Hi @koop_g. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave: ---------------------- To implement notifications in your refine MUI application with a custom WebSocket backend, you'll need to set up both the notification provider and UI elements. Here's how to do it: Setting up MUI Notifications Refine's Material UI integration uses the notistack library for notifications. You'll need to: 1. Set up the RefineSnackbarProvider and use the built-in notification provider:

import { Refine } from "@refinedev/core";
import {
  useNotificationProvider,
  RefineSnackbarProvider,
} from "@refinedev/mui";

const App = () => {
  return (
    <RefineSnackbarProvider>
      <Refine 
        notificationProvider={useNotificationProvider}
        // other refine props
      >
        {/* Your app components */}
      </Refine>
    </RefineSnackbarProvider>
  );
};

import { Refine } from "@refinedev/core";
import {
  useNotificationProvider,
  RefineSnackbarProvider,
} from "@refinedev/mui";

const App = () => {
  return (
    <RefineSnackbarProvider>
      <Refine 
        notificationProvider={useNotificationProvider}
        // other refine props
      >
        {/* Your app components */}
      </Refine>
    </RefineSnackbarProvider>
  );
};

The RefineSnackbarProvider is a wrapper around notistack's SnackbarProvider that adds theme compatibility as mentioned in the documentation. Integrating with WebSocket Backend To integrate with your custom WebSocket backend: 1. Create a custom hook to handle WebSocket connections and messages:

import { useEffect } from "react";
import { useNotification } from "@refinedev/core";
export const useWebSocketNotifications = (socketUrl) => {
  const { open } = useNotification();
  
  useEffect(() => {
    const socket = new WebSocket(socketUrl);
    
    socket.onmessage = (event) => {
      const data = JSON.parse(event.data);
      
      // Display notification based on the message from your WebSocket
      open({
        type: data.type, // "success", "error", or "progress"
        message: data.title,
        description: data.message,
        key: data.id, // Use a unique ID from your notification
      });
    };
    
    socket.onclose = () => {
      // Handle reconnection logic if needed
    };
    
    return () => {
      socket.close();
    };
  }, [socketUrl, open]);
};

import { useEffect } from "react";
import { useNotification } from "@refinedev/core";
export const useWebSocketNotifications = (socketUrl) => {
  const { open } = useNotification();
  
  useEffect(() => {
    const socket = new WebSocket(socketUrl);
    
    socket.onmessage = (event) => {
      const data = JSON.parse(event.data);
      
      // Display notification based on the message from your WebSocket
      open({
        type: data.type, // "success", "error", or "progress"
        message: data.title,
        description: data.message,
        key: data.id, // Use a unique ID from your notification
      });
    };
    
    socket.onclose = () => {
      // Handle reconnection logic if needed
    };
    
    return () => {
      socket.close();
    };
  }, [socketUrl, open]);
};

2. Use this hook in your app:

const App = () => {
  useWebSocketNotifications("wss://your-websocket-endpoint");
  
  return (
    // Your app components
  );
};

const App = () => {
  useWebSocketNotifications("wss://your-websocket-endpoint");
  
  return (
    // Your app components
  );
};

Manually Triggering Notifications You can also manually trigger notifications from anywhere in your application using the useNotification hook:

import { useNotification } from "@refinedev/core";

const YourComponent = () => {
  const { open, close } = useNotification();
  
  const showNotification = () => {
    open({
      type: "success",
      message: "Notification Title",
      description: "This is the content of the notification.",
      key: "notification-key",
    });
  };
  
  const closeNotification = () => {
    close("notification-key");
  };
  
  return (
    <Button onClick={showNotification}>Show Notification</Button>
  );
};

import { useNotification } from "@refinedev/core";

const YourComponent = () => {
  const { open, close } = useNotification();
  
  const showNotification = () => {
    open({
      type: "success",
      message: "Notification Title",
      description: "This is the content of the notification.",
      key: "notification-key",
    });
  };
  
  const closeNotification = () => {
    close("notification-key");
  };
  
  return (
    <Button onClick={showNotification}>Show Notification</Button>
  );
};

