Only allow Voila app to access a specific directory

[giswqs]

When deploying a geemap web app using Voila, the open file dialogue allows access to the entire system directory, which is a security risk. ipyfilechoose v0.6.0 now allows restricting access to a specific directory by setting the sandbox_path property.

fc3 = FileChooser('/content/sample_data')
fc3.sandbox_path = '/content'

This feature has been implemented. One can now specify a sandbox_path. When the app is deployed using Voila, open-file dialogue can only access files within the sandbox_path, avoiding unauthorized access to system directories.

m = leafmap.Map(sandbox_path='/path/to/folder')
