JHipster Conf 2018: Summer Solstice in Paris

Last week, I journeyed to Paris with my son, Jack. It was his first time in Europe and I brought him along for good reason. I’d been invited to the first ever JHipster Conf, and I was eager to attend. We were both pretty excited when we left Denver last Monday.

My Background with JHipster

I’ve been a part of the JHipster community for a few years now. I joined by accident, really. I was trying to market myself as an independent consultant by spouting my knowledge of Spring Boot and Angular with an InfoQ mini-book. Since JHipster leveraged both to jumpstart app development, it seemed like a perfect fit. I’ve been a long-time fan of app jumpstarts, having developed my own called AppFuse in days long gone.

Through the process of writing the mini-book, finding issues, and submitting pull requests, I eventually found myself to be a member of the JHipster development team. Through my relationship with JHipster, and it’s 3.0 release, I found myself intrigued my microservices and how to develop them with Spring Boot, Spring Cloud, all through the generation expertise of JHipster.

I’ve learned a ton by being part of the project and trying to figure out how all of its options work.

When I found myself with a full-time job at Stormpath, I did my best to create a Stormpath module for JHipster. When Okta acquired Stormpath, I added a similar module to my list of things I wanted to write.

When it came time to implement an Okta module, I discovered JHipster’s OAuth support only worked internally, not with an external OAuth provider, also known as an Identity Provider, or IdP. I mentioned to the JHipster team I thought we could do better and add support for external providers instead. They agreed, and I went to work.

In hindsight, it was a great decision and not terribly difficult to implement thanks to Spring Security, Keycloak, and Docker. We had a ton of help from the community along the way, and as of last October, JHipster added support for single sign-on with OIDC (tested with Keycloak and Okta).

JHipster 5.0: Spring Boot 2.0, Angular 6, and React

It’s been a fabulous adventure on the JHipster train and it’s still going strong. We just released version 5.0 with React and Spring Boot 2.0 support, there’s client generators for Ionic and React Native, and we just hosted a kick-ass conference about JHipster in Paris.

JHipster Conf 2018

The conference featured members of the core team, the well-dressed and fit Joe Kutner from Heroku, as well as Java celebrities like Ray Tsang and Josh Long. You can read about the festivities and presentations from JHipster's founder, Julien Dubois.

The conference was a little over 24 hours long, starting with a speaker’s dinner on Wednesday evening. Before attending, Jack and I spent the day strolling around Versailles. Versailles is a special place in my life since I proposed to my double rainbow there after Devoxx Belgium in 2011.

The conference kicked off with a keynote by the JHipster's co-leads: Julien and Deepu.

During my talk, I had Jack join me on stage for an intro, and tried to give him a taste of public speaking in front of hundreds.

My talk went well, with some successful and some failed demos. Hopefully people got the point that it’s cool to store your users outside of JHipster so you can share them between apps. I also tried to show that OAuth and OIDC are excellent for securing APIs. You can download my presentation from Add JHipster to Your JHipster Apps with OIDC or view it below.

I created a tutorial of the app I showed in my talk and published it to the Okta developer blog: Build a Photo Gallery PWA with React, Spring Boot, and JHipster. If you like React and OAuth, you're gonna love this guide!

Jack and I had a day in Paris after the conference, so we made the most of it. We hit the Eiffel Tower, hiked the stairs, and marveled at the view. After, we waited in a long line for The Catacombs and walked among the dead.

Kudos to the JHipster Community!

What a trip! It’s so much fun to be a part of JHipster’s thriving open source community. It’s not just the project itself; it’s all the projects we build upon, from Java to TypeScript to Spring Boot to Spring Data to Spring Security to Angular to React to webpack to Bootstrap. It’s a conglomeration of all of my favorite tools and open source developers encompassed in several awesome projects!

Life as an open source developer is pretty fun. I encourage you to get involved in open source too! I started way back in the early 2000s with Struts and Ant, and it’s done wonders for my career.

Viva La Open Source!

SpringOne, The Rich Web Experience, and Being Home for the Holidays

A few weeks ago, I had the pleasure of hitting two excellent conferences in one week: SpringOne and The Rich Web Experience. The primary reason I like both conferences so much is that there are so many familiar faces.

I had a gas hanging out with folks from Pivotal after I arrived on Monday night. On Tuesday, I thoroughly enjoyed the opening keynote. Seeing the unveiling of Spring Boot 2.0's most impressive feature was spectacular too!

I walked to the Okta office for some swag that afternoon, then proceeded to the Atomist happy hour. I talked with Rod Johnson about how Atomist might be able to help update our example apps and the Okta Developer blog. Since keeping our posts and examples up-to-date is a maintenance burden, I think Atomist could be a huge help.

After happy hour, a bunch of us joined Heroku for a delicious dinner and fun conversations.

On Wednesday, I delivered my talk on Bootiful Development with Spring Boot and React. You can find my slides on Speaker Deck.

