Angular 7 application is not running in IE11

Hi ,

Angular 7 application is not running in IE11 eventhough updated polyfills.ts file as suggested in comments of same file.

I have made chnages in polyfills.ts as following:

/** IE9, IE10 and IE11 requires all of the following polyfills. **/ import 'core-js/es6/symbol'; import 'core-js/es6/object'; import 'core-js/es6/function'; import 'core-js/es6/parse-int'; import 'core-js/es6/parse-float'; import 'core-js/es6/number'; import 'core-js/es6/math'; import 'core-js/es6/string'; import 'core-js/es6/date'; import 'core-js/es6/array'; import 'core-js/es6/regexp'; import 'core-js/es6/map'; import 'core-js/es6/set';

uncommenting the lines for classlist.js and web-animations-js

Thanks & Regards

While Internet Explorer 11 has been deprecated for a while now, Microsoft still provides security updates and technical support. However, IE11 does not support many new features which are already working in other browsers, like Google Chrome, or which will come out in the future. That’s why it’s necessary to use polyfills if you still want your application to work in IE11.

Sometimes, your application may throw errors in IE11, even when it is working fine in other browsers. There can be numerous reasons why your Angular application is not working, including:

Missing polyfills in polyfills.ts.
Using a "); background-size: 1px 1px; background-position: 0px calc(1em + 1px);">TypeScript target version which IE11 does not support
