GAS/clasp: How do I get autocomplete/intellisense to work in VSCode for 3rd Party libraries

Question

I am using VSCode to edit Google App Script (GAS) code with clasp. I have intellisense working for the core libraries just fine.

(This post helped)

However, I am also using a Firestore library in the ScriptApp project and intellisense is not working for the FirestoreApp.

I've tried included the library Javascript code in my project directory and also in the node_modules directory - but no luck.

Does anyone have any tips? Thanks.

For 3rd Party Libraries, like FirestoreApp, autocompletion does not work.

You will need to create your own .d.ts files (optionally added to DefinitelyTyped).

Another option would be to copy/paste the library into your script, and editors like VS Code will provide light autocompletion (1 level deep). The code doesn't need to be in the node_modules directory.
