Angular's HttpClient is stating that the property '.shareReplay' is not recognized on the type 'Observable'

Excuse me for asking what may seem like a basic question. I'm currently following a tutorial at this link:

I have created the Service as shown in the tutorial, but I am getting an error that says Property '.shareReplay' does not exist on type 'Observable'. I suspect that my imports are incorrect, but I'm struggling to identify the right ones.

import {Injectable} from '@angular/core';
import {HttpClient} from "@angular/common/http";
import {User} from "./model/user";

@Injectable({
  providedIn: 'root'
})
export class AuthenticationService {

  constructor(private http: HttpClient) {
  }

  login(username: string, password: string){
    return this.http.post<User>('/login', {username, password})
      .shareReplay();
  }
}

Answer №1

In the past, this code was valid for versions of rxjs before v5. However, with the new update, you now need to utilize pipable operators as shown below

import {shareReplay } from 'rxjs/operators'



login(username: string, password: string){
    return this.http.post<Body>('/login', {username, password}).pipe(
      shareReplay()
    )
      
  }
