dsh-desktop-window

中文 | English

DSH desktop-window plugin: opens the DeepSeek Harness Web UI in a standalone app window (Edge/Chrome --app mode) — double-click to launch, auto-popup, no address bar, fully isolated from your everyday browser.

Features

• Auto-open: once dsh web boots and the server is ready, a standalone app window pops up automatically (enabled by default);
• Manual toggle: an "独立窗口" (Standalone Window) button in the session header action row opens/closes the window;
• Settings toggle: Settings → General → "启动时自动打开独立窗口" (auto-open at startup), persisted to $DSH_HOME/desktop-window.json (BOM-tolerant, so Notepad edits are safe);
• Whale icon: injects the official DeepSeek whale favicon (16/32/64/128/256) plus a web manifest (192/512) — the window title bar shows the whale; the taskbar icon is best-effort via an icon helper (see Known limitations);
• Security: mutation routes are same-origin guarded (cross-site POST → 403); the window uses a dedicated profile directory under TEMP, fully isolated from your normal Edge/Chrome profile;
• Lifecycle: window-close state syncs automatically; on plugin unload the window process tree, icon helper and all routes are cleaned up.

Installation

Prerequisites: DSH installed (dsh on PATH) and pnpm (dsh plugin shells out to pnpm; npm install -g pnpm if missing).

From GitHub (recommended):

dsh plugin --profile web add github:<your-name>/dsh-desktop-window
# or
dsh plugin --profile web add "git+https://github.com/<your-name>/dsh-desktop-window.git"

From a local directory:

dsh plugin --profile web add "file:D:/path/to/dsh-desktop-window"

Windows path-with-spaces gotcha: dsh plugin forwards arguments to pnpm through a shell, and paths
containing spaces get re-split, producing ERR_PNPM_SPEC_NOT_SUPPORTED_BY_ANY_RESOLVER.
Workaround: create a space-free junction and install from there:

New-Item -ItemType Junction -Path D:\dsh-desktop-window -Target 'D:\path with spaces\dsh-desktop-window'
dsh plugin --profile web add "file:D:/dsh-desktop-window"

dsh plugin add installs the package into the profile's node_modules and automatically merges the
dsh.bundle-declaring package into dsh.profile.bundles — no manual config edits. Restart dsh web after installing.

Updating

# update to the latest release (git deps re-fetch the default branch HEAD)
dsh plugin --profile web update dsh-desktop-window

# then restart dsh web

Release process: see CHANGELOG.md. Users never need to re-add; a plain update is enough.

Usage

dsh web
# a standalone app window pops up once the server is ready

• "独立窗口" button in the session header: open/close the window;
• Settings → General: turn auto-open on/off;
• Browser choice: Edge first, Chrome as fallback (both use the --app window mode with identical flags).
  To change the preference order, edit BROWSER_CANDIDATES in lib/index.js.

Desktop shortcut (Windows)

One-liner (targets DSH-Desktop.cmd, whale icon):

powershell -ExecutionPolicy Bypass -File "<plugin-dir>\scripts\create-shortcut.ps1"
# with a default workspace:
powershell -ExecutionPolicy Bypass -File "<plugin-dir>\scripts\create-shortcut.ps1" -WorkspaceDir "D:\my project"

You can also just double-click DSH-Desktop.cmd (uses the global dsh when present, falls back to npx).

Platforms

Windows first (window-close relies on taskkill; the taskbar icon helper relies on PowerShell). On
macOS/Linux auto-open and the button work, but closing degrades to killing the main process only.

Development & build

lib/client.js is the browser-side bundle (the built artifact is committed, so installers never build). Two rules matter:

• react must stay external: official client bundles require("react") against the module-table seed word
  (the shared React registered by the shell kernel); bundling it in creates a second React and breaks Hooks;
• the __ModuleLoader__.load registration shell is mandatory: bare CJS output is not recognized by the module table.

Rebuild:

npm install          # esbuild + react (dev deps)
npm run build        # node scripts/build-client.js

Layout

package.json             dual-face declaration (dsh.bundle + dsh.client)
cordis.patch.yml         composition layer (one row: desktop-window)
lib/index.js             Host half: window process + HTTP routes + icon/manifest injection + state persistence
lib/client.js            browser bundle (built artifact, committed)
src/client.js            client source (React)
scripts/build-client.js  build script (esbuild + registration shell)
scripts/set-window-icon.ps1  taskbar icon helper (WM_SETICON + custom AppUserModelID)
scripts/install.ps1      one-shot installer
scripts/create-shortcut.ps1   one-shot desktop shortcut
DSH-Desktop.cmd          double-click launcher
assets/                  official DeepSeek whale icon (SVG / multi-size PNG / ICO)

Known limitations

• Windows taskbar button icon: the title bar shows the whale (favicon/manifest take effect), but the taskbar
  button still shows the default icon on some Edge versions — the helper tries WM_SETICON + a custom
  AppUserModelID with varying success. For a guaranteed whale taskbar icon, use "Edge menu → Apps → Install
  this site as an app" once (it consumes the manifest this plugin injects).
• Closing the app window does not quit the dsh process (by design: only the standalone window closes).
• The auto-open toggle lives in $DSH_HOME/desktop-window.json; a future version may migrate it to the settings service.
