Background events in progressive web apps? (building an alarm clock app)
<p>I am playing around with progressive web apps, and one scenario I wanted to try building was an alarm clock app.</p>

<p>I figure to make this app work properly, it will have to run in the background and become active once the internal conditions (current time === alarm time) have been met.</p>

<p>Is this possible? Or do progressive web apps not yet have the freedom to operate in the background/access phone features through API's.</p>

<p>Thanks!</p>
