You could use a framework like lit-element, or StencilJS which uses JSX. And if you want to get the full React experience you can use Preact library which has full support for Web Components.

If React focused on becoming closer to the DOM like Preact (no more synthetic events and support for custom events and web component properties as props) instead of the (over-engineered?) Concurrent mode the world would be a better, more unified place imo.
