A self-contained Hono application that mounts a complete REST-style mock API (user, dashboard, table, notices, geographic, list, profile, monitor routes) with CORS handling and error routes. It is isolated in its own package and can be extracted as a starter for any Cloudflare Workers API or as a production mock backend.

A React class component that catches render errors and specifically handles dynamic import failures from route-level code splitting, offering retry/reload UI. It is dependency-light and can be dropped into any React application to improve resilience during deployment and chunk loading.

A small connectivity-aware banner built on React's useSyncExternalStore hook. It monitors browser online/offline state in a framework-correct way and renders a dismissible notice. This is an easily extractable pattern for any React app needing offline or network-status UI.

A custom Webpack loader that imports markdown files as raw strings, enabling documentation and cheatsheets to be embedded directly into bundled output without runtime fetch calls. It is a self-contained utility that solves a recurring build problem and can be reused in any Webpack-based project.

A compound component in the style of Select/Option, exposing TagSelect and TagSelect.Option for multi-select tag filtering. It encapsulates expandable tag lists and selection state while remaining UI-only and loosely coupled, making it a reusable filtering primitive for list or dashboard pages.
