@staltz
ok, what's the issue there?
Michal Vanko
@michalvankodev
runStreamAdapter.adapt is not a function
André Staltz
@staltz
hmm
Michal Vanko
@michalvankodev
yea I'm not using xstream run on the server side edit : yet!
Tylor Steinberger
@TylorS
Oh hey, I hadn't even thought about it, but @cycle/history should be automatically converted as well :+1:
Michal Vanko
@michalvankodev
Is @cycle/history adaptable?
Right now I have an issue with 
TypeError: sink$.subscribe is not a function
      at historyDriver (/home/mvanko/Projects/cycle-blog/node_modules/@cycle/history/lib/makeHistoryDriver.js:97:11)
      at Object.routerDriver [as router] (/home/mvanko/Projects/cycle-blog/node_modules/cyclic-router/lib/makeRouterDriver.js:32:20)
Tylor Steinberger
@TylorS
It returns just a single stream, so it should get converted automatically I think.
@staltz I can't remember now :( lol
cyclic-router isn't ready for conversion though :(
Let me open an issue for that

@TylorS

cyclic-router isn't ready for conversion though :(

NOooooooooooooooooo

Tylor Steinberger
@TylorS
I want to rewrite it in TS and XStream
Definitely high on my todo list
Michal Vanko
@michalvankodev
Thank you.. My todays journey is therefore in the end.. If there is any way to help you I'd like to :)
Tylor Steinberger
@TylorS
If you'd like to submit a patch for simple conversion before it gets rewritten that'd be very welcomed, but I don't expect it from anyone. Not many people are familiar with how to do the conversions inside of drivers just yet
Michal Vanko
@michalvankodev
What is your estimate for a rewrite?
I can perhaps help you with that
Tylor Steinberger
@TylorS
I'm trying to get a tangible POC of a library I'm writing right now (probably by the weekend), then my priorities are most-run and most-adapter (mostly done), and then converting all of my existing libraries.
André Staltz
@staltz
It's rather easy to make a driver ready for Cycle Diversity
Really, it's
function makeMyDriver(lol) {
  function myDriver(sink) {
    // ...
    return source;
  }
  myDriver.streamAdapter = RxAdapter; // <=== this
  return myDriver;
}
Michal Vanko
@michalvankodev
nice going to try it out :)
André Staltz
@staltz
So try that out and make a PR to cycle/history if that's the case
Michal Vanko
@michalvankodev
of course :) going to relax a bit
and then i will take a look at it.. looks really simple
Laszlo Korte
@laszlokorte
@staltz doesn't sink need to be converted by the driver as well?
Oh, never mind, cycle does that automatically, right? but nested streams need to be converted manually?

hello, guys! i'm just start to play with cyclejs, and when i try to run simple examples, like checkbox, i'm always get error like:

this.runStreamAdapter.adapt is not a function

core v6.0.3
do i need to create issue? i have standart webpack app with babel, rx and cycle-dom ;d

@staltz
@laszlokorte yes laszlo, Cycle run converts sinks to the driver's stream lib, but I think sinks are always first-order, so no need for flattening :smile:
Laszlo Korte
@laszlokorte
Sorry, I meant nested sources, like the ones in the http driver
Steve Lee
@SteveALee
those xstream performance results are very interesting - well at least to me :) SO yes xstream in same ballpark as RxJS 5 - sometimes faster, sometimes slower. Most is impressive. Note sure about Array though.
Adam Wendell
@AdamWendell
@frontendthug With "@cycle/core": "^6.0.3" you don't need a adapter
André Staltz
@staltz
Yeah, the driver receives from run the stream lib used by the application, so the driver needs to adapt the stream before giving it as sources @laszlokorte
Adam Wendell
@AdamWendell
So you might need to use a older version of the @cycle/dom. But I'm not sure. Haven't played around enough with the latest to be sure.

Hey guys, I guess my question is going to be dead simple for you, but I don't understand why the proxy$ stream doesn't produce any value here :
javascript 
function log(from) {
  return function () {
    console.log(from, arguments);
  };
}

const proxy$ = new Rx.Subject();
const value$ = Rx.Observable.just("test");

value$.subscribe(proxy$);
value$.subscribe(log("original"));
proxy$.subscribe(log("proxy"));
here is the corresponding jsbin : https://jsbin.com/vihuga/edit?html,js,console
And this is where I got the idea of the proxy (the todo example app) : https://github.com/cyclejs/todomvc-cycle/blob/df4486354529d0db23659159d079884f60b62f48/src/components/Todos/index.js#L80
is this a problem of hot/cold or completed stream?
Laszlo Korte
@laszlokorte
@atomrc yes, The proxy receives the "test" value before itself has any subscribers
You could either use a ReplaySubject or put the value$.subscribe(proxy$); call in the end
Thomas Belin
@atomrc
oh indeed putting it at the end is working, thk @laszlokorte
I find this pretty hard to understand at the beginning
Laszlo Korte
@laszlokorte
but is it clear now? Or should I elaborate?
Thomas Belin
@atomrc
No it's ok I got it thk :) The thing is I though this was my problem for the unit test I am writing but it not the same problem is seems :(
so I guess I'll have to dig a little deeper to find the source of my problem

@staltz perfect timing with xstream - was literally just trying to convince my team to start incorporating FRP into our project, but they were looking for something lightweight to prove the concept
