Code Review
This pull request updates the dependencies for the Langchain Javascript quickstart to a compatible set of versions, which appears to resolve existing dependency conflicts. The core of the change is to align various @langchain packages with @langchain/core@^0.3.0. This is a positive change for the stability of the quickstart. I have one suggestion to further improve long-term stability by pinning the minor versions of the Langchain packages.

@NirajNandre what's the dependency issue? Do you think perhaps it could be solved by package upgrades? |
