Component-Based Architecture structures the UI as a tree of reusable, self-contained components that encapsulate their own template, logic, and styles, promoting reusability and maintainability [citation:5].
Component-Based Architecture is the foundation of modern frontend frameworks like React, Angular, and Vue. It encourages breaking the user interface into small, reusable, and self-contained pieces called components. Each component encapsulates its own template (HTML), logic (JavaScript/TypeScript), and styles (CSS), making it easier to develop, test, and maintain large applications. This pattern naturally promotes a component tree structure where data flows from parent to child via props, and events bubble up from child to parent [citation:5].