This approach gives you the flexibility to display notifications based on both WebSocket events and user interactions as shown in the documentation examples. The notification system supports different types ("success", "error", "progress") and allows you to provide a unique key to manage notifications programmatically. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Let me check the knowledge base for you again. One moment! :books: ---------------------- To implement a notification icon with a dropdown list in the top bar of your refine MUI application, you can customize the default layout. Here's how to create this notification feature: Creating a Notification Icon with Dropdown You can add a notification icon to the header by customizing the ThemedLayoutV2 component. Here's a step-by-step implementation:

import React, { useState } from "react";
import { 
  IconButton, 
  Badge, 
  Menu, 
  MenuItem, 
  ListItemText, 
  Typography,
  Box
} from "@mui/material";
import NotificationsIcon from "@mui/icons-material/Notifications";
import { useNotification } from "@refinedev/core";
import { ThemedHeaderV2 } from "@refinedev/mui";

// Custom notification item component
const NotificationItem = ({ notification, onClose }) => {
  return (
    <MenuItem onClick={onClose}>
      <ListItemText 
        primary={notification.message}
        secondary={notification.description}
      />
    </MenuItem>
  );
};
// Custom header with notification icon
const CustomHeader = () => {
  const [anchorEl, setAnchorEl] = useState(null);
  const [notifications, setNotifications] = useState([
    // Example notifications - replace with your WebSocket data
    { id: 1, message: "New message", description: "You have a new message" },
    { id: 2, message: "Update available", description: "System update available" }
  ]);
  
  const handleClick = (event) => {
    setAnchorEl(event.currentTarget);
  };
  
  const handleClose = () => {
    setAnchorEl(null);
  };
  
  return (
    <ThemedHeaderV2
      // Other header props
      extra={
        <Box sx={{ display: "flex", alignItems: "center" }}>
          <IconButton color="inherit" onClick={handleClick}>
            <Badge badgeContent={notifications.length} color="error">
              <NotificationsIcon />
            </Badge>
          </IconButton>
          
          {/* User avatar would go here */}
          
          <Menu
            anchorEl={anchorEl}
            open={Boolean(anchorEl)}
            onClose={handleClose}
            PaperProps={{
              sx: { width: 320, maxHeight: 450, overflow: 'auto' }
            }}
          >
            {notifications.length > 0 ? (
              <>
                <Typography variant="subtitle1" sx={{ p: 2, pb: 0 }}>
                  Notifications
                </Typography>
                {notifications.map((notification) => (
                  <NotificationItem 
                    key={notification.id} 
                    notification={notification} 
                    onClose={handleClose}
                  />
                ))}
              </>
            ) : (
              <MenuItem disabled>
                <ListItemText primary="No notifications" />
              </MenuItem>
            )}
          </Menu>
        </Box>
      }
    />
  );
};
// Use this custom header in your ThemedLayoutV2
const CustomLayout = ({ children }) => {
  return (
    <ThemedLayoutV2 Header={CustomHeader}>
      {children}
    </ThemedLayoutV2>
  );
};

import React, { useState } from "react";
import { 
  IconButton, 
  Badge, 
  Menu, 
  MenuItem, 
  ListItemText, 
  Typography,
  Box
} from "@mui/material";
import NotificationsIcon from "@mui/icons-material/Notifications";
import { useNotification } from "@refinedev/core";
import { ThemedHeaderV2 } from "@refinedev/mui";

// Custom notification item component
const NotificationItem = ({ notification, onClose }) => {
  return (
    <MenuItem onClick={onClose}>
      <ListItemText 
        primary={notification.message}
        secondary={notification.description}
      />
    </MenuItem>
  );
};
// Custom header with notification icon
const CustomHeader = () => {
  const [anchorEl, setAnchorEl] = useState(null);
  const [notifications, setNotifications] = useState([
    // Example notifications - replace with your WebSocket data
    { id: 1, message: "New message", description: "You have a new message" },
    { id: 2, message: "Update available", description: "System update available" }
  ]);
  
  const handleClick = (event) => {
    setAnchorEl(event.currentTarget);
  };
  
  const handleClose = () => {
    setAnchorEl(null);
  };
  
  return (
    <ThemedHeaderV2
      // Other header props
      extra={
        <Box sx={{ display: "flex", alignItems: "center" }}>
          <IconButton color="inherit" onClick={handleClick}>
            <Badge badgeContent={notifications.length} color="error">

