Angular15 came and if you are new then you must check below link:

  1. Angular 15 Tutorials

Here is the code snippet and please use carefully:

1. Very first guys, here are common basics steps to add angular 15 application on your machine and also we must have latest nodejs version(14.17.0) installed for angular 15:

npm install -g @angular/cli

ng new angularform // Set Angular 15 Application on your pc

cd angularform // Go inside project folder

2. Now run below commands to set bootstrap 5 modules into our angular 15 application for responsiveness (optional):

npm install bootstrap

npm i @popperjs/core

3. Now friends we just need to add below code into angularform/angular.json file (optional):

"styles": [
"scripts": [

4. Now guys we will add below code into our angularform/src/app/app.module.ts file:

import { ReactiveFormsModule } from '@angular/forms';

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

5. Now guys we will add below code into our angularform/src/app/app.component.ts file:

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

  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
  //Form variables
registerForm:any = FormGroup;
submitted = false;
constructor( private formBuilder: FormBuilder){}
//Add user form actions
get f() { return this.registerForm.controls; }
onSubmit() {
  this.submitted = true;
  // stop here if form is invalid
  if (this.registerForm.invalid) {
  //True if all the fields are filled
  ngOnInit() {
    //Add User form validations
    this.registerForm ={
    email: ['', [Validators.required,]],
    password: ['', [Validators.required]]

6. Finally we will add below code into our angularform/src/app/app.component.html file:

<div class="container-fluid ps-md-0">
    <div class="row g-0">
      <div class="d-none d-md-flex col-md-4 col-lg-6 bg-image"></div>
      <div class="col-md-8 col-lg-6">
        <div class="login d-flex align-items-center py-5">
          <div class="container">
            <div class="row">
              <div class="col-md-9 col-lg-8 mx-auto">
                <h3 class="login-heading mb-4">Welcome back!</h3>
                <!-- Sign In Form -->
                <form [formGroup]="registerForm" (ngSubmit)="onSubmit()">
                  <div class="form-floating mb-3">
                    <input type="email" class="form-control" id="floatingInput" placeholder="" formControlName="email" class="form-control" [ngClass]="{ 'is-invalid': submitted && }"  id="inputEmail4">
                    <div *ngIf="submitted &&" class="invalid-feedback">
                      <div *ngIf="">Email is required</div>
                      <div *ngIf="">Email must be a valid email address</div>
                    <label for="floatingInput">Email address</label>
                  <div class="form-floating mb-3">
                    <input type="password" class="form-control" id="floatingPassword" placeholder="Password" formControlName="password"[ngClass]="{ 'is-invalid': submitted && f.password.errors }" id="inputPassword4">
                    <div *ngIf="submitted && f.password.errors" class="invalid-feedback">
                      <div *ngIf="f.password.errors.required">Password is required</div>
                    <label for="floatingPassword">Password</label>
                  <div class="form-check mb-3">
                    <input class="form-check-input" type="checkbox" value="" id="rememberPasswordCheck">
                    <label class="form-check-label" for="rememberPasswordCheck">
                      Remember password
                  <div class="d-grid">
                    <button class="btn btn-lg btn-primary btn-login text-uppercase fw-bold mb-2" type="submit">Sign in</button>
                    <div class="text-center">
                      <a class="small" href="#">Forgot password?</a>

7. Now we will add below code into our angularform/src/app/app.component.css file:

.login {
    min-height: 100vh;
  .bg-image {
    background-image: url('');
    background-size: cover;
    background-position: center;
  .login-heading {
    font-weight: 300;
  .btn-login {
    font-size: 0.9rem;
    letter-spacing: 0.05rem;
    padding: 0.75rem 1rem;

Now we are done friends and please run ng serve command to check the output in browser(locahost:4200) and if you have any kind of query then please do comment below.

Note: Friends, I just tell the basic setup and things, you can change the code according to your requirements. For better understanding please watch video above.
