Angular: Why It's in Demand, Why You Should Use It, and How to Get Started (Angular 101)

Angular is often spoken of in the same breath as other front-end frameworks like React and Vue.js—but what exactly makes Angular stand out in the world of web development? Why is it still a go-to choice for enterprise-level applications, and how can a developer get started with it today?

In this post, we’ll dive into what Angular is, why it’s in high demand, who is using it, and give you a practical introduction to Angular basics—perfect if you’re just starting or considering adding it to your tech stack.

🔍 What is Angular?

Angular is a TypeScript-based open-source web application framework developed and maintained by Google. It was launched in 2016 as a complete rewrite of the original AngularJS (which came out in 2010). This newer version, often just referred to as Angular, is built for building scalable, single-page client applications using HTML, CSS, and TypeScript.

Unlike lightweight libraries such as React, Angular is a full-fledged framework—it comes with batteries included: routing, state management, form handling, HTTP client, dependency injection, and more.

💼 Why Is Angular So In-Demand?

1. Enterprise-Grade Support

Angular has strong adoption in large-scale, enterprise environments. Banks, healthcare platforms, government applications, and internal dashboards often use Angular because of its opinionated structure, long-term support, and scalability.

2. Backed by Google

Angular is maintained by Google, which means continuous improvements, long-term viability, and widespread community support.

3. Consistency and Structure

In Angular, there's a "right" way to do things. Unlike flexible libraries, Angular enforces architecture via modules, components, and services—making it easier for large teams to collaborate without falling into chaos.

4. TypeScript by Default

Angular is built with TypeScript, which brings static typing, better tooling, and fewer bugs during development—something enterprise clients love.

5. Rich Ecosystem

The Angular ecosystem is vast. You have official tools like Angular CLI, Angular Universal (server-side rendering), and Angular Material (prebuilt UI components). The framework also integrates well with testing libraries, REST APIs, and cloud platforms.

🚀 Why Use Angular?

• Structured development: Everything from routing to testing is built-in.

• Two-way data binding: Keeps the model and the view in sync easily.

• Built-in DI (Dependency Injection): Makes code modular and testable.

• Cross-platform development: Angular can be used for web, mobile, and even desktop applications (via NativeScript or Ionic).

• Large community: Tons of tutorials, libraries, job opportunities, and Stack Overflow answers.

Angular might have a steeper learning curve than React or Vue—but its payoff is powerful for building robust applications at scale.

🧠 Angular 101: Getting Started

Let’s now go over the basics of Angular for newcomers.

✅ Prerequisites

Before starting with Angular, you should be familiar with:

• HTML & CSS

• JavaScript (ES6+)

• TypeScript (basic understanding)

1. Install Angular CLI

Angular CLI is a command-line interface tool that helps scaffold and manage Angular applications.

npm install -g @angular/cli

2. Create a New Angular App

ng new my-angular-app
cd my-angular-app
ng serve

Visit http://localhost:4200 in your browser to see your new app running.

3. Understanding the Angular File Structure

src/
  app/
    app.component.ts       → logic for the root component
    app.component.html     → template
    app.component.css      → styles
    app.module.ts          → root module
  assets/                  → static files
  index.html               → entry point

4. Core Concepts

Here are a few fundamental concepts in Angular:

✔ Components

The building blocks of any Angular app. Each piece of the UI is a component.

@Component({
  selector: 'app-hello',
  template: `<h1>Hello, {{name}}</h1>`
})
export class HelloComponent {
  name = 'World';
}

✔ Modules

Angular apps are modular. The @NgModule decorator helps group components, services, and directives.

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule],
  bootstrap: [AppComponent]
})
export class AppModule {}

✔ Services & Dependency Injection

Logic like data fetching or business rules go in services, which are injected where needed.

@Injectable({ providedIn: 'root' })
export class DataService {
  constructor(private http: HttpClient) {}

  fetchData() {
    return this.http.get('/api/data');
  }
}

✔ Routing

For single-page apps, Angular Router allows navigation between components.

const routes: Routes = [
  { path: '', component: HomeComponent },
  { path: 'about', component: AboutComponent }
];

📈 What You Can Build With Angular

• Admin dashboards

• Healthcare apps

• E-commerce platforms

• Banking portals

• ERP and CRM systems

• Progressive Web Apps (PWAs)

🛠️ Angular vs Other Frameworks

finally...

Angular might not be the trendiest framework in 2025, but its stability, scalability, and structure make it a solid choice for developers and companies who need long-term maintainability and enterprise-level performance. With Angular 17 introducing performance improvements, standalone components, and better DX (developer experience), there’s never been a better time to dive in.

If you're looking to work in environments that demand clean architecture, type safety, and modular design, Angular is a must-have in your toolbox.
