Based on this stackoverflow question and answer.

Install

npm install peer-certificate-to-rsa-pubkey

Usage

var rsaPubKey = require('peer-certificate-to-rsa-pubkey')
 
const exampleRequestHandler = (req, res) => {
    const rsaPubKeyBuffer = /* Buffer */ rsaPubKey(res.connection.getPeerCertificate())
    // rsaPubKeyBuffer is a DER represantion of the public key

}

If TLSSocket.getPeerCertificate does not return RSA encrypted public key information an error will be thrown.
