🚀 jatin-lean v1.0.0 - Universal System Optimization Platform

Enterprise-grade optimization platform with native Node.js bindings and professional CLI. Reduce disk footprint by up to 50% while leveraging hardware-level optimizations (io_uring, SIMD, eBPF) for unmatched performance.

🎯 What's New in v1.0.0

🔥 Native N-API Bindings

• Direct Rust ↔ JavaScript integration - No process spawning overhead
• 10-100x faster than CLI wrapper approach
• True async/await with native promises
• Zero-copy data transfer between Rust and Node.js
• Full TypeScript support with complete type definitions

🎨 Professional CLI Interface

• 41 commands organized into 6 categories
• Hierarchical structure - jatin-lean <category> <command>
• JSON output support for all commands
• Comprehensive help system with examples

📥 Installation

npm install -g jatin-lean

Requirements:

• Node.js >= 14
• Rust toolchain (for building native bindings)

🚀 Quick Start

As a Node.js Library (NEW!)

const lean = require('jatin-lean');

async function optimize() {
  // Scan node_modules
  const scan = await lean.scanNodeModules('.');
  console.log('Potential savings:', scan.savingsPercentage.toFixed(1), '%');
  
  // Check project health
  const health = await lean.checkHealth('.');
  console.log('Health status:', health.overallHealth);
  
  // Assess system performance
  const system = await lean.assessSystem();
  console.log('System score:', system.overallScore);
  
  // Run benchmarks
  const benchmarks = await lean.runBenchmarks();
  benchmarks.forEach(b => {
    console.log(`${b.name}: ${b.opsPerSec.toFixed(0)} ops/sec`);
  });
}

optimize();

As a CLI Tool

# Scan node_modules
jatin-lean node scan

# Run health check

const dedup = await lean.findDuplicates(projectPath);
// Returns: { duplicateGroups, totalDuplicates, wastedSpace, potentialSavings }

// Analyze compression potential
const compressionSavings = await lean.analyzeCompression(projectPath);
// Returns: number (percentage)

// Analyze tree-shaking potential
const treeshakeSavings = await lean.analyzeTreeshake(projectPath);
// Returns: number (percentage)

// Get dependency graph size
const depsCount = await lean.getDependencyGraph(projectPath);
// Returns: number

System Optimization

// Assess system performance
const assessment = await lean.assessSystem();
// Returns: { overallScore, cpuScore, memoryScore, ioScore, recommendations }

// Detect CPU capabilities
const cpuTier = await lean.detectCpuCapabilities();
// Returns: string (e.g., "AVX2 (256-bit)")

// Run benchmarks
const benchmarks = await lean.runBenchmarks();
// Returns: [{ name, meanNs, medianNs, minNs, maxNs, opsPerSec }, ...]

Utility Functions

// Get version
const version = lean.getVersion();
// Returns: string

// Get AI-friendly context
const context = await lean.getAiContext();
// Returns: { tool, version, capabilities, systemInfo }
