Comprehensive performance optimization guide for Angular 20+ applications with modern features like Signals, httpResource, signal inputs/outputs, @defer blocks, and native control flow syntax. Contains 35+ rules across 8 categories, prioritized by impact to guide automated refactoring and code generation.

Angular 21 development with signals, standalone components, reactive patterns, and strict TypeScript typing. \n \n Use standalone components with ChangeDetectionStrategy.OnPush , input() / output() functions, and computed() for derived state instead of decorators and ngClass / ngStyle \n Manage async data with resource() for signal-based fetching, handling loading/error states via hasValue() and status checks \n Build templates with native control flow ( @if , @for , @switch ), async pipes, and

NEVER trigger reflows/repaints in lifecycle hooks (ngOnInit, ngAfterViewInit).

Comprehensive guide to modern Angular state management patterns, from Signal-based local state to global stores and server state synchronization.

Custom directives for DOM manipulation, behavior extension, and component composition in Angular v20+. \n \n Attribute directives modify element appearance and behavior using the host property for event handling, class binding, and ARIA attributes; includes patterns for tooltips, highlights, buttons, click-outside detection, and keyboard shortcuts \n Structural directives handle portal rendering, lazy initialization, and template context injection for DOM manipulation beyond native @if , @for ,
