Background task

An simple function wrapper around requestIdleCallback that queues tasks and runs them sequentially.

The main purpose is to be able to run maintainance functions that are not a good fit for a web worker context (i.e. methods that require the DOM).

Usage

Wrap your function.

const task = backgroundTask(() => {
	// do stuff
});

Call task as you would any other function that has no return value. The return value of a background task is true if the task was queued to requestIdleCallback immediately or false if there are previous invocations queued ahead of it.

Calling a task multiple times will queue the passed parameters and execute the task sequentially the same number of times.
