bun run dev   # runs `nx serve app` (Angular dev server, HMR) + `electrobun dev` together

The desktop shell (Bun main process, window/menu/tray code) lives in apps/desktop/src, separate from the Angular UI in apps/app — they're different runtimes with different tsconfigs. Edit apps/desktop/src/index.ts and restart electrobun dev manually to see changes — do not use electrobun dev --watch on Windows, see below.

Known issues

• Killing electrobun dev leaves orphaned processes on Windows (electrobun#168): killing the app only kills the top-level launcher.exe; the actual bun.exe process and its WebView2 tree survive. Two symptoms:
  • With --watch, the next rebuild fails with EACCES: permission denied, rm build\dev-win-x64 (the orphaned process still has those files open). Workaround: fully close the app window before the next edit, or just skip --watch and restart electrobun dev manually — UI iteration already gets HMR from the Angular dev server above, so --watch is rarely needed.
  • Without --watch, if a session gets killed from the terminal (not the window's close button), the orphaned bun.exe/WebView2 tree keeps holding the WebView2 user-data folder. The next electrobun dev then fails immediately with ERROR: Failed to create WebView2 controller, HRESULT: 0x800700AA (ERROR_BUSY). Fix: find and kill the leftover bun.exe/launcher.exe/msedgewebview2.exe processes under build\dev-win-x64, then retry.
