In-App Notification Bell Not Showing New Notifications
Your Base44 app has a notification bell icon but it never shows new notifications, always displays zero, or shows an incorrect count. Users miss important updates because the notification system appears empty even when there are unread items waiting for them.
In-app notifications are how users learn about new assignments, status changes, mentions, and deadlines. When the bell is broken, users rely on email (which they may not check promptly) or manual browsing to discover updates. Response times slow down and important items fall through the cracks.
The issue may be that notifications are never created, that they're created but the badge count isn't updated, or that the bell component doesn't poll for new notifications after the initial page load.
Error Messages You Might See
Notification bell always shows 0
New notification not appearing in bell dropdown
Notification count doesn't decrease after reading
Notifications showing for wrong user
Common Causes
- Notification records not created — The workflow or trigger that should create notification records on events is not configured or not firing
- Badge count query wrong — The query counting unread notifications has a filter error, always returning zero
- No real-time polling — The notification bell checks for new items on page load only, never updating until a full page refresh
- User ID mismatch — Notifications are created but assigned to the wrong user or with a mismatched user identifier
- Mark-as-read not working — Once notifications are read, they're not properly flagged, causing either permanent badges or permanent zero counts
How to Fix It
- Verify notification creation — Check the notifications table in your database to confirm records are being created when triggering events occur
- Test the count query — Run the query that counts unread notifications for a specific user and verify it returns the correct number
- Add polling for new notifications — Set the notification bell to re-fetch the count every 30 seconds using a timer
- Verify user ID matching — Ensure the user ID stored in notification records matches the ID used to query them in the bell component
- Test the full notification lifecycle — Create a notification, verify the bell shows it, click it, and verify it marks as read and the count decreases

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Get HelpFrequently Asked Questions
Why does my Base44 notification bell always show zero?
Check three things: 1) Are notification records actually being created in the database? 2) Does the count query filter by the correct user ID? 3) Is the query filtering for unread status correctly? One of these is likely misconfigured.
How often should the notification bell check for new items?
Poll every 30 seconds for a good balance between responsiveness and server load. For truly real-time notifications, use WebSocket subscriptions if Base44 supports them.
