nextjs app router

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

In Next.js, the App Router is a new feature that allows you to build your application using a single app directory instead of the traditional pages directory. It introduces a new way of handling data fetching and routing in your application.

However, based on the code you provided, it seems you're trying to define a Server Action (searchUser) inside a Client Component (Settings). This is not allowed in Next.js. Server Actions should be defined in separate files and imported into your components.

Here's how you can refactor your code:

First, move your searchUser function to a separate file:

// app/serverActions/searchUser.tsx
'use server'

export default async function searchUser(data: string) {
  // Your search logic here
}

Then, import and use it in your component:

// app/components/Settings.tsx
import searchUser from '../serverActions/searchUser';

// ...

const handleSearchInput = async (data: string) => {
  const response = await searchUser(data);
};

// ...

Remember, in the app directory, all components are React Server Components by default, and data fetching happens securely on the server. You can fetch data using the familiar async and await syntax, and there are no new APIs to learn.

For more information, you can refer to the following resources:

• Next.js App Router (https://nextjs.org/docs/app/building-your-application/upgrading/app-router-migration)
• Data Fetching with Next.js (https://nextjs.org/docs/app/building-your-application/data-fetching)
• Server Actions in Next.js (https://nextjs.org/docs/app/api-reference/functions/server-actions)

@trail hull async/await is not yet supported in Client Components, only Server Components. This error is often caused by accidentally adding 'use client' to a module that was originally written for the server.

'use client';

import ThreeColumnInfo from '../components/ThreeColumnInfo';
import UsersTable from '../components/UsersTable';
import PageHeader from '@components/PageHeader';
import TableSearch from '@components/Table/TableSearch';
import Text from '@components/typography/Text';
import ChangeStatus from '@components/Modal/ChangeStatus';

// types
import { UserType } from '@customTypes/user';

// server actions
import getUsers from '@serverActions/user/getusers';
import searchUser from '@serverActions/user/searchUser';

import { useDebounce } from 'use-debounce';
import { useState, useEffect } from 'react';

function Settings() {
const [users, setUsers] = useState<UserType[] | []>([]);

useEffect(() => {
const fetchusers = async () => {
try {
const users = await getUsers();

    setUsers(users.data);
  } catch (error) {
    alert(error);
  }
};

fetchusers();

}, []);

// const handleSearchInput = async (data: string) => {
// const response = await searchUser(data);
// };

return (
<>
<PageHeader title="Settings" />
<ThreeColumnInfo />
<Text size="lg" weight="semibold" className="mb-30px">
User Settings
</Text>
{/* <TableSearch
title="LIST OF USERS"
buttonTitle="Add User"
url="settings/create-user"
// handleSearchInput={handleSearchInput}
/> /}
<UsersTable users={users} />
{/ <ChangeStatus /> */}
</>
);
}

export default Settings;

In Next.js, async/await is not supported in Client Components. This is because Client Components are primarily rendered on the client-side, and using async/await in these components can lead to unexpected behavior.

In your code, you've correctly commented out the handleSearchInput function which was using async/await. This function was causing the error because it was defined in a Client Component (Settings), which is marked with 'use client'.

If you need to fetch data in a Client Component, you should use Server Components or Server Actions. In your case, you've already defined getUsers as a Server Action and used it in your useEffect hook. This is the correct way to fetch data in Next.js.

Here's your refactored code:

'use client';

import ThreeColumnInfo from '../components/ThreeColumnInfo';
import UsersTable from '../components/UsersTable';
import PageHeader from '@components/PageHeader';
import TableSearch from '@components/Table/TableSearch';
import Text from '@components/typography/Text';
import ChangeStatus from '@components/Modal/ChangeStatus';

// types
import { UserType } from '@customTypes/user';

// server actions
import getUsers from '@serverActions/user/getusers';
import searchUser from '@serverActions/user/searchUser';

import { useDebounce } from 'use-debounce';
import { useState, useEffect } from 'react';

function Settings() {
  const [users, setUsers] = useState<UserType[] | []>([]);

  useEffect(() => {
    const fetchusers = async () => {
      try {
        const users = await getUsers();

        setUsers(users.data);
      } catch (error) {
        alert(error);
      }
    };

    fetchusers();
  }, []);

return (
<>
<PageHeader title="Settings" />
<ThreeColumnInfo />
<Text size="lg" weight="semibold" className="mb-30px">
User Settings
</Text>
<UsersTable users={users} />
{/* <ChangeStatus /> */}
</>
);
}

export default Settings;

For more information, you can refer to the **Next.js documentation on Client Components** (<https://nextjs.org/docs/messages/no-async-client-component>).

