How to load javascript from external source and execute it in Google Apps Script

Question

I am building some google apps scripts and want to load a javascript file located on one of my servers and be able to execute it\'s functions in Google Apps Script.

Answer 1

You can do this:

eval(UrlFetchApp.fetch("my url").getContentText())

Although it would be a lot faster/more efficient to cache the code in ScriptDb or CacheService and only fetch it fresh every 15 minutes or so.
