🔌 Brainy 2.0 Augmentations Complete Reference

All 27 augmentations that power Brainy's extensibility - with locations, usage, and examples

Quick Start

import { BrainyData } from '@soulcraft/brainy'

const brain = new BrainyData({
  // Augmentations auto-configure based on environment
  storage: 'auto',     // Storage augmentation
  cache: true,         // Cache augmentation
  index: true          // Index augmentation
})

await brain.init()  // Augmentations initialize automatically

Core Concepts

What are Augmentations?

Augmentations are modular extensions that add functionality to Brainy without cluttering the core API. They follow a unified interface and can be:

• Auto-enabled: Based on configuration (cache, index, storage)
• Manually registered: For custom functionality
• Chained: Multiple augmentations work together seamlessly

Augmentation Lifecycle

1. Registration: Augmentations register before init()
2. Initialization: Two-phase init (storage first, then others)
3. Execution: Hook into operations (before/after/both)
4. Shutdown: Clean teardown on brain.shutdown()

Augmentation Configuration

Auto-Configuration

const brain = new BrainyData({
  // These auto-register augmentations:
  storage: 'auto',        // Storage augmentation
  cache: true,           // Cache augmentation  
  index: true,           // Index augmentation
  wal: true,            // WAL augmentation
  metrics: true         // Metrics augmentation
})

Manual Registration

const brain = new BrainyData()

// Register before init()
const customAug = new MyCustomAugmentation()
await brain.registerAugmentation(customAug)

await brain.init()

Creating Custom Augmentations

import { BaseAugmentation } from '@soulcraft/brainy'

class MyAugmentation extends BaseAugmentation {
  readonly name = 'my-augmentation'
  readonly timing = 'after'  // before | after | both
  readonly operations = ['addNoun', 'search']  // Which ops to hook
  readonly priority = 10      // Execution order (lower = earlier)
  
  protected async onInit(): Promise<void> {
    // Initialize your augmentation
  }
  
  async execute<T>(
    operation: string,
    params: any,
    context?: AugmentationContext
  ): Promise<T | void> {
    // Your augmentation logic
    if (operation === 'addNoun') {
      console.log('Noun added:', params)
    }
  }
  
  protected async onShutdown(): Promise<void> {
    // Cleanup
  }
}

---

Augmentation Timing & Priority

Timing Options

• before: Runs before the operation (can modify params)
• after: Runs after the operation (can see results)
• both: Runs before AND after

Priority (lower = earlier)

1. Storage augmentations (priority: 0)
2. Cache/Index augmentations (priority: 5-10)
3. Monitoring/Metrics (priority: 15-20)
4. Conduits/Synapses (priority: 20-30)

---

Key Integration Points

Where Augmentations Hook In

BrainyData Constructor:

• Storage augmentations register based on config
• Cache/Index augmentations auto-register if enabled

brain.init():

• Two-phase initialization (storage first, then others)
• Augmentations can access brain instance via context

Operations (addNoun, search, etc.):

• Augmentations execute based on timing and operations filter
• Can modify params (before) or see results (after)

brain.shutdown():

• All augmentations cleaned up in reverse order

---

Performance Impact

Most augmentations have minimal overhead:

• Cache: ~1ms per search (saves 10-100ms on hits)
• Index: ~1ms per operation (saves 100ms+ on queries)
• Metrics: <1ms per operation
• Storage: Varies by adapter (memory: 0ms, S3: 50-200ms)

---

Best Practices

1. Let auto-configuration work: Most apps need zero manual config
2. Storage first: Always configure storage before other augmentations
3. Use built-in augmentations: They're optimized and battle-tested
4. Custom augmentations: Extend BaseAugmentation for consistency
5. Respect timing: Use 'before' to modify, 'after' to observe
6. Mind priority: Lower numbers execute first

---

Troubleshooting

Augmentation not working?

// Check if registered
brain.listAugmentations()

// Check if enabled
brain.isAugmentationEnabled('cache')

// Enable/disable at runtime
brain.enableAugmentation('cache')
brain.disableAugmentation('cache')

Performance issues?

// Check augmentation overhead
const stats = brain.getStatistics()
console.log(stats.augmentations)

// Disable non-critical augmentations
brain.disableAugmentation('monitoring')

Augmentations make Brainy infinitely extensible while keeping the core API clean and simple!
