[valdenio]

I used ts-helpers and the error disappeared

[samuelpearce]

@valdenio I have ts-helpers installed but the error still appears. I do not have the line noEmitHelpers which other support answers suggest removing or setting to false. Did you have to make any other configuration to get it to work?

[valdenio]

I had set 'noEmitHelpers' to true and the error disappeared. But after that, i couldn't make the plugin work in ionic 2 virtual scroll. It just show transparent images with white borders ,then i changed my approach and used img instead of it (it wasn't a too large list)

I'm also getting this error with:

TypeScript: 2.0.9
Ionic Framework: 2.0.0-rc.4
Ionic Native: 2.2.11
Ionic App Scripts: 0.0.48
Angular Core: 2.2.1
Angular Compiler CLI: 2.2.1
Node: 6.9.1

Setting noEmitHelpers to false does not fix it for me.

Hey guys, I'm going to try and rebuild this plugin with some reorganization over the next 2 weeks and republish likely under new name ngx-image-lazy-load. The plan is to bring it fully up to speed with latest framework developments.

The Ionic virtual scroll issue is likely related to fact they are not tying into the window scroll event so an additionally setting would need to be provided here which could configure it for Ionic's virtual scroll.
