download all files in a google drive folder api

A ready-to-use npm package, Git repo, and Docker image are provided throughout the article. We’ll examine the step-by-step implementation, as well as how to utilize server-side caching to avoid the major pitfalls to avoid such as API usage limits and image hotlinking. The returned Promise resolves to a Stream in object mode to receive data objects for each downloaded file as it arrives.We’re going to walk through the technical process of hooking into Google Drive’s API to source content on a website. folderId: String,Īuth: GoogleAuth | OAuth2Client | JWT | String, For a more detailed explanation of input skip to here. Here's the signature: Promise GoogleDriveFolder (folderId, userId, Options)Ī quick look at all the input and the types. The library exports a single function that returns a Promise that resolves to a Stream. These options are supplied using the conversion options. To change this, supply a transformer function and an optional exportMimeMap if the source file on Google Drive is a Google Workspace file type (Docs, Spreadsheet, Presentation, Drawing, etc). Conversionsīy default, no conversion occurs, data is just passed through as a Buffer (if binary) or a utf8 encoded string. For more information, all options are detailed here. However, If you have different requirements (OAuth2, JWT, etc), you can supply your own pre-resolved auth reference by passing google auth as an 'auth' option. Further, this credential must have the permissions to impersonate the user email passed in as userId for the folder folderId.

By default, this library relies on Environment variable SVC_ACCT_CREDENTIALS to point to a valid Google service account credential file.

This library uses the google api node client, and therefore requires credentials. The original problem must have been that I was making too many requests all at once over a very small time period, resulting in a 403 from the Google Drive service by policy. This was initially puzzling (403 code not sufficient to understand the precise issue), but I solved it by serially streaming the files. I wrote this library to codify my solution to a painful experience in which 403 errors developed during larger folder downloads. This library streams files from a google drive folder, and applies conversions (if desired).
