Why enterprises welcome Angular

This year I already ran about ten Angular workshops and made several presentations at various conferences (e.g. DevoxxUS, DevNexus, BuzzJS, JEEConf). Over the last 20 years, I’ve been running workshops on different software but I don’t recall seeing such a positive reception of any new software as I see with the latest Angular framework in the enterprise world.

I was thinking of why enterprise developers like it so much, and here what I came up with:

– Getting started with a new project is a breeze thanks to Angular CLI code generator

– TypeScript is an optionally-typed object-oriented language with many constructs that Java and C# developers already know (classes, inheritance, interfaces, generics, annotations)

– A typical enterprise Java developer hates JavaScript, but from what I’ve seen so far, they like TypeScript. No wonder that a recent survey on StackOverflow lists TypeScript as a third most loved language.

– Even though you write code in TypeScript, you can still use thousands of existing JS libraries in your app. With 3K+ type definition files your IDE will offer auto-complete and will show compile-time errors if you try to use the API of these libraries incorrectly

– Most popular IDEs offer great support for TypeScript

– Angular offers a clean separation of the UI (templates) and business logic (TypeScript)

– Angular is not an MVC, but a component-based framework with a clean way of arranging loosely-coupled communication with components

– The Angular rendering engine allows to replace HTML with a third-party markup, and there are already products that offer another markup for developing the UI for mobile apps.

– Angular supports modularization and lazy loading, which allows to substantially decrease the size of the landing page of the app (think perceived performance and module re-usability)

– The size of the landing page of literally any app can be as low as two-tree hundred kilobytes (not counting the app images and third-party JavaScript libraries).

– Angular Universal supports server-side rendering

– There is already a large community of Angular developers, and the questions on StackOverflow are answered pretty fast

– Bundling and optimizing the app code for deployment is simple and doesn’t require you to write complex scripts and manually configure the tools

– From a project manager’s perspective, adopting Angular is a safe bet. If you need to replace or bring a new Angular developer to the team, he/she already knows the set of all required modules and how they operate. This would not be the case with other libraries or frameworks (e.g. React) that would require someone to pick multiple building blocks from third-party vendors, which may be different for each enterprise app.

This is all good, but what has to be done to increase the adoption of Angular in the enterprises?

– The Angular team should substantially increase the speed of developing new UI components in the Angular Material 2 library. They release hight quality components, but there are only 26 of them at the time of this writing, which is not enough for the enterprise apps. Currently, we have to use third-party UI libraries in addition to Angular Material to fill the gaps.

– I’d change the priorities in Angular Material 2 component developments. The lack of a data table component (similar to angular-ui-grid for AngularJS) is a serious obstacle in adopting Angular. I realize that the data table is probably the most complex UI component, but it’s crucial for the most enterprise apps. You can find data table components elsewhere, but in the ideal platform, all batteries are included.

– Implement the responsive layout in Angular Material 2. Currently, you can use either Bootstrap or the flex-layout library, but again, it would be nice to have everything as a part of the Angular package.

Finally, I’d like to mention some specific use cases. Currently, I’m working on a project to migrate a large codebase written in Adobe Flex framework. Moving the code from Flex to Angular is smooth. Within the next couple of weeks, I’ll blog providing more details.

I’d also like to bring the attention of Java developers to a very interesting project called JHipster. It’s a code generator that allows you to generate a complete Angular/Spring Boot app with configured controllers, services, and entities. With JHipster you can either generate a monolith or microservices app with generated config files for deployment on popular cloud platforms.

If you’re not familiar with Angular yet, listen to my conversation with the folks at Software Engineering Radio podcast where I answered multiple questions about Angular. If you’re a Java developer, watch my presentation at DevoxxUS conference.

While typically I run private Angular workshops by requests, in about a month I’ll be running a public online workshop with my colleague and the co-author of our Angular book.

DevOps is under attack because developers don’t want to mess with infrastructure. They will happily own their code into production, but want to use platforms instead of raw automation. That’s changing the landscape that we understand as DevOps with both architecture concepts (CloudNative) and process redefinition (SRE). Rob Hirschfeld’s recent work in Kubernetes operations has led to the conclusion that containers and related platforms have changed the way we should be thinking about DevOps and...

Companies are harnessing data in ways we once associated with science fiction. Analysts have access to a plethora of visualization and reporting tools, but considering the vast amount of data businesses collect and limitations of CPUs, end users are forced to design their structures and systems with limitations.

Enterprises are adopting Kubernetes to accelerate the development and the delivery of cloud-native applications.
