🎉 Integrated Error Store with Automatic Notifications

What's New

The error store now automatically creates PrimeVue Toast notifications when errors are set. No need to import both stores anymore!

✅ Benefits

• Single Import: Only import useErrorStore
• Automatic Notifications: Error toasts appear automatically
• Cleaner Code: Less boilerplate in components
• Consistent UI: All notifications use PrimeVue Toast
• Better Organization: All error handling in one place

📖 Usage Examples

Before (Old Way)

// Had to import both stores
import { useErrorStore } from "@/stores/errors";
import { useNotificationStore } from "@/stores/notifications-primevue";

const errorStore = useErrorStore();
const notificationStore = useNotificationStore();

// Manual notification creation
errorStore.setGlobalError(new Error("Something failed"));
notificationStore.addError("Something failed"); // Had to do this manually

After (New Way)

// Only need one import
import { useErrorStore } from "@/stores/errors";

const errorStore = useErrorStore();

// Automatic notification - toast appears automatically!
errorStore.setGlobalError(new Error("Something failed"));

🛠️ Available Methods

Error Methods (Auto-create toasts)

// Global errors
errorStore.setGlobalError(new Error("System error"));

// Component-specific errors
errorStore.setComponentError("form", new Error("Validation failed"));

// API errors
errorStore.setApiError("fetch-users", new Error("Network error"));

Convenience Methods (Direct notifications)

// Success messages
errorStore.setSuccess("Operation completed!");

// Warnings
errorStore.setWarning("Please check your input");

// Info messages
errorStore.setInfo("Loading data...");

Disable Automatic Notifications

// Set errors without showing toasts
errorStore.setGlobalError(new Error("Silent error"), false);
errorStore.setComponentError("form", new Error("Silent error"), false);

🔄 Migration Guide

Components Using Both Stores

Old Code:

import { useErrorStore } from "@/stores/errors";
import { useNotificationStore } from "@/stores/notifications-primevue";

const errorStore = useErrorStore();
const notificationStore = useNotificationStore();

// Show error
errorStore.setGlobalError(error);
notificationStore.addError("Failed to save");

New Code:

import { useErrorStore } from "@/stores/errors";

const errorStore = useErrorStore();

// Error toast shown automatically!
errorStore.setGlobalError(error);

API Wrapper Updates

The ApiWithToast wrapper has been updated to use only the error store. All existing usage remains the same, but now it's even simpler internally.

🎯 What Changed Internally

1. Error Store: Now imports notifications-primevue store
2. Automatic Calls: Error methods automatically call toast notifications
3. Formatted Titles: Component names are nicely formatted (e.g., "demo-component" → "Demo Component Error")
4. Convenience Methods: Added setSuccess(), setWarning(), setInfo() methods
5. ApiWithToast: Updated to use only error store
6. Demo Pages: Updated to show single-store usage

🧪 Testing

Visit /dev/error-handling-demo to test:

• All buttons now work with single error store
• Automatic toast notifications
• Error history still works
• Component errors formatted nicely

The notifications will appear in the top-right corner using PrimeVue Toast styling!
