Explain Components, Modules and Services in Angular

Question

Accepted Answer

Components, Modules, and Services are the three fundamental building blocks of Angular applications:

1. Components - Control a portion of the UI (view). They contain the template, styles, and behavior for a specific part of the screen.

2. Modules - Group related components, services, and other code together. Every Angular app has at least one module (AppModule).

3. Services - Contain business logic, data access, and reusable functionality that can be shared across multiple components.

Components handle the user interface, modules organize the application structure, and services manage data and business logic. This separation makes Angular applications modular, maintainable, and scalable.
