ie11 crash in angular application with message of memory issue

[David Michael Gang]

Hi all,

I have an angular application (with  ng-forward) with a search box and search results. On all browsers except ie11 everything works fine.  If i make a couple of searches, in ie11 the pplication crashes with a lot of error messages

The first message is 

Error: Out of memory <button class="section-title md-button" aria-label="{{::('facets.facet.facet_'+ ctrl.facetGroup.name | translate)}}" type="button" ng-class="{'collapsed': ctrl.facetGroup.facetGroupCollapsed}" layout-fill="" (click)="ctrl.facetGroup.facetGroupCollapsed = !ctrl.facetGroup.facetGroupCollapsed" ng-transclude="" translate-attr-title="{{ctrl.facetGroup.facetGroupCollapsed ? 'nui.facets.expand.tooltip' :'nui.facets.collapse.tooltip'}}">

Afterwards i have lots of unknown provider errors.

As I attached in the screenshot, the memory usage is not high at all.

Does anyone have a clue why this happens?

Did anyone experience such an error with an ie11 app?

Thanks,

David

Hi David,

Can you make a sample that reproduces this scenario? Preferably one that can run on its own, without any dependencies.

Hi,

It looks like the problem is in the ng-forward part of the program.

The problem is that it is not maintained anymore.

Thanks,

David

Hi David,

Perhaps you can switch to ngMetadata. For myself, I have no real experience with either of those. If you have used one of them to its full extent, perhaps you can even port the application to 2 easily? (that is the idea of both projects, right ;) )

Hi Elias,

You are right

I would like to switch to angular 2 but cannot because the program is written with angular material . Am2 is far from being production ready.

I will try to fix somehow the problem .

If this does not work I will switch either to ngmetadata or plain angular components 

Thanks

David

Hi all,

I pinpoined the problem.

It is connected to the core-js polyfill of Symbols. 

https://github.com/zloirock/core-js/issues/260

This defect is unfortunately unfixable.

I wonder if angular2 could also suffer from this defect.

Thanks,

David

Hi David,

Good catch! I'm not entirely sure Angular 2 does not use symbols, but I think they are rare at least. So it should be a less pertinent problem.

Also, do you really need IE11? Did you measure what part of your audience is using it? You might be surprised ;) For my own projects I was able to ditch IE long ago, but I know that's not possible for all developers.
