What this skill does
Angular Best Practices Comprehensive performance optimization guide for Angular applications. Contains prioritized rules for eliminating performance bottlenecks, optimizing bundles, and improving rendering. When to Use Reference these guidelines when: Writing new Angular components or pages Implementing data fetching patterns Reviewing code for performance issues Refactoring existing Angular code Optimizing bundle size or load times Configuring SSR/hydration --- Rule Categories by Priority Priority Category Impact Focus -------- --------------------- ---------- ------------------------------- 1 Change Detection CRITICAL Signals, OnPush, Zoneless 2 Async Waterfalls CRITICAL RxJS patterns, SSR preloading 3 Bundle Optimization CRITICAL Lazy loading, tree shaking 4 Rendering Performance HIGH @defer, trackBy, virtualization 5 Server-Side Rendering HIGH Hydration, prerendering 6 Template Optimization MEDIUM Control flow, pipes 7 State Management MEDIUM Signal patterns, selectors 8 Memory Management LOW-MEDIUM Cleanup, subscriptions --- 1. Change Detection (CRITICAL) Use OnPush Change Detection Prefer Signals Over Mutable Properties Enable Zoneless for New Projects Benefits: No zone.js patches on async APIs Smaller bundle (~15KB savings) Clean stack traces for debugging Better micro-frontend compatibility --- 2. Async Operations & Waterfalls (CRITICAL) Eliminate Sequential Data Fetching Avoid Client-Side Waterfalls in SSR --- 3. Bundle Optimization (CRITICAL) Lazy Load Routes Use @defer for Heavy Components Avoid Barrel File Re-exports Dynamic Import Third-Party Libraries --- 4. Rendering Performance (HIGH) Always Use trackBy with @for Use Virtual Scrolling for Large Lists Prefer Pure Pipes Over Methods Use computed() for Derived Data --- 5. Server-Side Rendering (HIGH) Configure Incremental Hydration Defer Non-Critical Content Use TransferState for SSR Data --- 6. Template Optimization (MEDIUM) Use New Control Flow Syntax Avoid Complex Template Expressions --- 7. …
