unclear on the relationship between copilotkit/graphql/ag-ui

[Cyronius]

I started reading the ag-ui protocol spec and implementing ag-ui on top of google-adk, threw copilotkit into a quick frontend, and I was a bit surprised to see it sending graphql instead of ag-ui. Would someone mind explaining the relationship between copilotkit and the ag-ui protocol, and how it's intended for me to use copilotkit with a server ag-ui implementation?

I'm sure this is covered somewhere and I'm missing something obvious.

I figured it out -- the answers are here for anyone else confused by this. Essentially, copilotkit depends on a nextjs server that handles the graphql <-> ag-ui translation. If you want to use copilotkit you must either handle the graphql translation layer yourself or use the provided nextjs server.

I don't understand yet if this is an architectural necessity, or just a choice made by the copilotkit devs.
