Shameless plug. I've choosen svelte for webextension that will be allow you to record, replay and modify requests on the fly. I've choosen Svelte, because 1. courisity and 2. it can compile to webcomponents and also reference webcomponents in normal svelte components. I discarded the webcompoments for everything idea, mostly because clunky passing and registering events with svelte (svelte issue). There few thing that needs to be polished, like typescript support and this events handling with webcomponents, but overall, very satisfied with svelte so far (as former React guy).
