kandi X-RAY | OL-DynamicMeasure Summary
Based on OpenLayers.Control.Measure, the DynamicMeasure control shows measurements on labels that follow the cursor. This avoids having to worry about preparing a DOM item to display measurements. The control also has preset styles to show lines and labels, so the only thing to do is add it to the map. Control allows displaying lengths and headings of the segments that form a polyline or a polygon.

how to label each side of a polygon with the length of the side?

It is easier to display labels using a vector style than with overlays used in that example, especially if you want to break the line into segments. OpenLayers 3 had limited text styling ability, with version 4 or above you can specify a background fill to make them look very much like the overlays, but this code is OpenLayers 3:
