What is AngularJS?

AngularJS is a model-view-controller (MVC) web framework that is used in the creation of dynamic and responsive web applications. AngularJS provides a modern alternative to the more traditional approach of using web forms to handle interaction with visitors to the web application. AngularJS is most commonly used to develop single-page applications due to its ability to dynamically refresh the page.

AngularJS is part of the JavaScript framework library, which is completely open-source. There are many free support resources online, which can mean it's easier to learn and report issues. It is regularly updated to incorporate new trends and needs in web development.

Features of AngularJS

The reason many web developers rely on AngularJS is that it is a platform with many positive features. Some top features of implementing AngularJS include:

  • MVC design: AngularJS is built following the design principle of MVC. Under this design, the data, logic and presentation layers of the framework are each isolated in their own section. This makes it easier to work on one without causing any disruption in the others.

  • Data binding: AngularJS automatically handles binding between the HTML code and the underlying data that generates it, making it easier to keep the data and display layers synced up. This means that if a change is made on the site, it can easily be used to update the underlying data, while a change to the data can be immediately reflected in the visual representation of the web platform.

  • Less code: The efficient approach that AngularJS brings to web functions means that the same tasks can be handled with less code than using combinations of other coding and scripting options. This reduces overall file sizes and saves programming time, as there is less to code.

  • Unit testing: The developers of AngularJS understand the importance of being able to run tests on code during the design process, so they also created a corresponding testing framework called Karma. The framework assists in the design and creation of unit tests for applications that use AngularJS.

  • Directives: When coding with AngularJS, a developer can include directives into elements on the page in order to incorporate specific behaviors. Adding directives to a web application increases is functionality and provides the developer with more options during the design process.

  • Expressions: By including code within double braces, a developer can add expressions to their code. This allows for the simple implementation of functions like math and concatenation of strings and numbers.

  • Filters: Converting data into the correct format is made easy with AngularJS through the use of filters that automatically convert the data into your chosen style. Filters are available for formats that include currency, dates, lowercase and uppercase letters and numbers as a string.

Because it is still being developed and updated, the feature list of AngularJS has the potential to continue expanding. As more features are added, the functionality and adaptability of AngularJS increase, making it a useful platform to work with.

Advantages of AngularJS

There are many benefits to working with AngularJS, which is why its popularity among single-page web developers is increasing regularly. Some top reasons to incorporate AngularJS into your web development plans include:

  • It's easier: The primary benefit of AngularJS is the ease of use. Working with AngularJS makes many of the tasks that a developer needs their pages to accomplish manageable with less code and in a more intuitive manner, helping them work more effectively and decrease build times.

  • It builds dynamic pages: Because the display and data layers of the application are automatically linked with AngularJS, it is ideally suited to creating sites that respond and update to inputs from the user dynamically. This is why the most common use for AngularJS is in the development of pages that handle multiple-step processes without loading multiple pages, with the page in use by the browser updating as needed.

  • It has vast open-source resources: There are already many existing projects for you to use as resources for your own project. In addition to assessing completed projects that accomplish tasks like yours and examining code to see how they completed them, there are also many excellent open-source resources available to you when you are looking to expand your knowledge or seeking a solution to a problem that you can't solve on your own.

  • It extends and customizes your HTML: Though developers were once able to build websites using just HTML, it's more common to need to use multiple languages to create a single page. AngularJS allows you to add directives to your HTML elements to extend their functionality and make the web applications you build more powerful and more useful to visitors to your site.

  • It provides options when testing: AngularJS provides you with choices as a developer when you are ready to test your application. If you prefer testing in pieces, it fully supports unit testing. If you instead would rather focus on the overall project, it allows for integration testing to determine if the different modules involved in your web application are communicating and working correctly.

  • It prepares you for the future: The technologies used for web design are always evolving. Although AngularJS will not always be a common element when building dynamic pages, it will still be a valuable skill to possess due to the likelihood that the next phase of web development will be built on the current standards. By refining your skills with AngularJS, you position yourself to be well-suited to learning the next framework.
