How to download/store image/file inside Google Cloud Storage bucket by just sending image url using npm GCS client?

After searching on Google, i find that there is no function into npm GCS client yet. i found that i will achieve it by running one instance which will have one image download service & it will download image at there for temp purpose & upload it to GCS bucket. in this situation , do i have to pay extra four charges like running instance ,downloading image(temp) bandwidth & also image transfer/storing into GCS bucket. ?

Also find one solutions https://cloudinary.com/documentation/fetch_remote_images cloudinary is exactly what i am looking it.

i am curious to know that is it possible to achieve same kind of thing using GCS bucket. if yes then please tell how ?

I am looking for ideal way.

Assuming you want to use using Google Cloud Client Libraries, I uploaded an image from an external URL, using Node.JS v8.9.4 and npm version 5.6.0 to my bucket, using this code:

const {Storage} = require('@google-cloud/storage'),
      request = require('request'),
      bucket = 'BUCKET_NAME',
      filename = 'FILE_NAME',
      url = 'IMAGE_URL',           
      storage = new Storage({
        projectId: 'PROJECT_ID',
        keyFilename: 'auth.json'
      });   

var file = storage.bucket(bucket).file(filename);

request({url: url, encoding: null}, function(err, response, buffer) {

  var stream = file.createWriteStream({
    metadata: {
      contentType: response.headers['content-type']
    }
  });

  stream.end(buffer);
});

Make sure you set PROJECT_ID, BUCKET_NAME, FILE_NAME and IMAGE_URL; as well as having the Service Account JSON key file in the local directory.

Contents of package.json:

{
 "dependencies": {
  "@google-cloud/storage": "^2.3.3"
 }
}

Run the code with npm start server.js.

If you wish to get a Signed URL for this file, add the following extra code I found in the documentation:

// These options will allow temporary read access to the file
const options = {
  action: 'read',
  expires: '03-17-2025',
};

storage
  .bucket(bucket)
  .file(filename)
  .getSignedUrl(options)
  .then(results => {
    const signed_url = results[0];

    console.log(`The signed URL for ${filename} is ${signed_url}`);
  })
  .catch(err => {
    console.error('ERROR:', err);
  });

Don't forget to set the expiry date to the actual date of expiry you're interested in, by modifying the value of expires.
