Does anyone know how to use Signer Keys to cast message on Farcaster using NodeJS? I only find examples using mnemonic phrase but it's not what I need. I also asked the same question in the telegram group but so far no answer to fix the error.

Hey Frenk, after getting completing the Signer Requests flow, you can use the private key to create a cast as shown in this example

is it okay to create the signer request using warpcast and than publish it using Farcaster Hub?

Okay. So do I need to create my own hub to interact with Farcaster? I was hoping to avoid to create it and maintain it

yes, during the signer request flow the user will use their ECDSA to publish a SignerAdd message with the key you provided, after which you'll be able to use that key to sign messages like casts on behalf of the user
