Angular Summit 2015

I was in Boston this week, speaking and attending the very first Angular Summit. I had the privilege of delivering the opening keynote on Monday. I spoke about the Art of Angular and used a slide deck similar to last time. I did update the presentation to show the astronomical growth of AngularJS in terms of candidate skills (on LinkedIn) and job opportunities (on

LinkedIn Skills Growth for JavaScript MVC Frameworks Job Growth for JavaScript MVC Frameworks

I mentioned the recently announced good news for Angular 2:

  • We're enabling mixing of Angular 1 and Angular 2 in the same application.
  • You can mix Angular 1 and Angular 2 components in the same view.
  • Angular 1 and Angular 2 can inject services across frameworks.
  • Data binding works across frameworks.

In related news, Craig Dorms recently posted a state-geo-angular project that shows how you can develop an Angular 1.x application that will be easy to upgrade to Angular 2.x. Thanks Craig!

After my keynote, I attended Pratik Patel's session on High Performance JavaScript Web Apps. Pratik pointed out for testing an app's performance and seeing its blocking resources. He also mentioned (currently unavailable) for capturing performance numbers as part of a continuous integration process. Finally, he recommended Addy Somani's JavaScript Memory Management Masterclass.

My second presentation was about JHipster. Near the end of the presentation, I mentioned that I hope to finish the JHipster Book this month. Writing presentations for SpringOne 2GX and the Angular Summit occupied a lot of my free time in September. Now that it's October, I'll be dedicating my free time to finishing the book. In fact, I think I can finish the rough draft this week!

For the last session of the day, I attended John Lindquist's session on Angular 2 Components. John showed us how everything is a component in Angular 2. He also said "now is the time to learn ES6" and built an Angular 2 ToDo App using ES6 and a bit of TypeScript. You might recognize John's name; he's the founder of, an excellent site for learning Angular with bite-sized videos.

Tuesday morning started with a Angular 2.0 keynote from Peter Pavlovich. I really enjoyed this session and received lots of good tips about getting ready for Angular 2. The tweet below from Ksenia Dmitrieva shows his advice.

My biggest takeaway was to start following John Papa's Angular Style Guide ASAP.

The first session I attended on Tuesday was Judd Flamm's Google Material Design & Angular. I'm using Material Design for Bootstrap on a side project, so I was interested in learning more about its inspiration. We learned that Google Design has everything you need to know about why Material Design exists. We also learned about Angular Material and spent most of the session looking at its components. Judd recommended Angular Material-Start for those looking to get started quickly with both frameworks. Judd was a very entertaining speaker; I highly recommend you attend one of his talks if you get the opportunity.

After being dazzled by Peter's knowledge of Angular 2 in Tuesday's keynote, I attended two more of his talks: one on Meteor and another on Aurelia. I've known about Meteor for a while, but have become more intrigued by it lately with its 1.2 release and Angular support. Meteor's command line tools that auto-inject CSS and JS demoed very well, as did it's installable features like a LESS support and Facebook authentication.

After hearing all the good things about Angular 2 from Peter, it was interesting to hear him downplay it in his Aurelia talk later that day. When he started showing code, it was pretty obvious that Aurelia is doing a great job of simplifying JavaScript MVC syntax for developers. You can develop components with almost half the code that Angular 2 requires, and it uses ES6, jspm and SystemJS. If you're developing JavaScript, learning these tools will help prepare you for the future. It's cool that Aurelia encourages learning things you should learn anyway.

Aurelia and Angular 2 are both still in Alpha, so I'm not sure it makes sense to use them on a project this year. However, I do think it's important to track them both. I especially think it's interesting that the founder of Aurelia, Rob Eisenberg, left the Angular Team in November 2014 and announced Aurelia in January 2015 (Hacker News thread). Peter mentioned several times that Aurelia wants to help developers write apps, while AngularJS is more tied to helping Google write apps.

There were around 400 people at Angular Summit, which I think is pretty good for a first-run conference. As with most No Fluff Just Stuff shows, it ran smoothly, had plenty of time between sessions and was filled with knowledgeable, entertaining speakers. It was fun doing my first keynote and I look forward to speaking again in November (at Devoxx) and December (at The Rich Web Experience).

