btoa-lite

btoa-lite provides a lightweight, isomorphic `btoa` (Base64 encoding) implementation for both Node.js and browser environments. Its primary differentiator is its approach to environment-specific code loading, utilizing `package.json`'s `main` and `browser` fields to avoid bundling Browserify's potentially large `Buffer` shim into browser builds. This ensures minimal bundle sizes for browser targets while providing a functional Base64 encoder in Node.js using its native `Buffer` API. As of version 1.0.0, it is a stable, mature package, likely in a maintenance state given its last publish in 2016, with a focus on simplicity over frequent feature updates. It aims to be the smallest and simplest means for `btoa` functionality across environments.
