Converting a generated keypair into a base58 or seed phrase?

Question

I did the following in my html file in the chrome console. After I get the following public and private keypair. How do I convert it into a base58 or seed phrase?

The docs below don't state how to go about it:

Answer 1

For converting your Public Key into base58, look at this reference.

Also, it is not possible to generate a mnemonic from a Keypair.

However, the vice-versa is true, as highlighted in the docs you linked.

Answer 2

const keypair = solanaWeb3.Keypair.generate();
const base58 = keypair.publicKey().toBase58();
