I built an AI chat interface. I wanted word-by-word responses. It failed. Responses cut off mid-word.

I increased the timeout. It did not work. I tried retry loops. This caused duplicate words. I tried buffering. This made the app slow.

The cause was a parsing error. The API sends JSON-LD lines. My code stopped before the stream ended. It ignored the end signal.

The solution:

• Use bytes instead of lines.
• Manage the buffer manually.
• Look for the [DONE] signal.
• Keep the connection open.

Then the frontend froze. React updated too fast. I throttled the server to fix this.

Tips for you:

• Read the streaming spec.
• Find the explicit end event.
• Use SSE libraries.
• Track your data.

Never trust a stream to end gracefully.

What is your weirdest streaming bug?
