jQuery File Upload is a mature, feature-rich jQuery plugin for handling file uploads in web browsers. It provides multiple file selection, drag & drop support, progress bars, client-side image resizing, preview functionality, and supports cross-domain, chunked, and resumable uploads. The architecture follows jQuery widget patterns with a modular plugin system that separates concerns into core functionality, processing pipelines, media handling, validation, UI components, and transport mechanisms. The code demonstrates sophisticated handling of browser inconsistencies and edge cases while maintaining a clean, extensible design.
FileCodeBox is a file and text sharing service built with FastAPI and Tortoise ORM. It allows users to upload files or text accessible via short codes, with features including time/count-based expiration, chunked uploads, pre-signed URLs for direct cloud storage uploads, and an admin dashboard for management. The architecture uses a modular design with separate apps for base functionality and admin, storage abstraction for multiple backends (local, S3, OneDrive, WebDAV, OpenDAL), and background tasks for cleanup. Key entry points include main.py (FastAPI setup), apps/base/views.py (public sharing endpoints), and apps/admin/views.py (admin interfaces). The service demonstrates solid engineering practices with reusable components like storage abstraction and security headers, though some areas like settings management and rate limiting show opportunities for improvement in distributed environments.
