What do you want to automate

with SFTP (key-based auth) and Google Cloud?

module.exports = defineComponent({
  props: {
    sftp: {
      type: "app",
      app: "sftp",
    }
  },
  async run({steps, $}) {
    const Client = require('ssh2-sftp-client');
    
    const { 
      host,
      username,
      privateKey,
    } = this.sftp.$auth
    
    const config = {
      host,
      username,
      privateKey,
    }
    
    const sftp = new Client()
    
    await sftp.connect(config)
    this.cwd = await sftp.cwd();
    return await sftp.end();
  },
})

module.exports = defineComponent({
  props: {
    google_cloud: {
      type: "app",
      app: "google_cloud",
    }
  },
  async run({steps, $}) {
    // Required workaround to get the @google-cloud/storage package
    // working correctly on Pipedream
    require("@dylburger/umask")()
    
    const { Storage } = require('@google-cloud/storage')
    
    const key = JSON.parse(this.google_cloud.$auth.key_json)
     
    const storage = new Storage({
      projectId: key.project_id,
      credentials: {
        client_email: key.client_email,
        private_key: key.private_key,
      }
    })
    
    await storage.authClient.getCredentials()
    return {
      status: "success",
      authenticated: true,
      projectId: key.project_id,
      serviceAccount: key.client_email
    }
  },
})
