How do you structure Angular projects for scalability? ● Feature-based folder structure: Organize by features rather than by type. /src/app /products /components /services /models products.module.ts /orders /shared /core ● Core module: For singleton services used app-wide (e.g., authentication, logging). ● Shared module: For shared components, pipes, and directives reused across the
Answer: pp. Lazy load feature modules: Load modules on demand to improve startup time. Use state management (e.g., NgRx) when app state becomes complex. Adopt consistent routing with child routes.
What interviewers expect
- A clear definition tied to Angular in Angular projects
- Trade-offs (performance, maintainability, security, cost)
- When you would and would not use it in production
Real-world example
In a production Angular application, teams apply this when handling user-facing features or integration boundaries. For example, you might use it during a sprint where reliability and observability matter—logging metrics, validating edge cases, and documenting the decision in an ADR so future developers understand why the approach was chosen.
How to explain in the interview
- Define the concept in one or two sentences.
- Context — where it fits in Angular architecture.
- Example — a specific project, bug, or performance win.
- Trade-off — what you gain vs what you sacrifice.
Tip: Practice aloud on Toolliyo mock interview or the Interview Q&A section before your real interview.
