I'm learning Angular looking for help in fixing the error: I'm following this link : https://github.com/angular/angularfire2/blob/master/docs/install-and-setup.md to create a angular small app with angular2 and angularfirestore2
but when I hit ng serve I am getting the below error in browser console..
StaticInjectorError[AngularFirestore]:
StaticInjectorError[AngularFirestore]:
NullInjectorError: No provider for AngularFirestore!

I tried googling it but didn't find the exact solution nothing worked for me :(,
Here is what I followed: 1) Installed Node Version 8.9.1 2) npm install -g @angular/cli --> Version 1.5.2 3) ng new 'project-name' 4) npm install angularfire2 firebase --save
Here are my app.module.ts file:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { AngularFireModule } from 'angularfire2';
import { environment } from '../environments/environment';
@NgModule({
imports: [
BrowserModule,
AngularFireModule.initializeApp(environment.firebase)
],
declarations: [ AppComponent ],
bootstrap: [ AppComponent ]
})
export class AppModule {}
app.component.ts:
import { Component } from '@angular/core';
import { AngularFirestore } from 'angularfire2/firestore';
import { Observable } from 'rxjs/Observable';
@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
title = 'app';
constructor(db: AngularFirestore) {}
}
environemnt.ts:
export const environment = {
production: false,
firebase: {
apiKey: 'xxxxx',
authDomain: 'aaaaaaa',
databaseURL: 'bbbbbbbbbbbbbbbbbb',
projectId: 'aaaaaaaaaaaaaa',
storageBucket: 'aaaaaaaaaaaa',
messagingSenderId: 'aaaaaaaaaaaaa'
}
};
then ng serve, and I am getting the above error...

I had the same issue while adding firebase to my Ionic App. To fix the issue I followed these steps:
npm install @angular/fire firebase --save
In my app/app.module.ts:
...
import { AngularFireModule } from '@angular/fire';
import { environment } from '../environments/environment';
import { AngularFirestoreModule, SETTINGS } from '@angular/fire/firestore';
@NgModule({
declarations: [AppComponent],
entryComponents: [],
imports: [
BrowserModule,
AppRoutingModule,
AngularFireModule.initializeApp(environment.firebase),
AngularFirestoreModule
],
providers: [
{ provide: SETTINGS, useValue: {} }
],
bootstrap: [AppComponent]
})
Previously we used FirestoreSettingsToken instead of SETTINGS. But that bug got resolved, now we use SETTINGS. (link)
In my app/services/myService.ts I imported as:
import { AngularFirestore } from "@angular/fire/firestore";
For some reason vscode was importing it as "@angular/fire/firestore/firestore";I After changing it for "@angular/fire/firestore"; the issue got resolved!
I take that to my app.module. After the imports it should be works
providers: [
{ provide: LocationStrategy, useClass: HashLocationStrategy },
{ provide: FirestoreSettingsToken, useValue: {} }
],

Weird thing for me was that I had the provider:[], but the HTML tag that uses the provider was what was causing the error. I'm referring to the red box below:
It turns out I had two classes in different components with the same "employee-list.component.ts" filename and so the project compiled fine, but the references were all messed up.
Change Your Import From :
import { AngularFirestore } from '@angular/fire/firestore/firestore';
To This :
import { AngularFirestore } from '@angular/fire/firestore';
This solve my problem.
import angularFirebaseStore
in app.module.ts
and set it as a provider like service
Open: ./src/app/app.module.ts
And import Firebase Modules at the top:
import { environment } from '../environments/environment';
import { AngularFireModule } from 'angularfire2';
import { AngularFirestoreModule } from 'angularfire2/firestore';
And VERY IMPORTANT:
Remember to update 'imports' in NgModule:
@NgModule({
declarations: [
AppComponent,
OtherComponent // Add other components here
...
],
imports: [
BrowserModule,
AngularFireModule.initializeApp(environment.firebase, 'your-APP-name-here'),
AngularFirestoreModule
],
...
})
Give it a try, it shall now work.
For detailed information follow the angularfire2 documentation:
https://github.com/angular/angularfire2/blob/master/docs/install-and-setup.md
Good luck!
For AngularFire2 Latest version
Install AngularFire2
$ npm install --save firebase @angular/fire
Then update app.module.ts file
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { FormsModule } from '@angular/forms';
import { AngularFireModule } from '@angular/fire';
import { AngularFireDatabaseModule } from '@angular/fire/database';
import { environment } from '../environments/environment';
import { AngularFirestoreModule } from '@angular/fire/firestore';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
AngularFireModule.initializeApp(environment.firebase),
AngularFirestoreModule,
AngularFireDatabaseModule
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
Check FireStore CRUD operation tutorial here
Adding AngularFirestoreModule.enablePersistence()
in import section resolved my issue:
imports: [
BrowserModule, AngularFireModule,
AngularFireModule.initializeApp(config),
AngularFirestoreModule.enablePersistence()
]
I had same issue and below is resolved.
Old Service Code:
@Injectable()
Updated working Service Code:
@Injectable({
providedIn: 'root'
})
I solved this problem by just removing firestore from:
import { AngularFirestore } from '@angular/fire/firestore/firestore';
in my component.ts file. as use only:
import { AngularFirestore } from '@angular/fire/firestore';
this can be also your problem.
