Integration with streamlit

[sandipde]

Hi Guillaume, I am trying to integrate parts of chemiscope especially the molecule viewer with all the frame,and options into streamlit apps. A native 3dmol visualization which chemiscope is also based on can be easily integrated via exporting HTML components as done in here --> https://github.com/napoles-uach/stmol/blob/9fced0e5b86ddda3592eb343016487df0238253b/stmol/init.py#L24

Do you have something equivalent already? I believe you are doing something similar when making the jupyter widget but could not find something suitable that can be embedded as HTML component in streamlit.

So the HTML part is fine, you just need to create a couple of div each with an id. Then to render a chemiscope widget in there, you'll need to run some JS code to create the widget. For a molecule viewer, something like this:

<!-- HTML -->
<div>
  <div id="meta-id"></div>
  <div id="structure-id"></div>
  <div id="info-id"></div>
</div>

// JS
const config = {
    meta="meta-id",
    structure="structure-id",
    info="info-id",
};

const data = JSON.parse("the data you want to visualize");

chemiscope.StructureVisualizer.load(config, data);

The corresponding API documentation is here: https://chemiscope.org/docs/api/classes/StructureVisualizer.html

Here is the corresponding code in the jupyter extension: https://github.com/lab-cosmo/chemiscope/blob/634136b3d09cc32c9b951d1eb76293b2a872ec9a/python/jupyter/src/widget.ts#L194-L228
