In a static website, what happens to environment variables?

[gbrandt]

Question

My app uses environment variables to load a number of items, from database location to secrets. When I make a standalone app what happens to the env vars? Are they dropped, baked into the code sent to the browser?

Any insight would be helpful.

When the app is published as a standalone static website environment variables cannot be used anymore. You have to be especially careful with secrets as the entire app is delivered to a user's browser and run there.

As Flet app becomes a typical SPA I guess the regular approach would work there: doing all the secret work in backend API server with cookie- or JWT-based authentication. You can use fetch function in Pyodide to call an API: https://pyodide.org/en/stable/usage/api/python-api/http.html
