The JavaScript JSON Cookbook

Chapter 8. Using JSON for Binary Data Transfer

In this chapter, we will discuss the intersection between JSON and binary data. Here, you'll find the following recipes:

• Encoding binary data as a base64 string using Node.js
• Decoding binary data from a base64 string using Node.js
• Encoding and decoding binary data as a base64 string using JavaScript in the browser
• Encoding data as BSON using Json.NET
• Decoding data from BSON using Json.NET