It was recorded and published to YouTube as well.

After my talk ended, I only had 70 minutes before my flight took off for Florida and the Rich Web Experience. Luckily, there was hardly any traffic and I found myself boarding with 23 minutes to spare.

A Stressful, but Rewarding, Trip to Devoxx Belgium and Morocco

One of my favorite conferences in the world is Devoxx Belgium. First of all, it tends to have one of the most enthusiastic audiences I've ever seen. Secondly, its organizers are super awesome and challenge you to give great talks. Third, it was the first conference I ever took my Trish to. In 2011, I took her a second time and proposed to her in Paris afterward.

This year, I traveled to Devoxx Belgium for the first time without Trish. It was stressful because I didn't prepare well beforehand. However, it was also gratifying because I was able to make everything work, even it all happened at the last minute. Furthermore, I did the majority of my talks with good friends, which is always a pleasant experience.

The purpose of this blog post is to document my experience this year, so I can look back and say WTF was I thinking?!

I left Denver on Monday (November 6) afternoon and flew to Brussels, Belgium. My flight landed in Brussels at 9 am and Josh and my (three hour) talk was at 1:30 pm. I made it in time, but it was one of the first times we didn’t have a lot of time to prepare face-to-face beforehand. I learned that getting t-shirts printed in the US to save $500 is a good idea, but having to take two suitcases to carry them all is a bad idea.

We did our usual talk and I used Okta's new Angular SDK instead of the Sign-In Widget to showcase authentication. Even though the crucial step I needed was contained in my notes, I failed. One simple line to add an HttpInterceptor and I missed it!

I think I followed up well with a tweet that showed how to fix it. But who knows how many people use Twitter. One things for sure, people tweet more at Devoxx Belgium than any other conference I’ve ever been too! In fact, the #Devoxx hashtag got hijacked by some porn sites and their tweets started showing up on the Twitter wall. 

I tweeted about what I forgot to do after our talk.

Josh and my talk was published on YouTube the very next day, which is awesome.

Devoxx Poland: A Huge Conference in a Beautiful City

It's been a little over six years since I first ventured to Kraków, Poland. I have fond memories of that trip, mostly because Trish was with me and we explored lots of sites. Last month, I visited Kraków for GeeCON, but only stayed for one night.

Last week, I had the pleasure of visiting a third time for my first Devoxx Poland. I was excited to travel internationally again with my favorite travel shirt on. This caused a funny conversation with TSA just before my departure.

I arrived in Krakow on a beautiful day and took an Ubër to my hotel next to the venue. I took a stroll along the Vistula River to enjoy the sunshine.

Speaking Adventures at J-Spring, Devoxx UK, GeeCON, and Spring I/O

As a Developer Advocate at Okta, I'm expected to travel up to 25% per month to speak at conferences and meetups. This May was more like 50%! I had opportunities to contribute to a number of cool conferences in exotic cities that I was eager to accept.

My adventure began on Monday, May 8 when I flew to Amsterdam to speak at the J-Spring conference. It was the first time the NLJUG hosted this conference in several years. I marveled at the venue and especially liked the outdoor area it offered during breaks. The walk from/to the train station was pretty nice too.

I spoke about Microservices for the Masses with Spring Boot, JHipster, and JWT. Feedback I received mentioned it was a bit too fast and I crammed too much into the 50-minute time slot. I do tend to mention everything I know about topics when I speak, so I apologize for trying to cram too much in.

Angular and Cloud Native PWAs at Devoxx France

Devoxx France is one of my favorite conferences. As you might know from my post about Jfokus, I thrive on a sense of community and the memories created by conferences. Last week in Paris, I experienced a passionate community and created several memories, with many good people and friends.

I had two speaking events at the conference:

• The Ultimate Getting Started with Angular Workshop
• Building Cloud Native PWAs with Spring Boot, Spring Cloud, and Angular - Part Deux

For the workshop, I intro'd Angular, had the class create an Angular application, then talked about testing Angular. In additional, I showed them a number of demos:

• Integrate Angular Material
• Integrate Bootstrap 4
• Deploy to Cloud Foundry
• Deploy to Heroku
• Continuous Integration with Jenkins
• Authentication with OpenID Connect and Okta

Update: Videos of Josh and my Cloud Native PWAs talks have been published to YouTube. Hope you enjoy!

Let the Okta and Devoxx Journeys Begin!

It's been almost a month since Stormpath joined forces with Okta. My first day at Okta was on February 27, and I was only briefly in the San Francisco headquarters. I had to fly out at noon on my second day, so I hunkered down in the Okta Pub and cranked out a presentation for a talk with Micah Silverman at the Kansas City Spring User Group.

That's right, Okta has a pub in their SF HQ. When I first heard about this, I knew it'd be a good fit for me!

Now properly fortified, I finished the presentation and headed for the airport, where I rejoiced in my clothing choices for the day.

