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
