Our team has created an angular 9 new project and it is working perfectly fine on Google Chrome and Firefox but on IE11 I cant see anything. I have tried everything on from the internet followed every blog related to this but I unable to achieve the goal.

Here is my tsconfig.json

    "baseUrl": "./",
    "outDir": "./dist/out-tsc",

I have followed this link https://medium.com/better-programming/how-to-fix-your-angular-app-when-its-not-working-in-ie11-eb24cb6d9920

Also I have seen for others in the posts that they had some error in their console of IE11 but there is no as such any error in my Console window of IE11. Please check this screenshot of IE11. enter image description here

Have you edited the browserslist file? You should remove not before IE 9-11. The browserslist is like below:

> 0.5%
last 2 versions
Firefox ESR
not dead
IE 9-11 # For IE 9-11 support, remove 'not'.

I also made a new angular 9 app and it can work well in IE 11. I added a new tsconfig-es5.app.json file, updated angular.json configuration, edited browserslist then run ng serve --configuration es5. The result is like this. Besides, you don't need to uncomment in polyfills.ts.

My tsconfig.json:

{
  "compileOnSave": false,
  "compilerOptions": {
    "baseUrl": "./",
    "outDir": "./dist/out-tsc",
    "sourceMap": true,
    "declaration": false,
    "downlevelIteration": true,
    "experimentalDecorators": true,
    "module": "esnext",

    "importHelpers": true,
    "target": "es2015",
    "lib": [
      "es2018",
      "dom"
    ]
  },
  "angularCompilerOptions": {
    "fullTemplateTypeCheck": true,
    "strictInjectionParameters": true
  }
}

My package.json:

{
  "name": "angular9",

    "ng": "ng",
