2. Development Tips

  • State Management: Use persistent storage for chat history.
  • Error Handling: Gracefully handle disconnections and retries.
  • Testing: Simulate high traffic to ensure stability.

3. Performance Optimization

  • Compress data payloads to reduce bandwidth usage.
  • Cache frequently accessed messages.
  • Optimize server response times with load balancing.
