WebDrop is a peer-to-peer file and message sharing web application built with Vue.js that enables direct device-to-device transfers without installation. It uses WebRTC via the P2PT library for peer discovery and communication, simple-peer-files for file transfers, and Vuex for state management. The application features automatic LAN device discovery, internet sharing via room codes, resume capability for interrupted transfers, and a responsive UI with multiple views for managing files, messages, and connected devices. The architecture follows Vue.js best practices with clear separation between components, state management, and routing.
