## Description
Solid progress on the chat widget error handling and visual feedback
system.
### Key improvements:
- Added toast notifications for error states
- Enhanced streaming visual feedback with brand color glow
- Fixed loading state management with proper timeout handling
- Improved error recovery flow
### Previously...
Error states would leave the UI stuck in loading mode with no user
feedback:
````typescript path=packages/chat-widget/src/hooks/useStreamingChat.ts mode=EXCERPT
} catch (error) {
onError(error instanceof Error ? error.message : "Unknown error");
} finally {
setIsLoading(false);
}
````
### Now...
Comprehensive error handling with visual feedback and proper state
cleanup:
````typescript path=packages/chat-widget/src/hooks/useStreamingChat.ts mode=EXCERPT
// Set a timeout to reset loading state if no response
const timeoutId = setTimeout(() => {
setIsLoading(false);
onError("Request timed out");
}, 120000); // 2 minutes
} catch (error) {
clearTimeout(timeoutId);
onError(error instanceof Error ? error.message : "Unknown error");
// Add a final empty assistant message to clear the streaming state
onMessage({
role: "assistant",
content: "",
streaming: false,
});
} finally {
setIsLoading(false);
}
````
The timeout mechanism ensures that even if the client disconnects
mid-stream, the UI will automatically reset to allow the user to try
again. Toast notifications provide immediate feedback about what went
wrong, while the streaming visual effects use the brand color to create
a cohesive experience.
**Testing**: Use Chrome DevTools Network tab → set throttling to
"Offline" → send message → toggle back to "No throttling" to verify the
error recovery flow works properly.
