DSH-Launcher

Launching the dsh Web UI on Windows used to mean opening a terminal, running a command, babysitting a console window, and manually killing leftover node processes to free the port after closing the browser. DSH-Launcher collapses all of that into a single ~360 KB executable: double-click to start, the browser opens automatically; close the browser and the entire process tree is torn down via a JobObject in one shot—zero residue, zero flicker, zero terminal.

It has no WebView2 dependency, no bundled runtime, and no requirement for a global dsh install. At startup it resolves the dsh binary through a discovery chain (config path, offline vendor directory, PATH, then npx), and confirms genuine readiness with a TCP connect plus an HTTP response check rather than merely testing whether the port is open. If the browser is a shared instance, the launcher degrades to a resident tray mode so it never kills windows you are actively using. Air-gapped and intranet environments are supported as well—drop the dsh package into the vendor directory and the whole flow works offline.

Ideal for Windows developers who invoke the dsh Web UI frequently: double-click to go, close the browser to stop, no extra components to install, no lingering background processes, and stable launches in both online and fully offline settings.
