5Handling Data I/O in Node.js

Most active web applications and services have a lot of data flowing through them. That data comes in the form of text, JSON strings, binary buffers, and data streams. For that reason, Node.js has many mechanisms built in to support handling the data I/O from system to system. It is important to understand the mechanisms that Node.js provides to implement effective and efficient web applications and services.

This chapter focuses on manipulating JSON data, managing binary data buffers, implementing readable and writable streams, and compressing and decompressing data. You learn how to leverage the Node.js functionality to work with different I/O requirements.

Working with JSON

One of the most common data types ...
