# YOGIWAY & PATHX - Ultra-Efficient Data Formats for AI & Storage

**YOGIWAY** (Your Optimal Gateway Interface - Way) is an ultra-compact, nested-aware data format designed for LLM prompts. **PATHX** is a binary format optimized for storage and transmission with maximum performance.

## 🚀 Quick Start

### Option 1: VS Code Extension (Easiest! ⭐)

**One-click compression for Cursor, Windsurf, VS Code, and all AI assistants!**

```bash
cd vscode-extension
./install.sh
```

Then:
1. Select code in any file
2. Press `Cmd+Shift+Y` (Mac) or `Ctrl+Shift+Y` (Windows)
3. Paste in AI chat - Done! 🎉

**That's it!** The extension automatically compresses and copies to clipboard.

### Option 2: Use as Library (FREE & OPEN SOURCE)

**🎉 100% FREE - No license required!**

**📦 Note:** The library is available via npm - completely free and open source!

```bash
npm install @yogesh0333/yogiway
```

```typescript
import { encode, decode, pathxEncode, pathxDecode } from '@yogesh0333/yogiway';

// Use immediately - completely free!
const data = { users: [{ id: 1, name: 'Alice' }] };
const compressed = encode(data); // ✅ Works immediately - no license needed!

// YOGIWAY - for LLM prompts (text-based)
const yogiway = encode(data, { usePathReferences: true });
const decoded = decode(yogiway);

// PATHX - for storage/transmission (binary)
const pathx = pathxEncode(data, { typedArrays: true, checksum: true });
const decoded2 = pathxDecode(pathx);
```

**📚 Installation:** `npm install @yogesh0333/yogiway` - Completely free and open source!

## 💰 Real-World Cost Savings

### Example: AI API Usage (10,000 requests/day)

**With JSON:**
- Input tokens: 2,000 × 10,000 = 20M tokens/day
- Cost: **$200/day = $6,000/month**

**With YOGIWAY (40% reduction):**
- Input tokens: 1,200 × 10,000 = 12M tokens/day
- Cost: **$120/day = $3,600/month**

**💰 Savings: $2,400/month = $28,800/year**

**ROI**: 1 day implementation = $28,800/year savings = **7,200% ROI**

### Example: E-commerce Chatbot (50,000 conversations/day)

**With JSON:**
- 25M tokens/day = **$250/day = $7,500/month**

**With YOGIWAY (45% reduction):**
- 13.75M tokens/day = **$137.50/day = $4,125/month**

**💰 Savings: $3,375/month = $40,500/year**

### Example: Developer Team (10 developers, 1,000 requests/day each)

**With JSON:**
- 1.5M tokens/day per developer = **$15/day = $450/month per developer**
- Team total: **$4,500/month**

**With YOGIWAY (40% reduction):**
- 0.9M tokens/day per developer = **$9/day = $270/month per developer**
- Team total: **$2,700/month**

**💰 Savings: $1,800/month = $21,600/year**

## 🎯 When to Use What

### Use **YOGIWAY** (Text Format) When:
- ✅ **Sending data to LLMs** (GPT, Claude, etc.)
- ✅ **Human-readable format needed** (debugging, inspection)
- ✅ **Token efficiency is priority** (reducing API costs)
- ✅ **Moderate nesting** (5-15 levels)
- ✅ **Self-documenting format** (path mapping visible)
- ✅ **Simple integration** (text-based, no binary handling)

### Use **PATHX** (Binary Format) When:
- ✅ **Database storage** (compact, fast)
- ✅ **API transmission** (bandwidth optimization)
- ✅ **Maximum performance** (fastest encoding/decoding)
- ✅ **Deep nesting** (15+ levels)
- ✅ **Large datasets** (GB/TB scale)
- ✅ **Path-heavy data** (many repeated paths)

## 📊 Format Comparison

| Format | Type | Best For | Deep Nesting | Token Efficiency | Speed |
|--------|------|----------|-------------|------------------|-------|
| **YOGIWAY** | Text | LLM prompts | ✅ Excellent | ✅✅ Excellent | Fast |
| **PATHX** | Binary | Storage/transmission | ✅✅ Excellent | ✅✅✅ Best | ✅✅ Fastest |
| **TOON** | Text | Simple cases | ⚠️ Limited | ✅ Good | Fast |
| **JSON** | Text | General purpose | ✅ Excellent | ⚠️ Verbose | Fast |

## 🛠️ Real-World Usage Examples

### Example 1: AI Coding Assistant (Cursor/Windsurf)

**Problem**: Sending large codebases to AI models is expensive.

```typescript
import { encode } from '@yogesh0333/yogiway';

// Before: JSON (50KB = 12,500 tokens = $0.125 per request)
const projectStructure = {
  files: [
    { path: 'src/components/Button.tsx', code: '...', imports: [...] },
    // ... 100 more files
  ]
};

// After: YOGIWAY (30KB = 7,500 tokens = $0.075 per request)
const compressed = encode(projectStructure, { 
  usePathReferences: true,
  mode: 'minimal' 
});

// 💰 Savings: $0.05 per request = $50/day for 1,000 requests
```

