google-drive-dwn (Google Drive File Downloader)

Purpose

google-drive-dwn is a simple way to download a shared file from Google Drive.

The module can perform:

• downloading files with binary content
• downloading Google Doc files and convert them to the specified format
• restricting maximum file size
• assigning unique file names

Note: This module was developed for Google Drive API v3

You can use the module to download files one by one. This doesn't support multiple downloading.

Installation

Before starting you have to install googleapis

npm install googleapis@27 --save

When googleapis has been installed you can run:

npm install google-drive-dwn --save

NOTE: During the installation you will be asked for a few questions. So you should be prepared.

1. Please put credentials.json in the root of your app and press Enter

At this point, you should enable the Drive API, download JSON-file (Google Console - APIs & Services - Credentials) and ensure it is named credentials.json (see below)

Put the file and press Enter

2. Enter the scopes

List of scopes

If you want to enter more then one scope you should separate them with a comma

For example: https://www.googleapis.com/auth/drive.readonly,https://www.googleapis.com/auth/drive.metadata

3. Browse to the provided URL in your web browser.

If you are not already logged into your Google account, you will be prompted to log in. If you are logged into multiple Google accounts, you will be asked to select one account to use for the authorization.

Click the Accept button.

Copy the code you're given, paste it into the command-line prompt, and press Enter.

It will create a token.json in the root of your app

After installation

Now you can move and/or rename the files credentials.json and token.json

You will need them later when you are ready to use the module.