@trail hull It is not allowed to define inline "use server" annotated Server Actions in Client Components.
│ To use Server Actions in a Client Component, you can either export them from a separate file with "use server" at the top, or pass them down through props from a Server Component.

'use client';

import ThreeColumnInfo from '../components/ThreeColumnInfo';
import UsersTable from '../components/UsersTable';
import PageHeader from '@components/PageHeader';
import TableSearch from '@components/Table/TableSearch';
import Text from '@components/typography/Text';

import ChangeStatus from '@components/Modal/ChangeStatus';

// server actions
import getUsers from '@serverActions/user/getusers';
import searchUser from '@serverActions/user/searchUser';

import { useDebounce } from 'use-debounce';
import { useState, useEffect } from 'react';

function Settings() {
const [users, setUsers] = useState([]);

useEffect(() => {
'use server';
const fetch = async () => {
const users = getUsers();

  setUsers(users);
};

fetch();

}, []);

return (
<>
<PageHeader title="Settings" />
<ThreeColumnInfo />
<Text size="lg" weight="semibold" className="mb-30px">
User Settings
</Text>

  <UsersTable users={users} />
  {/* <ChangeStatus /> */}
</>

);
}

export default Settings;

'use server';

async function getUsers() {
try {
const res = await fetch(${process.env.NEXTAUTH_URL}/users, {
method: 'GET',
headers: {
'api-secret': ${process.env.NEXT_API_KEY},
'Content-Type': 'application/json',
'Access-Control-Allow-Origin': '*',
},
next: {
tags: ['users'],
},
});

const result = await res.json();

return result;

} catch (error) {
throw new Error('Failed to get users');
}
}
export default getUsers;

In your code, you're trying to use the 'use server' directive inside a Client Component (Settings). This is not allowed in Next.js. The 'use server' directive should only be used in Server Components or Server Actions.

In your case, you've correctly defined getUsers as a Server Action in a separate file. However, you're trying to call this Server Action inside a useEffect hook in a Client Component, which is causing the error.

To fix this, you should remove the 'use server' directive from the useEffect hook in your Client Component. Here's how you can refactor your code:

// app/components/Settings.tsx
'use client';

import ThreeColumnInfo from '../components/ThreeColumnInfo';
import UsersTable from '../components/UsersTable';
import PageHeader from '@components/PageHeader';
import TableSearch from '@components/Table/TableSearch';
import Text from '@components/typography/Text';
import ChangeStatus from '@components/Modal/ChangeStatus';

// server actions
import getUsers from '@serverActions/user/getusers';

import { useDebounce } from 'use-debounce';
import { useState, useEffect } from 'react';

function Settings() {
  const [users, setUsers] = useState([]);

  useEffect(() => {
    const fetch = async () => {
      const users = await getUsers();

      setUsers(users);
    };

    fetch();
  }, []);

  return (
    <>
      <PageHeader title="Settings" />
      <ThreeColumnInfo />
      <Text size="lg" weight="semibold" className="mb-30px">
        User Settings
      </Text>

      <UsersTable users={users} />
      {/* <ChangeStatus /> */}
    </>
  );
}

export default Settings;

And your Server Action:

// app/serverActions/getUsers.tsx
'use server';

async function getUsers() {
try {
const res = await fetch(${process.env.NEXTAUTH_URL}/users, {
method: 'GET',
headers: {
'api-secret': ${process.env.NEXT_API_KEY},
'Content-Type': 'application/json',
'Access-Control-Allow-Origin': '*',
},
next: {
tags: ['users'],
},
});

const result = await res.json();

return result;

} catch (error) {
throw new Error('Failed to get users');
}
}
export default getUsers;

For more information, you can refer to the **Next.js documentation on Server Actions** (<https://nextjs.org/docs/app/api-reference/functions/server-actions>).
