easy, using vanilla.js ! you attach event-handlers to each virtual-dom the same way you would do with a normal-dom. and those event-handlers can react to change the way you want. If you mean how to do auto-data binding oldDom = patch (document.body,newDom) newDom = h ('div','hello world') patch (oldDom,newDom) patch is the function that does the dom diffing. The amazing thing is most web components do not need auto-diffing. Sometimes you want fine grained control where you write your own update functions - making imperative changes to the dom based on your needs. And for other web components where you want more auto-updates you can patch accordingly. The thing that is amazing is that you can dial it up and down based on your individual needs. A good example is table components with a lot of data. You really do not want to incrementally update the table. So for the divs with the data you patch but other components that have a lot of interactivity you can simply not patch and do updates by hand.
