Google Drive Teams Storage

A simple storage to upload files into Google Drive Teams Folders by Multer.

What's Multer?

Multer is a node.js middleware for handling multipart/form-data, which is primarily used for uploading files. It is written on top of busboy for maximum efficiency.

NOTE: Multer will not process any form which is not multipart (multipart/form-data).

F.A.Q.

Can I use this storage to upload file outside a Team Drive?

Yes! But, it's depend of your authentication type. When you use the OAuth authentication you can upload files to you root Google Drive (My Drive).

What kind of authentication can I use?

You can authenticate to google through OAuth or through Service Account. In the example in the 'Use' section, I authenticated by Service Account. When you authenticate with Service Account, you need to create the Shared Drive (Team Drive) and grant permission for the Service Account to access it.
