How to Learn Angular? - A Comprehensive Guide
Table of Contents
Before proceeding further, one important thing that you should be clear about is that we are talking about the Angular framework, which represents the Angular version2 and above. The first-ever version of Angular is known as AngularJS and is quite different from Angular.
In all, if you want to master Angular, you will need serious determination and perseverance, especially if you are an aspiring web developer.
Whether you are looking for some good reasons to learn Angular or want guidance on how you can start learning Angular, you have landed just at the right place. This detailed blog covers all the essential aspects that one should know for learning Angular effectively. So, without wasting any more time, let’s get started.
Why Should You Learn Angular?
A beginner who is willing to build a promising future in web development must have suggestions to learn Angular. Also, you may have wondered if it would be a good idea to learn Angular in the first place.
To be honest, there is no straightforward answer to this as it completely depends on your requirements. For instance, if you are ready to go through a challenging learning experience, and want to code and manage projects in a highly organized manner, then Angular can be your best pick.
Here are some of the key features of Angular that often become the reasons why many geeks pick this leading JS framework as their tool of choice for front-end development:
1. Ideal for Developing SPAs (Single-Page Applications)
Building responsive and high-performance single-page applications become easier with Angular. If you don’t know, a SPA is a web application that does not require loading multiple HTML pages as all the data and content are injected dynamically in a single HTML page. The content or elements are displayed or removed according to the user’s actions on the page.
Single-page applications are extremely fast, easy to develop and debug, highly reusable, and offer a better user experience. All these characteristics have made SPAs a popular choice among businesses and developers alike. Angular streamlines the process of developing SPAs, making this framework of great value for developers.
2. Better Management With Components
Angular helps you to streamline the process of web development and also allows sound management of all the application code through components. A component is considered to be the basic building block of an Angular application. Every component has 3 main elements that are:
- An HTML Template: defines the structure of the component that is to be rendered within the app,
- A CSS Stylesheet:decides the look and feel of the component, and
- A TypeScript File: This contains the code that defines the behavior of the component.
Usually, a component is created for each application to make it easier to keep the whole application well-organized and easy to manage.
3. Quick Production with the Angular CLI
Creating the basic structure of an Angular application and even adding new components and services could have been quite difficult and time-consuming without the Angular CLI.
With the Angular command-line interface, creating a new project with all the basic dependencies, files and directories are just a command away. To create a new project, you simply need to use the ng new command followed by the project's name.
Also, you can easily add new components and services to your project by simply executing single-line commands in the Angular CLI. Also, you can build your Angular app, run it on a local server, and do more by using various Angular CLI commands. All this leads to quicker app production and ensures more focus on writing code rather than setting up project files.
4. Animation Support
With Angular, one can build modern apps with a myriad of functionalities. However, there’s one more thing that you can add to your apps without any significant challenge, and that is animation. Angular comes with native support for complex animations that allow you to enhance your apps' overall appearance and user experience.
The animation API offered by the JS web framework is easy to use and offers a variety of functions. So, you can introduce animations in the various sections of your app that tend to gain users' attention and prompt them to engage with the app in a better way.
5. Cross-Platform Framework
Being a cross-platform framework is one of the most notable reasons for developers to shower Angular with love. It not only lets you create innovative and progressive web applications but also native mobile apps as well as desktop apps.
By gaining the knowledge and experience working with Angular, you can create applications for almost all the major platforms, be it Android, iOS, Windows, macOS, or Linux. Surely, you have to take assistance from various other technologies, but Angular will play a pivotal role in developing apps for these platforms right from scratch.
This feature gives you the flexibility to expand your horizons when it comes to app development. Also, all this concludes that Angular is one of the most power-packed and versatile JS frameworks out there.
6. Type Checking Minimizes Coding Errors
TypeScript is a strongly typed language that allows you to declare the type of variables and data structures. This allows the detection of errors before the code enters execution. The type of declared variables and data structures are validated in runtime so that no conflicts occur later during code execution.
In all, TypeScript allows faster development and, at the same time, reduces the chances of errors in code that come in handy, especially when creating large and complex applications.
So, these are some of the most common reasons that make Angular a viable choice for developing top-notch applications. Now, if you have decided to learn the popular JS framework, it's time to move forward and see how you can actually embark on the journey to become an Angular developer.
