## Introduction

DevNexus is a **cross-platform desktop application** that integrates everyday developer environment management tasks into a lightweight GUI:

- **Software Center** — Visual management of system packages (brew / apt / winget / choco / pip / npm)

- **Environment Manager** — Edit PATH, environment variables, dotfile configurations

- **Terminal Core** — Embedded PTY terminal with real shell sessions

- **Mirror Settings** — One-click configuration for pip / npm / apt mirror sources

- **System Dashboard** — Real-time CPU, memory, disk, and runtime version monitoring

- **Global Settings** — App preferences and theme management

Only **~10MB** installation, **~60MB** memory usage — say goodbye to Electron bloat.

## Why DevNexus?

Developers face these fragmented tools every day:

| Task | Current Solutions | Problems |

|---|---|---|

| Install dev tools | `brew install` / `apt install` / `winget` | Different commands per platform, no unified view |

| Manage SDK versions | nvm / pyenv / asdf / sdkman | CLI-only, poor Windows support |

| Switch env variables | Manually edit `.bashrc` / `.zshrc` | Error-prone, no visualization |

| Configure mirrors | Look up docs separately | Tedious, hard to remember |

| View system info | `htop` / `df` / `node -v` everywhere | No centralized panel |

**DevNexus integrates all of this into a single GUI.** No need to memorize commands or switch between tools.

| **Stack** | Tauri+Svelte+Rust | Tauri+React+Rust | Go | Go | Tauri+React+Rust | Tauri+React+Rust |

**Key Differences:**

- **nvm-desktop** — Only manages Node.js versions, limited scope

- **VMR / vfox** — Powerful but pure CLI/TUI, no visual interface

- **DevTool Manager** — Only manages npm/cargo/pip global packages, no system-level env or terminal

- **DevTools-X** — Developer utility collection (JSON formatter, JWT parser, etc.), not an environment manager

- **DevNexus** — **The only project that integrates system package management + multi-runtime versions + env variables + terminal + mirror config into one GUI**

### Tech Stack

| Layer | Technology | Description |

|---|---|---|

| **Desktop Framework** | [Tauri 2.0](https://tauri.app/) | Native system Webview, not Electron |

| **Frontend** | [Svelte 5](https://svelte.dev/) | Compile-time framework, only ~2KB runtime |

| **Styling** | [Tailwind CSS](https://tailwindcss.com/) | Utility-first CSS |

| **Terminal** | [xterm.js](https://xtermjs.org/) | Web terminal rendering |

| **Backend Language** | [Rust](https://www.rust-lang.org/) | System calls, performance, memory safety |

| **PTY** | [portable-pty](https://crates.io/crates/portable-pty) | Cross-platform terminal backend |

| **Async Runtime** | [tokio](https://crates.io/crates/tokio) | Rust async I/O |

| **System Info** | [sysinfo](https://crates.io/crates/sysinfo) | CPU/Memory/Disk/Process |

| **Executable Lookup** | [which](https://crates.io/crates/which) | Cross-platform PATH lookup |

| **Serialization** | [serde](https://crates.io/crates/serde) | JSON/TOML config read/write |

### Why This Stack?

- **Tauri over Electron** — 10MB vs 150MB install, 60MB vs 300MB memory, uses system Webview instead of bundled Chromium

- **Svelte over React** — Compile-time elimination of framework runtime, smaller output; native HTML syntax, zero-cost migration from design prototypes

- **Rust over Node.js** — Native system call capabilities, `portable-pty` is the most mature cross-platform PTY solution, memory safe
