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

To use the createWriteStream function from fs-extra module in node.js, first, you need to require the module as follows:

index.tsx
const fs = require('fs-extra');
32 chars
2 lines

Then, you can use the createWriteStream function to create a writable stream to a file. Here's an example:

index.tsx
const writeStream = fs.createWriteStream('/path/to/file.txt');

writeStream.write('Hello World!', 'utf-8'); // Add data to the stream
writeStream.end(); // Close the stream
173 chars
5 lines

In this example, we create a writable stream to a file located at /path/to/file.txt. We then write the data "Hello World!" to the stream using the write function and specify the encoding as utf-8. Finally, we close the stream using the end function.

You can also listen to events on the stream to know when the write operation has completed, like this:

index.tsx
writeStream.on('finish', () => {
  console.log('Write operation completed successfully');
});
94 chars
4 lines

This code will print a message to the console when the write operation has completed.

That's how you can use the createWriteStream function from fs-extra to write to a file in node.js.
