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

#

Based on the information provided in the extracts, it seems you are trying to implement a debounced search functionality in your Next.js application. The useDebounce hook is used to delay the processing of the input value to limit the number of requests made to the server.

In your code, you are using useDebounce on listOfUsers which is the state that holds the list of users. However, you should use useDebounce on the search input value instead. Here's how you can do it:

'use client';

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

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

// server action
import searchUser from '@serverActions/user/searchUser';

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

type Props = {
  users: UserType[];
};

function UsersTable({ users }: Props) {
  const [listOfUsers, setListOfUsers] = useState<UserType[] | []>(users);
  const [inputValue, setInputValue] = useState('');
  const [debouncedValue] = useDebounce(inputValue, 1000);

  useEffect(() => {
    if (debouncedValue) {
      handleSearchInput(debouncedValue);
    }
  }, [debouncedValue]);

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

    setListOfUsers(data);
  };

  return (
    <>
      <TableSearch
        title="LIST OF USERS"
        buttonTitle="Add User"
        url="settings/create-user"
        handleSearchInput={(e) => setInputValue(e.target.value)}
      />
      <div className="text-left">
        <Suspense fallback={<p>Loading...</p>}>
          <Table users={listOfUsers} />
        </Suspense>
      </div>
    </>
  );
}

export default UsersTable;
#

In this code, useDebounce is used on the inputValue state. When the input value changes, it waits for 1000ms (1 second) before updating debouncedValue. The useEffect hook listens for changes in debouncedValue and calls handleSearchInput when it changes.

Please note that this code is based on the assumption that your TableSearch component calls handleSearchInput with the event object from the input field. If it only passes the input value, you can remove e.target.value from setInputValue(e.target.value).

This code is not directly extracted from the provided extracts but is based on the general usage of the useDebounce hook in React applications. For more specific information about Next.js, you can refer to the official Next.js documentation (https://nextjs.org/docs).

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

The error TypeError: Cannot read properties of undefined (reading 'value') typically occurs when you're trying to access a property of an object that is undefined.

In the context of your Next.js application, this could be happening due to a variety of reasons. It could be that a component's props, state, or context is undefined when you're trying to access it, or it could be a response from an API that is not structured as expected.

Unfortunately, the provided extracts do not contain specific information about this error in the context of your code. To debug this issue, you can:

  1. Check the line of code where the error is occurring. This should be indicated in the error message.
  2. Verify that the object you're trying to access the property from is not undefined.
  3. If the object is coming from props, state, or context, ensure that it is initialized correctly.
  4. If the object is a response from an API, ensure that the API is returning the expected data.

For more specific information about handling errors in Next.js, you can refer to the official Next.js documentation (https://nextjs.org/docs/basic-features/error-handling).

@drowsy blaze when to use server-action

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

#

Server actions in Next.js are typically used when you need to perform operations that involve server-side data fetching, manipulation, or other server-side logic. They are often used in conjunction with Next.js's data fetching methods like getServerSideProps or getStaticProps.

In the provided extracts, server actions are used for data fetching. For example, in the UsersTable component, the searchUser server action is used to fetch user data based on the search input:

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

In this case, searchUser is a server action that fetches user data from the server. This data is then used to update the listOfUsers state in the UsersTable component.

Server actions are particularly useful in scenarios where:

  • You need to fetch data from a server-side database or API.
  • You need to perform server-side computations that should not be done on the client side for performance or security reasons.
  • You need to access sensitive data or perform actions that should not be exposed to the client side, such as accessing API keys or performing authentication.

For more information on server actions and data fetching in Next.js, you can refer to the official Next.js documentation (https://nextjs.org/docs/basic-features/data-fetching).

The use server directive in Next.js is used to ensure that a function or a file is only ever executed on the server. However, it's important to note that useEffect is a React Hook that is specifically designed to run side effects on the client side, and it cannot be used within Server Components.

In the provided extracts, there's an example of how to use the use server directive in a server action:

// app/page.js
export default function ServerComponent() {
 async function myAction() {
 'use server'
 // ...
 }
}

In this example, the use server directive is used at the top of the myAction function body to ensure that this function is only ever executed on the server.

If you need to perform server-side logic in a component, you should use server actions or server components instead of trying to use useEffect with the use server directive.

For more information on server actions and server components in Next.js, you can refer to the official Next.js documentation (https://nextjs.org/docs/app/api-reference/functions/server-actions).

The NEXTAUTH_URL is an environment variable used by NextAuth.js for configuration. If it's returning undefined, it could be due to a few reasons:

  1. The variable is not correctly defined in your .env file.
  2. The .env file is not being loaded correctly.
  3. The variable is not being accessed correctly in your code.

Here are some steps you can take to troubleshoot:

  1. Ensure that NEXTAUTH_URL is defined in your .env file and that the file is located in the root of your project. The variable should be defined like this: NEXTAUTH_URL=<http://localhost:3000.>

  2. Make sure you're restarting your development server after making changes to your .env file. Changes to environment variables won't take effect until the server is restarted.

  3. If you're trying to access NEXTAUTH_URL in your client-side code, you'll need to prefix it with NEXT_PUBLIC_ to expose it to the browser. However, be aware that this will expose the variable to anyone who can access your site, so it should only be used for public values.

  4. If you're using Vercel for deployment, you'll need to add your environment variables to your project settings on the Vercel dashboard.

If you're still having issues, please refer to the Next.js documentation on environment variables (https://nextjs.org/docs/basic-features/environment-variables) and the NextAuth.js documentation (https://next-auth.js.org/configuration/options#nextauth_url) for more information.
