The Angular Mini-Book The Angular Mini-Book is a guide to getting started with Angular. You'll learn how to develop a bare-bones application, test it, and deploy it. Then you'll move on to adding Bootstrap, Angular Material, continuous integration, and authentication.

Spring Boot is a popular framework for building REST APIs. You'll learn how to integrate Angular with Spring Boot and use security best practices like HTTPS and a content security policy.

The JHipster Mini-Book The JHipster Mini-Book is a guide to getting started with hip technologies today: Angular, Bootstrap, and Spring Boot. All of these frameworks are wrapped up in an easy-to-use project called JHipster.

This book shows you how to build an app with JHipster, and guides you through the plethora of tools, techniques and options you can use. Furthermore, it explains the UI and API building blocks so you understand the underpinnings of your great application.

Choosing a JVM Web Framework

I plan on rewriting my "Comparing Java Web Frameworks" presentation for this year's Colorado Software Summit. Rather than "Comparing Java Web Frameworks", I'm going to make it into more of a "Choosing a JVM Web Framework" presentation. I think this opens it up to more possibilities such as Grails, JRuby on Rails, Flex and GWT.

One of the things I hope to talk about is choosing the right tool for the job. I think there's 3 types of web applications you can develop:

  1. Consumer-facing, high-traffic, stateless applications
  2. Internal, more desktop-like applications that are stateful
  3. Media-rich applications that require a RIA framework like Flex

Once you've decided on which of these you're developing, it's much easier to narrow down the choices:

  1. Struts 2, Spring MVC, Stripes
  2. JSF, Tapestry, Wicket
  3. GWT, Flex, OpenLaszlo

I'm not sure if GWT fits in the RIA category. I'm not sure where Rails or Grails fit either. They more closely resemble category #1 than any other, yet there's a lot of speculation about their scalability. I think if that perception can be changed, they'll fit into the first category quite well. However, I don't think they compete with component-based or RIA because they don't hold state or offer rich-media capabilities.

Sidenote: I find the scalability debate quite interesting. There's a fair amount of propaganda in Javaland that scalability can be achieved with appservers and clustering tools like Terracotta. If this is true, I've yet to read good solid proof of it. Most of the "how to scale" information out there suggests "share nothing" architectures that shard data and applications across several servers. Of course, there's scalability and then there's massive scalability. Can appservers and clustering solve massive scalability like Google and Amazon require?

The 2nd and 3rd categories have someone of a blurry line, so I'm hoping to figure out how to clarify that. There's also a lot of other factors that will go into choosing a web framework. What if you're simply trying to replace a home-grown framework with an open-source one? If you want to keep your backend and all its logic, does it make sense to use something like Seam, Grails, JRuby on Rails or even AppFuse? Probably not - all their wizbang features and CRUD generation doesn't mean much if all you're using is the web framework. Also, if your application requires support for non-JavaScript browsers (for 508 compliance), then GWT and JSF can be easily eliminated. I know that there are many claims that JSF doesn't require JavaScript, but I've yet to see a real-world application developed with JSF that expects JavaScript to be turned off. Progressive enhancement is a requirement by many of my clients these days.

What's your opinion? How can we make it easier for developers and companies to choose a web framework? Is categorizing application types a good technique?
