Performing controlled actions while streaming

[cacosandon]

I read the documentation, but I can't find anything related to executing actions while streaming, at least in React (NextJS).

For example, let's say I want to call my /api/completion endpoint from a component to update a specific state in a controlled way. What is the best approach for this?

It seems the best option is to call fetch to the API and handle SSE manually without the SDK, so I can perform actions per chunk received.

I noticed that onChunk is a property for streamText on the server but not available on the client. Why is that?

There are some workarounds, like the one in this pull request: #3252, but it's like something is off.

Any help would be much appreciated!
