In this article, we’ll help you decide whether or not to make the transition from AngularJS to AureliaJS by highlighting their features, advantages and disadvantages, as well as exploring the five main benefits of choosing AureliaJS over AngularJS.
Before we can dive into the benefits of choosing AureliaJS over AngularJS, we need to understand what these two frameworks are, how they’re used and what their key benefits and differences are.
What is AngularJS?
What is AureliaJS?
Both AureliaJS and AngularJS follow a component-based architecture, which promotes modularity and reusability of code. Yet, they take different approaches to managing these components.
In AngularJS, components are created using directives, which are a way to extend HTML and create reusable UI elements. However, AngularJS directives can be complex and require a deeper understanding of the framework’s intricacies.
AureliaJS, on the other hand, simplifies component creation by using custom elements, which are native to the web platform. This approach is more intuitive and aligns with web standards, making it easier to create and reuse components across different projects.
An essential aspect of both frameworks, dependency injection helps developers manage dependencies between components, promoting modularity. However, AureliaJS offers a more straightforward and flexible dependency injection system compared to AngularJS.
In AureliaJS, the dependency injection container is highly configurable and can easily be extended to support various use cases. This flexibility enables developers to build more scalable and maintainable applications. In contrast, AngularJS’s dependency injection system can be more rigid and less accommodating to different project requirements.
Templating is another crucial aspect of web development, and both AureliaJS and AngularJS provide their own templating systems.
AngularJS uses a template syntax that mixes HTML with Angular-specific markups, such as directives and filters. This approach can be powerful, yet it can also have a steep learning curve which may be confusing for new developers.
AureliaJS’s templating system is more aligned with web standards, using custom elements, attributes and template literals. This approach simplifies the learning process for developers and ensures better compatibility with modern browsers and future web standards.
Community and ecosystem
The community and ecosystem surrounding a framework play a vital role in its adoption and success. AngularJS benefits from a large and mature community with numerous resources, libraries and third-party tools available. However, as AngularJS has been succeeded by Angular (2+), it’s essential to consider that the framework’s popularity and support may decline over time.
AureliaJS has a smaller but growing community of dedicated developers. The framework’s commitment to web standards, clean syntax and modular architecture has attracted developers looking for a more modern and future-proof solution. As the AureliaJS community continues to grow, so will the resources and ecosystem surrounding it.
Learning Curve and Developer Experience
The learning curve and overall developer experience can significantly impact a project’s success and the team’s productivity. AngularJS is known for its steep learning curve, particularly for developers new to web development or the framework itself. While this intricacy supports the creation of complex applications, it can also slow down development and increase the risk of errors or difficulties maintaining the codebase.
On the other hand, AureliaJS offers a more approachable syntax and adheres to web standards, making it easier for developers to learn and work with the framework. Its focus on simplicity and modularity allows for a more enjoyable developer experience and can lead to increased productivity and project success.
AureliaJS and AngularJS both have their strengths and weaknesses when it comes to performance. Firstly, AureliaJS is designed to be lightweight and modular, which makes it an excellent choice for developers looking to build fast and responsive apps. Its efficient rendering engine and data-binding system minimise the overhead associated with DOM manipulation and updates, leading to better performance in complex applications.
By comparison, AngularJS often struggles with performance, particularly in large-scale applications. The framework’s two-way data-binding mechanism, while powerful, can lead to performance issues when managing a large number of bindings. AngularJS’s digest cycle, which is responsible for detecting and propagating changes in the application, can occasionally cause bottlenecks.
Tooling and Ecosystem
The tooling and ecosystem surrounding a framework play a vital role in its adoption and success. AngularJS benefits from a large and mature ecosystem, with numerous libraries, plugins and third-party tools available to developers. However, as AngularJS has been succeeded by Angular (2+), it’s essential to consider that the framework’s popularity and support may decline over time.
AureliaJS has a smaller but growing ecosystem of tools and libraries. While it may not offer the same range of options as AngularJS, the framework’s commitment to web standards, clean syntax, and modular architecture has attracted developers looking for a more modern and future-proof solution. As the AureliaJS community continues to grow, so will the resources and ecosystem surrounding it.
Documentation and Learning Resources
Quality documentation and learning resources are crucial for developers to quickly adopt and effectively use a framework. As AngularJS has been around since 2010, there is a wealth of documentation, tutorials and other learning resources available online — support from friendly developers is also only a click away. However, the framework’s complexity can be difficult for newcomers to navigate, even with the resources available.
AureliaJS also offers extensive and well-organised documentation covering all aspects of the framework. While the number of learning resources may be fewer, those that are available are more focused and beginner-friendly. This accessibility makes it easier for developers to get started and become proficient with the framework.
Community and Support
AngularJS has an established and active community, which provides a wealth of knowledge and support for developers working with the framework. However, a key drawback is that Google discontinued support for the framework in early 2022, encouraging developers to transition to Angular (2+).
AureliaJS has a smaller but growing community of dedicated developers. The framework’s focus on simplicity, modularity and adherence to web standards has attracted developers seeking a more modern and sustainable solution. As the AureliaJS community continues to expand, so will the available support and resources.
In terms of upgradability, AngularJS is no longer supported by Google, so we will see no future updates. AureliaJS, with its emphasis on web standards and modular architecture, offers a more straightforward path for upgrading applications as new versions of the framework are released.
