stream.Writable.uncork() Lab

0.0% Acceptance

In this lab, you will explore the stream.Writable.uncork() method in Node.js. The uncork() method is used in Writable streams to release the internal buffer when it forms a queue to improve the overall throughput of the stream. Throughout the lab, we will dive deeper into how to use uncork() effectively with the stream data.

By the end of this lab, you should have a better understanding of the following concepts:

  • Writable Streams in Node.js
  • The stream.Writable.uncork() method
  • Proper usage of uncork() in different scenarios


  1. Create a Writable stream
  2. Implement the _write method of the stream
  3. Write data to the stream
  4. Use cork() and uncork() method to control data flow
  5. Add a custom listener to track buffer draining

Good luck in exploring and understanding the stream.Writable.uncork() method!
