# Installation

## Requirements

- **Node.js 22+** or **Bun 1.0+**
- TypeScript is optional — Brainy ships with full type definitions

## Install

```bash
npm install @soulcraft/brainy
```

Or with your preferred package manager:

```bash
bun add @soulcraft/brainy
yarn add @soulcraft/brainy
pnpm add @soulcraft/brainy
```

## Verify

```typescript
import { Brainy } from '@soulcraft/brainy'

const brain = new Brainy()
await brain.init()

console.log('Brainy ready.')
```

## Native Acceleration (Optional)

For production workloads, add Cor for Rust-accelerated SIMD distance calculations and native embeddings:

```bash
npm install @soulcraft/cor
```

```typescript
import { Brainy } from '@soulcraft/brainy'

const brain = new Brainy({ plugins: ['@soulcraft/cor'] })
await brain.init()  // native providers registered during init
```

Cor registers native (Rust/SIMD) vector, metadata, and graph engines behind the same Brainy `find()` API — no code changes, an optional dependency for production-scale workloads.

## Server-only since 8.0

Brainy 8.0 runs on Node.js 22+ and Bun 1.0+. Browser support (OPFS storage,
Web Workers, in-browser WASM embeddings) was removed in 8.0 — the 7.x line
remains available on npm if you need it.

## TypeScript

Brainy ships with full TypeScript types. No `@types/` package needed:

```typescript
import { Brainy, NounType, VerbType } from '@soulcraft/brainy'

const brain = new Brainy()
await brain.init()

const id = await brain.add({
  data: 'Hello, Brainy',
  type: NounType.Concept,
  metadata: { created: Date.now() }
})
```
