Multi-Phase Progressive Optimization (MPPO) plugin for NEWK - achieving 40-60% bundle size reduction through intelligent code elimination.

## Features

- 🚀 **10 Optimization Phases**: BAP, TAP, BOP, DGP, DOP, EHP, BRP, DCE, ZRSA, ZULU
- 📉 **40-60% Bundle Reduction**: Real-world results on production applications
- 🔍 **Zero-Risk Safety Assurance**: Browser-based validation ensures no functionality breaks
- ⚡ **Rollup-Powered**: Fast, efficient bundling with modern optimization techniques
- 🎯 **Framework Agnostic**: Works with React, Vue, Angular, and vanilla JavaScript
- 🏗️ **Event-Driven DDD Architecture**: Enterprise-grade design with CQRS patterns

## Installation

```bash
npm install @listenrightmeeow/newk-plugin-mppo
```

Or install with the CLI:

```bash
npm install -g @listenrightmeeow/newk-cli
newk setup plugins
```

## Usage

### CLI Usage

```bash
# Run optimization with MPPO
newk optimize --plugins bundle-optimization

# Skip specific phases
newk optimize --skip-phases ZRSA

# Custom configuration
newk optimize --config .newkrc.production.json
```

### Programmatic Usage

```javascript
import { MPPOPlugin } from '@listenrightmeeow/newk-plugin-mppo';
import { EventBus } from '@listenrightmeeow/newk-core';

// Initialize plugin
const mppo = new MPPOPlugin({
  projectPath: process.cwd(),
  outputPath: 'dist/optimized',
  skipPhases: [] // Run all phases
});

// Set up event listeners
const eventBus = EventBus.getInstance();

eventBus.on('mppo.phase.completed', (event) => {
  console.log(`Phase ${event.phase} completed:`);
  console.log(`  Duration: ${event.duration}ms`);
  console.log(`  Reduction: ${event.metrics.reduction}%`);
});

// Run optimization
const result = await mppo.optimize({
  projectPath: process.cwd(),
  stagingPath: '.newk/staging',
  validateInBrowser: true
});

console.log('Optimization complete!');
console.log(`Total reduction: ${result.metrics.bundleReduction}%`);
console.log(`Original size: ${result.metrics.originalSize}`);
console.log(`Optimized size: ${result.metrics.optimizedSize}`);
```

## Configuration

Add to your `.newkrc.json`:

```json
{
  "plugins": {
    "mppo": {
      "enabled": true,
      "phases": {
        "BAP": { "enabled": true },
        "TAP": { "enabled": true },
        "BOP": { "enabled": true },
        "DGP": { "enabled": true },
        "DOP": { "enabled": true },
        "EHP": { "enabled": true },
        "BRP": { "enabled": true },
        "DCE": { "enabled": true },
        "ZRSA": {
          "enabled": true,
          "browser": {
            "headless": true,
            "timeout": 30000
          }
        },
        "ZULU": { "enabled": true }
      },
      "rollup": {
        "treeshake": true,
        "minify": true,
        "sourcemap": false
      },
      "validation": {
        "browser": true,
        "timeout": 30000,
        "retries": 3
      }
    }
  }
}
```

## Optimization Phases

### 1. BAP (Build Analysis Phase)
Analyzes project structure, identifies entry points, and detects build tool configuration.

### 2. TAP (Tree Analysis Phase)
Performs deep AST analysis to understand code structure and identify optimization opportunities.

### 3. BOP (Build Optimization Phase)
Optimizes build configuration for maximum tree-shaking and dead code elimination.

### 4. DGP (Dependency Graph Phase)
Constructs comprehensive dependency graph to understand module relationships.

### 5. DOP (Dead-code Optimization Phase)
Identifies unused code paths, unreachable functions, and dead exports.

### 6. EHP (Execution Hot Path)
Analyzes runtime execution patterns to preserve critical code paths.

### 7. BRP (Bundle Reduction Phase)
Classifies and reduces bundles through intelligent code splitting.

### 8. DCE (Dead Code Elimination)
Removes identified dead code while preserving functionality.

### 9. ZRSA (Zero-Risk Safety Assurance)
Validates optimized bundles in real browser environment.

### 10. ZULU (Final Processing)
Applies final compression and generates production bundles.

## Event System

MPPO emits detailed events throughout the optimization process:

```javascript
// Phase lifecycle events
eventBus.on('mppo.phase.started', (event) => {
  console.log(`Starting ${event.phase}`);
});

eventBus.on('mppo.phase.completed', (event) => {
  console.log(`Completed ${event.phase}: ${event.metrics.reduction}% reduction`);
});

// Optimization events
eventBus.on('mppo.optimization.started', (event) => {
  console.log(`Optimization started: ${event.sessionId}`);
});

eventBus.on('mppo.optimization.completed', (event) => {
  console.log(`Final metrics:`, event.metrics);
});

// Validation events
eventBus.on('mppo.validation.started', (event) => {
  console.log('Starting browser validation...');
});

eventBus.on('mppo.validation.completed', (event) => {
  console.log(`Validation ${event.success ? 'passed' : 'failed'}`);
});
```

## Performance Results

Real-world optimization results:

| Project Type | Original | Optimized | Reduction | Time |
|-------------|----------|-----------|-----------|------|
| React SPA | 1.2 MB | 540 KB | 55% | 45s |
| Vue.js App | 890 KB | 445 KB | 50% | 38s |
| Next.js | 1.5 MB | 750 KB | 50% | 52s |
| Angular | 1.8 MB | 900 KB | 50% | 58s |
| Vanilla JS | 509 KB | 250 KB | 50.9% | 25s |

## Advanced Usage

### Custom Phase Configuration

```javascript
const mppo = new MPPOPlugin({
  projectPath: process.cwd(),
  phases: {
    TAP: {
      maxDepth: 10,
      analyzeComments: true
    },
    BRP: {
      chunkSizeLimit: 100000,
      vendorSplit: true
    },
    ZRSA: {
      browser: {
        headless: false, // Show browser for debugging
        devtools: true
      }
    }
  }
});
```

### Skipping Phases

```javascript
const mppo = new MPPOPlugin({
  skipPhases: ['ZRSA'], // Skip browser validation
  projectPath: process.cwd()
});
```

### Custom Event Handlers

```javascript
class CustomHandler {
  handlePhaseCompleted(event) {
    // Custom logic for phase completion
    if (event.phase === 'DCE' && event.metrics.reduction < 30) {
      console.warn('Low reduction achieved, consider reviewing configuration');
    }
  }
}

const handler = new CustomHandler();
eventBus.on('mppo.phase.completed', handler.handlePhaseCompleted.bind(handler));
```

## Troubleshooting

### Browser Validation Fails

If ZRSA phase fails:

```bash
# Skip browser validation temporarily
newk optimize --skip-phases ZRSA

# Or increase timeout
newk optimize --validation-timeout 60000
```

### Low Reduction Rates

Check your configuration:

```javascript
// Enable aggressive optimization
{
  "plugins": {
    "mppo": {
      "rollup": {
        "treeshake": {
          "moduleSideEffects": false,
          "propertyReadSideEffects": false
        }
      }
    }
  }
}
```

### Memory Issues

For large projects:

```bash
# Increase Node.js memory limit
NODE_OPTIONS="--max-old-space-size=8192" newk optimize
```
