can-zone/register

In order to do it's magic, can-zone has to register handlers for all of the common JavaScript async operations. If you have code (or a dependency with this code) that does:

var st = setTimeout;

And this module loads before can-zone, any time st is used we won't be able to track that within the Zone.

To work around this, can-zone/register is used as a script that you run before any other modules.

In Node

require("can-zone/register");

At the top of your entry-point script.

In the Browser

You can either add a script tag above all others:

<script src="node_modules/can-zone/register.js"></script>

Or, if you're using a module loader / bundler, configure it so that can-zone/register is placed above all others in the bundle.
