This repository implements a Linux desktop GUI for managing WireGuard VPN profiles. It is built using the Tauri v2 framework, combining a Rust backend for system-level operations (connection management, encryption, file I/O) with a Next.js 16 (React 19) frontend for the user interface. The application allows users to create, import, export, connect, and disconnect WireGuard tunnels, and provides optional at-rest encryption for profile data using a user-defined PIN. The architecture follows a clean IPC-based separation of concerns. The frontend communicates with the Rust backend exclusively through typed Tauri commands defined in `lib/effects.ts`. The backend in `src-tauri/src/main.rs` manages application state, executes WireGuard commands via shell scripts (`wg.sh`), and handles encryption via a dedicated security module. The UI is built from a comprehensive library of ~40+ composable, accessible components in `components/ui/`, demonstrating a strong commitment to frontend architecture and design system principles. The most reusable assets are the Rust security module (`security.rs`), which implements PIN-based encryption using Argon2id and XChaCha20-Poly1305 in a self-contained manner, and the typed IPC service layer (`lib/effects.ts`), which cleanly decouples the UI from the backend. The UI component library, while styled for this project, follows an architectural pattern (atomic, composable primitives) that is directly transferable to other React projects. The project is actively maintained with CI/CD, E2E testing, and semantic versioning, though it carries some technical drift in its Nix build configuration (targeting Tauri v1) and deprecated plugin permissions.
