Angular Certification Linkedin: Angular

Frontend

Looking for angular certification linkedin training? A TypeScript-based web application framework developed by Google for building dynamic, scalable single-page applications (SPAs) with rich user interfaces.

What is Angular?

Framework Overview

Angular is a complete rewrite of AngularJS, built with TypeScript and designed for enterprise-scale applications. It provides a comprehensive solution for frontend development with built-in features for routing, forms, HTTP client, and more.

Key Features

  • TypeScript: Built with and for TypeScript
  • Component-based: Modular architecture
  • Dependency Injection: Built-in DI system
  • CLI Tools: Powerful command-line interface
  • Two-way Data Binding: Automatic UI updates

Angular Architecture

Components

The basic building blocks of Angular applications. Each component controls a patch of screen called a view and consists of a TypeScript class, HTML template, and CSS styles.

Services & Dependency Injection

Services provide specific functionality not directly related to views. Angular's DI system makes services available to components efficiently and testably.

Modules

NgModules help organize an application into cohesive blocks of functionality. Every Angular app has at least one module, the root module.

Routing

Angular Router enables navigation from one view to another as users perform application tasks, supporting lazy loading and route guards.

Basic Angular Component

Component Example

// user.component.ts
import { Component, OnInit } from '@angular/core';
import { UserService } from '../services/user.service';

@Component({
  selector: 'app-user',
  templateUrl: './user.component',
  styleUrls: ['./user.component.css']
})
export class UserComponent implements OnInit {
  users: User[] = [];
  selectedUser: User | null = null;

  constructor(private userService: UserService) { }

  ngOnInit(): void {
    this.loadUsers();
  }

  loadUsers(): void {
    this.userService.getUsers().subscribe(
      users => this.users = users,
      error => console.error('Error loading users:', error)
    );
  }

  selectUser(user: User): void {
    this.selectedUser = user;
  }
}

Users

{{ user.name }} - {{ user.email }}

User Details

Name: {{ selectedUser.name }}

Email: {{ selectedUser.email }}

Role: {{ selectedUser.role }}

Angular vs Other Frameworks

Angular vs React

  • Angular: Full framework, opinionated structure
  • React: Library, more flexible but requires additional tools
  • Angular: TypeScript by default
  • React: JavaScript with optional TypeScript

Angular vs Vue.js

  • Angular: Steeper learning curve, enterprise-focused
  • Vue: Gentler learning curve, progressive adoption
  • Angular: More built-in features
  • Vue: Simpler, more lightweight
