Angular 21+ Conventions

Modern Angular (version 21+) has evolved significantly from earlier versions. This skill provides decision trees and patterns for working with Angular 21+ codebases effectively.

Core Principles

Angular 21+ emphasizes:

• Standalone components as the default (no NgModules)
• Signals for reactive state management
• Functional APIs over class decorators where possible
• inject() function for dependency injection
• Zoneless change detection (optional but recommended)

Standalone Components

All components in Angular 21+ should be standalone by default.
