DoneJS is the combination of CanJS + Steal + DocumentJS + FuncUnit and some other glue projects. CanJS 2.3 - which adds support for server-side rendering - is due around the end of the month. There are alpha releases for DoneJS and beta for can-ssr

@matthewp I'm not clear on the question. In what circumstance would we care about a map inheriting? The event one might be an issue however.

Can anyone tell me what is the use of ' ! ' in defining the routes?

Chris Gomez

@akagomez

Where is it documented that you should use “!” to define routes?

avg6003

@avg6003

i am reading from here http://canjs.com/guides/Routing.html

It says to define a route I have to use '#!' in begining of the rout

what is the reason to use '!' ?

I tried without using !

its working but it automatically takes !

when i press back button then it first adds ! and then I press again the back button then it goes to previous route

Chris Gomez

@akagomez

Ah! I see. I can’t say. I’ve only worked with pushstate routing.

avg6003

@avg6003

do you know any source where I can find the reason?

Chris Gomez

@akagomez

Maybe in here? https://github.com/bitovi/canjs/blob/master/route/route.js

@akagomez a bit later than I wanted to, but here is that fix for the component's destroy method: bitovi/canjs#1886

@kiwi1342

for can.components sometimes is stated that we should use the 'scope' object

and other times 'viewModel'

viewModel is more explicit and understandable. Is it obsolete to use it?

Mohamed Cherif Bouchelaghem

@cherifGsoul

can.view.tag has not it's own scope!! is there way to make this happened without using component?

Guido Smeets

@gsmeets

@kiwi1342 scope will be deprecated in 3.0, use viewModel instead

kiwi1342

@kiwi1342

Wow. Good to know thx. One small suggestion: please work on canjs documentation. Canjs has great chances to compete with other more notorious frameworks such as backbone, knockout, react/flux. It has clear

It has clear advantages on performances and it's very easy to understand but it lacks in good tutorials.

@kiwi1342 I think Canjs is simple and easy to understand the trick is you have to see the whole application as composite from several components (Widgets) and glue those components with an application state (routing)

kiwi1342

@kiwi1342

One example is the place-my-order app which is not completed yet. In the component first page there are two videos which use the scope property. If obsolete they should be removed or filmed again with the new properties. I'm sorry if I sound too harsh but I really believe in canjs potential and have great expectations!

kiwi1342

@kiwi1342

@cherifGsoul you are absolutely right and that's what I was looking for for the past month. I've also asked for help on the JavaScriptmvc forum but no replies. https://forum.javascriptmvc.com/#Topic/32525000001855001

Mohamed Cherif Bouchelaghem

@cherifGsoul

@kiwi1342 did you see donejs?

kiwi1342

@kiwi1342

Yes. That's another thing that I find difficult to understand. First of all its in es6 and to be honest I'm not a big fan of that. And also for small projects I don't find necessary using steal for importing few js's

I remember reading this post posted by someone at bitovi. https://medium.com/@boopathi/it-s-the-future-7a4207e028c2

Mohamed Cherif Bouchelaghem

@cherifGsoul

Ok I understand, just FYI steal is not just a simple dependency management tool it can enhance the workflow

David Luecke

@daffl

I don't see a reason not to include a module loader into any project of any size. Just using npm install <package> and then using require('package') is so much less of a hassle than the mess with script tags.

Hi guys - I was wondering how to intercept all AJAX responses in CanJS. I want to intercept all responses and perform a certain action based on the status (i.e. 401 would redirect me to our login page, etc). Is that possible in Can? Thanks for the help!

Kevin Phillips

@phillipskevin

I’m not sure if there is a way to do this specifically in CanJS, but if you’re using can with jQuery you can use $.ajaxTransport() or one of the other low-level jQuery functions.

neelbhat88

@neelbhat88

@phillipskevin - Ah ok yeah that makes sense. I'll give that a try. Thanks a bunch!

can anyone explain How to animate mustache templates ? I am following the documentation from here https://github.com/canjs/can-animate/blob/master/doc/fade.md. But I cannot find the file can/view/animation.js in canjs downloads folder. So how can I load that file in application?

Kevin Phillips

@phillipskevin

@avg6003 can-animate is a plugin that you’ll have to install seperately.

Ilya Fadeev

@ilyavf

When I load can with npm it shows can.VERSION as "@EDGE" in browser console. Is this normal?

avg6003

@avg6003

@phillipskevin can you please give me a source from where I can download it? I could not find here: http://bitovi.bithub.com/canjs/plugin or http://canjs.com/download.html

@AntonProkofyev

Hi guys, looks like i found memory gap or probably i'm doing something wrong ). It happens when i'm trying to pass can.List into view and use {{each}} for this list. After i'm deleting the can.Control which contain the view i see the memory gap. it's not happens if i'm using can.Map instead. Is it known issue?

Kevin Phillips

@phillipskevin

@avg6003 you can get the source from github: https://github.com/canjs/can-animate/blob/master/src/lib/can-animate.js

Guido Smeets

@gsmeets

@AntonProkofyev which version are you using? 2.2.7 contains a bug that stops any control inside a component from destroying correctly. Use 2.2.6 until 2.2.8 is out

I'm talking about bitovi/canjs#1699

Mark Stahl

@mjstahl

Okay, so it is better to say something along the lines of:

~key is going to provide a compute, if the property is a value, it will convert it to a compute that will update the property on a change.

Justin Meyer

@justinbmeyer

which we are thinking of changing & to @ and * to ~

and we are dealing with new can.Map({ key: can.compute(1) })
