lonboard map to_streamlit

[jc9677]

Leafmap is fantastic and it's great to see support for lonboard already. I'm not sure how easy or difficult it would be to add a to_streamlit method for lonboard maps, but this would be useful for me!

lonboard has the to_html() method. It should be straightforward to add a to_streamlit() method, similar to the folium method. I will add that when I have time. Contributions are welcome.

It appears the HTML generated by lonboard has something special. It does not work with the streamlit html component. See #600. I don't have a solution yet.

[giswqs]

The same method works fine for folium maps.

@giswqs do you have an example of this? in my testing I'm just getting a literal data item back,

import streamlit as st
import leafmap.deckgl as lonboard
st.set_page_config(page_title="Lonboard Test")
m = lonboard.Map(center=[35, -100], zoom=3)
m.to_streamlit()

I have not used lonboard recently. The lonbard might have changed. Let me know look into it.

This seems a lonboard problem. The to_streamlit() method does not have any special.

    def to_streamlit(
        self,
        width: Optional[int] = None,
        height: Optional[int] = 600,
        scrolling: Optional[bool] = False,
        **kwargs,
    ):

        try:
            import streamlit.components.v1 as components

            return components.html(
                self.to_html(), width=width, height=height, scrolling=scrolling
            )

        except Exception as e:
            raise e