            </Badge>
          </IconButton>
          
          {/* User avatar would go here */}
          
          <Menu
            anchorEl={anchorEl}
            open={Boolean(anchorEl)}
            onClose={handleClose}
            PaperProps={{

            }}

            {notifications.length > 0 ? (
              <>
                <Typography variant="subtitle1" sx={{ p: 2, pb: 0 }}>
                  Notifications
                </Typography>
                {notifications.map((notification) => (
                  <NotificationItem 
                    key={notification.id} 
                    notification={notification} 
                    onClose={handleClose}
                  />
                ))}
              </>
            ) : (
              <MenuItem disabled>
                <ListItemText primary="No notifications" />
              </MenuItem>
            )}
          </Menu>
        </Box>
      }
    />
  );
};
// Use this custom header in your ThemedLayoutV2
const CustomLayout = ({ children }) => {
  return (
    <ThemedLayoutV2 Header={CustomHeader}>
      {children}
    </ThemedLayoutV2>
  );
};

Integrating with WebSocket Notifications To connect this UI with your WebSocket backend:

import { useEffect } from "react";

// Inside your CustomHeader component
const CustomHeader = () => {
  const [notifications, setNotifications] = useState([]);
  
  useEffect(() => {
    const socket = new WebSocket("wss://your-websocket-endpoint");
    
    socket.onmessage = (event) => {
      const newNotification = JSON.parse(event.data);
      setNotifications(prev => [newNotification, ...prev]);
    };
    
    return () => {
      socket.close();
    };
  }, []);
  
  // Mark notification as read when clicked
  const handleNotificationClick = (id) => {
    // Send read status to your backend if needed
    setNotifications(prev => 
      prev.filter(notification => notification.id !== id)
    );
    handleClose();
  };
  
  // Rest of the component as above
};

import { useEffect } from "react";

// Inside your CustomHeader component
const CustomHeader = () => {
  const [notifications, setNotifications] = useState([]);
  
  useEffect(() => {
    const socket = new WebSocket("wss://your-websocket-endpoint");
    
    socket.onmessage = (event) => {
      const newNotification = JSON.parse(event.data);
      setNotifications(prev => [newNotification, ...prev]);
    };
    
    return () => {
      socket.close();
    };
  }, []);
  
  // Mark notification as read when clicked
  const handleNotificationClick = (id) => {
    // Send read status to your backend if needed
    setNotifications(prev => 
      prev.filter(notification => notification.id !== id)
    );
    handleClose();
  };
  
  // Rest of the component as above
};

Using the Custom Layout Finally, use your custom layout in your app:

import { Refine } from "@refinedev/core";
import { useNotificationProvider, RefineSnackbarProvider } from "@refinedev/mui";

const App = () => {
  return (
    <RefineSnackbarProvider>
      <Refine 
        notificationProvider={useNotificationProvider}
        // other refine props
      >
        <Routes>
          <Route
            element={<CustomLayout />}
          >
            {/* Your routes */}
          </Route>
        </Routes>
      </Refine>
    </RefineSnackbarProvider>
  );
};

import { Refine } from "@refinedev/core";
import { useNotificationProvider, RefineSnackbarProvider } from "@refinedev/mui";

const App = () => {
  return (
    <RefineSnackbarProvider>
      <Refine 
        notificationProvider={useNotificationProvider}
        // other refine props
      >
        <Routes>
          <Route
            element={<CustomLayout />}
          >
            {/* Your routes */}
          </Route>
        </Routes>
      </Refine>
    </RefineSnackbarProvider>
  );
};

This implementation gives you a notification icon in the header that displays a badge with the count of unread notifications. When clicked, it opens a dropdown menu showing the list of notifications that users can interact with. You can further customize the notification items, add actions like "mark all as read," or implement pagination for a large number of notifications based on your specific requirements. ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
