:

@desert dove but this function is working and fetching data properly without any issue in a server componet without adding 'use server' at the top. Why it's happening?

Let me check the knowledge base for you. One moment! :books:
The reason your function is working and fetching data properly in a server component without adding 'use server' at the top is that Server Components in Next.js are server-rendered by default. This means that any data fetching logic you include in a Server Component will inherently run on the server.
However, the 'use server' directive is specifically used to mark functions as Server Actions, which can be reused in both Client and Server Components. If you are only using the function within a Server Component, it will work without the 'use server' directive because the Server Component itself ensures server-side execution.
Here is a summary of the key points:
- Server Components: These are server-rendered by default, so any data fetching logic within them will run on the server without needing the
'use server'directive. - 'use server' Directive: This is used to mark functions as Server Actions, making them reusable in both Client and Server Components. It is necessary when you want to explicitly define a function as a Server Action, especially if you plan to use it in a Client Component.
For more detailed information, you can refer to the Next.js documentation on Server Components and Route Handlers (https://nextjs.org/docs/app/building-your-application/data-fetching/fetching-caching-and-revalidating#fetching-data-on-the-client-with-route-handlers).
