ahmad2b/canvas-callback
This open-source project & guide shows you exactly how to implement Canvas UX pattern + LangGraph human-in-the-loop workflows in your AI apps.
Implements type-based interrupt routing within LangGraph's execution engine to enable structured UI collection (e.g., destination selection, itinerary building) alongside persistent canvas workspaces. Built with a modular architecture separating chat messaging, canvas rendering, and interrupt handlers that communicate with a LangGraph server backend. Targets collaborative AI applications across travel planning, education, data analysis, and design domains using Node.js frontend with Python/LangGraph agent infrastructure.
