dsh-open-deepseek-web

A sidebar button for the DSH Web UI that opens chat.deepseek.com in a standalone Chrome app window — and, when that window is already open, brings it back to the front instead of opening a second one.

DSH 侧边栏的一个「网页版」按钮：点一下用 Chrome 应用窗口打开 chat.deepseek.com；已经开着，就把那个窗口还原并置顶，不重开、不刷新。

What it does / 它做什么

• Focus instead of relaunch / 聚焦而不是重开 — the host half enumerates visible top-level windows and looks for a title containing deepseek but not Harness. A match is restored and raised; no match falls through to a launch.
• Chrome app mode / 应用窗口 — launches chrome --app=https://chat.deepseek.com, which reuses the default Chrome profile, so the DeepSeek account is the one already signed in in your browser.
• Back to the conversation / 点完就回 — the main-panel component asks the host to launch and immediately selects the conversation panel, so the click does not leave you on an empty page.
• Bilingual label / 中英双语 — the sidebar label follows the DSH UI language (网页版 / Web Chat).
• No dependencies / 零依赖 — nothing is imported from the DSH SDK; the host half spawns one PowerShell process.

Requirements / 运行要求

• Windows — the host half uses PowerShell and user32.dll window enumeration.
• Google Chrome — checked at %ProgramFiles%, %LOCALAPPDATA%, then chrome.exe on PATH. Without Chrome the URL is handed to the default browser instead (the focus step still works).

Install / 安装

From npm / 从 npm：

dsh plugin --profile web add dsh-open-deepseek-web

From GitHub / 从 GitHub：

dsh plugin --profile web add github:OWNER/dsh-open-deepseek-web

Restart DSH (or let the profile recompose), then reload the page. The whale button sits in the sidebar panel list, below the automation tasks.

重启 DSH 后刷新页面，侧边栏的上方面板列表中会多出一个鲸鱼按钮。

Usage / 使用

Click the whale button. The first click opens the window; later clicks focus it.

How it works / 实现

Half	File	What it does
Host	index.js	Registers POST /open-deepseek-web/launch on the host web server and runs a base64-encoded PowerShell snippet that focuses or launches the window.
Client	client.js	Registers the whale icon in the sidebar.panellist slot and a main panel whose mount requests the launch and switches back to the conversation.

The PowerShell snippet looks for a visible window whose title matches deepseek and does not match Harness — that second clause is there so the DSH window itself is never picked.

Known limitations / 已知限制

• Windows only. macOS and Linux hosts have no path through the host half.
• Title-based matching. A window is recognised by its title; rename the DeepSeek window's title (or run it in a language/frame that hides it) and the plugin opens a new window instead of focusing the old one.
• Any window titled with "deepseek" can match — another app with such a title may be focused first.
• No settings page. The Chrome path list and the title pattern are constants in index.js.
• The launch route carries no token. It starts a process and returns the action it took; it reads and writes no files. As with any host route, a same-origin page could call it.
