Tired of running in circles like a hamster in a wheel, with messy code and slow development? Look no further than Angular, the superhero of JavaScript frameworks. 

Developed by Google, Angular is loved worldwide for its ability to create efficient single-page applications. But that’s not all! It also makes your web development faster and less stressful. 

Sounds too good to be true?!

That’s what I thought when I started learning Angular, but don’t worry. In this guide, I’ll take you through every Angular feature, including easy-to-use directives, two-way data binding, modular development, and more. 

By the time you finish reading this article, you’ll become an Angular master ready to take on the World Wide Web!

Understanding Angular’s past to leverage its full potential

The story of Angular isn’t as ancient as the Romans, but it sure is equally transformative. 

Initially named AngularJS, this JavaScript framework gained immense popularity in 2010, revolutionizing web development. However, like a Hollywood star undergoing a makeover, Angular went through a significant transformation. In 2016, it dropped the “JS,” underwent an entire revamp, and emerged as simply “Angular” which we all love and adore.  

The motive behind this change was to broaden its horizons beyond being just a JavaScript framework and support other languages like TypeScript and Dart. This upgrade gave Angular not only a shiny new appearance but also added powerful features that make developers’ lives so much simpler.

Mastering the basics of Angular 

Many of those powerful features wouldn’t be possible without Angular’s core concepts:

  1. Components — Small, self-contained sections of code that control a chunk of your webpage. Like LEGO blocks, you build your app by sticking these components together.
  2. Directives — A way to guide and modify the behavior of your webpage elements like an orchestra conductor wielding a baton over their musicians. They’re like magic wands from a Harry Potter movie, making your webpage dance to your spell.
  3. Modules — In the dev community, also go by containers that hold related components, directives, and services. They are like “Big Brother” in Angular development overseeing everything. Think of them as an organized bookshelf keeping your applications neat and manageable.

Fun Fact: Did you know that those three Angular concepts were the Big Bang of the Angular library universe? Every Angular library, such as Angular Material, Onsen UI, or PrimeNG, has some form of a curated collection of those concepts.

Why Angular? 3 unique Angular advantages in web development

Let’s talk business: Why should you choose Angular for web development? There are dozens of other different web development frameworks equally powerful!

When I started dipping my toes in web development after being a  software developer for more than a decade, these three unique advantages fascinated me Angular: 

  • TypeScript usage — Consider TypeScript your Swiss Army knife in the world of JavaScript. This superset of JavaScript is statically typed, making it excellent for large-scale projects. It’s like having a personal bodyguard for your code, checking and eliminating potential errors on-the-fly.
  • Two-way data binding — Ever wished for telepathy? With Angular’s two-way data binding, it’s possible (well, for your code, at least)! Changes in the model reflect in the view and vice versa. It’s the secret ingredient to creating dynamic and interactive user interfaces with Angular.
  • MVVM Architecture — In the land of Angular, the Model-View-ViewModel (MVVM) architecture is king. It separates your application logic from the UI, making your code cleaner and more maintainable. Plus, developers can work separately on the same app section, boosting productivity!

I then realized: working with Angular is like working with a seasoned team on your web development project. Everything is reliable, efficient, and fast!

Step-by-step guide on setting up your Angular development environment

Okay, you’ve got the basics and unique features down, but how do you tap into Angular’s potential?

Setting up your Angular development environment is easier than assembling an IKEA table with these three simple steps:

  1. Install Node.js and npm — Think of Node.js as the electricity and npm as the plug socket for your Angular environment. Install Node.js from its official website, and voila! You get npm (Node Package Manager) bundled with it!
  2. Get Angular CLI — Angular CLI is your superhero toolset for developing in Angular. Summon this tool by running “npm install -g @angular/cli” in your terminal or command prompt.
  3. Celebrate — That’s it! Your Angular development environment is now good to code! 

But don’t pop up the champagne just yet. Our Angular web development journey is far from over!

A practical walkthrough to building your first Angular web app

Now comes the big moment — your first Angular web application code!

But don’t worry. It’s not as hard as it seems. It first starts with:

  • Running the “ng new my-first-app” command. Think of this command as the entry ticket into the Angular world
  • Next, navigate to your project directory with “cd my-first-ap“. Those Linux-based software devs will immediately recognize what this means. 
  • Add the following code to your “app.component.ts” file:

import { Component } from ‘@angular/core’;

@Component({

  selector: ‘app-root’,

  template: `<h1>Hello, Angular world!</h1>`,

  styleUrls: [‘./app.component.css’]

})

export class AppComponent {

  title = ‘my-first-app’;

}

  • Run the app with the “ng serve –open” command.
  • Tap yourself on the shoulder while affirming what a great Angular web developer you are, because you just made your first Angular web application!

Adopting best practices for superior Angular web apps 

You’ve probably heard the saying: “With great power comes great responsibility!“. It rings especially true for Angular development! 

That’s why adopting the best Angular development practices can make your code cleaner, more efficient, and easier to debug. Think of it like decluttering your garage for a speedy car getaway.

Here are some essential best practices I’ll give you to follow (make sure to print them out and use them as an Angular pocket-like-Bible):

1. Coding Standards — Use Angular’s style guide as your go-to resource for coding standards. These rules aren’t there to hold you back but rather provide structure and clarity, much like traffic rules prevent road chaos.

2. Design principles — Keep it DRY (Don’t Repeat Yourself), and strive for reusable components and services to maximize efficiency. It’s like preparing a big batch of pasta sauce that’s been used multiple times!

3. Performance optimization — Ever heard of “Lazy Loading“? This method loads components only when they’re needed instead of loading everything upfront. The result is faster application start times and smoother user experiences!

Angular in real-world web action

Hopefully, you’ve noted those best practices down because now, you’re going to put them to the test! 

With these real-world Angular projects you’ll see what it truly means to become an Angular web developer and what type of exciting applications you get to build:

  • Google’s Firebase Console — Utilizing their framework is no surprise from giant Google. Firebase offers user-friendly app development tools, and its entire console is built using Angular.
  • Microsoft Office Home — Believe it or not, Angular has even made its way into the home of Microsoft Office. It powers dynamic, interactive features on their homepage, driving user engagement.
  • IBM’s Watson — Even the AI powerhouse Watson uses Angular for creating visually appealing front-end interfaces promoting user engagement.

Besides scalability and flexibility, that’s just the tip of the what-Angular-can-do-in-real-world type of iceberg!

Is Angular going to take over the Internet? 

Just like our furry hamster friend from the introduction, you’ve been sprinting. But instead of spinning in circles, you’ve mastered this powerful Google-driven JavaScript framework

But remember this: With Angular in your development arsenal, you’re not just another coder. You’re the Man of Steel of web development, ready to create fast, efficient, and robust applications. 

So wear your “S” proudly, step into the limelight, and embark on your Angular journey today!
