The What and Why of NPM Modules

Google Apps Script has some amazing built-in stuff. It gives us native access to all Google apps like Sheets and Gmail, seamlessly integrates with GCP services like BigQuery, allows for the building of interfaces with HTML and CardService, facilitates the creation of simple webhooks/APIs and web apps with simple and efficient client-server communication, can make use of any API through UrlFetchApp, and can be bundled into add-ons for efficient distribution. In my experience, it’s enough for 99% of all Google Apps Script developers.

However, one thing that Google Apps Script is missing is modules. NPM has an extremely impressive database of JavaScript modules that don’t automatically integrate with Apps Script. Of course, in Apps Script we have libraries, but the selection is extremely limited and there is no marketplace for those. By the way, who wants to participate in creating one? Let me know in the comments! However, the very first warning on the libraries documentation page notes that libraries make Apps Script slow. Well, Apps Script is already far from being the fastest programming language on Earth, so slowing it down further is not an idea that I’m a fan of!

But what if I told you that there actually is a way to use some NPM modules in Apps Script? You just need to bundle them with Webpack. Not sure what I mean? Keep reading.

How to Write Google Apps Script Code Locally in VS Code and Deploy It With clasp

Google Apps Script Power Up

Why Write GAS Code Locally?

When it came out, the new Google Apps Script IDE was, of course, a big deal. It’s way better than the legacy one. It brought syntax highlighting, keyboard shortcuts, command palette and just a much better UI experience.

In fact the reason it’s so good is that it’s built on top of VS Code Monaco editor. But it’s definitely still far away from what a real VS Code installation can do. You can get all the functionality of the online IDE and much more more: autocomplete, custom themes, installation of modules, linting, snippets, etc.

The bare minimum that you would need is :

  • A VS Code installation (duh!)
  • Node.js + NPM : a JavaScript runtime with a built-in module installer;
  • Autocomplete;
  • clasp: a CLI utility to sync your GAS code

Let’s get into it!
