Javascript NodeJS创建CSV直接写入Google存储

我试着用几种不同的方法来解决这个问题，但结果是一无所获。有许多csv转换器，但它们似乎都写入本地文件（这在应用程序引擎上是不允许的）。我想把文件直接写到谷歌存储桶

很简单

app.get('/', (req, res) => {
  var writer = csvWriter()
  writer.pipe(fs.createWriteStream('out.csv')); // bucket.upload('out.csv);
  writer.write({hello: "world", foo: "bar", baz: "taco"})
  writer.end();
});`

钉死它

const blob = bucket.file('file.csv');
const blobStream = blob.createWriteStream({
  resumable: false,
});

app.get('/', (req, res) => {
  var writer = csvWriter();
  writer.pipe(blobStream);
  writer.write({hello: "world", foo: "bar", baz: "taco"})
  writer.end();
  res.end();
});
