RxJS + Angular: Version Matrix

RxJS is a core Angular dependency. Using the wrong version causes compilation errors or runtime issues. Here's the definitive compatibility guide.

Quick Reference

• Angular 20: RxJS 7.4+ (RxJS 6 not supported)

Migrating from RxJS 6 to 7

If you're on Angular 13+ with RxJS 6, you should upgrade:

1. Install: npm install rxjs@7
2. Remove compat layer: npm uninstall rxjs-compat
3. Update imports — RxJS 7 removed some deep import paths
4. Check for breaking changes in operators you use
