Just released wc-f7: https://github.com/blikblum/wc-f7
It allows to use web components like lit-element and skatejs in Framework7 as route components.
Can declare lifecycle hooks and page events directly in web component class and access specific properties like $app and $route
It’s smaller than Framework7 core because does not loads vdom, parser modules which are redundant for most web component developers
