I have AngularJS application and i am trying to make hybrid app but not able to use AngularJS service insight Angular component : getting error
ERROR Error: Trying to get the AngularJS injector before it being set.
my main.ts is
import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app.module';
platformBrowserDynamic().bootstrapModule(AppModule);
app.module :
import { BrowserModule } from '@angular/platform-browser';
import { NgModule, InjectionToken } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { UpgradeModule, downgradeComponent } from '@angular/upgrade/static';
import { AppComponent } from './app.component';
import { SignInComponent } from "./modules/login/components/sign-in/sign-in.component";
import { authServiceProvider } from './shared/angularJS-upgraded-providers';
@NgModule({
declarations: [
AppComponent,
SignInComponent
],
imports: [
BrowserModule,
UpgradeModule,
FormsModule
],
entryComponents: [
SignInComponent
],
providers: [authServiceProvider],
bootstrap: [SignInComponent]
})
export class AppModule {
ngDoBootstrap() {}
}
angularJS-upgraded-providers.ts :
import { InjectionToken } from "@angular/core";
export const AuthService = new InjectionToken<any>('authService');
export function authServiceFactory(i: any) {
return i.get('authService');
}
export const authServiceProvider = {
provide: AuthService,
useFactory: authServiceFactory,
deps: ['$injector']
};
and sign-in.component.ts :
import { Component, Inject } from '@angular/core';
import {AuthService} from "../../../../shared/angularJS-upgraded-providers";
@Component({
selector: 'sign-in',
template: require('./sign-in.component.html')
})
export class SignInComponent {
constructor(
@Inject(AuthService) private authService: any) {
}
}
When I remove SignInComponent constructor part code compiles well but with @Inject(AuthService) private authService: any) { } part I am getting an error :
Trying to get the AngularJS injector before it being set.
Please give me some suggesting how can I implement angularJS service insight Angular component. Thanks
P.S. my package.json :

And AngularJS version : 1.6.8
This means you are pulling in an AngularJS dependency somewhere in your component tree. It may be in your immediate component or some dependency further down the line.
To debug:
Method 1
Add a debugger
statement immediately before your bootstrap
call:
it('should render the component', () => {
debugger;
bootstrap(Ng2AppComponent);
...
});
injectorFactory
. Use the stack explorer to find calls to resolveNgModuleDep
. These will be recursive, so the top of the stack will be closer to a leaf node, while calls further down the stack will be closer to your component being tested. Look for lines like: tokenKey = "ServiceName"
. This is potentially your offending service. beforeEach(() => {
setupModule({
imports: [
...
],
providers: [
{
provide: '$injector',
useValue: {
get: () => {
return new MockService(); // enhance as needed
},
}
}
],
});
Method 2
$injector
call, and return an empty object. beforeEach(() => {
setupModule({
imports: [
...
],
providers: [
{
provide: '$injector',
useValue: {
get: (serviceName?: string) => {
console.log('looking for serviceName:', serviceName);
return {}; // this will break things differently
},
}
}
],
});
