I'm having networking errors, and I'd like to look at what version of OpenSSL my app is running.
Node is released with a version of OpenSSL that has been tested to ensure it is working with that version of Node, as specified here: https://nodejs.org/en/docs/meta/topics/dependencies/#openssl
In order to check out what's running, you can use see what your app is using with
heroku run 'node -e "console.log(process.versions)" | grep openssl'
You can also output all of the dependencies versions:
heroku run 'node -e "console.log(process.versions)"'
In order to check dependency versions from within a Node IDE or a Heroku dyno, run with Node:
node -e 'node -e "console.log(process.versions)"'
