This is a self-hosted social timeline application (moments/朋友圈) that allows users to post short updates (memos) with rich media: images, videos, music, links, and Douban (Chinese media database) book/movie references. The architecture is a single Go binary that embeds a Nuxt.js static frontend and connects to a SQLite database. The backend provides a REST API with JWT authentication, supports file upload (local or S3), comment system with email notifications, RSS feed generation, and database backup on version changes. Noteworthy features include automatic database backup with cleanup, image thumbnail generation, Google reCAPTCHA integration, and a calendar-based search for memos. The codebase is well-organized with dependency injection (samber/do), proper route grouping, and data migration scripts. The frontend is a Nuxt 3 SPA with Tailwind CSS and component-based UI. The project is actively maintained with frequent commits and a responsive issue tracker.