Use Cases and Real-World Examples
Developers have used AureliaJS in countless applications, including e-commerce platforms, content management systems and SaaS products. It’s suitable for small-scale projects and large enterprise applications thanks to its clean syntax, modular architecture and performance optimisations. Some examples of companies that have adopted AureliaJS include BTEA, the Bahrain Tourism and Exhibitions Authority and VNext, a global software development company.
AngularJS, being an older and more established framework, has been used in numerous real-world applications across various industries, such as Google, IBM and Microsoft. These businesses have leveraged AngularJS to build internal and customer-facing applications. However, it is important to remember that many organisations have started migrating to Angular (2+) or other modern frameworks as AngularJS has reached the end of its lifecycle.
Accessibility and Internationalisation
Accessibility and internationalisation are crucial factors to consider when building web applications that cater to a diverse audience. AureliaJS offers built-in support for internationalisation and localisation through the i18n plugin, which simplifies the process of creating multilingual applications. The framework’s commitment to web standards also ensures that it adheres to accessibility guidelines, such as ARIA, making it easier for developers to build accessible applications.
AngularJS provides support for internationalisation and localisation through the AngularJS i18n module. Due to the framework’s reliance on custom components (which don’t always adhere to accessibility best practices), implementing accessibility features in AngularJS can be challenging.
Testing and Debugging
Both AureliaJS and AngularJS offer testing and debugging capabilities to help developers build reliable and maintainable applications. AureliaJS supports a variety of testing tools and libraries, including Jest, Karma and Protractor. The framework’s modular architecture and dependency injection system make it easy to write unit and integration tests for individual components and services.
AngularJS also supports various testing tools and libraries such as Jasmine, Karma and Protractor. The framework’s extensive documentation and community resources can assist developers in setting up testing environments and writing test cases. However, AngularJS’s complexity and reliance on custom directives can make testing and debugging more challenging compared to AureliaJS.
Scalability and Enterprise-readiness
AureliaJS stands out due to its modular architecture, performance optimisations and adherence to web standards, which makes it easy for developers to build, maintain and scale applications as their requirements grow. AureliaJS’ flexible and scalable nature enables organisations to develop custom solutions based on their specific needs while maintaining a future-proof codebase.
AngularJS, while widely used in enterprise applications, can face scalability challenges due to its two-way data-binding mechanism and reliance on custom directives. When combined, these factors can trigger performance issues in large-scale applications, reducing the ability of organisations to maintain — let alone maintain — their AngularJS projects over time.
Mobile and Progressive Web App Support
AureliaJS offers support for building mobile and progressive web apps (PWAs) through its integration with popular tools such as Cordova and the Aurelia CLI. These integrations enable developers to create responsive, native-like experiences with offline capabilities, ensuring that their applications can be accessed on various devices and platforms.
AngularJS also provides support for building mobile and PWAs through its integration with tools like Ionic and Cordova. Due to the framework’s age and performance limitations, developers are likely to encounter challenges when looking to create applications with a focus on high performance and responsiveness — two qualities most consumers expect from applications these days.
Now that we’ve explored some of the key differences between these two popular frameworks, it’s time for us to dive deeper into the five key benefits of choosing Aurelia vs Angular.
AngularJS’s routing systems can be incredibly difficult to work with and extend, especially in complex applications. This frontend development framework relies on a more rigid routing configuration, which can limit developers’ ability to create advanced routing scenarios.
When you compare this with the fact that AureliaJS provides a powerful and flexible routing system that is easy to configure and extend, it’s evident why the latter is superior. AureliaJS supports nested routing and allows developers to define routes with simple, readable syntax. This approach enables the creation of complex applications with ease and a more maintainable codebase.
2. Standards Compliance
AngularJS often relies on custom attributes and elements, which may not align with current and future web standards.
On the flip side, AureliaJS was designed to adhere to web standards, ensuring that applications built using this framework are compatible with modern browsers and comply with best practices. By choosing AureliaJS, developers can ensure their applications stay up-to-date with evolving web standards and maintain better long-term compatibility.
3. Many Languages Supported
AureliaJS’s language support enables a broader range of developers to work with the framework comfortably.
4. Scalable HTML
AureliaJS enables developers to create custom elements and attributes, allowing for greater flexibility and reusability of code. This scalability simplifies the process of building complex user interfaces and promotes a more maintainable codebase.
In comparison, AngularJS relies on custom directives, which can be inconvenient at best and cumbersome at worst. Plus, they are not as easy to repurpose. AureliaJS’s approach to extensible HTML aligns with web standards and encourages the creation of more modular and scalable applications.
5. Data binding
While both AureliaJS and AngularJS offer data-binding capabilities, AureliaJS provides a more efficient and performance implementation. Its one-way data-binding approach helps minimise potential performance issues in large-scale applications while still offering a simple and intuitive way to manage data.
AngularJS, on the other hand, utilises two-way data binding, which can sometimes lead to performance problems in complex applications. By adopting AureliaJS’s one-way data-binding, developers can ensure better application performance and a smoother user experience.
Migrating from AngularJS to AureliaJS can be a complex process due to the two frameworks’ differing architectural approaches and design philosophies. However, the benefits of adopting AureliaJS, such as improved performance, maintainability and standards compliance, can make the migration worthwhile for some projects. Luckily, the AureliaJS team has provided resources and guidance on transitioning from AngularJS to AureliaJS.
