Excellent work @eonwarped, the life cycle of service workers can be very tricky.

This is one of those development problems that definitely takes some digging and astuteness to get right. In addition, it will have significant impact on the project's smoothness of delivery going forward.

You're quite right how this piece of development work is also a sort of mini-tutorial. In fact, you just helped me find some information about workers that I needed in a different context.

Thanks, and well done!