Prerequisites for Learning Angular
Angular is widely used for web development, and there are certain requirements that you must meet to learn Angular. By checking off all the prerequisites, you can make sure that you proceed in the right direction and learn the popular web framework in the best possible way. The prerequisites for learning Angular are as follows:
- The basic idea of the MVC (Model-View-Controller) architecture.
- Basic knowledge of Node.js and npm (Node Package Manager).
- Experience working with the command line.
- Exposure to TypeScript.
Nonetheless, as soon as you meet all the requirements stated above, take a step ahead and choose an IDE to work with Angular.
As you might already know, the need for a source code editor for writing code and an IDE (Integrated Development Environment) comes with it. Also, IDE combines various tools and features, including a debugger, compiler, version control, code completion and refactoring, and syntax highlighting that makes it a complete package for developing, testing, and deploying apps.
You can undoubtedly use a dedicated source-code editor like Visual Studio Code or Atom to write Angular code. Still, eventually, you may need to switch to an IDE to ensure faster and efficient development. So, it would be a little better to start your journey with some IDE; else, you can go with a source-code editor too.
Below are 3 of the most popular IDEs to use for Angular development:
1. Angular IDE
Anyone looking for a dedicated IDE for Angular can consider using Angular IDE. It is one of the most powerful IDEs out there for developing Angular applications of any scale.

So, if you are ready to test your learning and need some good project ideas to work on, don’t worry; we’ve got you covered. Following are some of the most popular Angular projects that you can consider working on to gain hands-on experience:
1. Notepad Web Application
This is one of the simplest Angular projects that are quite popular among beginners. The Notepad application allows users to create, modify, and delete notes. It is completely up to you how you want to sort the notes, but it is advisable to organize them per the time they’ve been added or modified.
While working on this project, you can either use mock APIs or create a backend with Node.js and use MongoDB as your database. This is important because the notes data you’ll create need to be accessed and rendered within the app using REST APIs. This will also help you to become familiar with the backend development using Node.js and MongoDB.
2. Chat App
Chat applications are highly popular, and Angular is a preferable choice for making a fully functional chat app, but as a beginner, you need to create a simple chat app to learn how things work. Once you get a good idea of how things work, you can add more functionality to your chat app.
While creating a chat app, you need to use concepts like services, dependency injection, RxJS, observables, and more. Your chat app should allow two users to connect and send messages in real-time. Also, create a server that will establish a connection between users and deliver messages.
If you want to make this project a bit more challenging and interesting, you can add functionalities like user login and authentication, chat rooms, etc. You can use popular libraries like socket.io to enable your chat app with real-time, event-based communication.
3. Simple Blogging App
As a beginner, this is another project that you will love working with. The concept of a blogging app is straightforward; it should allow users to add, delete, modify blogs having a title and the main content. Creating a basic blogging app is quite easy, but you will be implementing many Angular concepts, which is why this project can prove advantageous for you.
While developing this app, allow users to create and log in to their accounts to add blogs. Create an admin account that will be responsible for managing users and their content. The admin should have the authority to remove the content of other users.
To create the blogging app, you have to use various fundamental concepts of Angular, including form validation, services, pipes, routing and navigation, HttpClient, etcetera. Also, you need to enable CRUD operations in your app to deal with the blog data, such as adding or modifying blog content.
4. Responsive Admin Dashboard
The next project that we have is a responsive admin dashboard that can display an array of information handy for managing an online store, a marketing tool, etc. The basic purpose of an admin dashboard is to collect the desired data and display it in such a way that the admins can use it to make informed decisions.
But before you start working on this project, understandthat this project is complicated and challenging. So, it would be better to work on this project if you have already worked on a few Angular projects.
You can build an admin dashboard for an online store that sells some sort of product. So, the information that you need to track and display within the admin panel would be the number of visitors, products sold, sources of traffic, total revenue generated, etc. Also, you can use bar charts, pie charts, etc., to display the data in a meaningful way.
Once you have done all your basic learning about Angular, your next aim would be to grab a well-paying job. For that, your knowledge alone about the technology is not going to be enough. So, what you need is a valid certification that will attest to your skills and achievements.
