@cognitive-engine/store-memory
In-memory store adapter for cognitive-engine. Ideal for testing, prototyping, and development.
Install
npm install @cognitive-engine/store-memoryUsage
import { MemoryStore } from '@cognitive-engine/store-memory'
const store = new MemoryStore()
// CRUD operations
await store.set('users', 'user-1', { name: 'Alice', role: 'engineer' })
const user = await store.get('users', 'user-1')
await store.delete('users', 'user-1')
// Query
const results = await store.find('users', { role: 'engineer' })
// Upsert
await store.upsert('users', 'user-1', { name: 'Alice', role: 'senior engineer' })
// Vector search (brute-force cosine similarity)
await store.set('documents', 'doc-1', { text: 'Hello', embedding: [0.1, 0.2, 0.3] })
await store.set('documents', 'doc-2', { text: 'World', embedding: [0.4, 0.5, 0.6] })
const similar = await store.vectorSearch('documents', [0.1, 0.2, 0.3], { limit: 5 })When to Use

Data lives only in process memory — it's lost on restart. For persistence, implement the Store interface from @cognitive-engine/core for your database of choice.
