AngularJS Tutorial

The JavaScript Framework AngularJS is really powerful. It is employed in projects for Single Page Applications (SPA). It adds new characteristics to the HTML DOM, extending it, and improving user interaction. Numerous developers choose AngularJS since it is open source, totally free, and available everywhere. It is distributed under the Apache License 2.0.

What is AngularJS?

AngularJS refers to an open-source framework for web applications that were created by Misko Hevery and Adam Abrons in 2009. Google currently looks after it. The most recent version is 1.2.21. The effective framework AngularJS allows developers to design client-side JavaScript applications in a neat Model View Controller (MVC) manner, enabling the development of Rich Internet Applications (RIAs). Cross-browser compatibility applies to AngularJS applications. JavaScript code optimized for each browser is handled by AngularJS automatically.

Features of AngularJS:

The effective framework AngularJS allows developers to design client-side JavaScript applications in a simple Model View Controller (MVC) manner, enabling the development of Rich Internet Applications (RIAs). Cross-browser compatibility applies to AngularJS applications. Each browser’s compatible JavaScript code is handled automatically by this. Some of the top features include:

1. Data-binding:

It is the process through which model and view components automatically synchronize data.

2. Scope:

These are model-referential items. Between controller and view, they serve as an adhesive.

3. Controller:

These are JavaScript functions that are restricted to a certain scope.

4. Services:

AngularJS has a number of built-in services, such $http for creating XMLHttpRequests. These are singleton objects that the program only creates once.

5. Filters:

These take an array and choose out a subset of the entries, returning a new array.

6. Directives:

On DOM components like elements, attributes, CSS, and more, directives serve as markers. These may be utilized to develop unique HTML tags that act as fresh, original widgets. The built-in directives in AngularJS include ngBind, ngModel, etc.

7. Templates:

These are the displayed views that contain data from the model and controller. These can be several views on the same page using partials or a single file (like index.html).

8. Model View Whatever:

Model, View, and Controller (or MVW) is a design pattern for segmenting applications into independent components that each have specific functions. Instead of implementing MVC in the conventional sense, AngularJS uses something more like MVVM (Model-View-ViewModel). It is affectionately referred to as Model View Whatever by the Angular JS team.

9. Deep Linking:

To enable bookmarking, deep linking allows the application state to be encoded in the URL. After that, the URL may be used to return the program to its original condition.

10. Dependency Injection:

An integrated dependency injection subsystem in AngularJS makes it simple for developers to design, comprehend, and test applications.

Career path for an AngularJS Developer:

Basic Angular developer Skills

1. npm

Nowadays, the Node Package Manager (npm) is essentially a necessary tool for all web developers. Npm is the main tool used to install hundreds of client-side web development packages, including Angular, even if you’re not performing Node.js development. The entire Angular framework is split up into many npm packages, and it’s highly probable that you’ll ultimately need to install other helpful, non-Angular packages as well. Therefore, it is useful to know how to install what you need when you need it.

2. Angular CLI

The Angular CLI is the first Angular package that you need to install using npm (Command Line Interface). Although installing individual Angular packages and writing all the configuration code by hand is absolutely doable, using the CLI streamlines the process and guarantees that your project will follow industry best practices. The advantages of utilizing the CLI go beyond just building new applications.

Further, it may also be used to expand an existing app with additional features, services, modules, and more. This will save you a tonne of typing, ensuring that you adhere to the Angular coding standards, and ensure that you don’t overlook the minor details that might make the difference between working code and hours of frustrating head-scratching.

3. HTML and CSS

The necessity for a deep understanding of the most fundamental web development technologies is still necessary despite the existence of frameworks like Angular. Although Angular gives you the building blocks you need to create quick, useful applications, such applications still need to be displayed in a browser, which necessitates creating user interfaces with HTML and CSS. While Angular Material and other style libraries are excellent at assisting you in producing attractive apps rapidly, you must be aware of when and where to make adjustments in order to obtain the precise appearance you desire.

4. Angular Application

It will take some time to master all the many components of Angular and how they function together because it is a massive framework. The good news is that you don’t need to be an expert to begin creating helpful applications. Forms, modules, components, and services are necessary for almost every Angular application. Learn how to combine and integrate these elements, and you’ll have the knowledge needed to create commercial applications with all the features you need. Additionally, you’ll be equipped with a strong foundation for future study and the application of more complex solutions.

5. TypeScript

TypeScript, a superset of JavaScript, is the programming language used to create Angular. It’s the language that is advised for Angular app development. There are many benefits to using TypeScript rather than JavaScript, but fewer problems and an improved capacity for confident code refactoring are at the top of the list. Utilizing strong typing will ensure that you and your team are using variables and functions in the way that they were meant to be used. Any sizable codebase will surely experience a reduction in defects as a result. Additionally, by securely refactoring your code using TypeScript’s strength, your app will be able to grow and develop as your users’ needs do.

6. RxJS

Reactive programming using observable streams is supported by the package RxJS. Although it is separate from Angular, it is included with the framework and is used for many typical activities including sending HTTP requests for data Observables and other RxJS capabilities are used by Angular to provide a uniform API for carrying out asynchronous actions.

7. Git

Without source control, even basic programs may be built in a dangerous manner. Git allows you to confidently experiment with new application features and coding styles, much as TypeScript enables you to do with your code. You have the flexibility to test out wild ideas or create a proof of concept that your users could find useful when you know you can quickly and simply utilize your Git repository to go back to a prior (functioning!) version of your code.

8. Empathy

Having compassion for other developers is also crucial. It’s difficult to work as a software engineer. Keeping up with the ever-changing tools and technology may be challenging. Keep in mind that each developer on your team brought a unique set of abilities and experiences to the table. Spend some time thinking about that and identifying the ways you might collaborate and support one another to produce excellent software.

Salary of Angular Developer:

The benefits are excellent for Angular developers. According to Payscale, the typical Angular developer pay in the US is $72,348 per year. The average Angular front-end developer income in India, according to Glassdoor, is Rs. 553,610.
