Why do any of the Angular imports are not working?

Discussão em 'Angular' iniciado por Gergő Szabó, Junho 24, 2025.

  1. I just se tup a project, and it is compiling succesfully, but every time I try to add a directive, it shows this error, for example for [formGroup]: "Property formGroup is not provided by any applicable directives nor by form element". But if I try ngModel or *ngIf, none of them are working.

    I tried reinstalling everything, deleted node_modules, reinstalled it, created a new project, tried it there. Pulled a project from github and configured it, it compiles, but still not recognizes any of the modules. I have imported every necessary module to the app.module.ts and still not working. I followed step by step everything on tutorials, tried at least 3 tutorial videos and 7 articles, but no success at all.

    This is my app module:

    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { FormsModule, ReactiveFormsModule} from "@angular/forms";
    import { AppRoutingModule } from './app-routing.module';
    import { AppComponent } from './app.component';
    import { LoginComponent } from './login/login.component';
    import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
    import { MatFormFieldModule } from '@angular/material/form-field';
    import { MatInputModule } from '@angular/material/input';
    import { MatButtonModule } from "@angular/material/button";
    import {MatDividerModule} from "@angular/material/divider";
    import { initializeApp,provideFirebaseApp } from '@angular/fire/app';
    import { environment } from '../environments/environment';
    import { provideAuth,getAuth } from '@angular/fire/auth';
    import { provideFirestore,getFirestore } from '@angular/fire/firestore';
    import { AngularFireModule } from "@angular/fire/compat";
    import { OverviewComponent } from './overview/overview.component';

    @NgModule({
    declarations: [AppComponent, LoginComponent, OverviewComponent],
    imports: [
    BrowserModule,
    AppRoutingModule,
    AngularFireModule.initializeApp(environment.firebase),
    BrowserAnimationsModule,
    MatFormFieldModule,
    MatInputModule,
    MatButtonModule,
    MatDividerModule,
    FormsModule,
    ReactiveFormsModule,
    provideFirebaseApp(() => initializeApp(environment.firebase)),
    provideAuth(() => getAuth()),
    provideFirestore(() => getFirestore())
    ],
    providers: [],
    bootstrap: [AppComponent],
    })
    export class AppModule {}


    this my login template:

    <h4 class="text-center m-3">Login</h4>
    <div class="form-container">
    <form [formGroup]="loginForm">
    <input required />
    <input required type="password" />
    <button>Login</button>
    </form>
    </div>
    <h4 class="text-center m-3">Register</h4>
    <div class="form-container">
    <input required />
    <input required type="password" />
    <input required type="password" />
    <button>Register</button>
    </div>


    this is my login ts file:

    import {Component, OnInit} from '@angular/core';
    import { FormBuilder, FormGroup, FormControl } from "@angular/forms";

    @Component({
    selector: 'app-login',
    templateUrl: './login.component.html',
    styleUrls: ['./login.component.scss'],
    })
    export class LoginComponent implements OnInit {

    loginForm: FormGroup;

    constructor(private fb: FormBuilder) {}

    ngOnInit(): void {
    this.loginForm = this.fb.group({
    email: new FormControl(''),
    password: new FormControl('')
    })
    }

    }


    The error is in the template as it says to the [formGroup]: Property formGroup is not provided by any applicable directives nor by form element
