In-App Notifications Not Showing
Your app should show notifications, toast messages, or alert popups for things like successful saves, errors, or new messages — but nothing appears. Users perform actions without any feedback.
Common Causes
- Notification component not mounted in the app's root layout
- Toast library imported but not initialized
- Z-index issues — notifications render behind other elements
- Notification state not connected to the actual event triggers
- CSS hiding the notification container
How to Fix It
- Check if the notification/toast component is included in your root layout
- Use browser DevTools to inspect if notification elements exist in the DOM but are hidden
- Check z-index values — notifications should have a high z-index (9999+)
- Verify the toast/notification function is being called in your event handlers
- Test by manually triggering a notification from the browser console

15+ years shipping production infrastructure for startups. Former CTO at qed.builders (acquired by The Sandbox).
Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

Get HelpFrequently Asked Questions
The notification component is in the code but nothing shows. Why?
The component might not be mounted in the root layout, or the z-index is too low so it renders behind other elements. Check the DOM and CSS.
Users don't know if their action succeeded. How important are notifications?
Very important for user experience. Without feedback, users click buttons multiple times or think the app is broken. A developer can add proper notification handling.
