Vercel AI SDK Migration

I can help you with this migration issue. The readDataStream function is mentioned in the troubleshooting documentation but not explicitly in the migration guides 1.

Based on the AI SDK documentation, it appears that the readDataStream function was part of the internal API in version 3.3, and it might have been removed or relocated in newer versions. This is likely why you're not seeing it in the package exports anymore.

Here are a few options to address this issue:

Use the Stream Data Protocol: If you were using readDataStream to process stream data, you can now use the documented stream data protocol 1. The AI SDK switched to this protocol in version 3.0.20 and later.
Alternative Approach: Instead of using readDataStream, you can process the stream using the newer API methods:

// If you're using useChat/useCompletion
const { messages } = useChat({
  streamProtocol: 'text', // Use this instead of the older streamMode
  // ...other options
});

// Or if you're using streamText directly
const result = streamText({
  model: openai('gpt-4o'),
  prompt: 'Your prompt here',
  onChunk: ({ chunk }) => {
    if (chunk.type === 'text-delta') {
      // Process the text chunk
      console.log(chunk.text);
    }
  },
});

Pin to an Earlier Version: If you need time to refactor your code, you could temporarily pin to version 3.0.19 which still had the raw text stream 1.

If you need more specific guidance, could you share how you were using readDataStream in your application? That would help me provide more targeted migration advice.
