access local folders/files when marimo app is served using WebAssembly

[jacowp357]

How can local files be accessed (from the web browser) for read+write when I serve a marimo app?

Example: I want to access a image from my local drive and change it and save it on my local via my Marimo app running with WebAssembly.

@jacowp357 you could use mo.ui.file() to show a file button to upload a file that can be accessed with .value. https://docs.marimo.io/api/inputs/file/
