@kayvank Thanks for this PR. overall, it does lgtm. I will take a deeper look and run through the commands tomorrow am

thanks for sending this in! i've left a few comments if you'd be able to take a look

could this be pinned to 20.12.12? otherwise it's changing the node version for the project and modifying the package-lock.json

@eigen-vi Would you be OK with pinning it to node_20 which is Version: 20.15.1, see nix-package-search
This node version still changes some package versions in the package-lock.json, but not as drastically as before.

To pin to that specific version, I'll have to use the exact URL for each platform binary of the node 20.12.12. Here is an example

I can remove them. However, the rust code is dependent on these environment variables.
