Create an active countdown timer within spring boot

lightableMatch commented 2 years ago

Start with WHY?

Why do we need to do work? (Who is requesting this work?) We need a countdown timer to display on the frontend so users will know when the next map rotation will be. Currently the countdown timer is only within the webpage so if the page reloads the countdown timer will restart from the initial timer. This will bring it out of sync with the Apex Legends map timers. Creating a timer object in the service will allow a stable timer to be referenced when the page gets reloaded.

What is the issue? What needs to be resolved?

AS A Web developer
I WANT to create a backend countdown timer
SO THAT the webpage countdown timer remains accurate

Acceptance Criteria

GIVEN I refresh the webpage
WHEN I view the page
THEN I see a countdown timer that coincides with Apex Legends map timers.

Any other notes / resources to share?

This may take a lot of resources to simply decrement a number each second being that the data is passed through different java classes and layers virtually every second.
The entire process may take longer than a second and thus the timer would effectively decrement each second.

Timer used to repeatedly reload when a countdown timer reached.
Now timers when wait a brief moment until after data is updated and displaying a waiting message in the meantime.
