Function langgraphMemory

langgraphMemory(
    mm: MemoryManager,
    ref: ConversationRef,
): {
    loadMemories: (
        query: string,
        tokenBudget?: number,
    ) => Promise<LangGraphSystemMessage | null>;
    saveTurn: (
        userMessage: string,
        assistantMessage: string,
    ) => Promise<string>;
}
LangGraph.js: memory for a graph whose state carries a messages array (e.g. MessagesState). loadMemories returns a system message to MERGE into the graph state before the model node (or null when there is nothing relevant), and saveTurn persists a completed turn, typically wired as a pre-model node + a post-model node. Structural, so @langchain/langgraph stays an optional peer dependency.
Parameters
- mm: MemoryManager
- ref: ConversationRef
Returns {
    loadMemories: (
        query: string,
        tokenBudget?: number,
    ) => Promise<LangGraphSystemMessage | null>;
    saveTurn: (
        userMessage: string,
        assistantMessage: string,
    ) => Promise<string>;
}
