In the past few weeks I have been working with Elasticsearch. I was missing a plugin to look at the data, create queries and evaluate different facets. That was when I decided to start working on a plugin that enables you to do just this.

I have been working on AngularJS together with Twitter Bootstrap, therefore the choice as to which technology to use was not a difficult one. I also used some additional libraries, but I'll tell you more on this later on.

Why did I put the part 1 in the title? I am going to split this information into two parts. This part deals with the setup of the plugin, the libraries I used and the functionality I implemented. Then the next part deals with providing more details about interacting with Elasticsearch; how I use the facets, create the queries, etc. I will also write down some lessons learned with respect to AngularJS in a later blog post.

Now let's move on and have a look at the features:

Basic Axon Framework sample using vert.x and angular.js

November 27th, 2012 by
(http://blog.trifork.com/2012/11/27/basic-axon-framework-sample-using-vert-x-and-angular-js/)

Some people on the Axon Framework mailing list were asking for more basic samples, preferably using something like vert.x. Since I am familiar with Axon as well as vert.x I thought I could help out. Therefore I have created a very basic application based on vert.x using the Axon Framework. The application is all about maintaining a list of TODO items. These items are shared between all connected web browsers. You have to be able to create a new TODO item and you have to be able to mark them as completed.

During my visit of Devoxx I learned about a front-end framework called AngularJS. This is a very nice addition to the vert.x technology stack. Since I always use Bootstrap for my front-end work, the front-end should look familiar to a lot of you. The following images shows the end result of the application. If you want to know how I created the sample, read on.

Last week a couple of my colleagues and I were in Antwerp visiting the Devoxx conference. In this blog post we try to give you an idea about what we did & learned:

Fronteers Conference 2012 - a retrospect

November 15th, 2012 by
(http://blog.trifork.com/2012/11/15/fronteers-conference-2012-a-retrospect/)

Fronteers Conference 2012 in Amsterdam came and went with a lot of great talks and more importantly, fantastic Q&A. After each talk, Chris Heilmann interviewed the speaker using questions tweeted by the audience. This made Q&A a lot less painful then throwing a mic into the audience and hopefully understanding a word or two of the question. A great way to do Q&A.

Talks where very diverse ranging from technical to comical, so rather then slavishly describing each talk, I will try to weave it categorically and add some personal insights which where inspired by those talks.
