Angular vs React

Angular and React represent two philosophies of frontend development. Angular is a full platform that prescribes how you build, test, and structure applications. React is a composable library that lets you choose your own routing, state management, and tooling.

Platform vs Library

Angular provides dependency injection, a powerful forms module, an HTTP client, routing, animations, and testing utilities — all maintained by the Angular team. This consistency is valuable for large organizations with multiple teams working on the same application.

React provides a component model and rendering engine. Everything else — routing (React Router), state management (Zustand, Redux), data fetching (React Query, SWR) — comes from the ecosystem. This gives maximum flexibility but requires more architectural decisions.

The Enterprise Question

Angular's strict conventions make it predictable. A new developer joining an Angular project knows where files go, how services are injected, and how routing works. This consistency is why enterprise organizations (banks, government, healthcare) often choose Angular.

React's flexibility makes it adaptable. Every React project can look different, which is both a strength (teams can optimize for their needs) and a weakness (inconsistency across an organization).

System Design Implications

For system design interviews, the frontend framework rarely changes the system architecture. Both Angular and React support SSR, code splitting, lazy loading, and CDN deployment. Focus on the backend architecture and data flow.
