When AngularJS was launched in 2010, it revolutionised web development by introducing a robust framework for building dynamic web applications. But today it is Angular-X you need to use.
Angular 2.0 was introduced in 2014. It introduced a shift from JavaScript to TypeScript and required a complete rewrite of the code for applications developed in AngularJS, which created controversy among developers. The final version was released in 2016. However, the old version took on a life of its own and continued to be developed. Since 2022, there has been no support or development for AngularJS.
The new version, on the other hand, has been developed and is currently available in version Angular 19. However, it is often referred to as Angular-X to distinguish it from the previous version. Many have not yet made the transition to the new technology, and when checking online, one finds that the number of those remaining in the old unsupported version is surprisingly large.
Leaving AngularJS not only means keeping up to date with the latest technology, but also taking advantage of improved performance, security and maintenance. Here are some of the main reasons why it’s time to make the move.
Improved performance and speed
One of the most noticeable improvements is performance. This is because it is built with a new architectural approach that drastically improves loading times and application speed. By using a compiler that pre-compiles templates into highly efficient JavaScript code, execution time is reduced compared to the old version. This results in faster rendering and a more responsive user experience, which is crucial for keeping users engaged.
Modern and modular architecture
Angular X introduces a modular architecture that facilitates application development and maintenance. While the old version used a monolithic structure, the newer versions divide the application into distinct modules that can be developed, tested, and maintained independently of each other. This modular architecture makes it easier to manage large code bases and improves code reuse and team productivity.
Improved security
Security is a critical aspect of modern web development, and the new versions offer stronger protection against common security issues. With built-in support for security features such as DomSanitizer and Content Security Policy (CSP), the risk of cross-site scripting (XSS) and other attacks is reduced. This ensures that your applications are safer for users and minimises vulnerabilities that could be exploited by malicious actors.
Active support and future updates
An important factor to consider is the support from the developer community and updates from the framework’s creators. Google announced quite some time ago that it would gradually phase out support for AngularJS, which has now happened at the end of 2021. This means that no one is fixing bugs and security issues anymore. For those who still use AngularJS, this will lead to problems in the long term. Migrating to the new version provides continuous updates, new features and improvements, allowing you to keep your applications modern and competitive.
Not upgrading can mean compatibility challenges with modern browsers, lower performance and increased security risks, i.e. an increased risk of hacker attacks and non-compliance with GDPR, NIS2 or DORA.
Improved developer experience
The newer versions offer a more developer-friendly environment. Type Script, for example, provides static type checking and better tool support. This makes coding and debugging easier and more efficient. Tools such as Angular CLI (Command Line Interface) help to quickly create, build and test applications, which speeds up the development process and reduces the risk of errors.
Summary
Leaving AngularJS and transitioning to a newer version is an important step for companies that want to ensure their applications are modern, secure, and maintainable. AngularJS, once a groundbreaking technology, has now reached the end of its life cycle, meaning that it is no longer supported or receiving updates. This means that applications built with AngularJS are vulnerable to security issues and that their maintenance and development are becoming increasingly costly and inefficient.
However, migrating and upgrading to Angular 2+ not only means avoiding security risks and technical debt, but also taking advantage of new features, improved performance and a more robust architecture. Angular is continuously evolving to meet modern development needs, and with its broad ecosystem and strong community, it offers a future-proof platform for web application development.
A well-planned migration strategy can minimise disruption and ensure a smooth transition, allowing businesses to continue creating continuous value for their users. With the right expertise and planning, a transition to a more modern platform can contribute to increased efficiency, improved user experience and long-term sustainability for your application.
