Class XataChatMessageHistory<XataClient>

A class for managing chat message history using Xata.io client. It extends the BaseListChatMessageHistory class and provides methods to get, add, and clear messages. It also ensures the existence of a table where the chat messages are stored.

Example

const chatHistory = new XataChatMessageHistory({
  table: "messages",
  sessionId: new Date().toISOString(),
  client: new BaseClient({
    databaseURL: process.env.XATA_DB_URL,
    apiKey: process.env.XATA_API_KEY,
    branch: "main",
  }),
  apiKey: process.env.XATA_API_KEY,
});

const chain = new ConversationChain({
  llm: new ChatOpenAI(),
  memory: new BufferMemory({ chatHistory }),
});

const response = await chain.invoke({
  input: "What did I just say my name was?",
});
console.log({ response });
