What is the pipeline method in Node.js streams?

The pipeline method in Node.js streams is a utility that allows you to connect multiple stream operations together, making it easier to handle data flow.

Can you give me an example of how to use the pipeline method?

Sure! Here's a simple example:

const { pipeline } = require('stream');
const fs = require('fs');

pipeline(
  fs.createReadStream('input.txt'),
  fs.createWriteStream('output.txt'),
  (err) => {
    if (err) {
      console.error('Pipeline failed.', err);
    } else {
      console.log('Pipeline succeeded.');
    }
  }
);

What happens if one of the streams fails?

If one of the streams fails, the callback function provided to the pipeline will be called with the error, allowing you to handle it appropriately.

Are there any performance benefits to using the pipeline method?

Yes, using the pipeline method can improve performance by managing backpressure automatically and ensuring that streams are properly closed.
