🆕 Latest Developer Experience Improvements

Auto-Generated index.ts Exports

Automatically generates clean index.ts files with all component exports for seamless importing:

// Auto-generated in your output directory
export { ArrowLeft } from './ArrowLeft';
export { ArrowRight } from './ArrowRight';
// ... all your components

Enhanced Props & Styling

Components now support comprehensive prop interfaces with React.forwardRef:

<Icon className="custom-class" style={{ color: 'red' }} size={32} />

Comprehensive File Protection

Lock files to prevent accidental modifications during builds:

svger-cli lock ./icons/critical-logo.svg  # Protects during all operations

� Why SVGER-CLI? The Zero-Dependency Advantage

In a landscape cluttered with heavy, single-framework tools, SVGER-CLI stands alone. It's engineered from the ground up with a single philosophy: native, zero-dependency performance.

• No node_modules bloat: Drastically smaller footprint.
• Faster installs: Perfect for CI/CD and rapid development.
• Unmatched security: No third-party vulnerabilities.
• Cross-framework consistency: The same powerful engine for every framework.

This lean approach delivers up to 85% faster processing and a 90% smaller bundle size compared to alternatives that rely on dozens of transitive dependencies.

📦 Installation

Install globally for access to the svger-cli command anywhere.

npm install -g svger-cli

Or add it to your project's dev dependencies:

npm install --save-dev svger-cli

---

🚀 Quick Start: Your First Conversion

1. Place your SVGs in a directory (e.g., ./my-svgs).

2. Run the build command:

   # Convert all SVGs to React components (default)
   svger-cli build ./my-svgs ./components

3. Use your components: An index.ts is auto-generated for easy imports.

   // Your app's component
   import { MyIcon, AnotherIcon } from './components';
   
   function App() {
     return (
       <div>
         <MyIcon className="text-blue-500" />
         <AnotherIcon size={32} style={{ color: 'red' }} />
       </div>
     );
   }

🌐 Multi-Framework Usage Guide

SVGER-CLI brings a unified, powerful experience to every major framework. Select your target with the --framework flag.

React

Generate optimized React components with forwardRef, memo, and TypeScript interfaces.

svger-cli build ./my-svgs ./react-components --framework react

Generated React Component (.tsx):

import * as React from 'react';

interface IconProps extends React.SVGProps<SVGSVGElement> {
  size?: number;
}

const MyIcon: React.FC<IconProps> = React.memo(
  React.forwardRef<SVGSVGElement, IconProps>(({ size = 24, ...props }, ref) => (
    <svg
      ref={ref}
      width={size}
      height={size}
      viewBox="0 0 24 24"
      {...props}
    >
      {/* SVG content */}
    </svg>
  ))
);

MyIcon.displayName = 'MyIcon';
export default MyIcon;

Vue 3

Choose between Composition API (--composition) or Options API.

🚀 Example 2: Production Setup (Intermediate)

Professional setup with configuration and optimization:

# Initialize with custom configuration
svger-cli init --framework react --typescript --interactive

# Generated .svgerconfig.json:
{
  "source": "./src/assets/icons",
  "output": "./src/components/icons",
  "framework": "react",
  "typescript": true,
  "forwardRef": true,
  "parallel": true,
  "batchSize": 15,
  "responsive": {
    "breakpoints": ["sm", "md", "lg"],
    "values": {
      "width": ["16px", "24px", "32px"]
    }
  }
}

# Build with optimizations
svger-cli build --performance --cache

# Start development mode
svger-cli watch --debounce 500 --verbose

Generated Components:

// Auto-generated: src/components/icons/ArrowLeft.tsx
import React from 'react';

interface ArrowLeftProps extends React.SVGProps<SVGSVGElement> {
  size?: number | 'sm' | 'md' | 'lg';
}

const ArrowLeft = React.forwardRef<SVGSVGElement, ArrowLeftProps>(
  ({ size = 24, className, style, ...props }, ref) => {
    const sizeValue = typeof size === 'string' 
      ? { sm: 16, md: 24, lg: 32 }[size] 
      : size;

    return (
      <svg
        ref={ref}
        width={sizeValue}
        height={sizeValue}
        viewBox="0 0 24 24"
        fill="none"
        className={className}
        style={style}
        {...props}
      >
        <path d="M19 12H5M12 19l-7-7 7-7" stroke="currentColor" strokeWidth="2"/>
      </svg>
    );
  }
);

ArrowLeft.displayName = 'ArrowLeft';
export default ArrowLeft;

Auto-generated index.ts:

/**
 * Auto-generated icon exports
 * Import icons: import { ArrowLeft, Home } from './components/icons'
 */
export { default as ArrowLeft } from './ArrowLeft';
export { default as Home } from './Home';
export { default as User } from './User';

// Default export for flexible importing
export default {
  ArrowLeft,
  Home,
  User,
};

Usage in App:

import { ArrowLeft, Home, User } from './components/icons';

function Navigation() {
  return (
    <nav className="flex items-center space-x-4">
      <ArrowLeft 
        size="sm" 
        className="text-gray-600 hover:text-gray-900" 
        onClick={() => history.back()}
      />
      <Home 
        size={28} 
        style={{ color: 'var(--primary-color)' }}
      />
      <User 
        className="w-6 h-6 text-blue-500" 
        ref={userIconRef}
      />
    </nav>
  );
}

