Statebus Dev Diary Day #1

Hi bus drivers,

Thanks for the great framework! I've gotten it to work for my use case and just wanted to give you a shout out.

I'm writing values into statebus from a node client into a node server (running on localhost:80) and accessing
it from a webpage like this

<script type="statebus">
dom.BODY = ->
  DIV {},
    width: 100
    fetch('/abc').value
</script><script src="https://stateb.us/client6.js" server="http://localhost:80"></script>

I found that using absolute paths (leading slash) was necessary to persist values across refreshes from the web client,
but that from the server, the paths look relative, possibly b/c the "server scope" is considered a single thing,
but it's useful to consider every browser connection / refresh its own local scope.

If so, that's different than in the past when relative key paths used localStorage and persisted across browser refreshes.

I started up the server like so, and say messages showing a different client connecting with every refresh.
Cool!

Then I killed the server and restarted it:
