@ionic/angular combines the core Ionic experience with the tooling and APIs that are tailored to Angular Developers.

Ionic supports Angular 6.0.0 and up. As part of their upgrade strategy, Angular has built-in tooling to help automate upgrades and provide feedback to developers whenever changes to an API occurred. This reduces update friction and keeps the ecosystem in a evergreen state.

With Ionic 4+, the official Angular stack for building an app and routing are used, so your app can fall in-line with the rest of the great Angular ecosystem. In cases where more opinionated features are needed, Ionic provides @ionic/angular-toolkit, which builds and integrates with the official Angular CLI and provides features that are specific to @ionic/angular apps.
