Node.js Stream Pipeline Lab

In this lab, you will work with Node.js streams and use the stream.pipeline() method to build a file-transfer utility. The utility will read a file, compress it using gzip, and then save the compressed result to another file. To achieve this, you will be required to create the necessary Readable, Transform, and Writable streams and combine them using stream.pipeline().

The stream.pipeline() method enables you to compose multiple streams together, ensuring that the final stream is automatically closed regardless of whether an error occurs or not. This method significantly simplifies error handling and helps you write more efficient code when working with the streams. You need Node.js version 14 or higher to use stream.pipeline().

Concepts to Understand

1. Node.js Streams (Readable, Transform, Writable)
2. Using stream.pipeline() method
3. Error handling in Node.js streams

These concepts will help you understand and complete the lab challenges more effectively.
