Nearly two years after the release of version 2.0 and two months from the latest 2.9, Microsoft has released the newest version of TypeScript – the language we use in our projects. Let’s see what changes have been made and how they can affect our daily work. In TypeScript 3.0 we can identify just five changes affecting the you can use the language. Only one of those is flagged as a breaking change. But that’s enough introduction, let’s see what’s new!

Diagram after proper configuration of the ports A palette is a separate canvas that displays all the nodes defined in it and allows you to transfer them to the main diagram. It is configured in a manner analogical to the diagram, but through the creation of a go.Palette object. However, in order to do this, we should first…

In the last post I showed you how to get started with a GoJS application. I explained how to create a diagram and how to present data using it. Let’s go a step further. Figure 1. Diagram with three templates for nodes While our diagram is starting to look better, there are a few issues that stick out. First – it can’t be edited (the only thing you can do is move the nodes around and clone them using the CTRL key), and second – we might want the edges to be drawn between specific points of the nodes. This is particularly visible in…
