JavaScript - The progression of a virtual pet even when the user is offline

Currently, I am utilizing VueJS and MongoDB to develop an interactive virtual pet.

Our approach involves storing user data in localStorage for easy access and retrieval.

I'm exploring the concept of allowing the virtual pet to evolve autonomously (such as decreasing its life gauge) when the user is not actively interacting with the web application. Do I need to incorporate a system that records the time when the user exits the app?

Answer №1

A good practice is to store the time when the user exits the application.

Upon their return (such as when fetching data from the database), you can compare the stored time with the current time and execute any necessary operations based on the time difference.

An alternative approach would be to maintain a server that continuously runs scheduled tasks to ensure real-time updates, but for this scenario, implementing lazy evaluation triggered only upon user request should suffice.
