Description

Hello, First, thanks for providing this library! Here is what I do: I'm creating a file in the python code inside the web folder. This file is then used in the gui by a function of a JavaScript library. I just pass the path to the file to that function. My issue: This works all fine as long as I don't package the application with PyInstaller into one distributable binary (as you've kindly described in your readme). If I do that, then the frontend cant access the file. I guess the whole frontend runs in some kind of virtual environment with an own file system. The python code writes the file into the normal file system though. My question: Is there a way to access that virtual env from inside python? Or is there another way I should achieve this?

Contributor guide

Research direction
Investigate how PyInstaller handles file access when bundling Eel apps. The frontend runs from a temporary directory; use file or sys. MEIPASS to get the bundled resource path. Consider using the 'data' option in PyInstaller spec to include the file, or generate the file at runtime in a user writable location.
