🎨 Customization

Positions

toast.configure({ position: 'top-right' });    // Top right corner
toast.configure({ position: 'top-left' });     // Top left corner
toast.configure({ position: 'bottom-right' }); // Bottom right corner (default)
toast.configure({ position: 'bottom-left' });  // Bottom left corner
toast.configure({ position: 'top-center' });   // Top center
toast.configure({ position: 'bottom-center' }); // Bottom center

Custom Styling

// Individual toast styling
toast.success('Custom styled toast', {
  backgroundColor: '#1f2937',
  textColor: '#f9fafb',
  borderColor: '#10b981'
});

// Global custom CSS
toast.configure({
  customCSS: `
    .mt-toast {
      border-radius: 16px;
      backdrop-filter: blur(10px);
    }
    .mt-toast-title {
      font-weight: 700;
    }
  `
});

Animation Control

toast.configure({
  enableBorderAnimation: true,    // Enable signature border animations
  enableFillAnimation: true,      // Enable fill progress animations
  animationDuration: 300,         // Animation duration in ms
  animationDirection: 'left-to-right', // Animation direction
  stackOffsetY: 12,              // Vertical stacking offset
  stackOffsetX: 6,               // Horizontal stacking offset
  scaleDecrementPerLevel: 0.03,  // Scale reduction per stack level
  opacityDecrementPerLevel: 0.15 // Opacity reduction per stack level
});

Animation Directions

Choose from four different animation styles for both border and fill animations:

// Left to right (default)
toast.success('Left to right animation', {
  animationDirection: 'left-to-right'
});

// Right to left
toast.error('Right to left animation', {
  animationDirection: 'right-to-left'
});

// Top to bottom
toast.info('Top to bottom animation', {
  animationDirection: 'top-to-bottom'
});

// Bottom to top
toast.warning('Bottom to top animation', {
  animationDirection: 'bottom-to-top'
});

// Set globally for all toasts
toast.configure({
  animationDirection: 'right-to-left'
});

Enhanced Pause on Hover

ModernToasts provides advanced pause functionality with background toast control:

// Global configuration for background toast pause
toast.configure({
  pauseBackgroundToastsOnHover: true  // Default: true
});

// Individual toast pause control
toast.success('Message', {
  pauseOnHover: true  // Default: true
});

// When hovering over any toast:
// - Current toast: timer + animations pause
// - Background toasts: timer + animations pause (if configured)
// - Perfect timing consistency maintained

// Disable background pause for individual control
toast.configure({
  pauseBackgroundToastsOnHover: false
});
// Now only the hovered toast pauses, others continue

🔧 Advanced Usage

Multiple Instances

import { ModernToasts } from 'modern-toasts';

// Create separate instances with different configs
const topToasts = new ModernToasts({
  position: 'top-right',
  maxVisibleStackToasts: 2
});

const bottomToasts = new ModernToasts({
  position: 'bottom-left',
  enableBorderAnimation: false
});

topToasts.success('Top notification');
bottomToasts.info('Bottom notification');

Event Listeners

// Listen to toast events
toast.on('show', (toastData) => {
  console.log('Toast shown:', toastData);
});

toast.on('dismiss', (toastData) => {
  console.log('Toast dismissed:', toastData);
});

// Remove event listeners
toast.off('show', callback);

Custom Icons

toast.success('Custom icon toast', {
  icon: '<svg>...</svg>' // Your custom SVG icon
});
