Why use npm in Apps Script?

Google Apps Script is quite powerful since it can access other Google services like Google Sheets, Gmail and Google docs. You can take automation to the next level using Google Aps Script.

Being able to use npm modules will make creating and sharing re-usable modules quite easy. This will make it easy to create wrappers for popular services and use those services in your Apps Script project.

In this example project, we are using momentjs and lodash in the Apps Script project.

How is it done?

See the server/lib.js file. It imports the npm module and exports functions that use the imported packages. The api.js has a global function doGet() which gets called by Apps Script to show the web page. If you see the webpack.config.js file, notice that the bundle exposes a global variable AppLib where you can get the functions exported in the bundle.
