Angular 4 put a global constant available to zone.js
global
is window
object in a browser as can be seen here:
(function (global, factory) {
typeof exports === 'object' && typeof module !== 'undefined' ? factory() :
typeof define === 'function' && define.amd ? define(factory) :
(factory());
}(this, <------------ `this` points to `window` in global scope
(function () {
...
});
so you can set the variable like this:
window['__Zone_disable_IE_check'] = true;
But you need to do that before zone.js
is loaded. If you load zone.js
in index.html
, add the following:
<script>
window['__Zone_disable_IE_check'] = true;
</script>
<script src="node_modules/zone.js/dist/zone.js"></script>
