Error: In this configuration Angular requires Zone.js in Angular app in IE11

Question

Im using angular 9 application, on-load of the app Im getting this error in IE11. Error: In this configuration Angular requires Zone.js. And Component doesn't load and shows the above error in console. I tried adding import 'zone.js'. But it didn't work. Also, tried adding in index.html file. But no luck. This issue happens only in IE11. Works fine in Chrome and Firefox.

Answer 1

You need to load libraries as mentioned before:

<script src="node_modules/core-js/client/shim.min.js"></script>
<script src="node_modules/zone.js/dist/zone.js"></script>
<script src="node_modules/reflect-metadata/Reflect.js"></script>
<script src="node_modules/systemjs/dist/system.src.js"></script>

Answer 2

When we import zone.js in index.html, it works fine.
