Originally created by @EfosaE on GitHub (Feb 3, 2026).

Checked other resources

  • I added a very descriptive title to this issue.
  • I searched the LangGraph.js documentation with the integrated search.
  • I used the GitHub search to find a similar question and didn't find it.
  • I am sure that this is a bug in LangGraph.js rather than my code.
  • The bug is not resolved by updating to the latest stable version of LangGraph (or the specific integration package).

Example Code

// import { RedisStore } from '@langchain/langgraph-checkpoint-redis/dist/store'; // FIXES TS IMPORT BUT DOESNT RUN
import { RedisStore } from "@langchain/langgraph-checkpoint-redis/store";  // ACTUAL DIRECTIVE FROM LIBRARY README BUT APP DOESNT RUN
// import { RedisStore } from '@langchain/langgraph-checkpoint-redis/dist/store.cjs'; // FIXES TS IMPORT BUT DOESNT RUN

Node.js v22.15.0

Using the actual import directive from the libray ReadME
Cannot find module '@langchain/langgraph-checkpoint-redis/store' or its corresponding type declarations.
There are types at 'c:/Users/Efosa/Desktop/nextgrade-backend/node_modules/@langchain/langgraph-checkpoint-redis/dist/store.d.ts', but this result could not be resolved under your current 'moduleResolution' setting. Consider updating to 'node16', 'nodenext', or 'bundler'.

Description

I am trying to use your library to implement a RedisStore but the library doesnt export the Class, The various workarounds also didnt work.
Proposed Solution
Update the package.json exports field in @langchain/langgraph-checkpoint-redis:
{
"exports": {
".": "./dist/index.js",
"./store": "./dist/store.cjs",
"./shallow": "./dist/shallow.cjs"
}
}

or add it to the index file where I only see the RedisSaver
