Information

RxJS 8 is slowly taking shape. There's only an alpha version (8.0.0-alpha.12) available at the moment, but it look like v8 will be one of the biggest major releases in terms of breaking changes.

Here're some of them already available:

• https://github.com/ReactiveX/rxjs/blob/master/packages/rxjs/CHANGELOG.md#breaking-changes
• https://github.com/ReactiveX/rxjs/blob/master/packages/rxjs/CHANGELOG.md#breaking-changes-2

I think the lists can be reviewed and converted into tasks if issues are clear.

Here is just one example of breaking changes that affect NgRx:

• In https://github.com/ReactiveX/rxjs/pull/7202 RxJS team removed source field from Observable, so it's no longer a part of the API, while NgRx relies heavily on it: https://github.com/ngrx/platform/blob/71a9d7f2f4587ca975c5fd1087aab9b5db69c045/modules/store/src/store.ts#L33

Is it time to think about an adoption strategy?

Describe any alternatives/workarounds you're currently using

Ignoring RxJS v8 doesn't seem like an option.

Is there an open issue for RxJS 8 in the Angular repo? 👀 I couldn't find it.

I don't think they have it yet.
