Additional Concepts

This chapter provides a quick start guide, curated learning resources, study plans, interview preparation tips, and a glossary to help you continue your Angular journey.

Quick Start Guide

Get started with Angular in five steps:

# 1. Install Angular CLI
npm install -g @angular/cli

# 2. Create a new project
ng new my-first-app --routing --style=scss

# 3. Navigate to the project
cd my-first-app

# 4. Start the development server
ng serve --open

# 5. Generate your first component
ng generate component hello-world

Your application is now running at http://localhost:4200. Edit src/app/hello-world/hello-world.component.ts to customize it.

8-Week Study Plan

Follow this plan to go from beginner to productive Angular developer:

• Week 1-2: TypeScript, components, templates, data binding
• Directives, pipes, services, dependency injection
• Routing, forms (template-driven & reactive)
• RxJS, HTTP client, error handling
• State management (Signals, NgRx), guards
• Testing (Jasmine/Karma), Angular Material
• PWAs, SSR, production build & deployment

Interview Prep Questions

Common Angular interview questions:

1. What is the difference between *ngIf and [hidden]?
2. How does Angular's change detection work?
3. Explain the difference between template-driven and reactive forms.
4. What is a Subject and how does it differ from a BehaviorSubject?
5. What are Angular lifecycle hooks? List them in order.
6. How do you implement lazy loading?
7. What is the Ivy compiler and what benefits does it bring?
8. How does dependency injection work in Angular?
9. What are standalone components and when should you use them?
10. How do you optimize an Angular application for production?

Resume Builder Tips

When listing Angular on your resume, highlight specific achievements:

• Mention the version(s) of Angular you have used
• Describe the architecture (standalone vs module-based)
• Include state management (Signals, NgRx, Akita)
• Mention testing coverage and tools used
• Showcase performance optimizations (lazy loading, SSR)

Glossary of Terms

• AOT — Ahead-of-Time compilation, compiles templates at build time
• DI — Dependency Injection, Angular's way of providing dependencies
• NgModule — A class that groups components, directives, pipes, and services
• Standalone — A component/directive/pipe that does not belong to an NgModule
• Signal — A reactive primitive that tracks state and notifies consumers
• RxJS — Reactive Extensions for JavaScript, used for asynchronous streams

Q&A

Q: Should I use NgModules or standalone components for new projects?
A: Angular team recommends standalone components for new projects. NgModules are still supported but considered legacy.

Q: What is the best way to manage state in Angular?
A: For small apps, Signals or a simple service with BehaviorSubject. For larger apps, consider NgRx or Akita.