1. I know is probably not a great site, but it makes sense to use it since I've been tracking JavaScript MVC framework job stats on it since February 2014.

UberConf 2015: My Presentations on Apache Camel and Java Webapp Security

Last week I had the pleasure of speaking at UberConf 2015. My first talk was on Developing, Testing and Scaling with Apache Camel. This presentation contained an intro to Apache Camel and a recap of my experience using it at a client last year. You can click through the presentation below, download it from my presentations page, or view it on SlideShare.

My second presentation was about implementing Java Web Application Security with Java EE, Spring Security and Apache Shiro. I updated this presentation to use Java EE 7 and Jersey, as well as Spring Boot. I used Spring Boot to manage dependencies in all three projects, then showed the slick out-of-the-box security Spring Boot has (when you include the Spring Security on the classpath). For Apache Shiro, I configured its filter and required dependencies using Spring's JavaConfig. You can click through my security presentation below, download it from my presentations page, or view it on SlideShare.

One thing that didn't make it into the presentation was the super-helpful pull request from Rob Winch, Spring Security Lead. He showed me how you can use basic and form-based authentication in the same app, as well how to write tests with MockMvc and Spring Security's Testing support.

The next time I do this presentation (at the Rich Web Experience), I'd like to see if it's possible to use all-Java to configure the Java EE 7 example. I used web.xml in this example and the Servlet 3.0 Security Annotations might offer enough to get rid of it.

All the demos I did during the security presentation can be seen in my java-webapp-security-examples project on GitHub. There's branches for where I started (javaee-start, springsecurity-start and apacheshiro-start) as well as "complete" branches for where I finished. The complete examples should also be in-sync with the master branch.

If you have any questions about either presentation, please let me know.

Getting Hip with JHipster at Denver's Java User Group

Last night, I had the pleasure of speaking at Denver's Java User Group Meetup about JHipster. I've been a big fan of JHipster ever since I started using it last fall. I developed a quick prototype for a client and wrote about solving some issues I had with it on OS X. I like the project because it encapsulates the primary open source tools I've been using for the last couple of years: Spring Boot, AngularJS and Bootstrap. I also wrote about its 2.0 release on InfoQ in January.

My Hipster Getup To add some humor to my talk, I showed up as a well-dressed Java Developer. Like a mature gentleman might do, I started the evening with a glass of scotch (Glenlivet 12). Throughout the talk I became more hip and adjusted my attire, and beverage, accordingly. As you might expect, my demos had failures. The initial project creation stalled during Bower's download all JavaScript dependencies. Luckily, I had a backup and was able to proceed. Towards the end, when I tried to deploy to Heroku, I was presented with a lovely message that "Heroku toolbelt updating, please try again later". I guess auto-updating has its downsides.

After finishing the demo, I cracked open a cold PBR to ease my frustration.

I did two live coding sessions during this presentation; standing on the shoulders of giants to do so. I modeled Josh Long's Getting Started with Spring Boot to create a quick introduction to Spring Boot. IntelliJ IDEA 14.1 has a nice way to create Spring Boot projects, so that came in handy. For the JHipster portion, I created a blogging app and used relationships and business logic similar to what Julien Dubois did in his JHipster for Spring Boot Webinar. Watching Josh and Julien's demos will give you a similar experience to what DJUG attendees experienced last night, without the download/deployment failures.

You can click through my presentation below, download it from my presentations page, or view it on SlideShare.

You might notice my announcement on slide #32 that I've signed up to write a book on JHipster.

The JHipster Mini-Book

I haven't started writing the book yet, but I have been talking with InfoQ and other folks about it for several months. I plan to use Asciidoctor and Gradle as my authoring tools. If you have experience writing a book with these tools, I'd love to hear about it. If you've developed an application with JHipster and have some experience in the trenches, I'd love to hear your stories too.

As I told DJUG last night, I plan to be done with the book in a few months. However, if you've been a reader of this blog, you'll know I've been planning to be done with my '66 VW Bus in just a few more months for quite some time, so that phrase has an interesting meaning for me. ;)

Converting an Application to JHipster

I've been intrigued by JHipster ever since I first tried it last September. I'd worked with AngularJS and Spring Boot quite a bit, and I liked the idea that someone had combined them, adding some nifty features along the way. When I spoke about AngularJS earlier this month, I included a few slides on JHipster near the end of the presentation.

