[ENHANCEMENT] Replace browser alerts with professional toast notifications for better UX #71
Description
🐛 Problem
The application currently uses browser alert() dialogs for user notifications, which provides a poor user experience:
- Browser alerts are blocking and interrupt user workflow
- They look unprofessional and outdated
- Cannot be styled to match the application design
- Interrupt user interactions and force immediate attention
📍 Current Behavior
Browser alerts are used in several components:
- Login success:
alert("Login successful!") - Signup success:
alert("Signup successful! Welcome") - Watchlist actions:
alert("Stock added to watchlist!") - Error messages:
alert("Failed to add to watchlist.")
✨ Proposed Solution
Replace browser alerts with a modern toast notification system that:
- Shows non-blocking notifications in the corner
- Auto-dismisses after a few seconds
- Supports different types (success, error, warning, info)
- Has smooth animations and professional styling
- Allows multiple notifications to stack
- Can be dismissed by clicking
🎯 Expected Benefits
- Better UX: Non-intrusive notifications
- Professional Look: Styled to match app design
- Modern Standards: Following current web development practices
- Accessibility: Better for screen readers and keyboard navigation
📱 Examples of Good Toast Systems
- React Hot Toast
- Material-UI Snackbars
- Custom toast notifications with smooth animations
🔧 Implementation Approach
- Create a notification context and provider
- Build reusable toast components
- Replace all existing alert() calls
- Add auto-dismiss functionality
- Support different notification types
📸 Screenshots/Examples
Current: Browser alert blocks the entire interface
Proposed: Toast notification appears in corner without blocking