### Example 2: E-commerce Product Catalog

**Problem**: Store millions of products with nested attributes.

```typescript
import { pathxEncode, pathxDecode } from '@yogesh0333/yogiway';

const product = {
  id: 12345,
  name: 'Laptop',
  specs: {
    cpu: { brand: 'Intel', model: 'i7-12700K' },
    ram: { size: 16, type: 'DDR4' },
    storage: { type: 'SSD', capacity: 512 }
  },
  pricing: {
    base: 999.99,
    discounts: [{ type: 'student', amount: 100 }]
  }
};

// Store in database as PATHX (compact, fast)
const binary = pathxEncode(product, { 
  typedArrays: true,
  checksum: true 
});

// Later: Decode for LLM prompt
const decoded = pathxDecode(binary);
const yogiway = encode(decoded, { usePathReferences: true });
// Send to LLM...
```

### Example 3: User Profile Storage

**Problem**: Store deeply nested user profiles efficiently.

```typescript
import { pathxEncode, pathxDecode, pathxToDebugString } from '@yogesh0333/yogiway';

const userProfile = {
  profile: {
    personal: {
      name: 'John Doe',
      address: {
        street: '123 Main St',
        city: 'New York',
        zip: '10001'
      }
    },
    preferences: {
      theme: 'dark',
      notifications: { email: true, push: false }
    }
  }
};

// Store as PATHX (compact)
const stored = pathxEncode(userProfile, { optimizePaths: true });

// Debug: Human-readable format (no performance impact)
const debug = pathxToDebugString(stored);
console.log(debug); // Pretty JSON output

// Decode when needed
const decoded = pathxDecode(stored);
```

### Example 4: API Response Optimization

**Problem**: Reduce API response size and bandwidth costs.

```typescript
import { pathxEncode, pathxDecode } from '@yogesh0333/yogiway';

// API endpoint
app.get('/api/users', async (req, res) => {
  const users = await db.getUsers(); // Large nested data
  
  // Option 1: PATHX for binary response
  const binary = pathxEncode(users, { 
    typedArrays: true,
    compress: true 
  });
  res.setHeader('Content-Type', 'application/octet-stream');
  res.send(binary);
  
  // Option 2: YOGIWAY for text response (if client needs readable)
  const yogiway = encode(users, { usePathReferences: true });
  res.json({ format: 'yogiway', data: yogiway });
});

// Client side
const response = await fetch('/api/users');
const binary = await response.arrayBuffer();
const users = pathxDecode(new Uint8Array(binary));
```

### Example 5: LLM Context Compression

**Problem**: Send large context to LLM without exceeding token limits.

```typescript
import { encode, smartEncode } from '@yogesh0333/yogiway';

const context = {
  conversation: [
    { role: 'user', content: '...' },
    { role: 'assistant', content: '...' }
  ],
  userProfile: { /* large nested object */ },
  documents: [ /* array of documents */ ]
};

// Smart encoding: automatically chooses best format
const forLLM = smartEncode(context, 'llm'); // Returns YOGIWAY
const forStorage = smartEncode(context, 'storage'); // Returns PATHX

// Manual: Maximum compression for LLM
const compressed = encode(context, {
  mode: 'minimal',
  usePathReferences: true,
  compressPaths: true,
  adaptiveFlattening: true
});

// Send to LLM (40-50% fewer tokens)
await openai.chat.completions.create({
  messages: [{ role: 'system', content: compressed }]
});
```

## 🔧 Advanced Features

### YOGIWAY Encoding Modes

```typescript
import { encode } from '@yogesh0333/yogiway';

// Performance mode (default, fastest)
const fast = encode(data, { mode: 'performance' });

// Minimal mode (smallest size, maximum compression)
const small = encode(data, { mode: 'minimal' });

// Compatibility mode (JSON-like, maximum compatibility)
const compatible = encode(data, { mode: 'compatibility' });
```

### PATHX Optimizations

```typescript
import { pathxEncode, pathxDecode, pathxToDebugString } from '@yogesh0333/yogiway';

// With typed arrays (2-3x faster for numeric arrays)
const binary = pathxEncode(data, { 
  typedArrays: true,      // Auto-detect homogeneous arrays
  checksum: true,        // Data integrity verification
  optimizePaths: true,   // Path caching
  streaming: true        // For large datasets
});

// Human-readable debug (no performance impact)
const debug = pathxToDebugString(binary);
console.log(debug); // JSON-formatted output

// Validate data integrity
import { validatePathx } from '@yogesh0333/yogiway';
const isValid = validatePathx(binary);
```

### Format Converters

```typescript
import { 
  yogiwayToPathx, 
  pathxToYogiway, 
  smartEncode 
} from '@yogesh0333/yogiway';

// Store as PATHX, send to LLM as YOGIWAY
const stored = pathxEncode(data, { optimizePaths: true });
const forLLM = pathxToYogiway(stored, { usePathReferences: true });

// Smart encoding: auto-choose format
const llmFormat = smartEncode(data, 'llm');        // YOGIWAY
const storageFormat = smartEncode(data, 'storage'); // PATHX
```
