Angular EXCEPTION: No provider for Http

Import the HttpModule

import { HttpModule } from '@angular/http';

@NgModule({
    imports: [ BrowserModule, HttpModule ],
    providers: [],
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})
export default class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

Ideally, you split up this code in two separate files. For further information read:

https://v2.angular.io/docs/ts/latest/cookbook/rc4-to-rc5.html

https://v2.angular.io/docs/ts/latest/guide/ngmodule.html

>= Angular 4.3

for the introduced HttpClientModule

import { HttpClientModule } from '@angular/common/http';

@NgModule({
  imports: [
    BrowserModule,
    FormsModule, // if used
    HttpClientModule,
    JsonpModule // if used
  ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Angular2 >= RC.5

Import HttpModule to the module where you use it (here for example the AppModule:

import { HttpModule } from '@angular/http';

@NgModule({
  imports: [
    BrowserModule,
    FormsModule, // if used
    HttpModule,
    JsonpModule // if used
  ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

Importing the HttpModule is quite similar to adding HTTP_PROVIDERS in previous version.

With the Sept 14, 2016 Angular 2.0.0 release, you are using still using HttpModule. Your main app.module.ts would look something like this:

import { HttpModule } from '@angular/http';

@NgModule({
   bootstrap: [ AppComponent ],
   declarations: [ AppComponent ],
   imports: [
      BrowserModule,
      HttpModule,
      // ...more modules...
   ],
   providers: [
      // ...providers...
   ]
})
export class AppModule {}

Then in your app.ts you can bootstrap as such:

import { platformBrowserDynamic } from '@angular/platform-browser-dynamic';
import { AppModule } from './app/main/app.module';

platformBrowserDynamic().bootstrapModule(AppModule);

Add HttpModule to imports array in app.module.ts file before you use it.

import { HttpModule } from '@angular/http'; @NgModule({ declarations: [ AppComponent, CarsComponent ], imports: [ BrowserModule, HttpModule ], providers: [], bootstrap: [AppComponent] }) export class AppModule { }

Since rc.5 you have to do something like

@NgModule({
    imports: [ BrowserModule],
    providers: [ HTTP_PROVIDERS ],  
    declarations: [ AppComponent ],
    bootstrap: [ AppComponent ]
})
export default class AppModule { }

platformBrowserDynamic().bootstrapModule(AppModule);

because it was only in the comment section I repeat the answer from Eric:

I had to include HTTP_PROVIDERS

Import HttpModule in your app.module.ts file.

import { HttpModule } from '@angular/http';
import { YourHttpTestService } from '../services/httpTestService';

Also remember to declare HttpModule under imports like below:

imports: [
    BrowserModule,
    HttpModule
  ],

The best way is to change your component's decorator by adding Http in providers array as below.

@Component({
    selector: 'greetings-ac-app2',
    providers: [Http],
    templateUrl: 'app/greetings-ac2.html',
    directives: [NgFor, NgModel, NgIf, FORM_DIRECTIVES],
    pipes: []
})

as of RC5 you need to import the HttpModule like so :

import { HttpModule } from '@angular/http';

then include the HttpModule in the imports array as mentioned above by Günter.

Just include the following libraries:

import { HttpModule } from '@angular/http';
import { YourHttpTestService } from '../services/httpTestService';

and include the http class in providers section, as follows:

@Component({
  selector: '...',
  templateUrl: './test.html',
  providers: [YourHttpTestService]

If you have this error in your tests, you should create Fake Service for all services:

For example:

import { YourService1 } from '@services/your1.service';
import { YourService2 } from '@services/your2.service';

class FakeYour1Service {
 public getSomeData():any { return null; }
}

class FakeYour2Service {
  public getSomeData():any { return null; }
}

And in beforeEach:

beforeEach(async(() => {
  TestBed.configureTestingModule({
    providers: [
      Your1Service,
      Your2Service,
      { provide: Your1Service, useClass: FakeYour1Service },
      { provide: Your2Service, useClass: FakeYour2Service }
    ]
  }).compileComponents();  // compile template and css
}));

**

Simple soultion : Import the HttpModule and HttpClientModule on your app.module.ts

**

import { HttpClientModule } from '@angular/common/http';
import { HttpModule } from '@angular/http';



@NgModule({
 declarations: [
   AppComponent, videoComponent, tagDirective, 
 ],
 imports: [
  BrowserModule, routing, HttpClientModule, HttpModule

],
providers: [ApiServices],
bootstrap: [AppComponent]
})
export class AppModule { }

All you need to do is to include the following libraries in tour app.module.ts and also include it in your imports:

import { HttpModule } from '@angular/http';

@NgModule({
  imports:    [ HttpModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

I faced this issue in my code. I only put this code in my app.module.ts.

import { HttpModule } from '@angular/http';

@NgModule({
  imports:      [ BrowserModule, HttpModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

import { HttpModule } from '@angular/http'; package in your module.ts file and add it in your imports.

I just add both these in my app.module.ts:

"import { HttpClientModule }    from '@angular/common/http'; 

&

import { HttpModule } from '@angular/http';"

Now its works fine.... And dont forget to add in the

@NgModule => Imports:[] array
