Hi, this weekend I spend a lot of time tweaking and improving some stuff under the hood of Code Flow Canvas.. and I finally started building some unit/integration tests for the runtime flow engine as I want to reliably know when a flow is finished. I found some situations with certain node-types (the map and foreach node-types) that had some bugs in it that I didn't notice before. Also when the flow-engine was used in a none DOM environment there was a nasty bug somewhere deep in the system which caused nodes not to be reached... building tests for this really helped and save me some time debugging. All of this is important anyway but especially for the demo that I will give remotely at Live this year, because I don't want to surprise myself and anyone else 😊... In the attached screenshot you can see a new flow example that I made and hopefully make a video of next week: the K-Means clustering algorithm including visualisation of the clusters and centroids. You can already try it on demo.codeflowcanvas.io (it's in the examples).
