This is possible using a variety of desktop and server tools including geometric networks in ArcGIS Desktop, the ArcGIS Utility Network Management extension for ArcGIS Server/Enterprise, pgRouting, and via various QGIS plugins. However, the utility field crews and managers only have access to our web maps, so I wondered if I could program a Mapbox GL JS plugin to do some simple network tracing directly in the browser. Fortunately in my case the entire database is less than 3MB, so all the data can be loaded into the browser via GeoJSON. This data can then be visualized and analyzed using client-side libraries, in this instance Mapbox GL and Turf JS.
