title: Angular: How to set downloading spinner when there can be n-number of items that can be downloaded
body: <p>I have n-number of items that can be downloaded dependent on the user. Normally when I have one item I would create a variable set that one to false and when the subscribe starts set it to true and when it finishes back to false. Now I have to do it for multiple items that the user self can download so setting the variables in the component is not an option. What would be the right way to implement this?</p>
