Proper package for Angular

[mhartington]

Describe the Bug
Right now the ionic/angular is not shipping using the Angular package format. This is creating issues where webpack will pull in ES6 code, when the expected result is to use ES5. Specific example, building out the server side portion of an app with Angular universal will lead to build failures due to ES6 import statements.

Additional Context
We should investigate using ng-packagr to properly bundle the angular portion of the library to create the correct format entries.

I think it is really important issue. I'm using async, await and it causing my app white screen.

@hiepxanh as mentioned in this ticket #15038 at the moment Android 7.1.1 (patch levels are important!) and the related SDK API version is the minimum required Android version for Ionic 4 to work on Android. The mentioned tickets also suggests a workaround for older versions of Android using the Android System Web View system extension on these devices.

but the work around using webpack method not working with me, it broking my app

[mhartington]

I think this can be closed for now. @ionic/angular is shipping the correct code needed for Angular's tools to work and for webpack to properly import things.

As it stands the core ionic components get both an ESM build and a ES5 build if the browser supports certain features. As far as using features like async/await, the project build tools will transpile this down to ES5 for browser that don't support it natively.
