Rebuilding After Code Changes

When you update code and want a new installer, rebuild the changed part then re-run

If it is still in development: npm run pack. If it already has a sharable .exe file: npm run dist:win.

What to rebuild

Delete the

What changed	Rebuild step	Development	Live
Frist step	release/win-unpacked folder	Delete the release folder
Frontend code	npm run build:frontend		npm run dist:win
Backend code	npm run build:backend		npm run dist:win
Python/AI service code	cd aiservice && python build.py		npm run dist:win
Electron code	npm run build:electron	npx electron-builder --dir	npm run dist:win

npm run dist:win already runs build:backend, build:frontend, and build:electron automatically — the only thing it doesn't do is python build.py (separate toolchain).

Day-to-day development

Nothing changes. You still use npm run dev, npm run desktop and/or .\release\win-unpacked\EPIC.exe as before — you only rebuild the installer when you want to share a new version.
