All code examples in installation.md and quick-start.md were tagged as javascript — converted to typescript throughout. quick-start.md also gets explicit type annotations: - reactId/nextId declared as string (return type of brain.add) - results declared as FindResult[] - results[0].data and results[0].score shown in console.log example

# Quick Start
|
|
|
|
Get Brainy running in under a minute.
|
|
|
|
## 1. Install
|
|
|
|
```bash
|
|
npm install @soulcraft/brainy
|
|
```
|
|
|
|
## 2. Initialize
|
|
|
|
```typescript
|
|
import { Brainy, NounType, VerbType } from '@soulcraft/brainy'
|
|
|
|
const brain = new Brainy()
|
|
await brain.init()
|
|
```
|
|
|
|
That's it. Brainy auto-configures storage, loads the embedding model, and builds the indexes.
|
|
|
|
## 3. Add Knowledge
|
|
|
|
```typescript
|
|
// Text is automatically embedded into 384-dim vectors
|
|
const reactId: string = await brain.add({
|
|
data: 'React is a JavaScript library for building user interfaces',
|
|
type: NounType.Concept,
|
|
metadata: { category: 'frontend', year: 2013 }
|
|
})
|
|
|
|
const nextId: string = await brain.add({
|
|
data: 'Next.js framework for React with server-side rendering',
|
|
type: NounType.Concept,
|
|
metadata: { category: 'framework', year: 2016 }
|
|
})
|
|
```
|
|
|
|
## 4. Create Relationships
|
|
|
|
```typescript
|
|
// Typed graph relationships
|
|
await brain.relate({
|
|
from: nextId,
|
|
to: reactId,
|
|
type: VerbType.BuiltOn
|
|
})
|
|
```
|
|
|
|
## 5. Query with Triple Intelligence
|
|
|
|
```typescript
|
|
import type { FindResult } from '@soulcraft/brainy'
|
|
|
|
// All three search paradigms in one call
|
|
const results: FindResult[] = await brain.find({
|
|
query: 'modern frontend frameworks', // Vector similarity search
|
|
where: { year: { greaterThan: 2015 } }, // Metadata filtering
|
|
connected: { to: reactId, depth: 2 } // Graph traversal
|
|
})
|
|
|
|
console.log(results[0].data) // 'Next.js framework for React...'
|
|
console.log(results[0].score) // 0.94
|
|
```
|
|
|
|
## What Just Happened
|
|
|
|
Every entity you `add()` lives in three indexes simultaneously:
|
|
|
|
| Index | What it stores | Query with |
|
|
|-------|---------------|------------|
|
|
| Vector | 384-dim embedding of `data` | `find({ query: '...' })` |
|
|
| Metadata | All `metadata` fields | `find({ where: { ... } })` |
|
|
| Graph | Typed relationships from `relate()` | `find({ connected: { ... } })` |
|
|
|
|
`find()` queries all three in parallel and fuses the results.
|
|
|
|
## Natural Language Queries
|
|
|
|
Brainy understands 220+ natural language patterns:
|
|
|
|
```typescript
|
|
// These all work without any configuration
|
|
await brain.find({ query: 'recent documents about machine learning' })
|
|
await brain.find({ query: 'articles created this week' })
|
|
await brain.find({ query: 'people who work at Anthropic' })
|
|
```
|
|
|
|
## Next Steps

|
|
- [The Find System](/docs/guides/find-system) — advanced queries, operators, and graph traversal
|
|
- [API Reference](/docs/api/reference) — complete method documentation
|
|
