Besides dop, DerbyJS/Racer seems to be dead, Apollo might be a solution but seems to require some setup, Meteor is too heavy, and Feathers with RxJS seems like a possibility. I'd be interested in any tools for getting easy client-server sync or reactivity.
Statebus can easily synchronize N clients to N servers, and has a very nice wrapper on top for reactive UI widgets to respond to changes in state. Here's a hello world example:
dom.BODY = -> # Let's define the body tag as a function
DIV
backgroundColor: '#eef'
'The time is '
fetch('state://server.com/time').now
' and the weather is '
fetch('state://another.org/weather/oakland,ca').brief
If it can be used seamlessly with Vue/React (as mentioned in older discussions) such that changes are propagated into them, I'd be interested to try it. (Those libraries are in heavy use already so your solution would have to work with them for a decent chance at traction, I think.)
(1) It does work with React natively, and in fact the example I gave above uses React under the hood. Here's how to do the same thing with raw react:
<script src="https://stateb.us/client6.js"></script>
<script>
var body = statebus.create_react_class({
render: () => { // This function will re-run whenever
return React.DOM.div( // any state fetched below changes
{style: {backgroundColor: '#eef'}},
'The time is ',
fetch('state://server.com/time').now,
' and the weather is ',
fetch('state://another.org/weather/oakland,ca').brief
)
},
displayName: 'body'
})
setTimeout(_=> React.render(body(), document.body))
</script>
I would love to help you give it a try and see what you think! Please send me an email or text (toomim@gmail.com or 510-282-4312) for feedback and assistance.
2) We are currently OT/CRDT/Version Control into it. We've come up with a new approach here, which I'm very excited about. I'm also looking for folks to beta-test or give early feedback on our approach as we polish it up.
I'm also interested in adding Vue support. If you'd like it, I'll add it.
