Use JSON object instead of JSON file for Google API Authentication - Node.js

Question

I'm currently using the following code to authenticate as a service account:

const auth = new google.auth.GoogleAuth({
    keyFile: "<path/to/credentials>",
    scopes: [<scopes>],
});

Is there a way to authenticate using a JSON object containing the same content as the keyFile? For example, doing something like this:

const credentials = {
  "type": ...,
  "project_id": ...,
  "private_key_id": ...,
  "private_key": ...,
  "client_email": ...,
  "client_id": ...,
  "auth_uri": ...,
  "token_uri": ...,
  "auth_provider_x509_cert_url": ...,
  "client_x509_cert_url": ...
}

const auth = new google.auth.GoogleAuth({
  keyFile: credentials,
  scopes: [<scopes>],
});

have you tried digging around in the code for the client library to see if there is an overload — Linda Lawton - DaImTo

Changing keyFile: "<path/to/credentials>", to credentials: credentials did the trick as GoogleAuthOptions can also be used with a CredentialBody.
