Which JavaScript library should I use to sign a transaction hash? I don’t want to sign a transaction object. I simply want to sign the hash so I'll have a signature, not a signed transaction object.

After a little deeper research I've found how this is done using the secp256k1 library in the ethereumjs-util code:

const sig = secp256k1.sign(msgHash, privateKey)

Where msgHash is a Buffer containing the transaction hash. sig.signature is the signature hex code.
