How to get a list of files in a Google Cloud Storage folder using Node.js?

Question

Using bucket.getFiles() it is possible to get all the files in a bucket.

My bucket has thousands of files and I really only want to get metadata on the files in a particular folder.

The documentation is not clear on how to just get the files from a folder. Apparently it is possible to limit the results with a GetFilesRequest but none of the options include a path or a folder, at least not explicitly.

Answer 1

There is an ability to specify a prefix of the required path in options, e.g.

async function readFiles () {
  const [files] = await bucket.getFiles({ prefix: 'users/user42'});
  console.log('Files:');
  files.forEach(file => {
    console.log(file.name);
  });
};

Now it's finally available on documentation (thanks @Wajahath for the update): https://googleapis.dev/nodejs/storage/latest/Bucket.html#getFiles
