Kuro is an Electron-based desktop client for Microsoft To-Do that wraps the web interface in a native application shell. It provides desktop-specific features like system tray integration, global keyboard shortcuts, auto-launch capabilities, and theme customization while maintaining compatibility with the Microsoft To-Do web service. The architecture follows a standard Electron pattern with main and renderer processes, using IPC communication for desktop features and electron-store for persistent settings. The application injects custom CSS to theme the Microsoft To-Do interface and adds platform-specific enhancements.
MicroK8s is a lightweight, single-package Kubernetes distribution distributed as a snap. It bundles upstream Kubernetes components (kube-apiserver, kubelet, etcd, containerd, runc, flannel, Calico CNI, dqlite, Helm) into a single snap package with a unified 'kubelite' binary that runs all control plane services as threads. The system provides a CLI (microk8s) with subcommands for cluster management (enable/disable addons, join/leave cluster, status, reset, upgrade), and an addon system that allows installing additional services (e.g., dashboard, ingress, registry) via git-cloned repositories with executable enable/disable hooks. The architecture is a monolith packaged as a snap, with services managed by snap daemons and configuration stored in snap data directories. Key entry points include the snap hooks (configure, install, remove), wrapper scripts in scripts/wrappers/ (enable.py, disable.py, join.py, status.py, etc.), and the kubelite binary. External dependencies include the snap runtime, upstream Kubernetes binaries, containerd, runc, etcd, dqlite, flanneld, and various CNI plugins. The build system uses pinned component versions with patch management for each Kubernetes release, and upgrade scripts handle migrations between versions with rollback support.
fullPage.js is a vanilla JavaScript library for creating full-screen scrolling websites (one-page sites) with vertical/horizontal snap scrolling, sections, and slides. The codebase uses a modular ES6 architecture with separate concerns for scroll handling, mouse/touch input, keyboard navigation, state management, and DOM manipulation. It exports a main class from src/js/fullpage.js with initialization via src/js/app.js. The library manages DOM structure through CSS classes (.fp-section, .fp-slide, .active, .fp-loaded) and maintains global state in src/js/common/state.js. It supports optional jQuery integration via src/js/jquery-adaptor.js and includes polyfills for IE11 compatibility. The build system uses Rollup for bundling and Gulp for asset processing, producing distribution files in dist/. The library features lazy loading for media, responsive breakpoints, and extensive callback hooks for lifecycle management.
ytDownloader is a cross-platform desktop application built with Electron that provides a graphical interface for downloading videos and audio from YouTube and hundreds of other sites using yt-dlp as the backend download engine. It features a comprehensive download manager supporting single downloads, playlists, and YouTube search, with options for format selection, quality, subtitles, compression, and output templates. The application manages its own yt-dlp and ffmpeg binaries, supports auto-updates, and includes a download history with JSON/CSV export, theming, internationalization (23+ languages), system tray integration, and a global hotkey for quick URL pasting. Architecture: The application follows a standard Electron architecture with a main process (main.js) handling window management, IPC handlers, auto-updater, system tray, and global hotkey. A preload script (preload.js) sets up a context bridge (electronAPI) that exposes filesystem operations, process spawning, clipboard access, and other OS services to the renderer. The renderer process consists of several JavaScript modules (src/index.js, src/playlist.js, src/compressor.js, src/preferences.js, src/history_ui.js, src/common.js) that handle specific views. Communication between renderer and main process occurs via Electron's IPC mechanism (ipcRenderer/ipcMain). User preferences are stored in localStorage and a JSON config file, while download history is persisted as JSON. Key entry points: main.js (Electron main process), preload.js (context bridge), html/index.html (single-page UI shell), src/renderer.js (main renderer logic with YtDownloaderApp class), src/index.js (homepage downloader), src/playlist.js (playlist downloader), src/compressor.js (video compressor), src/preferences.js (settings), src/history_ui.js (history view). External dependencies include yt-dlp (download engine), ffmpeg/ffprobe (media processing), Electron (framework), electron-builder (packaging), electron-updater (auto-updates), systeminformation (GPU detection), and SlimSelect (custom dropdowns). The application bundles these binaries or uses system-installed versions, with fallback mechanisms.
