Master Advanced Angular Techniques for Skillful Development


Angular has emerged as one of the most powerful and popular front-end frameworks for building dynamic and scalable web applications. While mastering the basics of Angular is essential, delving into advanced techniques can take your development skills to the next level. In this article, we'll explore some advanced Angular techniques and provide code examples to help you elevate your Angular development expertise.

Lazy Loading Modules

Lazy loading modules is a powerful technique for optimizing the performance of your Angular applications. By loading modules asynchronously only when they are needed, you can reduce initial load times and improve the overall user experience. In Angular, lazy loading is achieved by configuring the routing module to load specific modules on demand.

Let's take a look at an example.

const routes: Routes = [
  { path: 'dashboard', loadChildren: () => import('./dashboard/dashboard.module').then(m => m.DashboardModule) },
  { path: 'profile', loadChildren: () => import('./profile/profile.module').then(m => m.ProfileModule) },
  { path: 'settings', loadChildren: () => import('./settings/settings.module').then(m => m.SettingsModule) }

Dynamic Component Creation

Angular provides powerful tools for dynamically creating and rendering components at runtime. This can be particularly useful when building complex user interfaces or implementing dynamic content. One common use case for dynamic component creation is when working with modal dialogs or pop-up windows.

Here's how you can dynamically create and render a component in Angular.

import { Component, ComponentFactoryResolver, ViewChild, ViewContainerRef } from '@angular/core';
import { MyDynamicComponent } from './my-dynamic.component';

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  @ViewChild('dynamicComponentContainer', { read: ViewContainerRef }) container: ViewContainerRef;

  constructor(private resolver: ComponentFactoryResolver) {}

  createComponent() {
    const factory = this.resolver.resolveComponentFactory(MyDynamicComponent);
    const componentRef = this.container.createComponent(factory);

Advanced Routing Techniques

Angular's powerful routing capabilities extend beyond basic route configuration. Advanced routing techniques such as route guards, resolvers, and nested routes can add additional layers of functionality and security to your applications.

Let's explore how you can implement route guards to protect routes based on user authentication status.

import { Injectable } from '@angular/core';
import { CanActivate, ActivatedRouteSnapshot, RouterStateSnapshot, Router } from '@angular/router';
import { AuthService } from './auth.service';

  providedIn: 'root'
export class AuthGuard implements CanActivate {
  constructor(private authService: AuthService, private router: Router) {}

  canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot): boolean {
    if (this.authService.isLoggedIn()) {
      return true;
    } else {
      return false;


Mastering advanced Angular techniques is essential for building robust, scalable, and efficient web applications. By incorporating lazy loading, dynamic component creation, and advanced routing techniques into your Angular projects, you can take your development skills to new heights and deliver exceptional user experiences. Keep exploring and experimenting with these techniques to unlock the full potential of Angular and stay ahead in the ever-evolving world of web development.
