Ionic-framework: feat: Angular 9 Support

[godenji]

Feature Request

Ionic version:
[x] 4.x

Describe the Feature Request
Angular 9 will be released in the next month or so; Ionic/Angular should extend support beyond current 7.x/8.x range.

Additional Context
Angular 9 will bring by-default Ivy based builds, latest TypeScript, and (finally) fast incremental compilation to Ionic/Angular projects. Let's stay ahead of the curve and not wait too long to support the latest & greatest from Angular + TypeScript.

I have to agree, Angular 9 support as soon as possible would be awesome :)

First Angular 9 RC is now available.

Upgrade guide is here:

Angular 9 GA scheduled for end of November.

now ionic cannot work well with threejs r0.109?

Angular 9 RC5 released a few days ago.

What's the ETA on Ionic + Angular 9 when the GA lands? Ideally Ionic users won't have to wait months for the latest and greatest from Angular.

Ideally Ionic itself will have full support for Angular 9 so all the benefits of Bazel + Ivy are realized both within Ionic and client apps (DCE/tree shaking are vastly improved, would be fantastic to reduce core bundle size, not to mention have much faster builds).

I just provided a PR for basic Angular 9 support. The library isn't compiled with Ivy yet in the commit, but it should allow you to upgrade your application to Angular 9 until actual Ivy support is introduced (currently being worked on in branch https://github.com/ionic-team/ionic/tree/angular-ivy). Existing Ionic applications (e.g. Angular 8) should continue to work with this commit.

PR has been closed by Ionic team, see https://github.com/ionic-team/ionic/pull/19515 for Ivy support
