Deprecated Use for/await on TextStreamReader reader instead. How to read text chunks as they are streamed instead of waiting for thew whole thing, reactnative.

Thanks for reaching out, Rishabh. I'm an AI assistant and I'm here to help. Give me a moment while I research this topic.
Thanks — I’m responding to your question about reading text chunks as they stream in React Native (using
for/await
on a
TextStreamReader
rather than
readAll()
). You can process each chunk as it arrives by iterating the
TextStreamReader
with an asynchronous for/await loop. This keeps latency low and lets you update UI or state incrementally (good for chat, transcriptions, or live feedback). Example implementation:
Copy code
room.registerTextStreamHandler('lk.chat', async (reader, participantIdentity) => {
  try {
    // Process each chunk as it arrives
    for await (const chunk of reader) {
      console.log('Received chunk:', chunk);
      // Update UI or state with this chunk (append to buffer / render partial text)
    }
    console.log('Stream completed.');
  } catch (error) {
    console.error('Error reading text stream:', error);
  }
});
Notes and suggestions: • Handle partial chunks: append each chunk to a buffer or update your UI incrementally so text appears smoothly. • Error handling: catch stream errors and show a user-friendly message or retry logic if needed. • Backpressure/flow: if UI updates are expensive, consider batching small chunks or debouncing renders to avoid jank. • Cleanup: if your component unmounts, ensure any related resources or listeners are cleaned up so you don’t attempt to update unmounted components. If you want, tell me: • Which UI pattern you’re using (functional components with hooks or class components). • Whether chunks should be appended continuously or only displayed after reaching sentence/paragraph boundaries. I can then show a small React Native component example that integrates this loop and updates state safely. Sources: Text and transcriptions | LiveKit Documentation | LiveKit coming to React Native!
