@buttercup/googledrive-client v2.3.0

Google Drive Client

Client for making basic Google Drive requests

About

This library allows for performing basic actions against Google's RESTful Drive API. It supports fetching directory contents, reading files and writing files. Note that file reading & writing is only supported with text files currently. It uses fetch (cross-fetch) to perform requests, which will obviously work in a reproducible fassion across environments.

Usage

Install the client by running the following:

npm install @buttercup/googledrive-client

The latest version (v2) requires an ESM environment to run. It is not available to standard CommonJS projects.

The library exports a factory which can be used to create client adapters. The factory takes a Google Drive OAuth token.

import { GoogleDriveClient } from "@buttercup/googledrive-client";

const client = new GoogleDriveClient(myToken);

client.getDirectoryContents(/* tree: */ true /* (default) */).then(tree => {
    // ...
})

// Or return a flat structure with all files and directories:
client.getDirectoryContents();

Token expiration or invalid credentials

This library uses Layerr to pass extra error information around, such as when authentication fails while making a request. This makes it easier for downstream libraries to handle such authorisation failures, perhaps by requesting a new token.

If an error is thrown, use Layerr to extract the information from it to test if an authorisation failure has occurred:

client.getDirectoryContents().catch(err => {
    const { authFailure = false } = Layerr.info(err);
    // handle authFailure === true
});

Getting directory contents using a path

This library supports fetching directory contents by using a path, for a more traditional field. This method is not recommended for all use cases as it doesn't support items in the same level with the same name. Consider it experimental.

import { GoogleDriveClient } from "@buttercup/googledrive-client";

const client = new GoogleDriveClient(myToken);

client.mapDirectoryContents("/").then(arrayOfFiles => {
    // ...
})

NB: Items are placed in the root if (and only if) their parents are not resolvable. They may have parent IDs specified in the result - if a parent can be found for a file, it is in that items sub-directory, whereas if the parent cannot be found it is in the root.
