@chat-adapter/state-memory
In-memory state adapter for Chat SDK. For development and testing only — state is lost on restart.
Warning: Only use the memory adapter for local development and testing. State is lost on restart and locks don't work across multiple instances. For production, use @chat-adapter/state-redis, @chat-adapter/state-ioredis, or @chat-adapter/state-pg.
Installation
pnpm add @chat-adapter/state-memory
Usage
import { Chat } from "chat";
import { createMemoryState } from "@chat-adapter/state-memory";
const bot = new Chat({
userName: "mybot",
adapters: { /* ... */ },
state: createMemoryState(),
});
No configuration options are needed.
