/**
|
|
* free-ports — kill whatever process is LISTENING on the given TCP port(s).
|
|
*
|
|
* Used as a preflight for the dev commands (`dev`, `dev:web`, `serve:web`).
|
|
* On Windows especially, Ctrl-C'ing `tauri dev` / `concurrently` often leaves the
|
|
* spawned Vite (`node vite.js`) or backend child orphaned, still holding 5173 /
|
|
* 8787. Because Vite is pinned with `strictPort: true` (it MUST match Tauri's
|
|
* fixed `devUrl` :5173) and `dev:web` binds both processes with `concurrently -k`,
|
|
* a single stale listener makes the whole command fail with "Port already in use".
|
|
* Clearing the port first makes the next start self-healing.
|
|
*
|
|
* Cross-platform: Windows (netstat + taskkill), macOS/Linux (lsof + kill).
|
|
* Usage: bun scripts/free-ports.mjs 5173 8787
