How can I check what version of OpenSSL I have in my Node app?

Issue

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:

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)'"
