Virtual DOM Functions

Right now, we have vdom.element() and vdom.text(). Currently they map directly off to Incremental DOM. However, we could create adaptors that could map to any backend. For example, we could serialise data to JSON that could be consumed by a web worker that returns diff / patch instructions for a different virtual DOM implementation.

In the same way we could keep support for Incremental DOM directly via a separate adaptor. This would allow us to create a server-renderer all without changing anything in our components' render() functions. Consumers could leverage whatever vDOM implementation they want via separate modules that they just plug in to their components, or we could just create base-classes / composable functions they call on their definitions to apply support for whatever the plugin is.

Our functions could also attain the same API as Hyperscript / React so it'd inherently be compatible with current JSX transpilers.

To render a component:

electron server.js --html "<x-app></x-app>" --scripts ./entry-point

Where --html is the HTML that you want to render and --scripts is the entry point that will be loaded prior to rendering the HTML. The entry point should contain all your component definitions that you need for the HTML to be rendered.
