Quick NPM tip: don’t forget to uninstall node modules
Tue, Jul 4th 2017 4:08p   Frank van der Linden
NPM is great tool to have all your Node modules in your front end project, and don’t have to worry about dependencies. When you find a useful module for your project just do ‘npm install –save-dev’ and you are ready to go, but….. it can pollute your node_modules directory with unused node modules. Just uninstall your unused node module by ‘npm uninstall ’ by The post Quick NPM tip: don’t forget to uninstall node modules appeared first on elstar

Angular 4 bug in combination with latest Typescript
Sat, Jul 1st 2017 10:51a   Frank van der Linden
When we upgraded our Angular app to the latest version. We noticed everything worked with version 4.2.3 and Typescript 2.4. The problem After we reinstalled all the nom packages the Angular version was upgraded to 4.2.4, because we had in our package.json ‘^4.2.3’ for Angular packages. When we package everything and republished the app to the page, we got errors, huh!!!! The solution After some search I found it has to do with the combination of Typescript and Angular

Angular and base64 encoding and decoding
Fri, Jun 30th 2017 7:32p   Frank van der Linden
Currently I am busy building a Proof of Concept at my customer. We are using Springboot for the Backend services, which get data from Tridion and store data in a Oracle database.. The Front end is build with Angular. We started with version 2 with Grunt as build tool, but quickly we changed it to Angular 4 with Webpack. The overall feeling of Angular 4 and Webpack was much better. Another plus was the smaller footprint. Base64 Last request was to store some information in Cookie. Overall no ro

Bulk import in a Cloudant database
Thu, Apr 27th 2017 5:02p   Frank van der Linden
After some issues with HR Assistant I was thinking it would be a good idea to create a separate database with only the Design documents as schema database. So I replicated all the documents from the original database to a brand new one and called it hrassistant_schema. After the successful replication I kept all only the design documents. Today I got a question about the schemas and discovered it should also be a good idea to add all the configuration documents to the schema database of HR Ass

Fri, Apr 7th 2017 11:27a   Frank van der Linden
As promised in a previous blogpost, I will zoom in on the technologies I have seen and used at IBM InterConnect I was surprised the amount of technical sessions at InterConnect. More then I then was expecting as lots of people told me It was all about middleware. Below my impression as a developer Open Tech Summit On Sunday InterConnect for me started with the Open Tech Summit, a gathering of tech nerds, to learn more on Open Source software.

IBM InterConnect 2017 – something completely different
Tue, Mar 28th 2017 4:43p   Frank van der Linden
IBM InterConnect 2017 is over, I must say I totally enjoyed it. Lots of attendees, it was crowded everywhere, but it gave a good vibe.  I have met a lot of new people I heard that it was Lotusphere in the old days. I totally agree with the blog by Gabriella Davis, it is time to get out our own yellow bubble and integrate it in InterConnect. There is so much both worlds can learn from each other.

New Release: Generic XPages and HTML Widget For IBM Connections 5.5
Thu, Mar 2nd 2017 5:41p   Frank van der Linden
Yesterday I have created a new release of the OpenNTF project, Generic XPages and HTML Widget For IBM Connections. There was a problem with the widgets in IBM Connections 5.5, which was caused by some tags who were not in the expected DOM structure and small problem in the javascript. But many thanks to Christoph Stoettner of Panagenda who found the solution and provided me the modified files to release. Christoph, Thank you very much for the time you spent on this.

My take on IBM Connect 2017
Mon, Feb 27th 2017 12:30p   Frank van der Linden
IBM Connect went to the west coast of the USA, to the famous Moscone Center in the middle of San Francisco. Last week I have attended and spoken at IBM Connect. Here are some thoughts about the event. San Francisco I had visited San Francisco for 3 years as end point of our road trip through the west coast. I found it and still do it a pleasant city. Not that all American, but with a bit of Europe. It is a very expensive city, especially the hotels. I stayed at Powell Street near Market Street

Fri, Feb 3rd 2017 10:33a   Frank van der Linden
In Januari I started on a new role, Full Stack developer at Rabobank. One of the developers in my team is a big fan of IntelliJ from JetBrains, so I gave it a try over the past weeks. I must say I don’t miss Eclipse at all. Currently I am running it on macOS, but also in a VDI of the customer, which runs Windows. What is IntelliJ It is a very complete IDE, not for Java development only, but also Front end development, like AngularJS, because WebStorm is part of IntelliJ Ultimate. Lots o

Is the time of the year to have some time to reflect.

Over the last months we build the HR Assistant for the ICS World Wide Development Competition. The backend of the code is totally written in Java.

I will be speaking, again, at IconUK in September in London During my holiday I already received an notification that one of my abstracts was accepted. Till last week I didn’t know which session was accepted, but now I know Servlets made easy. Write once and run everywhere. Since a few years the Domino server is a real Java server. Which give you plenty of new opportunities, such as real servlets. Get and post data to any database via a Java servlet. Develop once, run everywhere.
