5. Handling Data I/O in Node.js
Most active web applications and services have a lot of data flowing through them—in the form of text, JSON strings, binary buffers, and data streams. Therefore, Node.js has a lot of mechanisms built into it 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, and implementing readable and writable streams and data compression/decompression. You will learn how to leverage the Node.js functionality to work with different I/O requirements.
