✅ Zero Breaking Changes - All your existing code works
✅ Automatic Config Migration - Your .svgconfig.json updates automatically
✅ 50% Faster - Performance optimizations throughout
✅ Plugin System - Extend with custom plugins
Upgrade Now:
npm install -g svger-cli@4.0.5
# or
npm install --save-dev svger-cli@4.0.5
See What's New → | Migration Guide →
v4.0.5 introduces critical performance optimizations and stability fixes:
v4.0.5 introduces a powerful plugin architecture that allows you to extend and customize SVG processing:
# Use built-in plugins
svger --src ./svgs --out ./components --plugin optimize --plugin color-theme
svger --src ./svgs --out ./components --plugins optimize,color-theme,minify
# List all available plugins
svger --list-plugins
Built-in Plugins:
Plugin Features:
// Programmatic API with plugins
import { svgProcessor } from 'svger-cli';
const result = await svgProcessor.processWithPlugins(svgContent, {
plugins: ['optimize', 'minify'],
config: {
// Plugin-specific configuration
}
});

For questions, issues, or contributions, reach out to:
First-class support for all major build tools with zero configuration:
// One-line setup for any build tool
const { SvgerWebpackPlugin } = require('svger-cli/webpack');
import { svgerVitePlugin } from 'svger-cli/vite';
import { svgerRollupPlugin } from 'svger-cli/rollup';
const { svgerBabelPlugin } = require('svger-cli/babel');
const { withSvger } = require('svger-cli/nextjs');
Automatically generates clean index.ts files with a single, consistent export pattern that avoids naming conflicts:
// Auto-generated in your output directory
// Re-exports with renamed defaults for tree-shaking
export { default as ArrowLeft } from './ArrowLeft';
export { default as ArrowRight } from './ArrowRight';
export { default as HomeIcon } from './HomeIcon';
export { default as UserProfile } from './UserProfile';
/**
* SVG Components Index
* Generated by svger-cli
*
* Import individual components:
* import { ArrowLeft } from './components';
*
* Import all components:
* import * as Icons from './components';
*/
Import flexibility:
// Named imports (recommended - tree-shaking friendly)
import { ArrowLeft, ArrowRight, HomeIcon } from './components';
// Namespace import (for accessing all icons)
import * as Icons from './components';
const ArrowIcon = Icons.ArrowLeft;
// Individual file imports (when you need just one component)
import ArrowLeft from './components/ArrowLeft';
Components now support comprehensive prop interfaces with React.forwardRef:
<Icon className="custom-class" style={{ color: 'red' }} size={32} />
Lock files to prevent accidental modifications during builds:
svger-cli lock ./icons/critical-logo.svg # Protects during all operations
Industry-leading 6-phase optimization pipeline with pixel-perfect visual validation:
# Optimize SVG files with configurable levels
svger-cli optimize input.svg --level maximum # 57.77% reduction
svger-cli optimize icons/ --level balanced # 43.33% reduction (recommended)
# Test optimizations for visual regressions
node test-visual-diff.js # Unit tests (8/8 passing ✅)
node test-visual-integration.js # Integration tests (16/16 passing, 100% ✅)
Results: Up to 57.77% file size reduction at MAXIMUM level, competitive with SVGO. Visual diff testing ensures <1% pixel difference on geometric shapes, guaranteeing production-quality output with zero visual regressions.
📊 Visual Quality Metrics:
- Geometric shapes: 0.0002% visual difference (pixel-perfect)
- Circles/curves: 2.4% difference (anti-aliasing acceptable)
- Complex paths: 14.3% difference (path simplification, visually acceptable)
- Text rendering: 0.95% difference (font rendering variations)

# ⚠️ Warning: Skipped locked file: logo.svg
# ⚠️ Warning: Skipped locked file: brand-mark.svg
# ✅ Generated 23 components (2 files locked)
# Watch mode respects locks

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;
};
SVGER-CLI includes a comprehensive responsive design system:
# Enable responsive design
svger-cli build --responsive --src ./icons --out ./components

"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>
);
};
Built-in dark/light theme support with CSS variables:
# Generate with theme support
svger-cli build --theme dark --src ./icons --out ./components

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

SVGER-CLI v4.0.5 includes visual diff testing to guarantee pixel-perfect optimization quality:
| Optimization Level | Size Reduction | Processing Time | Visual Quality | Memory Usage |
|---|---|---|---|---|
| BASIC | 16.88% | 0.32ms | Pixel-perfect ✅ | 55.65KB |
| BALANCED | 18.38% | 1.15ms | Pixel-perfect ✅ | 158.38KB |
| AGGRESSIVE | 21.60% | 1.97ms | Pixel-perfect ✅ | 225.46KB |
| MAXIMUM | 26.49% | 3.11ms | Pixel-perfect ✅ | 225.49KB |

Visual Quality Metrics:
SVGER-CLI includes a powerful multi-phase optimization engine with configurable levels:
| Level | Reduction | Speed | Use Case | Stages Enabled |
|---|---|---|---|---|
| BASIC | 16.88% | Fastest | Quick cleaning | Comments, whitespace, metadata |
| BALANCED | 18.38% | Fast | Recommended | + Numeric precision, style optimization |
| AGGRESSIVE | 21.60% | Medium | Production builds | + Path optimization, transform collapsing |
| MAXIMUM | 57.77% | Slower | Icon libraries | + Path simplification, deduplication |
Example Results:
# Original SVG: 824 bytes
svger-cli optimize input.svg --level basic # → 530 bytes (35.68%)
svger-cli optimize input.svg --level balanced # → 467 bytes (43.33%)
svger-cli optimize input.svg --level aggressive # → 421 bytes (48.91%)
svger-cli optimize input.svg --level maximum # → 348 bytes (57.77%)

The test script processes 606 real SVG icons across multiple frameworks (React, Vue, Angular) and provides detailed metrics including processing time, memory usage, and throughput.
Generated components include comprehensive testing utilities:
// Generated React component test
import { render, screen } from '@testing-library/react';
import { IconName } from './IconName';
describe('IconName', () => {
it('renders with default props', () => {
render(<IconName />);
const svg = screen.getByRole('img', { hidden: true });
expect(svg).toBeInTheDocument();
});
it('accepts custom props', () => {
render(<IconName width={32} height={32} fill="red" />);
const svg = screen.getByRole('img', { hidden: true });

Good News: v4.0.5 includes automatic configuration migration! Your existing config will be upgraded seamlessly on first run.
When you run any svger command with a v3.x config:
svger build --src ./svgs --out ./components
The tool will:
version: "4.0.5" fieldplugin (singular) → plugins (array)Example Migration:
// Your existing v3.x config (.svgconfig.json)
{
"source": "./src/assets/svg",
"output": "./src/components/icons",
"framework": "react",
"plugin": { "name": "optimize" },
"performance": { "optimization": "basic" }
}
// Automatically becomes v4.0.5:
{
"version": "4.0.5",
"source": "./src/assets/svg",
"output": "./src/components/icons",
"framework": "react",
"plugins": [{ "name": "optimize" }],
"performance": { "optimization": "fast" }
}
| v3.x | v4.0.5 | Description |
