Vercel AI SDK: How do I make this work with a separate Node JS Backend

Help
1

Frontend is built using Next JS:

  • I used the older Vercel AI Chatbot template built using AI Vercel SDK (RSC one).
    Link: Next.js AI Chatbot 2.0 - Vercel
  • I am migrating it from RSC to UI SDK.

Backend is multiple services, but frontend is integrating with a Node JS application:

  • This node JS application is using SSE to stream response from the BE to the FE.

The Issue:

  • I want to use the UI capabilities provided by AI SDK, but my AI interactions are happening not directly using things like useAssistant(), but using a Node JS backend.

Question:

  • Does the AI SDK even allow this?
  • Is it worth doing it this way?
  • Are there any similar use-cases that I can refer to resolve my issue?

Please pin point if any extra information is necessary for this.
