Install

As of v3, the module is ESM

npm install --save require-from-drive

Use

IMPORTANT: Each time the apps script is changed, you'll need to deploy a new version as a web app. Otherwise, your changes won't end up in the live version.

First, follow these steps to set up Google Drive:

1. Create a folder on Google Drive. Name it something like "app secrets"
2. Create an apps script in the folder, and paste the contents of drive_server.js in it.
3. Get the folder ID and put it in line 1 of the apps script
4. Change the default token to something more secure, and give it a description
5. Add separate tokens for each app or server that will request secrets
6. Create a blank, single-column spreadsheet in the folder, and paste its entire URL in the spreadsheetLoggingUrl variable. Logs about requests will be stored in this spreadsheet.
7. Create a version of the apps script
8. Deploy as a web app, and get the url.
9. Set the REQUIRE_FROM_DRIVE_SERVER_ADDRESS environment variable to the web app url
10. Set the REQUIRE_FROM_DRIVE_SERVER_TOKEN to one of the tokens
11. Add sub-directories and files. Paths to files are relative to the folder containing the apps script

Then do this!

import { requireFromDrive } from 'require-from-drive'

const myModule = await requireFromDrive({ path: 'path/to/project/module.js' })
const config = await requireFromDrive({ path: 'path/to/project/config.json' })

A memory cache and a file cache are enabled by default. The file cache uses file names prefixed with .require-from-drive.

The memory cache can be disabled by setting the cache option to false. The file cache can be disabled by setting the cacheInFile option to false.

IMPORTANT: Because there's a file cache, you should add .require-from-drive* to your .gitignore

Test

To run the apps script tests, use the apps script viewer/editor to select "test" from the "Run" menu. An error will be thrown and a message will pop up if any test fails.

Possible improvements

• Limit token access to particular subdirectories or files
• Add pictures to the setup instructions
• Require tokens to be a certain minimum length
