By Hardik Savani May 2, 2024 Category : Angular

Hey everyone,

In this easy-to-follow guide, we'll explore template-driven forms in Angular 17. I'll break down the process of validating template-driven forms in a straightforward, step-by-step manner. Let's dive into working with Angular 17's template-driven forms, and I'll demonstrate how to validate a form upon submission.

Angular 17 comes with forms that allow us to manage user input using ngModel and ngSubmit. With Template-driven forms in Angular 17, you can create uncomplicated and fundamental forms.

If your Angular 17 application involves a basic form, I recommend using Template-driven Forms. Below, I've provided a simple example of Template-driven Forms with validation in Angular 17.

You need to follow the below step to create template driven form in angular 17.

Step for Template Driven Form in Angular 17

  • Step 1: Create Angular 17 Project
  • Step 2: Update Component ts File
  • Step 3: Form with ngModel
  • Run Angular App

You need to follow the below steps to create template-driven forms in angular 17.

Step 1: Create Angular 17 Project

To begin, create a new Angular app for this demonstration. If you've already created one, there's no need to initiate a new Angular 17 app.

ng new my-new-app

Step 2: Update Component ts File

Import the necessary modules, including FormsModule and ReactiveFormsModule from the '@angular/forms' library, in the app.component.ts file.


import { Component } from '@angular/core';

import { CommonModule } from '@angular/common';

import { RouterOutlet } from '@angular/router';

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


selector: 'app-root',

standalone: true,

imports: [CommonModule, RouterOutlet, FormsModule],

templateUrl: './app.component.html',

styleUrls: ['./app.component.css']


export class AppComponent {

title = 'firstApp';


var firstName = form.firstName;


var lastName = form.lastName;


var comment = form.comment;




Step 3: Form with ngModel

Implement the HTML form with ngModel. Bootstrap classes have been applied for styling.

I used bootstrap class on this form. if you want to add than then follow this link too: Install Bootstrap 5 to Angular 17.

<form #contactForm="ngForm" (ngSubmit)="submit(contactForm.value)">

<div class="form-group">

<input required minlength="3" maxlength="10" ngModel name="firstName" type="text" #firstName="ngModel" class="form-control" id="firstName">

<div class="alert alert-danger" *ngIf="firstName.touched && !firstName.valid">

<div *ngIf="firstName.errors && firstName.errors['required']">First Name is required.</div>

<div *ngIf="firstName.errors && firstName.errors['minlength']">First Name is minimum {{ firstName.errors && firstName.errors['minlength'].requiredLength }} character.</div>

<div *ngIf="firstName.errors && firstName.errors['maxlength']">First Name is maximum 10 character.</div>



<div class="form-group">

<label for="lastName">Last Name</label>

<input required ngModel name="lastName" type="text" #lastName="ngModel" class="form-control" id="lastName">

<div class="alert alert-danger" *ngIf="lastName.touched && !lastName.valid">

Last Name is required.



<div class="form-group">

<textarea required ngModel #comment="ngModel" name="comment" id="comment" cols="30" rows="10" class="form-control"></textarea>

<div class="alert alert-danger" *ngIf="comment.touched && !comment.valid">

Comment is required.
