A command line tool to provide advanced features (CDN, etc) for streamlit by apply patch to the installed packages.
pip install streamlit-hotfix
st-hotfix --helpFor developer,
cd streamlit-hotfix
poetry install
python -m st_hotfix --help
Note that you have to install this tool in the same environment as streamlit and streamlit components you want to patch. Otherwise, the patch may not work as expected.
# dump assets to a folder
st-hotfix cdn dump streamit ./path/to/streamlit-assets
# now you can distribut streamlit-assets with CDN, for example jsDelivr
# e.g: https://cdn.jsdelivr.net/gh/link89/assets@0.1.0/cdn/streamlit/
# then you can patch streamlit to load assets from CDN
st-hotfix cdn patch streamlit --cdn_url https://cdn.jsdelivr.net/gh/link89/assets@0.1.0/cdn/streamlit/Now when you run your streamlit app, it will load assets from the CDN.
Note that the CDN tool makes use of the on-the-fly mode of webpack publicPath.
Since streamlit 1.36.0, the publicPath of streamlit frontend can be override in runtime by setting window.____WEBPACK_PUBLIC_PATH_OVERRIDE.
If the components are not allow to change the publicPath on-the-fly, you have to patch them first by yourself before using this tool to patch it with CDN URL. For example: https://github.com/mik-laj/streamlit-ketcher/pull/120/files
You can always revert the patch by running
st-hotfix cdn restore streamlit
