@fxck

lol

also the official heroexamplewhatever is using promises

Rob Wormald

@robwormald

that's a long story

Sekib Omazic

@SekibOmazic

Lesson learned: flatten your damn data structure.

Aleš

@fxck

https://github.com/gaearon/normalizr

Sekib Omazic

@SekibOmazic

@fxck Know that. Not using it (yet) ;-)

Aleš

@fxck

unless you have to work with some existing and unmodifiable apis, it'd be better to send the data already flat from the backend anyway..

Sekib Omazic

@SekibOmazic

Drawback of flatten backend - I need more backend calls. If I had Company->Departments -> Emplyees I'd need 3 API calls to build the tree

Rob Wormald

@robwormald

heh, i was just messing with a plunk dealing with this

not necessarily, if your backend is smart it can do sideloading

Aleš

@fxck

that's why I kind like what falcor is doing

Sekib Omazic

@SekibOmazic

@robwormald I'm all ears (eyes actually) Let me subscribe to your plunk ;-P

Aleš

@fxck

also redux + falcor seems to be(or will be.. should be.. whatever) working together

rackt/redux#560

Rob Wormald

@robwormald

i'd totally use normalizr but lodash deps ftl

Aleš

@fxck

yea

KenavR

@KenavR

Hi, when using inline (@component) styling is there a selector for the component? The tag name doesn't seem to work.

oh ok :host works

Rob Wormald

@fxck @SekibOmazic http://plnkr.co/edit/NWM1yJZbtoaShFMhsMCF?p=preview

Sekib Omazic

@SekibOmazic

@robwormald Great. Thanks a lot.

@Kylia669

No provider for IterableDiffers! (NgFor -> IterableDiffers)
hey getting this issue when trying to *ngFor="#item of items"
items - simple array of objects

what is wrong?

Rob Wormald

@robwormald

is it actually an array of objects?

Abhilash

@abhibly

Hie...I'm trying create auxiliary routes in deep linked routes...but im am not getting it...I tried according to this video https://www.youtube.com/watch?v=z1NB-HG0ZH4 and didnt succeed...I have created a plunker demo...how to rectify the mistake? http://plnkr.co/edit/MVWG76rh7PDvzc3oMYgB?p=preview

Aleš

@fxck

what's that @robwormald ?

http://plnkr.co/edit/NWM1yJZbtoaShFMhsMCF?p=preview

Sekib Omazic

@SekibOmazic

@fxck Answer to my questions (Observables, async pipe, template with async data,...) I'd say :-)

Aleš

@fxck

that object.assign syntax is hideous btw

Eric Martinez

@ericmartinezr

If I have a service which holds a http request to something, and I want to share its result across differents components without redoing the request, is ReplaySubject the best option? That's what I'm doing and it works perfectly, just want to be sure.

Sekib Omazic

@SekibOmazic

Well Immutable.jsisn't much prettier

@ericmartinezr I also use ReplaySubject(1) for that purpose

Eric Martinez

@ericmartinezr

Nice! I'm not the only crazy one! :P thx :D

Sekib Omazic

@SekibOmazic

You can try to decide upon http://www.introtorx.com/content/v1.0.10621.0/02_KeyTypes.html Couldn't see much difference to BehaviorSubject though

Eric Martinez

@ericmartinezr

Yup, probably BehaviorSubject would fit better since I'm passing one value, ReplaySubject can cache more than one. Thanks, I'll try that :+1:

Sekib Omazic

@SekibOmazic

There is also https://github.com/Reactive-Extensions/RxJS/blob/master/doc/api/core/operators/sharereplay.md

There are so many options

Abhilash

@abhibly

Is it possible to use aux routes in a router-outlet?

JavascriptMick

@JavascriptMick

just for the dummies, does the Tour of Heroes tutorial finish at toh4? I found a toh5 but there are lots of errors in the snippets

Aleš

@fxck

I'd stay away from the tour of heroes..

it's like "look, http returns an observable, so the best thing you can do, obviously, is to wrap that in a promise, and manually handle resolve and reject"... I think it confuses people and gives them all the wrong ideas

JavascriptMick

@JavascriptMick

yea, i took the data handing with a grain of salt

pantonis

@pantonis

Im a newbie in angular2

any tutorial on asp.net and angular2?

Aleš

@fxck

if you are a newbie, then learn angular2 basics first

say by watching this https://egghead.io/technologies/angular2

what backend you use after that is entirely up to you

Rob Wormald

@robwormald

@fxck ""look, http returns an observable, so the best thing you can do, obviously, is to wrap that in a promise, and manually handle resolve and reject"

where is that happening?

Aleš

@fxck

I'm probably exaggerating, but there is something similar happening, let me find it..
