To build Angular v20 components using signals, use standalone-first architecture with input(), output(), and computed() patterns for derived state, ensuring OnPush change detection and strict template control flow.

The best way to structure reactive Angular component inputs and outputs is using the signals-driven input() and output() APIs alongside computed() for derived state, replacing outdated property decorators and binding styles.

To migrate Angular templates to the new control flow syntax, replace structural directives like *ngIf and *ngFor with strict template control flow rules, and remove ngClass or ngStyle to avoid readability and performance pitfalls.

Yes, this Angular component architecture requires standalone-first components without NgModules. It enforces modern component structure suited for Angular v20+, including OnPush change detection and explicit template guidance.

You should use computed() instead of methods for derived Angular signal state because it standardizes reactive state management, ensuring components remain predictable and maintainable without outdated binding styles.

When refactoring component TypeScript files, avoid outdated Angular APIs including NgModules, property decorators for inputs and outputs, structural directives like *ngIf, and ngClass or ngStyle bindings.
