how to use the writefile function from fs-extra in javascript

The writefile function from the fs-extra module in Node.js allows us to write data to a file. It takes three arguments: the file path, the data to write, and a callback function. Here's an example of how to use it:

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

const filePath = 'path/to/file.txt';
const data = 'Hello, world!';

// Write to file asynchronously
fse.writeFile(filePath, data, (err) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Data written to file successfully');
  }
});

In the above code, we first import the fs-extra module using the require function. We then define the file path and data we want to write to the file. Finally, we call the writeFile function, passing in the file path, data, and a callback function.

The callback function is called once the data is written to the file. It takes an error argument, which is null if there was no error. If there was an error, we log it to the console; otherwise, we log a success message.

Note that the writeFile function is asynchronous, meaning that it doesn't block the main thread while writing to the file. If you want to perform other operations after the data has been written, you'll need to do so within the callback function.
