Run example

1. Download the repo & enter the repo

git clone git@github.com:pragmatic-streamlit/streamlit-file-browser.git
cd streamlit-file-browser

2. Install frontend package

cd streamlit_file_browser/frontend/
npm install

3. Set develop env

export FILE_BROWSER_DEVELOP_MODE=True

4. Start frontend and python server

cd streamlit_file_browser/frontend/ && npm run start

Static File Server Mode

Streamlit file browser support custom file server. You can provide a file server path.

For example

event = st_file_browser(os.path.join(current_path, "..", "example_artifacts/static_file_server/root"),
    key="deep",
    use_static_file_server=True,
    show_choose_file=True,
    show_delete_file=True,
    show_download_file=False,
    show_new_folder=True,
    show_upload_file=False,
    static_file_server_path="http://localhost:9999/?choose=true",
)

There is a demo in this repo, you can enter the example_artifacts/static_file_server path and run sh test.sh to start the custom file sesrver.

The custom static file server use this repo: https://github.com/y805939188/gohttpserver

It has better performance in terms of function and performance, and you can also directly use this repo as a static file service.