This week, I received an email from someone who attended that presentation.

Hey Matt,
We met a few weeks back when you presented at DOSUG. You were talking about JHipster which I had been eyeing for a few months and wanted your quick .02 cents.

I have built a pretty heavy application over the last 6 months that is using mostly the same tech as JHipster.

  • Java
  • Spring
  • JPA
  • AngularJS
  • Compass
  • Grunt

It's ridiculously close for most of the tech stack. So, I was debating rolling it over into a JHipster app to make it a more familiar stack for folks. My concern is that it I will spend months trying to shoehorn it in for not much ROI. Any thoughts on going down this path? What are the biggest issues you've seen in using JHipster? It seems pretty straightforward except for the entity generators. I'm concerned they are totally different than what I am using.

The main difference in what I'm doing compared to JHipster is my almost complete use of groovy instead of old school Java in the app. I would have to be forced into going back to regular java beans... Thoughts?

I replied with the following advice:

JHipster is great for starting a project, but I don't know that it buys you much value after the first few months. I would stick with your current setup and consider JHipster for your next project. I've only prototyped with it, I haven't created any client apps or put anything in production. I have with Spring Boot and AngularJS though, so I like that JHipster combines them for me.

JHipster doesn't generate Scala or Groovy code, but you could still use them in a project as long as you had Maven/Gradle configured properly.

You might try generating a new app with JHipster and examine how they're doing this. At the very least, it can be a good learning tool, even if you're not using it directly.

Java Hipsters: Do you agree with this advice? Have you tried migrating an existing app to JHipster? Are any of you using Scala or Groovy in your JHipster projects?

AppFuse, Reduced

In November, I had some time off between clients. To occupy my time, I exercised my body and brain a bit. I spent a couple hours a day exercising and a few hours a day working on AppFuse. AppFuse isn't used to start projects nearly as much as it once was. This makes sense since there's been a ton of innovation on the JVM and there's lots of get-started-quickly frameworks now. Among my favorites are Spring Boot, JHipster, Grails and Play.

You can see that AppFuse's community activity has decreased quite a bit over the years by looking at its mailing list traffic.

AppFuse Mailing List Traffic, December 2014

Even though there's not a lot of users talking on the mailing list, it still seems to get quite a few downloads from Maven Central.

AppFuse Maven Central Stats, November 2014

I think the biggest value that AppFuse provides now is a learning tool for those who work on it. Also, it's a good place to show other developers how they can evolve with open source frameworks (e.g. Spring, Hibernate, JSF, Tapestry, Struts) over several years. Showing how we migrated to Spring MVC Test, for example, might be useful. The upcoming move to Spring Data instead of our Generic DAO solution might be interesting as well.

Regardless of whether AppFuse is used a lot or not, it should be easy to maintain. Over the several weeks, I made some opinionated changes and achieved some pretty good progress on simplifying things and making the project easier to maintain. The previous structure has a lot of duplicate versions, properties and plugin configurations between different projects. I was able to leverage Maven's inheritance model to make a number of improvements:

Developing Services with Apache Camel - Part III: Integrating Spring 4 and Spring Boot

Spring Boot This article is the third in a series on Apache Camel and how I used it to replace IBM Message Broker for a client. I used Apache Camel for several months this summer to create a number of SOAP services. These services performed various third-party data lookups for our customers. For previous articles, see Part I: The Inspiration and Part II: Creating and Testing Routes.

In late June, I sent an email to my client's engineering team. Its subject: "External Configuration and Microservices". I recommended we integrate Spring Boot into the Apache Camel project I was working on. I told them my main motivation was its external configuration feature. I also pointed out its container-less WAR feature, where Tomcat (or Jetty) is embedded in the WAR and you can start your app with "java -jar appname.war". I mentioned microservices and that Spring Boot would make it easy to split the project into a project-per-service structure if we wanted to go that route. I then asked two simple questions:

  1. Is it OK to integrate Spring Boot?
  2. Should I split the project into microservices?

Both of these suggestions were well received, so I went to work.

