Angular 12: Support was requested for IE 9 & IE 10 in the project's browserslist configuration

Question

First, my problem is different than: Angular 12 warns about requested IE 11 support. Why?

I'm upgrading to Angular 12 and getting this warning.

 Support was requested for IE 9 & IE 10 in the project's browserslist configuration. These browsers are no longer officially supported with Angular v11 and higher

I do have a browserlist file in the root directory. Contents:

# This file is used by the build system to adjust CSS and JS output to support the specified browsers below.
# For additional information regarding the format and rule options, please see:
# https://github.com/browserslist/browserslist#queries

# You can see what browsers were selected by your queries by running:
#   npx browserslist


> 0.5%, last 2 Chrome versions, IE 9-11

In addition, my package.json references it under dependencies as:

 "browserslist": "^4.17.6",

I have also commented the import statements in polyfills.js to support IE9, IE10 and IE11

Please suggest what can I do to get rid of that warning

remove `, IE 9-11` from browserlist file. then nothng would be transpiled to the old code — Andrei, Jan 04 '22 at 18:21

Angular 12 doesn't support IE 9 or IE 10, only IE 11: https://v12.angular.io/guide/browser-support

The last version that supports all 3 is Angular 10: https://v10.angular.io/guide/browser-support

typo ... Angular 10 supports IE9. On Angular 12 IE11 is deprecated, on Angular 13 and 14 IE isn't supported anymore. – danpop Jul 05 '22 at 11:28
