Uploading a buffer to google cloud storage

.save to save the day! Some code below where I save my "pdf" that I created.

https://googleapis.dev/nodejs/storage/latest/File.html#save

const { Storage } = require("@google-cloud/storage");

const gc = new Storage({
  keyFilename: path.join(__dirname, "./path to your service account .json"),
  projectId: "your project id",
});

      const file = gc.bucket(bucketName).file("tester.pdf");
      file.save(pdf, (err) => {
        if (!err) {
          console.log("cool");
        } else {
          console.log("error " + err);
        }
      });

This is actually easy:

  let remotePath = 'some/key/to/store.json';
  let localReadStream = new stream.PassThrough();
  localReadStream.end(JSON.stringify(someObject, null, '   '));

  let remoteWriteStream = bucket.file(remotePath).createWriteStream({ 
     metadata : { 
        contentType : 'application/json' 
     }
  });

  localReadStream.pipe(remoteWriteStream)
  .on('error', err => {
     return callback(err);      
  })
  .on('finish', () => {
     return callback();
  });

We have an issue about supporting this more easily: https://github.com/GoogleCloudPlatform/gcloud-node/issues/1179

But for now, you can try:

file.createWriteStream()
  .on('error', function(err) {})
  .on('finish', function() {})
  .end(fileContents);
