node.js - How to upload an in memory file data to google cloud storage using nodejs?

Question

I am reading an image from a url and processing it. I need to upload this data to a file in cloud storage, currently i am writing the data to a file and uploading this file and then deleting this file. Is there a way i can upload the data directly to the cloud stoage?

static async uploadDataToCloudStorage(rc : RunContextServer, bucket : string, path : string, data : any, mimeVal : string | false) : Promise<string> {
if(!mimeVal) return ''

const extension = mime.extension(mimeVal),
      filename  = await this.getFileName(rc, bucket, extension, path),
      modPath   = (path) ? (path + '/') : '',
      res       = await fs.writeFileSync(`/tmp/${filename}.${extension}`, data, 'binary'),
      fileUrl   = await this.upload(rc, bucket, 
                            `/tmp/${filename}.${extension}`,
                            `${modPath}${filename}.${extension}`)

await fs.unlinkSync(`/tmp/${filename}.${extension}`)

return fileUrl
}

static async upload(rc : RunContextServer, bucketName: string, filePath : string, destination : string) : Promise<string> {
const bucket : any = cloudStorage.bucket(bucketName),
      data   : any = await bucket.upload(filePath, {destination})

return data[0].metadata.name
}
