Stream Module

This lesson is part of Node.js · All levels

Summary

Stream allows data to be processed partially so that large files or network data do not need to be loaded entirely into memory. The node provides four types of streams: Readable, Writable, Duplex, and Transform. This concept is the backbone of file operations, HTTP, and interprocess communication.

Key points

There are four types of streams: Readable, Writable, Duplex, and Transform
The stream works with the chunk mechanism so it saves memory
Pipe (stream.pipe) connects the output of one stream to the input stream of another
Key event: data, end, error, and finish
