Export utils to parse AI stream responses on the client about ai

[xl0]

Can only second @wong2 . I love the server-side stuff because it abstracts away the differences between providers, but the UI part just feels wrong. I would very much prefer simple building blocks that you can use individually, and then, fine, put a useChat on top of them. Right now useChat is complicated because it's the only official way to handle the server responses, and thus it's hard to use for anything non-standard. I don't think the solution is to extend useChat even further, but rather to expose the building blocks so people can handle their use-case on their own.

This is great, since we want to document the protocol in the coming weeks. Can you share which exact functionality / functions you would need to access? some of it is exposed but not documented

[wong2]

Our user cases include:

• simple text chat
• tool calling: call search API if needed, then answer based on search result

@wong2 we have started documenting the data stream protocol: https://sdk.vercel.ai/docs/ai-sdk-ui/stream-protocol#data-stream-protocol

The @ai-sdk/ui-utils package exposes utilities for formatting and parsing these stream parts (warning: the api is internal/unstable and might change).

Great!
