make component that pulls data from an external json file and loops over data in next js
user
sure! to create a component that pulls data from an external json file, you can follow these steps:

1. create a new component in next.js by running the following command:
```bash
npx create-next-app my-app
```
1. change to your new project directory:
```bash
cd my-app
```
1. create a json file for the data that the component will pull from. for example, create a file named `data.json` with the following content:
```json
{
  "users": [
    {
      "id": 1,
      "name": "john doe",
      "email": "johndoe@example.com",
      "isactive": true
    },
    {
      "id": 2,
      "name": "jane smith",
      "email": "janesmith@example.com",
      "isactive": false
    },
    // more users
  ]
}
```
1. in your project root, you can create a folder named `components`. inside the `components` folder, create a new file named `scandata.js` for the new component.
```bash
mkdir components
touch components/scandata.js
```
1. now, you can create the `scandata` component in `scandata.js`. you'll want to use the `fetch` api to retrieve the data from your `data.json` file:
```javascript
import react, { useeffect, usestate } from 'react';

const scandata = () => {
  const [users, setusers] = usestate([]);

  useeffect(() => {
    // fetch data from the external json file
    fetch('data.json')
      .then((res) => res.json())
      .then((data) => {
        setusers(data.users);
      });
  }, []);

  return (
    <div>
      <h2>scan data</h2>
      <ul>
        {users.map((user) => (
          <li key={user.id}>
            {user.name} - {user.email}
          </li>
        ))}
      </ul>
    </div>
  );
};

export default scandata;
```
in the above code, we're importing the `fetch` function from the `fetch` package in order to retrieve the json data from `data.json`. we're storing the returned json data in `users` state, which is represented as an array of objects. we're then rendering all of the `users` in an unordered list (`<ul>`) using destructuring assignment to easily render the user data.

1. lastly, you can use the `scandata` component in your `pages/index.js` page like this:
```javascript
import react from 'react';
import scandata from '../components/scandata';

export default function home() {
  return (
    <div>
      <h1>welcome to my website!</h1>
      <scandata />
    </div>
  );
}
```
this will render the `scandata` component in your `home` page, showing the data from the `data.json` file.

please note that you will need to have the `fetch` package installed in your node.js project in order for the above code to work. you can install it using the following command:
```bash
npm install fetch
```

      });
