@anvia/memory-sqlite: Examples

Basic memory store

import { createSqliteMemoryStore } from "@anvia/memory-sqlite";

export const memory = createSqliteMemoryStore({
  path: "data/anvia-memory.sqlite",
});

Test memory

const memory = createSqliteMemoryStore();

The default path is :memory:, so each store instance uses an in-memory SQLite database.

Scoped agent

const agent = new AgentBuilder("support", model)
  .memory(
    createSqliteMemoryStore({
      path: "data/anvia-memory.sqlite",
      scope: { metadataKeys: ["tenantId"] },
    }),
    { savePolicy: "turn" },
  )
  .build();

Load initial messages

export async function loadThread(input: LoadThreadInput) {
  const agent = createSupportAgent({
    model: input.model,
    tools: input.tools,
  });

  const messages = await agent
    .session(input.conversationId, {
      userId: input.user.id,
      metadata: { tenantId: input.user.tenantId },
    })
    .messages();

  return { messages };
}

import type { Message } from "@anvia/core";
import { initialMessagesFromMemory, useChat } from "@anvia/react";

export function ThreadPage({
  conversationId,
  messages,
}: {
  conversationId: string;
  messages: Message[];
}) {
  const chat = useChat({
    endpoint: `/api/conversations/${conversationId}/chat`,
    initialMessages: initialMessagesFromMemory(messages),
  });

  return <ChatProvider controller={chat}>{/* thread */}</ChatProvider>;
}
