Push notification for separate Angular 2 Client and Laravel PHP Backend
<p>Currently, I'm developing an e-commerce App that serves as a portal for multiple games so they can purchase goods from the portal with their in-game currencies, they have to do a game-portal binding before they could convert or buy things with their in-game currencies.</p>

<p>The binding process starts when a client requests to bind to certain game and receive a series of Code from backend server, and client would enter the code into their game (IOS / Android), if they succeed, it pushes notification to web browser for updates.</p>

<p>As for the Push notification, other than using a poll, what do you think i should use ?</p>

<ul>
<li>Backend : PHP Laravel (web service)</li>
<li>Frontend : Angular 2</li>
<li>Server : Fedora</li>
</ul>
