uppie

uppie is a lightweight JavaScript library that provides a consistent, cross-browser API for directory and multi-file uploads, solving the long-standing fragmentation between browsers like Chrome, Firefox, and Safari. It is built for web developers who need to handle complex file selection (including folders) without wrestling with browser-specific quirks or deprecated APIs. Its interest lies in offering a drop-in, dependency-free solution that normalizes upload behavior, making it a practical devtool for modern web applications.
