Overview of this book

If you're writing applications that move structured data from one place to another, this book is for you. This is especially true if you've been using XML to do the job because it's entirely possible that you could do much of the same work with less code and less data overhead in JSON. While the book's chapters make some distinction between the client and server sides of an application, it doesn't matter if you're a frontend, backend, or full-stack developer. The principles behind using JSON apply to both the client and the server, and in fact, developers who understand both sides of the equation generally craft the best applications.

Introduction


There are typically two reasons why you might want to think about binary representation when using JSON: either because you need to carry binary data between one part of your application to another or because you're worried about the size of the JSON you're transporting.

In the first case, you're actually a little stuck, as the existing JSON specification doesn't provide a container format for binary data because JSON is a text-based representation of data at its heart. You can choose to encode binary data in another format, such as base64, which renders binary data as a printable character string, or you can use an extension of JSON, such as Binary JSON (BSON), that supports Binary data.

BSON uses the semantics of JSON but represents the data in a binary form. Thus, the same basic structure is available: a (possibly nested) map of key-value pairs, where values can be other key-value pairs, arrays, strings, or even binary data. However, instead of using plaintext encoding, the...