🔒 Example 4: File Protection & Team Workflows (Advanced)

Protect critical files and manage team workflows:

# Lock critical brand assets
svger-cli lock ./icons/logo.svg
svger-cli lock ./icons/brand-mark.svg

# Build process automatically skips locked files
svger-cli build ./icons ./components
# ⚠️  Warning: Skipped locked file: logo.svg
# ⚠️  Warning: Skipped locked file: brand-mark.svg
# ✅ Generated 23 components (2 files locked)

# Watch mode respects locks
svger-cli watch ./icons ./components
# File changes to locked files are ignored

# Team workflow: selective unlocking
svger-cli unlock ./icons/logo.svg --confirm
svger-cli build ./icons ./components --force-locked-update

# List all locked files
svger-cli status --locked

Team Configuration (.svgerconfig.json):

{
  "source": "./src/assets/icons",
  "output": "./src/components/icons",
  "framework": "react",
  "typescript": true,
  "forwardRef": true,
  "lockedFiles": [
    "./src/assets/icons/logo.svg",
    "./src/assets/icons/brand-mark.svg"
  ],
  "teamSettings": {
    "requireConfirmation": true,
    "lockByDefault": false,
    "autoLockPatterns": ["**/brand-*", "**/logo-*"]
  }
}

⚡ Example 5: Performance Optimization (Expert)

Maximum performance setup for large-scale projects:

# Performance analysis
svger-cli performance --analyze
# 📊 Processing 1,247 SVG files
# 📊 Average file size: 3.2KB
# 📊 Estimated processing time: 2.1s
# 💡 Recommendations:
#    - Increase batch size to 25
#    - Enable caching for 40% improvement
#    - Use parallel processing

# Apply performance optimizations
svger-cli build \
  --src ./massive-icon-library \
  --out ./optimized-components \
  --framework react \
  --parallel \
  --batch-size 25 \
  --max-concurrency 8 \
  --cache \
  --performance \
  --memory-limit 512

# Monitor performance in real-time
svger-cli performance --monitor &
svger-cli watch ./icons ./components

# Advanced caching strategy
svger-cli config set cache.strategy "aggressive"
svger-cli config set cache.ttl 3600000  # 1 hour
svger-cli config set cache.maxSize 1024  # 1GB

# Benchmark against previous versions
svger-cli performance --benchmark --compare-with v1.5.0

Performance Configuration:

{
  "performance": {
    "optimization": "maximum",
    "parallel": true,
    "batchSize": 25,
    "maxConcurrency": 8,
    "cache": {
      "enabled": true,
      "strategy": "aggressive",
      "ttl": 3600000,
      "maxSize": 1024
    },
    "memory": {
      "limit": 512,
      "gcInterval": 30000,
      "heapWarning": 400
    }
  }
}

Enterprise Usage Patterns:

// Large-scale import pattern
import IconLibrary from './components/icons';

// Lazy loading for performance
const LazyIcon = React.lazy(() => import('./components/icons/SpecificIcon'));

// Tree-shaking friendly imports
import { 
  ArrowLeft,
  ArrowRight,
  Home,
  User,
  Settings 
} from './components/icons';

// Dynamic icon loading
const DynamicIcon = ({ name, ...props }) => {
  const IconComponent = IconLibrary[name];
  return IconComponent ? <IconComponent {...props} /> : null;
};

🎨 Advanced Styling & Theming

Responsive Design System

SVGER-CLI includes a comprehensive responsive design system:

# Enable responsive design
svger-cli build --responsive --src ./icons --out ./components

Configuration:

{
  "responsive": {
    "breakpoints": ["sm", "md", "lg", "xl"],
    "values": {
      "width": ["16px", "20px", "24px", "32px"],
      "height": ["16px", "20px", "24px", "32px"],
      "strokeWidth": ["1", "1.5", "2", "2.5"]
    }
  }
}

Generated React Component:

interface ResponsiveIconProps extends React.SVGProps<SVGSVGElement> {
  size?: 'sm' | 'md' | 'lg' | 'xl';
}

const ResponsiveIcon: React.FC<ResponsiveIconProps> = ({ size = 'md', ...props }) => {
  const sizeMap = {
    sm: { width: 16, height: 16 },
    md: { width: 20, height: 20 },
    lg: { width: 24, height: 24 },
    xl: { width: 32, height: 32 }
  };
  
  return <svg {...sizeMap[size]} {...props}>...</svg>;
};

Theme System

Built-in dark/light theme support with CSS variables:

# Generate with theme support
svger-cli build --theme dark --src ./icons --out ./components

Theme Configuration:

{
  "theme": {
    "mode": "dark",
    "variables": {
      "primary": "#ffffff",
      "secondary": "#94a3b8",
      "accent": "#3b82f6"
    }
  }
}

Generated CSS Variables:

:root {
  --icon-primary: #ffffff;
  --icon-secondary: #94a3b8;
  --icon-accent: #3b82f6;
}

.icon {
  fill: var(--icon-primary);
  stroke: var(--icon-secondary);
}

Animation System

Built-in animation utilities:

# Generate with animations
svger-cli build --animations hover,focus --src ./icons --out ./components

Available Animations:

• hover - Hover state transitions
• focus - Focus state transitions
• spin - Continuous rotation
• pulse - Pulsing opacity
• bounce - Bouncing effect
• scale - Scale on interaction
