Base64 encoding allows us to transform binary data into text data. The reasons for this are rooted in the history of network protocols, but it is still a widely used form of encoding when shipping binary data.

In these recipes, we will see how to encode and decode binary and base64-encoded files.

Encoding a string as base64

Node provides a string Buffer class that can represent text data in a variety of encodings, including ASCII, UTF-8, and Base-64. This Buffer class will be the core of our conversion operations.

Getting ready

Node supports base64 encoding without the need of an external module. We will be using Node's built-in capabilities.

How to do it...
