Class InMemoryStore<T>

In-memory implementation of the BaseStore using a dictionary. Used for storing key-value pairs in memory.

Example

const store = new InMemoryStore<BaseMessage>();
await store.mset(
  Array.from({ length: 5 }).map((_, index) => [
    `message:id:${index}`,
    index % 2 === 0
      ? new AIMessage("ai stuff...")
      : new HumanMessage("human stuff..."),
  ]),
);

const retrievedMessages = await store.mget(["message:id:0", "message:id:1"]);
await store.mdelete(await store.yieldKeys("message:id:").toArray());
