You don't even need the var: console.log(require('crypto').randomBytes(48).toString('hex'))
you could go even further and run it as a bash command node -e console.log(require('crypto').randomBytes(48).toString('hex'))
For me, running it in zsh requires quotes.
node -e "console.log(require('crypto').randomBytes(48).toString('hex'))"
The guys from Hapi.js recommends to use base64 encoding.
node -e "console.log(require('crypto').randomBytes(256).toString('base64'));"
node -e "console.log( require('crypto').randomBytes(24).toString('base64url'))"

This can also be run synchronously:
var token = require('crypto').randomBytes(48).toString('hex'); console.log(token);
