How to refresh the value of a property in Ember automatically

Question

First off I think that the subject question may not contain the correct context in what I am looking for, but I will try to explain myself.

I am fairly new to Ember, and I am looking for a way to take a property and refresh the value of it, periodically instead of based on the view refreshing, action, or a template element causing the property to change.

This is kind of a generic example, but it closely relates to what I am doing:

• I have a utility that calculates the size of objects or in specific to what I am doing it will calculate the size of the localStorage.

• I store the value of that calculation in a property and use it in a "service" and other places throughout the app.

  • Everyplace where I use this property is just a static view, and the user will have no interaction in doing something that will cause an action to update that property.

  any suggestions?

This is one of the ways that Ember Octane is just javascript. You can use setInterval and calculate the value at whatever interval you like then set it to a @tracked property on the service. Whenever your interval function updates the property it will be changed anywhere you've displayed it.
