Reactjs – Where is ProgressBar component defined in this react-papaparse example?

I was trying react-papaparse examples from the documentation: https://react-papaparse.js.org/docs

Can someone explain where is ProgressBar defined?
The code tested is here: https://github.com/Bunlong/react-papaparse/blob/v4.0.0/examples/CSVReaderBasicUpload.tsx

<CSVReader
  onUploadAccepted={(results: any) => {
    console.log('---------------------------');
    console.log(results);
    console.log('---------------------------');
  }}
>
  {({
    getRootProps,
    acceptedFile,
    ProgressBar,
    getRemoveFileProps,
  }: any) => (
    <>
      <div style={styles.csvReader}>
        <button type='button' {...getRootProps()} style={styles.browseFile}>
          Browse file
        </button>
        <div style={styles.acceptedFile}>
          {acceptedFile && acceptedFile.name}
        </div>
        <button {...getRemoveFileProps()} style={styles.remove}>
          Remove
        </button>
      </div>
      <ProgressBar style={styles.progressBarBackgroundColor} />
    </>
  )}
</CSVReader>

I have tried to use Visual Code to trace back to the definition, but nothing.
Where can I see what is the component doing?

    In the react-papaparse library, there is no built-in ProgressBar component provided. The react-papaparse library focuses on parsing CSV data in React applications and does not include a progress bar implementation.

    If you have come across an example that shows a ProgressBar component while using react-papaparse, it is likely that the ProgressBar component is defined separately or provided by another library or custom implementation specific to that example.

    To add a progress bar to your react-papaparse implementation, you would need to integrate a separate progress bar library or create a custom progress bar component in your application. There are several popular progress bar libraries available for React, such as react-progressbar.js, react-top-loading-bar, or react-bootstrap ProgressBar. You can choose one of these libraries or create your own progress bar component based on your specific requirements.

    Remember to refer to the documentation and examples provided by the selected progress bar library for instructions on integrating it with your React application and updating the progress based on the progress events emitted by react-papaparse.

    in the given code snippet, the ProgressBar component is being used within the csvreader component. However, the provided code does not explicitly define the ProgressBar component. it seems that you are using a third-party library for CSV file handling, which includes the csvreader component and provides the progressBar component as part of its functionality. To understand the behavior and usage of the progressBar component, you should consult the documentation or source code of the library you are using.

    You can try following code if it’s working for progressbar using react-papaparse library

      import React, { CSSProperties } from 'react';
import { useCSVReader } from 'react-papaparse';

const styles = {
  //styles...
};

export default function CSVReader() {
  const { CSVReader, progress } = useCSVReader();

  return (
    <CSVReader
      onUploadAccepted={(results: any) => {
        console.log('---------------------------');
        console.log(results);
        console.log('---------------------------');
      }}
    >
      {({
        getRootProps,
        acceptedFile,
        getProgressBarProps,
        getRemoveFileProps,
      }: any) => (
        <>
          <div style={styles.csvReader}>
            <button type="button" {...getRootProps()} style={styles.browseFile}>
              Browse file
            </button>
            <div style={styles.acceptedFile}>
              {acceptedFile && acceptedFile.name}
            </div>
            <button {...getRemoveFileProps()} style={styles.remove}>
              Remove
            </button>
          </div>
          <div style={styles.progressBarBackgroundColor}>
            <ProgressBar {...getProgressBarProps()} />
          </div>
        </>
      )}
    </CSVReader>
  );
}
