electron - Sleeping application on raspberry pi (and starting screensaver)

Question

I have an Electron application that runs on a Debian Buster distro on a Raspberry Pi 3A+. We don't start the desktop and use startx/xinit to run the app. The device has a custom hat to run the screen and a solenoid. The device currently acts like a kiosk and never goes to sleep. The interface is quite simple and activates a solenoid when an onscreen button is pressed and deactivates when released.

When the device sits for a few days, I've noticed there is a second or so delay before the solenoid is activated after an onscreen button press.

Not sure if the app eventually "sleeps" and needs to be woken up.

• Is there a way to stop this behavior if that is indeed what is happening?
• Is there a simple way to check if that's happening?
• Or can we implement a screen saver that upon a touch event wakes up the app and kills the screensaver? Not sure how xscreensaver works under the hood.

I'm sure I'm missing a few important details so ask away and i'll provide. Much appreciation for any help!
