Angular

Angular is a comprehensive, TypeScript-based frontend framework developed and maintained by Google. Unlike library-focused alternatives, Angular provides a complete solution with built-in routing, forms, HTTP client, and testing utilities.

Key Features

• Full framework: Everything included out of the box
• TypeScript-first: Built with and for TypeScript
• Dependency injection: Powerful DI system for testability
• RxJS integration: Reactive programming with Observables
• CLI tooling: Generate components, services, modules
• Two-way data binding: Simplified form handling

Architecture Concepts

• Components: Building blocks with templates and logic
• Modules: Organise code into cohesive units
• Services: Shared logic and data access
• Directives: Extend HTML with custom behaviour
• Pipes: Transform displayed data

Example Component

@Component({
  selector: 'app-greeting',
  template: `<h1>Hello, {{ name }}!</h1>`
})
export class GreetingComponent {
  @Input() name: string = 'World';
}

Angular vs React vs Vue

Aspect	Angular	React	Vue
Type	Framework	Library	Framework
Language	TypeScript	JavaScript/TS	JavaScript/TS
Learning curve	Steep	Moderate	Gentle
Bundle size	Larger	Smaller	Smallest
Best for	Enterprise apps	Flexible projects	Rapid development

What We Like

• Consistency: Opinionated structure means consistent codebases
• Enterprise-ready: Built for large teams and complex applications
• Comprehensive: No need to evaluate and integrate many libraries
• Strong typing: TypeScript catches errors at compile time

What We Don't Like

• Complexity: Overwhelming for simple projects
• Bundle size: Larger than alternatives, though improving
• Learning curve: Many concepts to master
• Verbose: More boilerplate than React or Vue
• Breaking changes: Major versions have required significant migrations

When to Choose Angular

• Large enterprise applications
• Teams with Java/.NET backgrounds (familiar patterns)
• Projects requiring strong conventions
• Long-term projects with multiple developers

For smaller projects or more flexibility, consider React or Vue.
