I have tried building app back-end with Nuitka and managed to make it work with like so:
nuitka3 --standalone --include-module=app.middleware --include-package=pgmanage --include-package=django --output-dir=dist ./pgmanage-server.py
The some data files should be added to the project dist directory in order to make it work.
The app starts up significantly faster but my main concern is the size of the build, which is almost 200% of what we get with pyinstaller. Perhaps the size could be optimized by selectively including only necessary python modules instead of using whole packages.
