how to use the gracefulify function from the fs-extra library in typescript

Here's an example of how to use the gracefulify function from the fs-extra library in TypeScript:

index.ts
import * as fs from 'fs';
import * as gracefulFs from 'graceful-fs';
import { gracefulify } from 'fs-extra';

// Gracefully modify the fs module
gracefulify(fs, gracefulFs);

// Now you can use the fs-extra functions
fs.writeFile('file.txt', 'Hello world!', function (err) {
  if (err) throw err;
  console.log('File created!');
});

In this example, we're importing the fs module and also the graceful-fs module, which is a drop-in replacement for the fs module that provides graceful error handling. We're also importing the gracefulify function from the fs-extra module.

We then call the gracefulify function, passing in the fs module and the graceful-fs module as arguments. This "gracefully modifies" the fs module so that its functions are replaced with versions that use the graceful-fs version that provides graceful error handling.

After this modification, we can use the fs-extra functions as normal, as shown in the example with fs.writeFile.
