Node-RED Base64 Converter Node

This package provides a Node-RED node for encoding and decoding messages using Base64 format. It allows developers to convert `msg.payload` to a Base64 string if the input is a binary buffer, or decode a Base64 string back into a binary buffer. As of its stable `1.0.0` release, it offers robust and straightforward functionality for common Base64 transformations within Node-RED flows. Being part of the official Node-RED nodes collection, it often aligns with Node-RED core updates and feature milestones. Its primary differentiator is its seamless integration into the visual flow programming paradigm of Node-RED, handling the technical details of buffer and string conversions automatically based on input type. The package is maintained, indicating stability with less frequent, but impactful, updates. Its purpose is to simplify Base64 operations for Node-RED users without requiring custom function nodes.
