Framework
Angular
A batteries-included TypeScript framework: DI, router, forms — closer to Symfony than to a UI library.
Angular’s particularity is that it is a platform: modules (or standalone), dependency injection, RxJS, a compiler. PHP seniors recognise the shape — it feels like a framework, not a render function.
Strength: large teams, opinionated structure, enterprise tooling. Limit: ceremony. A small Ibexa front does not need it. Signals (recent Angular) shrink the RxJS tax for local state.
Pick it when the front is a long-lived product with many developers. Not when you need a widget on a Twig page.