Developing Services with Apache Camel - Part II: Creating and Testing Routes

Apache Camel This article is the second in a series on Apache Camel and how I used it to replace IBM Message Broker for a client. The first article, Developing Services with Apache Camel - Part I: The Inspiration, describes why I chose Camel for this project.

To make sure these new services correctly replaced existing services, a 3-step approach was used:

  1. Write an integration test pointing to the old service.
  2. Write the implementation and a unit test to prove it works.
  3. Write an integration test pointing to the new service.

I chose to start by replacing the simplest service first. It was a SOAP Service that talked to a database to retrieve a value based on an input parameter. To learn more about Camel and how it works, I started by looking at the CXF Tomcat Example. I learned that Camel is used to provide routing of requests. Using its CXF component, it can easily produce SOAP web service endpoints. An end point is simply an interface, and Camel takes care of producing the implementation.

Developing Services with Apache Camel - Part I: The Inspiration

In early May, my client asked me to work on a project migrating from IBM Message Broker 6.1 to an open source solution. Their reason was simple, the IBM solution was end of life and outdated. To prove how out of date it was, the Windows version required Windows XP to run. IBM WebSphere Message Broker has been replaced by IBM Integration Bus in recent years, but no upgrade path existed.

At first, I didn't want to do the project. I was hired as a Modern Java/UI Architect and I had enjoyed my first month upgrading libraries, making recommendations and doing a bit of UI performance work. I hadn't done much with ESBs and I enjoy front-end development a lot more than backend. It took me a couple days to realize they were willing to pay me to learn. That's when I decided to clutch up, learn how to do it all, and get the job done. This article is the first in a series on what I learned during this migration project.

My approach for figuring out how everything worked was similar to working on any new application. I get the source code, install the software necessary to run it, and run it locally so I can interact with it.

Why I prefer IntelliJ IDEA over Eclipse

Over the last couple months, I've received a few emails asking why I prefer IntelliJ IDEA over Eclipse. They usually go something like this:

I keep seeing you recommending IntelliJ. I keep trying it intermittently with using Eclipse, but I feel like I'm missing something obvious that makes so many people think it's better. Granted having the usual plugins incorporated is nice, but other things like the build process and debugger sometimes seems a step back from Eclipse. Could you please blog a '10 reasons why I love IntelliJ' or point me to something that would clue me in?

I grew to love IntelliJ for a few reasons. It all started in 2006 when I decided to migrate AppFuse from Ant to Maven. Before that, I was a huge Eclipse fan (2002 - 2006). Before Eclipse, I used HomeSite, an HTML Editor to write all my Java code (1999-2002). Eclipse was the first IDE that didn't hog all my system's memory and was pleasant to work with.

The reason I started using IntelliJ in 2006 was because of it's multi-module Maven support. Eclipse's Maven support was terrible, and m2e hasn't gotten a whole lot better in recent years AFAIK.

Back then, I used to think everything should be built and run from the command line. A couple years later, I realized it was better to run tests and debug from an IDE. Now I'm more concerned with the ability to run tests and debug in an IDE than I am from the build system.

In 2009, I started doing a lot more front-end work: writing HTML, CSS and JavaScript. I also started digging into alternate languages for these: Jade, GWT, CoffeeScript, LESS, SASS - even Scala. I found IntelliJ's support, and plugins, to be outstanding for these languages and really enjoyed how it would tell me I had invalid JavaScript, HTML and CSS.

My original passion in software was HTML and JavaScript and I found that hasn't changed in the last 15 years. AFAIK, Eclipse still has terrible web tools support; it excels at Java (and possibly C++ support). Even today, I write most of my HTML code (for InfoQ and this blog) in IntelliJ.

In reality, it probably doesn't matter which IDE you use, as long as you're productive with it. Once you learn one IDE well, the way others do things will likely seem backwards. I'm so familiar with debugging in IntelliJ, that when I tried to use Eclipse's debugger a few weeks ago, it seemed backwards to me. ;)

In a nutshell: the technologies I've worked with have been better embraced by IntelliJ. Has this happened to you? Have certain technologies caused you to use one IDE over another?
