Streanlit custom components export

I have been creating custom components with react and fetching them from npm server as it has been described here Render a React component :: Streamlit Components Tutorial. Everything works great but my problem is that it adds a big amount of loading time to my app. I made sure that it wasn’t anything else stalling my app by first removing any components of my app and any data loading and noticing I still had the same loading time. Only after removing the imports from my_component folder my loading time dropped. So, is there a way to export them somehow and maybe not use an npm server or something?
