Data fetching help need

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

Yes, you should create a separate Client Component that includes the "use client" directive and wraps the DataContext.Provider. This will allow you to use the context within your Server Components without any issues.

Here's an example of how you can create a separate Client Component for the provider:

1. Create a new file called data-provider.tsx:

// data-provider.tsx
'use client';

import DataContext from '@/contexts/user-data-context';

export default function DataProvider({ children, data }) {
  return <DataContext.Provider value={data}>{children}</DataContext.Provider>;
}

2. Update your DashboardLayout to use the new DataProvider component:

// DashboardLayout
import HeaderBar from '@/components/globals/header-bar';
import DataProvider from './data-provider';
import { resolve } from '@/graphql';

export default async function DashboardLayout({ children }: { children: React.ReactNode }) {
  const data = await resolve(({ query }) => {
    return {
      self: query.self,
      organizations: query.organizations,
    };
  });

  return (
    <DataProvider data={data}>
      <HeaderBar />
      <main>{children}</main>
    </DataProvider>
  );
}

By doing this, you're wrapping the DataContext.Provider within a Client Component, which will resolve the error you're encountering.

For more information on using context in Client Components, refer to the Next.js documentation (https://nextjs.org/docs/getting-started/react-essentials#using-context-in-client-components).

Sorry @drifting moss, I seem to be having a bit of trouble. Don't worry though, I've pinged my supprt and they will try to fix me up! :technologist:

Perhaps try again in 15mins?

Unhandled Runtime Error
Error: Depth limit reached at query.self.sessions.user.sessions.user.sessions.user.sessions.user.sessions.user.sessions.user.__typename, ignoring further selections.

It seems like you're encountering a depth limit error in your GraphQL query. This error occurs when the query has too many nested levels, which can lead to performance issues or circular references.

To resolve this issue, you should refactor your GraphQL query to reduce the depth of the nested fields. You might need to split the query into multiple smaller queries or use fragments to avoid deeply nested selections.

Unfortunately, I don't have the exact code for your GraphQL query from the provided extracts. However, you can refer to the GraphQL documentation (https://graphql.org/learn/queries/) to learn more about structuring queries and handling nested fields.

@deft quail this happened as a result of me using the code you provided to me. I tried it in my codebase and I started getting this issue.

I apologize for the confusion. Based on the provided extracts, I don't have enough information to give you a confident solution to the issue you're facing. However, I recommend reviewing your GraphQL query and making sure it doesn't have circular references or excessive nesting.

@deft quail I am getting the following error:

Warning: Only plain objects can be passed to Client Components from Server Components. Objects with toJSON methods are not supported. Convert it manually to a simple value before passing it to props.
  [{__typename: undefined, createdAt: ..., email: ..., id: ..., name: ..., platformId: ..., provider: ..., updatedAt: ...}]
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

This is the layout for the route group I am working in/on:

import HeaderBar from "@/components/globals/header-bar";
import DataProvider from "./data-provider";
import { resolve } from "@/graphql";

export default async function DashboardLayout({ children }: { children: React.ReactNode }) {
  // TODO: Why the HELL is this data being fetched recursively?!?!?
  const data = await resolve(({ query }) => {
    return {
      self: {
        ...query.self,
      },
      organizations: {
        ...query.organizations,
      },
    };
  });

  console.log(data);

  return (
    <DataProvider data={data}>
      <HeaderBar />
      <main>{children}</main>
    </DataProvider>
  );
}

And this is "DataProvider":

"use client";

import DataContext, { type ContextDataType } from "@/contexts/user-data-context";

export default function DataProvider({ children, data }: { children: React.ReactNode; data: ContextDataType }) {
  return <DataContext.Provider value={data}>{children}</DataContext.Provider>;
}

How do I fix this?

The warning you're encountering is because you're passing non-plain objects from Server Components to Client Components. To fix this issue, you need to convert the non-plain objects to plain objects before passing them to the DataProvider.

You can use the JSON.parse(JSON.stringify(obj)) method to convert the non-plain objects to plain objects. Update your DashboardLayout as follows:

import HeaderBar from "@/components/globals/header-bar";
import DataProvider from "./data-provider";
import { resolve } from "@/graphql";

export default async function DashboardLayout({ children }: { children: React.ReactNode }) {
  const data = await resolve(({ query }) => {
    return {
      self: {
        ...query.self,
      },
      organizations: {
        ...query.organizations,
      },
    };
  });

  // Convert non-plain objects to plain objects
  const plainData = JSON.parse(JSON.stringify(data));

  return (
    <DataProvider data={plainData}>
      <HeaderBar />
      <main>{children}</main>
    </DataProvider>
  );
}

This should resolve the warning you're facing. For more information on passing props from Server to Client Components, refer to the Next.js documentation (https://nextjs.org/docs/getting-started/react-essentials#passing-props-from-server-to-client-components).

@deft quail Why do I need to do this then? is there a more elegant way to fetch data like e.g. user data server-side (in a route group layout file) and then pass it to a client component (page)?

[deft quail]

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

You need to convert non-plain objects to plain objects because React Server Components have certain restrictions when passing data from Server Components to Client Components. The data must be serializable, which means that only plain objects can be passed between them.

A more elegant way to fetch data server-side and pass it to a client component is to use a data-fetching library like SWR (https://swr.vercel.app/) or React Query (https://tanstack.com/query/v4/). These libraries can help you fetch, cache, and manage the data more efficiently.

For example, you can fetch data in your layout using SWR:

// components/layout.js
import useSWR from 'swr';
import Navbar from './navbar';
import Footer from './footer';

export default function Layout({ children }) {
  const { data, error } = useSWR('/api/navigation', fetcher);

  if (error) return <div>Failed to load</div>;
  if (!data) return <div>Loading...</div>;

  return (
    <>
      <Navbar links={data.links} />
      <main>{children}</main>
      <Footer />
    </>
  );
}

Then, in your page component, you can use the fetched data directly without having to pass it down through props.

For more information on data fetching in Next.js, refer to the Next.js documentation (https://nextjs.org/docs/app/building-your-application/data-fetching).

@deft quail I have a page as follows:

import { Card, CardContent, CardDescription, CardFooter, CardHeader, CardTitle } from "@/components/ui/card";
import { Box } from "lucide-react";
import { getServers } from "@/lib/data-fetching/userdata";

export default async function ServersOverview() {
  const data = await getServers();

  console.log(data);

  return (
    <main className={"p-8 pt-6"}>
      <div className="grid grid-cols-2">
        <Card className={"border-l-green-500 border-l-[6px] box-border"}>
          <CardHeader className={""}>
            <div className={"p-[18px]"}>
              <Box />
            </div>
            <CardTitle>Server Name</CardTitle>
            <CardDescription></CardDescription>
          </CardHeader>
        </Card>
      </div>
    </main>
  );
}

And the getServers() function has to take in data which I am currently storing inside of a global react context store, but I then can't use async server functions to fetch the data server side which is an issue. What should I do? If it helps, the route for this page also is "/servers".
