How can I add attributes to a feature class?

JackFairfield

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,

Sounds like you are unfamiliar with dynamic workspaces.

The table must exist in a registered dynamic workspace in your Map Server.

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.
