NGX Compatibility: TypeError: Cannot read property 'kind' of undefined

[jamesthurley]

Hi, great library. I've tried the following steps on Angular CLI 1.5.2 and 1.5.5:

ng new scrollimate-test
cd scrollimate-test
npm install ng2-scrollimate --save
ng build --prod

The above succeeds, however if I add import {Ng2ScrollimateModule} from 'ng2-scrollimate'; to the top of app.module.ts and add Ng2ScrollimateModule to the module imports list, and then run ng build --prod again, I get the following error:

ERROR in ./node_modules/ng2-scrollimate/dist/src/ng2-scrollimate.directive.js
Module build failed: TypeError: Cannot read property 'kind' of undefined

It works fine without --prod and works fine running under ng serve. Removing Ng2ScrollimateModule also makes it work again.

Interestingly if I bring the four typescript files from your src directory into my project as a local module it also works fine.

Hey @jamesthurley, unfortunately this module only supports Angular 2.x. The Angular CLI versions you are using create Angular 5.x apps...

Hi @bergben, thanks for the quick reply! Interesting, I saw that in your readme but hoped it really just meant "not Angular 1.x" ;)

It's actually working well for me in 5.x for my limited use case. Is there something specific you know of which doesn't work which I should avoid? (other than the above issue, which I've worked around for the moment!)

Out of interest, how come you stopped developing it? Is there another library you'd recommend instead?

Mostly I just lack time for further development for the module. I think I know what breaks it for Angular 5, as for some of my other libraries it is probably the build optimizer: https://github.com/bergben/ng2-img-max/issues/17 So to be compatible it wouldn't even take that much but IDK if by now certain things could be done in a better way, I'd have to go over the code...
