Context

I've decided to implement my own firestore checkpoint validation, and now I'm trying to run the test set by this documentation. However, after following the instructions of the documentation I can't seem to get the test to work

Reproduction

I've included a repo for reproduction, here is the link. This also includes the custom firestore checkpointer i've implemented, packages and the system version.

To get it running, ensure that you've:

  1. Node v22.4.1
  2. Run npm install to install the required dependencies
  3. Execute either of the following command, both will throw different errors
    3a. npx @langchain/langgraph-checkpoint-validation ./test/firestore_initializer.ts
    3b. validate-checkpointer ./test/firestore_initializer.ts

Error Details

3a. (Preset ts-jest/presets/default-esm not found)

Running npx @langchain/langgraph-checkpoint-validation ./test/firestore_initializer.ts, threw the following error.

No tests found, exiting with code 1
Run with `--passWithNoTests` to exit with code 0
No files found in /lg-custom-validation/node_modules/@langchain/langgraph-checkpoint-validation/dist.
Make sure Jest's configuration does not exclude this directory.
To set up Jest, make sure a package.json file exists.
Jest Documentation: https://jestjs.io/docs/configuration
Pattern:  - 0 matches

I'm not sure why it's throwing a no test found when there are actually test in the node_modules/@langchain/langgraph-checkpoint-validation/dist

3b. (Preset ts-jest/presets/default-esm not found)

Globally installing checkpoint-validation with the following command, doesn't work.

npm install -g @langchain/langgraph-checkpoint-validation
validate-checkpointer ./src/my_initializer.ts

Running validate-checkpointer ./test/firestore_initializer.ts throws the following error:

node:internal/modules/run_main:115
    triggerUncaughtException(
    ^

[● Validation Error:

  Preset ts-jest/presets/default-esm not found.

  Configuration Documentation:
  https://jestjs.io/docs/configuration
]

Node.js v22.4.1

But my jest configuration does exist here

Hello! In process of updating the @langchain/langgraph-validate-checkpointer from Jest to Vitest, which should allow importing TS source file OOTB #1346

With @langchain/langgraph-validate-checkpointer@0.1.0 we've switched from Jest to Vitest, which should handle ESM and TS by default.
