Angular Standalone Components Best Practices Comprehensive guide for building modern Angular applications with standalone components, signals, and the latest Angular patterns. Modern Template Syntax Control Flow with @if, @for, @switch Use new control flow syntax instead of structural directives Implement proper track functions for @for loops Handle empty states and loading conditions Example control flow patterns: Reactive Forms with Signals Integrate reactive forms with signal-based state Implement form validation with signals Handle form submission and errors Example form integration: Routing and Navigation Functional Route Guards Use functional guards instead of class-based guards Implement route protection with signals Handle navigation state reactively Example functional guards: Lazy Loading with Standalone Components Implement route-level code splitting Load components and features on demand Optimize bundle size with lazy loading Example lazy loading setup: Summary Checklist [ ] Use standalone components to eliminate NgModule boilerplate [ ] Leverage inject() function for dependency injection [ ] Implement signals for reactive state management [ ] Use new control flow syntax (@if, @for, @switch) [ ] Create computed signals for derived state [ ] Implement functional route guards and resolvers [ ] Use lazy loading for optimal bundle size [ ] Write comprehensive tests for components and services [ ] Handle form state with reactive forms and signals [ ] Implement proper error handling and loading states [ ] Use signal inputs and function outputs for component communication [ ] Create reactive services with signal-based state Follow these patterns to build modern, performant Angular applications using standalone components and the latest Angular features.
