How to globally set the preserveWhitespaces option in Angular to false?

This will be false by default starting with angular 6

• https://github.com/angular/angular/issues/22027

For now, in JIT mode we can set it as part of CompileOptions:

main.ts

platformBrowserDynamic().bootstrapModule(AppModule, { preserveWhitespaces: false });

For aot we have to add this option to

tsconfig.app.json

{
  "extends": "../tsconfig.json",
  "compilerOptions": {
    "outDir": "../out-tsc/app",
    "baseUrl": "./",
    "module": "es2015",
    "types": []
  },
  "exclude": [
    "test.ts",
    "**/*.spec.ts"
  ],
  "angularCompilerOptions": {
    "preserveWhitespaces": false
  }
}
