Just like we did with ArcGIS Runtime 100.6 in late 2019, we have been working ever since to bring the capabilities of the utility network to the Javascript API. We are pleased to announce that the first cut of the utility network API is now available on ArcGIS Javascript API 4.20. In this blog post we discuss what’s new in ArcGIS Utility Network for Javascript, illustrate few code samples and finally discuss what’s coming in future releases.
