This repository is a comprehensive frontend visual effects collection and demonstration platform. It contains over 100 self-contained demos and tools covering CSS animations, Canvas 2D/WebGL effects, Three.js 3D scenes, ECharts data visualizations, AI/ML integrations (TensorFlow.js for pose detection and body segmentation, MediaPipe, Tesseract.js OCR), and client-side media processing (image, video, PDF). The architecture is a React 18 single-page application (SPA) using TypeScript, Webpack 5, Ant Design, and react-intl for internationalization. All processing occurs entirely in the browser; there is no backend or persistent data store. The project serves as both a personal portfolio and a learning resource for advanced frontend techniques, but it is not a single-purpose production application. The code quality varies widely: some components demonstrate high craftsmanship (e.g., custom PNG encoder, image manipulation utilities, cross-page communication hook), while many others are boilerplate-heavy duplicates or exploratory demos. No automated tests are present, and the build output includes large minified chunks alongside source code, creating maintenance overhead.
