While the second edition of Angular is still in its infancy, it’s already proving to be leaps ahead of its predecessor. In looking at how Angular 2 is positioned to shape the future of Web development, we examine what is working so far, what elements of the framework are still lacking, how it measures up to other frameworks and its outlook and implications for developers.
Compared to Angular 1, most would agree that Angular 2 is a vast improvement, with its revamped core architecture, TypeScript for development, observer pattern and data binding model. Additionally, it provides up to 10-times faster performance and better concepts for UI components, giving developers the ability to make excellent applications in their preferred environment.
What Needs Work
While it is proving to be a far superior framework than version one, Angular 2 comes with some limitations and drawbacks as it retires from beta.
When the first details around Angular 2 were announced at ngEurope, the initial reaction from many developers was negative. This sentiment arose largely from Angular 2’s lack of backwards compatibility and the elimination of Angular 1’s APIs. The second Angular framework did drop several APIs from the first version, and since it is not backward compatible most developers had to rewrite portions of applications to make the upgrade.
Angular 2’s most glaring issue today is that the framework is lacking some UI components and integrated tooling. Developers are still working out the best way to use the Angular command-line interface (CLI), which has not yet had a 1.0 release. Furthermore, many developers not comfortable using the CLI are still waiting for Angular to be integrated into their IDE of choice, like Visual Studio. While Angular provides some tooling, it is going to take time for third-parties to step in to provide all these necessary enhancements. Angular 2’s release should help spur that, serving to alleviate vendors’ hesitancy to add support to the still-evolving framework.
Compared to other top frameworks, like Ember and React, Angular 2 is often preferred by developers today. Ember is similar to the Angular 2 framework because it is also fully featured. However, Ember doesn’t give developers a way to run code on multiple platforms. React does allow this, with React Native, and Angular does with NativeScript. This restricts Ember developers from sharing their code across multiple development environments.
React is a more minimal framework, and React developers need to use a number of different community-written tools to ship an application. Developers are in favor of using Angular 2 because these dependencies are maintained in the core project, which gives them a framework that can be reliably maintained throughout the project’s life.
Angular 2’s Outlook
While Angular 1’s primary purpose was to provide a framework for building Web apps, Angular 2 will allow developers to further expand their endeavors and build on top of them. The release of Angular 2 brought a faster, more powerful and more consistent framework to developers around the world, and freed developers to build apps not only inside the browser but in other ecosystems.
Young as it is, Angular 2 was made to be tool-able, which will help to streamline and improve Web application development. Web developers must assemble an intimidating set of libraries and frameworks to ship a modern application – Angular 2 has a framework that provides much of the functionality out of the box. As more vendors provide support for it, the Angular 2 framework will become better still.
For now, Angular 2 works best in non-trivial applications (those have 10 or more views) and those that utilize a significant amount of data. Yes, Angular may be used to build nearly anything – but the framework’s inherent complexity is overkill for the simpler apps that need a single platform to run. While other frameworks might see increased adoption among smaller companies and startups, we’ll probably see massive growth among enterprise adoption of Angular 2. Angular 1 is already popular at these large companies, and their developers are ready for an upgrade.
