Google's open source framework, Angular, includes a rich environment for developing business applications. GrapeCity’s Wijmo, which supports Angular, is known for providing UI components for business applications and provides first-class Angular support. We talked to Google's Rob Wormald and Jules Kremer, who handle promotion activities of Angular globally, along with Masakazu Segawa, product manager of Wijmo about Angular's benefits for developers creating business applications.

Angular: A scalable web application framework
Could you please tell us about Angular's key features?
How does Angular achieve that scalability?
Wormald: There are various aspects to scalability, the first being scalability of development teams. For example, in large-scale teams, different members have different ways of thinking and doing things. In those situations, Angular provides a proper frame, a nice way of doing things, and brings consistency. That way, it can support a team of hundreds or thousands of developers. Actually, even at Google, we're using Angular in large-scale applications. Another aspect of scalability is the scale of the application itself. Generally, in big applications, there's a tendency to experience a delay in startup or operations as it loads the entire web application at once. In the case of Angular, it supports lazy loading, and so it loads the required thing at the required moment. In other words, even if your application is large-scale, you don't need to worry about loading it all at the time of startup and making it heavy. Then there's a performance aspect. Angular has a change detection feature. This technology quickly rewritea the changed area only when there's a change in the web browser screen. Thanks to change detection, we're five times faster compared to version 1 of Angular. In the Angular environment, you can actually focus on the business logic instead of thinking about minute things like optimization of loading process. At Google, we focus a lot on data. While developing Angular, we always verify the execution speed and take a benchmark for every added feature so that there's no delay. So, during the development process, if we had to make a choice between feature and performance, we choose performance.
What are the merits of Angular for developer of a business application?
Angular is a leader in Web components as well, isn’t it?
Wormald: Encapsulation is really important in the development of large-scale applications. Angular supports web components, which is one of the technologies that achieves that. And not just the web components; Angular components and Polymer components also handle it the same way. Those work just by adding in an Angular application. Web component technology is already mature and available.
Angular and Third-Party UI Component Vendors
Angular has components for business use, just like Wijmo. How do you see your relationship with such vendors?
Jules: Wijmo's development team and Google’s Angular team are working in close communication with each other--so closely that Wijmo’s Angular 2 supported version and our Angular 2 were released almost at the same time. This kind of relationship is good for Google and the vendor, and it also benefits the web application developers.
Mr. Segawa (GrapeCity), being a component vendor, how do you rate the Angular framework?
Segawa: I think it's really convenient for component vendors to use because Angular components are based on the standard specifications of ECMAScript. We can easily support Angular components in Wijmo with minimal code and few alterations in actual Wijmo code. We just had to inherit the Wijmo component classes and define the properties and events. As a result, we could adopt Angular with minimal effort, and also with minimal performance overhead. As a component vendor, I think Angular is an excellent framework that's also easy to deploy.

Merits of combining Angular and UI components
How can developers benefit by from Wijmo's Angular support?
Segawa: There are so many UI libraries and components available, not only for Angular, but some based on JQuery, and some independent libraries. One has to research and learn each, as their usage and implementation are quite different. Since Wijmo supports Angular, the developers who know Angular components can easily use Wijmo, as well. It's all directly related to developers' learning curve. I believe the development productivity increases by combining Wijmo’s feature-rich components with the Angular framework. In addition, I think Angular will be increasingly used in the enterprises, and as that adoption increases, I think Wijmo will be a more common choice for enterprises, which is definitely a big thing for us.
Achieve zero re-writing of code by developers
What are your plans with Angular?
Jules: Improving performance is definitely one thing. Along with that, we'll focus on enhancement of the tools meant for enterprise developers. Wormald: Going forward, Angular will continue to evolve with the web, but we won't change the Angular API. We want to ensure that developers won't have to re-write application code in future. It's important that Angular maintains both stability and flexibility. Lastly, we'll get feedback from component vendors who support a wide range of use cases and share that feedback with the development team so we can create a roadmap accordingly. Segawa: There were issues while we were adding support of AOT compiler in Wijmo. At that time, we solved it with the help of Rob and Angular's development team. We'd like to continue this kind of collaboration in future, as well. Wormald: So would we. Segawa: Wijmo has a lot of know-how of various components that have been developed across different platforms over time, and we've also integrated learning from customer feedback. We'll continue to provide productive feedback to the Angular development team so that, together, we can make Angular even better.
