This project is a Node.js library for Base64 encoding, decoding, escaping, and unescaping strings for URL applications. It provides a simple API for developers working with Base64 data in web contexts, particularly those needing URL-safe Base64 transformations. The library is designed for Node.js developers who need to handle Base64 operations in URL contexts, offering both standard Base64 functionality and URL-specific escaping/unescaping methods.
