download_file, new_folder upload_file options not working

[nheine]

How can I get these options: download_file, new_folder upload_file to work? I set the to true while in static_file_server mode. I don't have a static file server path, do I need that?

Hi, the upload_file and new_folder function are out of scope if you don't use use_static_file_server mode. But if you want, maybe you can develop those feature then you can commit pr or not. For example:
StFileBrowser.tsx

newFolderHandler = (key: string) => {
    key && noticeStreamlit({ type: StreamlitEventType.CREATE_FOLDER, target: { path: key } })
  }

<div>
        <FileBrowser
          // ...other code
          onCreateFolder={this.newFolderHandler}
          actionRenderer={(...args: any) => {
            return Actions({
              ...args[0],
              ...{
                // other code
                canCreateFolder: that.args.show_new_folder,
              },
            })
          }}
        />
      </div>

As for the download_file, you have to pass the params artifacts_site and artifacts_download_site. artifacts_site to be used when preview some files and artifacts_download_site to be used to download file. You can create a file server proxy using nginx or caddy, for caddy example:

http://localhost:1024 {
    log {
        output stdout
        level DEBUG
    }
    header /download/artifacts/* {
        +Content-Disposition "attachment"
    }
    route /download/artifacts/* {
        uri strip_prefix /download/artifacts
        file_server {
            root ./example_artifacts/
            disable_canonical_uris
        }
    }  
    route /artifacts/* {
        uri strip_prefix /artifacts
        file_server {
            root ./example_artifacts/
            disable_canonical_uris
        }
    }
    reverse_proxy /* 0.0.0.0:8501
}

Then you need to add artifacts_site and artifacts_download_site:

    st.header("With Artifacts Server, Allow choose & download")
    event = st_file_browser(
        os.path.join(current_path, "..", "example_artifacts"),
        artifacts_site="http://localhost:1024/artifacts/",
        artifacts_download_site="http://localhost:1024/download/artifacts/",
        show_choose_file=True,
        show_download_file=True,
        key="B",
    )
