After installing the package, you can import the createreadstream function into your JavaScript file using the require() function. Here's an example of how you can use the createreadstream function to read a file:

index.tsx
const fs = require('fs-extra');

// create a read stream for the file
const stream = fs.createReadStream('path/to/file');

// handle stream events
stream.on('open', () => {
  console.log('Stream opened');
});

stream.on('data', (data) => {
  console.log(`Received ${data.length} bytes of data`);
});

stream.on('error', (err) => {
  console.error(`An error occurred: ${err.message}`);
});

stream.on('close', () => {
  console.log('Stream closed');
});

In this example, we first import the fs-extra package and create a read stream for a file by calling the createReadStream() function with the file path as its argument. We then set up event listeners for the stream to handle different events that may occur.

When the 'open' event is emitted, we log a message to the console. When the 'data' event is emitted, we log the length of the received data to the console. When the 'error' event is emitted, we log the error message to the console. Finally, when the 'close' event is emitted, we log a message to the console to indicate that the stream has been closed.
