I had the pleasure to do 2 presentations at NCUG, formerly known as ISBG. It were very technical questions, but was happy that people where brave enough to attend šŸ˜‰

Spring forward: an introduction to Spring boot and Thymeleaf for (XPages) developers

The world of (XPages) developer is moving fast. Customers rethinking platforms and solutions. Spring Bootmakes it easy to create stand-alone, production-grade Spring based Applications that you can “just run”. In combination with Thymeleaf can it be good alternative for your XPages applications.

In this session I give an introduction of Spring Boot and Thymeleaf and how to get started. I will show the differences and similarities between Spring Boot in combination with Thymeleaf and XPages.

I will explain the challenges I faced when moving an application.

Super charge your APIā€™s with Reactive streams

Today almost every product has an API, to integrate in other products or to  made the data available to the outside world. Most APIā€™s are using traditional patterns and technology. With the rise of Angular, React and other modern frameworks there is a need for non blocking APIā€™s. Meet Reactive streams, like Spring Webflux, to super charge your API.

In this session I will tell about and show you Reactive APIā€™s and more

[slideshare id=149305075&doc=isbg2019reactivestreams-190612140649]

I created a demo application application with a Angular frontend, it can be found here: https://github.com/flinden68/reactive-streams-starter

Hope it will help you to get started in the Spring Boot / Webflux world. If you needs help, let me know

Engage 2019: The good, the bad and the ugly: a not so objective view on front end development

16-05-2019 no responses flinden68 community development

This week was Engage 2019 in Autoworld in Brussels.

Theo Heselmans and crew did an amazing job, again, in a stunning venue. I was privileged to be speaking again.

My Session

I was really surprised to have a full room. I enjoyed it very much to deliver my opinion on the current most populair front end frameworks, VueJS, React and Angular.

[slideshare id=145974196&doc=engage2019thegoodthebadtheugly-190516061444]

Demo application

For this session I created a demo application to show how you can use React, Vue or Angular to build the exact same application. As API layer I created a Spring Boot and NodeJS version. Inside the repository is also a Python version, but be aware that there is the Account CRUD operations are missing.

The repository can be found here, https://github.com/flinden68/my-events-demo-application.

Feel free to fork, clone or enhance the repository. Keep in mind it was my way to build the front ends, there are more ways to reach a goal.

21-12-2018 no responses flinden68 business community development
2018

2018 is almost over, a reason to share some thoughts.

  • I was a double IBM Champion, Collaboration and Cloud.
  • Attended IBM Think in Las Vegas.
  • When in Las Vegas I did the St. Patrick run near the Hoover Dam.
  • Delivered a portal for a big city in the Netherlands, based on Spring Boot and Thymeleaf
  • Still at Rabobank, doing interesting projects
  • My oldest daughter moved to another volleyball club to get more out of her sport
  • We did a road trip though the Rocky Mountains in the USA
  • … and visited New York, where Bill Malchisky spent time with us as a tour guide. Many thanks….
  • Spoke at several events like EntwicklerCamp, SNoUG, Engage, IconUK and Social Connections
  • Presentations were about Spring Boot and Reactive API.
  • Hope to keep sharing my knowledge in 2019
  • Learnt a lot about Spring Boot and Pivotal Cloud Foundry
  • Learnt CosmosDb on Azure as MongoDb and hate it right away šŸ˜‰
  • Still a fan of MongoDb and explored the new cloud offering MongoDb Atlas.
  • Build applications with Angular and React
  • Build the same API with Spring Boot, NodeJS and Python to learn more. In my pet project NodeJS was the winner.
  • Did some beta testing with Domino v10 beta2
  • Was not surprised HCL will take over the whole IBM Collaboration suite.
  • Hope HCL can keep the existing customers on the platform
  • I will not wait and will move on.
  • Already 4 years going strong Freelance Full Stack Developer.
  • My lovely niece, only 5 years old, passed away after she lost the fight of her disease.
  • Remembered our lovely niece on her birthday by wearing 2 different socks.
  • Enjoyed to being part of an amazing ‘yellow’ community. A bit more from the side line…but still part.
  • Running was on a low, but compensated by more on the MTB.
  • Moved my mail and documents from Google to Microsoft Office 365 and I am happy.

Happy 2019

Today I did my session, about Reactive streams at Social Connections 14 in the very sunny Berlin.

Slides of the session

Reactive Streams Starter

For this session I created a starter project, which will give you a kick start if you want to try it your self.

In the ReadMe is more information about the things you need, like MongoDb locally or remote.

BTW in the repository is also a frontend project, build with Angular, which interacts with the API.

The Repository is on Bitbucket

Quick tip: Swagger support for Spring Webflux

14-09-2018 one response flinden68 development Springboot

At my customers when I create microservices I always add Swagger support, because it easy to test the microservice.

Another create benefit it gives the business also a nice UI to see what to expect.

Problem

Now I am preparing a demo for my session about Reactive Programming, which I will give at Social Connections 14 event next month in Berlin, I was thinking how to add support to my Spring Webflux demo.

But the current Swagger versions doesn’t support Spring Webflux

Solution

After some research I found that Swagger2 will add support for Spring Webflux in version 3.0.0

But there is already a SNAPSHOT in the wild with support.

Add version 3.0.0-SNAPSHOT to your dependencies in your pom.xm

After the dependencies are loaded in your project

Go to or create a SwaggerConfiguration class and addĀ @EnableSwagger2WebFlux to your class

 

When you start your application head over to the swagger-ui.html and voila.

 

Happy coding
