I have a feature layer of points whose only attribute is an ID that matches up to a table of data. How can I perform a "join" on the client side using the esri javascript api 4.x version so that the attributes from the corresponding table row exist in the feature layer and I can set definition expressions and use the attributes in popups.
Jack,
Look here:

Sample:
MapImageLayer - dynamic data layer with table join | ArcGIS API for JavaScript 4.6
Sounds like you are unfamiliar with dynamic workspaces.
The table must exist in a registered dynamic workspace in your Map Server.
Enabling dynamic layers on a map service in ArcGIS Desktop—Documentation | ArcGIS Enterprise
Do you happen to know where I can find the 'workspaceId' and 'dataSourceName' properties to use in this solution? I can't seem to find them through the ArcGIS Server Manager.
This looks amazing. Thank you so much for the pointer Robert. I'll give it a shot and post back with my experience.
