import { Mastra } from "@mastra/core";
import { Memory } from "@mastra/memory";
import { LibSQLStore } from "@mastra/libsql";

const conversationMemory = new Memory({
  storage: new LibSQLStore({ id: 'conversation-store', url: ":memory:" }),
});

const mastra = new Mastra({
  memory: {
    conversationMemory,
  },
});

// Later, retrieve the memory instance
const memory = mastra.getMemory("conversationMemory");