The whirlwind of ramping up at Okta hasn't died down yet. Last week, I figured out how to authenticate with Okta's API using Spring Boot and SAML. I also got an OAuth 2.0 example working. Then I moved onto Angular and got an example working with OpenID Connect (OIDC), Okta's Sign-In Widget, and the Okta Auth SDK. I was especially pumped when I got an Angular client working with OIDC and a Spring Boot + Spring Security backend. This week, I wrote up my findings as tutorials and recorded a couple screencasts to accompany them. These will likely show up as blogs posts on Okta Developer Blog over the next few weeks.

While the first couple of weeks at Okta has been exciting, I'm more excited about the upcoming Devoxx conferences I'll be speaking at.

Next week, Devoxx US will be happening for the first time! As a member of the program committee, I promise you this is going to be a great show! We had an incredible number of high quality submissions and it shows in the agenda. I'm especially looking forward to Janelle Klein's What is Identity? keynote. I'll be doing talks on JHipster, Asciidoctor, and how NOT to restore a VW Bus.

Speaking of the bus, Hefe sure looks good, doesn't he?

After returning from Devoxx US, Trish and I are taking Abbie and Jack on the spring break trip of a lifetime. I've never been to Big Sky, so we're heading there for a week of skiing, frolicking, and playing in the snow. I might even go phoneless for the week to fully embrace the serenity that Montana provides.

I'm off to Devoxx France the following week. I'm really looking forward to this conference because my talks are all about Angular. I'll be doing a hands-on lab on getting started with Angular, as well as developing a PWA with Josh Long.

To make things even better while I'm on the road, I'm getting some work done on both VWs. We're getting Stout the Syncro painted and having a stereo installed in Hefe. With any luck, Stout 5.0 and Hefe 3.0 will be released in April, just in time for the car show season.

So yeah, life is pretty darn good right now. Let me know if you'll be in Tahoe, San Jose, Big Sky, or Paris when I'm there. I'd love to chat about authentication, open source technologies, VWs, or good beer.

A Jolly Good Time at Jfokus 2017

I like speaking at conferences. I don't enjoy the stress of creating a new talk and delivering it for the first time, but I do enjoy delivering talks, and I love the feeling after. It's even better when the conference provides an atmosphere that creates lasting memories.

I've been to many conferences in my career. A conference with a sense of community provides one of my favorite experiences. Not just for the people that attend, but for the people that speak. I've been to several conferences that provide this experience and I'm happy to say I just attended one of my favorites: Jfokus 2017.

I flew from Denver to Stockholm last Monday and performed my first talk on Testing Angular Applications just a few hours after I arrived on Tuesday. Usually, I take a day or two to recover from jet lag, but this time I figured I could clutch up and make it work. Going to sleep on the plane at 6pm Denver time certainly helped and I think the talk went well. For the live coding part of the presentation, I used the second half of my Angular and Angular CLI tutorial. I posted my slides for this talk to SlideShare and Speaker Deck. You can also view them below.

Tuesday night, there was a conference party. I met many new people and put some names to faces with a vibrant community of conference attendees and speakers.

Upcoming Events: Devoxx4Kids Denver, Testing Angular 2, DevoxxUS CFP and VJUG24

It's been awhile since I've posted anything on this here blog. That usually means one thing - I've been off having fun! That couldn't be more true this summer. The day after my last post, I began traveling and haven't stopped since. In fact, this weekend will be the first weekend I've been home since writing that post. Hawaii, Montana, Denver, Montana, Colorado Springs and Utah - it's been a fabulous summer. I'll write more about those adventures soon.

In the meantime, I wanted to mention some upcoming events you might be interested in:

• September 10: Devoxx4Kids Denver has an upcoming workshop on Exploring JavaScript with the world famous Dr. Venkat Subramaniam. If you know Venkat, you know this is a session you shouldn't miss. Your kids will love it, you'll get a lot of good laughs and everyone is sure to have a good time. Make sure and RSVP soon so you get in before this baby fills up!
• August 22: HTML5 Denver has a sessions on ES6 vs. Typescript and Testing Angular 2 Applications. The first session will be delivered by my good friend Geoffrey Filippi and I'll be performing the second act with the help of angular-cli.
• September 1: One of my favorite conferences, Devoxx, is coming to the US! DevoxxUS recently announced that registration is open. Even more interesting is that the CFP begins September 1st. I'm biased because I'm on the program committee, but I'd love to see your ideas for great talks!
• September 27: Our good friends from vJUG are hosting the first 24 hour Virtual Java Conference in the world! I'll be speaking about the Art of Angular in 2016 at 10pm EDT.
• September: I'm looking for new clients. My current contracts end on August 31 and I'm searching for the next cool team to work with. My expertise: Java, JavaScript and I'm really good at CSS. This is a hard combination to find! LMK if you have a need.

I hope to see you at one of these events!
