    @anthonyshort
    Yeah that’s the plan! We have a few ideas
    The key diffing could use some love, it’s probably one of the slower parts of the diffing

    it's a good plan. and I have a feeling it will work out. simpler systems have a great advantage over complicated ones. at least that's my opinion

    @anthonyshort sounds reasonable, so you use null to determine whether you are in the loading state, and set env data (app.set) + change state when your data are ready to be consumed?
    Anthony Short
    @anthonyshort
    Yep. So if say props.projects is null, it's loading. That way you don't need use component state (maybe)
    I think I want to try and setup a slack channel. Anyone know how to do it? Last time
    i checked it was a manual setup and you had to self host
    Anthony Short
    @anthonyshort
    Actually, super easy. dekujs.slack.com

    Let’s move the conversations over to Slack. If anyone wants an invite just send me an email at antshort@gmail.com. Not sure you can just let anyone join up.

    @anthonyshort that seems to be working... almost working.

    I am not using a router atm, but my goal is to have a card OR an answer
    so I thought I could set a generic prop called "data"
    right
    but at that point my app doesn't work, probably incorrect propType

    Are there any serverside rendering benchmarks for deku?
    Anthony Short
    @anthonyshort
    Not yet unfortunately. It wouldn't be too hard to create.

    just messin' around w/ loadtest

    the request handler is just executing this
    ``` 
    /** @jsx element */
import {element} from 'deku'
var xrange = require('xrange')

function renderNodes (number) {
  return xrange(number).map(function (i) {
    return (
      <div key={ i }>
        This is node { i }
      </div>
    )
  })
}

module.exports = (
  <div>
    { renderNodes(300) }
  </div>
)
    cool stuff :D
    react.renderToStaticMarkup is averge 10-20ms latency
    though i am not proficient w/ benchmarking tools so this may be off base
    Anthony Short
    @anthonyshort
    oh wow that’s awesome :)
    Would be good to get some perf tests into a repo somewhere
    Derek Reynolds
    @derekr
    yeah i'm about to push what i have now… it's pretty basic haha
    just wanted to do some quick comparisons
    Anthony Short
    @anthonyshort
    There’s this too: http://anthonyshort.me/dbmonster/
    There’s a React one around too, I think Deku is getting ~16 fps, React gets ~12 fps
    I mean, it’s not exactly realistic, but it’s kinda nice to get an idea for performance
    Derek Reynolds
    @derekr
    oh yeah that's rad
    i think that was used in a talk at react conf

    Deku doesn't have a router nor a built-in way to make async requests does it?
    Anthony Short
    @anthonyshort
    Depends what you're trying to do. Deku is really just there to render the vnodes. What problem are you having?
    bruce
    @sqram
    @anthonyshort No problems. I am going around looking at vdom libraries. I have used Mithril in the past, which comes with a builtin router and method for making async requests. So far, it's only one of the few I see that does it (riot.js and react being the others). Suppose I could include a small ajax library or make my own, but that's why i asked, to see if i have to :)
    bruce
    @sqram
    What exactly are 'propTypes' ? Cannot find that in the documentation anywhere.
    Kelly Miyashiro
    @kmiyashiro
    I believe those are to define the properties
    bruce
    @sqram
    Is there no doc to let us know what keys/values can go in there?
    Anthony Short
    @anthonyshort
    There's not much documentation on it because it was something we were trying out. It's going to get pulled out in the next version so it's not in core. Any validation library can do the same thing but better.
    bruce
    @sqram
    @anthonyshort understood. thanks.
    Anthony Short
    @anthonyshort
    @sqram related: dekujs/deku#176
    but yeah, the docs are kinda shitty in general at the moment
    bruce
    @sqram
    That's alright.
    I spent all of this past weekend trying all these vdom libraries popping out, decided to stick with deku for a personal project. Hope it sticks around
    Anthony Short
    @anthonyshort
    Yeah it definitely will, we’re using it for all of our app at Segment
