Quick Start
npm install supermemory
import Supermemory from 'supermemory';
const client = new Supermemory();
// Store conversation memory
await client.add({
content: 'User prefers functional TypeScript patterns',
containerTag: 'user_123',
});
// Get user profile and relevant memories
const { profile, searchResults } = await client.profile({
containerTag: 'user_123',
q: 'What programming style does the user prefer?',
});
console.log(profile.static); // Long-term facts
console.log(profile.dynamic); // Recent context
