Prerequisites & Setup 📋

Before diving into Angular development, let’s ensure you have the foundational knowledge and tools needed to get the most out of this comprehensive tutorial.

🎯 Required Knowledge

JavaScript/TypeScript Fundamentals

You should be comfortable with:

JavaScript ES6+ Features:

• Arrow functions and function expressions
• Destructuring assignment
• Template literals
• Modules (import/export)
• Promises and async/await
• Classes and object-oriented programming

TypeScript Basics:

• Type annotations and interfaces
• Generics (basic understanding)
• Union types and optional properties
• Working with TypeScript in Angular projects

Web Development Fundamentals

HTML & CSS:

• Semantic HTML elements and structure
• CSS selectors, flexbox, and grid
• Responsive design principles
• Basic understanding of SCSS/Sass (helpful)

HTTP & Web APIs:

• Understanding of REST APIs
• HTTP methods (GET, POST, PUT, DELETE)
• JSON data format
• Basic authentication concepts

Angular Knowledge (Optional)

If you’re new to Angular, don’t worry! We’ll teach you everything from scratch. However, if you have some experience:

Helpful Angular Concepts:

• Components: Basic component structure
• Templates: Data binding and event handling
• Services: Dependency injection basics
• Modules: NgModules (we’ll transition to standalone)
• CLI: Angular CLI commands

Advanced Concepts (We’ll Cover These):

• RxJS and Observables
• Reactive forms and validation
• Advanced routing patterns
• State management
• Testing strategies

🛠️ Development Environment

Required Software

Node.js (Version 18+)

# Check your Node.js version
node --version

# Should output v18.0.0 or higher

Angular CLI (Latest Version)

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

# Check version
ng version

Code Editor We recommend Visual Studio Code with these extensions:

• Angular Language Service
• TypeScript Importer
• Prettier - Code formatter
• Auto Rename Tag
• Bracket Pair Colorizer

Optional but Helpful

Browser Extensions:

• Angular DevTools (Chrome/Firefox)
• Redux DevTools (for state debugging)

Online Development:

• StackBlitz account (for running examples online)
• CodeSandbox account (alternative online IDE)

🧠 Conceptual Prerequisites

Reactive Programming Basics

While not strictly required, understanding these concepts will help:

State Management:

• What is application state?
• The difference between local and global state
• Why state management matters in complex applications

Reactive Programming:

• The concept of “reactive” updates
• Push vs pull-based systems
• The observer pattern (basic understanding)

Angular’s Evolution

Understanding Angular’s Journey:

• Why Angular introduced signals
• The relationship between RxJS and Signals
• The concept of “fine-grained reactivity”

✅ Knowledge Check

Before proceeding, assess your readiness:

JavaScript/TypeScript Fundamentals

• Create and use arrow functions
• Destructure objects and arrays
• Use template literals for string interpolation
• Work with Promises and async/await
• Understand basic TypeScript types (optional)

Web Development Basics

• Create HTML structure and forms
• Style elements with CSS
• Understand HTTP requests and responses
• Work with JSON data
• Basic understanding of web security

Development Environment

• Have Node.js 18+ installed

• Comfortable with terminal/command line

🚀 Quick Setup Test

Let’s verify your environment is ready:

# Create a test Angular project
ng new angular-test --routing=true --style=scss --skip-git

# Navigate to the project
cd angular-test

# Serve the application
ng serve

If you can see the default Angular welcome page at http://localhost:4200, you’re ready to go!
