How do I integrate the local_time gem without using the asset pipeline?

How do I add the local_time gem to my project without using the asset pipeline as shown in one of the tutorial videos on building a user forum (https://gorails.com/episodes/forum-time-zones-with-local_time?autoplay=1). More specifically, how do I add the local-time.js file to my app using the local_time gem, but not use the asset pipeline to do it? I see an option to add it using the npm package (see below) but I am not sure how this works and where to put it.

import LocalTime from "local-time"
LocalTime.start()

Please advise.

If you use the gem, you have to use the asset pipeline for it. This is what I would recommend anwyays. The asset pipeline is perfect for these things. Any reason why you're avoiding using the asset pipeline?
