This is a standalone web UI for Midjourney image generation, built as a Next.js 14 application. It provides a prompt editor, image preview with upscale/variant/reroll actions, a task history list, and settings to configure a midjourney-proxy service. The app can run standalone or be embedded as a LobeChat plugin via an iframe. It uses React with Zustand for state management, SWR for data fetching, Immer for immutable state updates, and antd-style for theming. The backend consists of two API routes: one proxies requests to the midjourney-proxy service, and another uploads images to Imgur. The codebase is well-structured with clean separation of concerns, i18n support, and responsive design. While the application is functionally straightforward, it demonstrates solid engineering practices including pure reducer functions with unit tests, typed state management, and a modular layout system.
