DeepSeek Harness Desktop

English · 简体中文

A lightweight Windows desktop built with [Tauri 2](https://tauri.app) that launches the locally installed [DeepSeek Harness](https://www.npmjs.com/package/@deepseek-ai/dsh) and shows its original web UI. It does not patch, copy, or rebuild DSH.

Project Motivation

This project is intended for people who are not familiar with command-line tools, Node.js, or local web-service setup. It provides a ready-to-use Windows desktop entry point that lowers the barrier to installing and using DeepSeek Harness.

This project is a non-invasive desktop host, not a modified distribution of DSH. It does not alter DSH source code, installed files, or runtime code; inject patches; copy DSH; or repackage it. The app only uses the public dsh and npm commands to check the environment, install or update the official package, verify versions, start the local service, and manage the DSH child process it started. On uninstall, the global npm package is removed only when the app can confirm that it originally installed DSH automatically; independently installed copies are left untouched.

Features

• Checks the runtime environment (WebView2, Node.js, dsh) before starting
• Installs dsh automatically via npm when missing (npmmirror registry)
• Runs dsh web --host 127.0.0.1 --port 0 and waits for the reported local URL
• Prompts for an in-app upgrade when a new DSH version is available
• Terminates the whole DSH process tree when the window is closed

Requirements

Dependency	Notes
Windows 10/11	Windows only
Microsoft Edge WebView2 Runtime	Bootstrapped by the installer when missing
Node.js	Must be available on PATH
DeepSeek Harness (dsh)	Installed globally, dsh --version works

Install

Download the latest installer from the Releases page and run it.

Build from Source

npm install
npm run tauri build

The installer is generated at src-tauri/target/release/bundle/nsis/.

Each npm run tauri build bumps the patch version automatically, synced across package.json, package-lock.json, src-tauri/tauri.conf.json, and src-tauri/Cargo.toml:

npm run tauri build            # 0.1.1 → 0.1.2 → 0.1.3 …
npm run tauri build -- minor   # 0.1.x → 0.2.0
npm run tauri build -- major   # 0.x.y → 1.0.0

npm run tauri dev and other tauri commands never touch the version.

How It Works

1. Checks WebView2, Node.js, and the dsh CLI in sequence.
2. Installs dsh via npm if it is missing.
3. Runs dsh web --host 127.0.0.1 --port 0 and parses the local URL from its output.
4. Verifies the TCP port is reachable, then navigates the window to the DSH UI.
5. Terminates the DSH process tree when the app exits.
