Stb (εΎεΊ) is a full-stack image hosting service built as a pnpm monorepo. The backend is a Node.js/Express application with MongoDB (Mongoose) providing REST APIs for user authentication, image upload, album management, admin operations, and system configuration. The frontend is a Vue 3 single-page application using Pinia for state management, Vue Router with lazy-loaded views, and a mix of Ant Design Vue and Element Plus UI libraries. The system supports multiple storage backends (local filesystem, S3-compatible, Alibaba OSS, Tencent COS, Qiniu, Upyun, SFTP, FTP, WebDAV, Telegram, GitHub) via a pluggable adapter pattern, and integrates AI-based content moderation (Tencent, Aliyun, NSFWJS). Deployment is Docker-based with a multi-stage build and GitHub Actions CI/CD for multi-architecture images. The application includes a comprehensive admin panel for user, image, log, album, role group, invite code, and configuration management, as well as OAuth login (GitHub, Google, Linux DO), email verification, and a slider captcha component. While the codebase is functional and well-structured with clear separation of concerns, it exhibits some technical debt: mixed UI libraries increase bundle size, the configuration view is monolithic and exposes sensitive credentials to the client, there are no automated tests, and some patterns (e.g., IP detection, Docker entrypoint sed) are fragile. Overall, it is a solid, production-ready image hosting solution with reusable utility modules.
