IPFS Datastore Chat Memory

For a storage backend you can use the IPFS Datastore Chat Memory to wrap an IPFS Datastore allowing you to use any IPFS compatible datastore.

Setup

First, install the integration dependencies:

See this section for general instructions on installing LangChain packages.

npm

npm install cborg interface-datastore it-all @langchain/community @langchain/core

Now you can install and use an IPFS Datastore of your choice. Here are some options:

• datastore-core Datastore in-memory implementation.
• datastore-fs Datastore implementation with file system backend.
• datastore-idb Datastore implementation with IndexedDB backend.
• datastore-level Datastore implementation with level(up|down) backend
• datastore-s3 Datastore implementation backed by s3.

Usage

// Replace FsDatastore with the IPFS Datastore of your choice.
import { FsDatastore } from "datastore-fs";
import { IPFSDatastoreChatMessageHistory } from "@langchain/community/stores/message/ipfs_datastore";

const datastore = new FsDatastore("path/to/store");
const sessionId = "my-session";

const history = new IPFSDatastoreChatMessageHistory({ datastore, sessionId });
