Replaces APP_INITIALIZER, ENVIRONMENT_INITIALIZER, and PLATFORM_INITIALIZER with their respective provider functions: provideAppInitializer, provideEnvironmentInitializer, and providePlatformInitializer.

Before

const providers = [
  {
    provide: APP_INITIALIZER,
    useValue: () => { console.log('hello'); },
    multi: true,
  }
];

After

import {provideAppInitializer} from '@angular/core';

const providers = [provideAppInitializer(() => { console.log('hello'); })];
