Summary
Standalone
examples/ag-ui/— a single-conversation chat app over the AG-UI transport + a uvicornag-ui-langgraphbackend running the (duplicated) a2ui graph. Demonstrates LangGraph↔AG-UI transport + a2ui parity. Runnable vianx serve+uvicorn.examples/ag-ui/python/— chat a2ui graph duplicated verbatim (transport-agnostic) +server.py(ag-ui-langgraph, token-optional auth,/ok, localMemorySavercheckpointer for the standalone path).examples/ag-ui/angular/— simplified single-conversation<chat>host viaprovideAgent({ url: '/agent' }). No@threadplane/langgraph— the entire delta fromexamples/chatis the transport provider.LangGraphThreadsAdapter(thread CRUD) has no AG-UI equivalent. Relies on thecustomEventssignal (feat(ag-ui): customEvents signal for live a2ui streaming parity #606) for live a2ui.Verified locally:
