Template-Driven Forms in Angular

Last updated 29-07-23 03:13

In this comprehensive article, we dive deep into the world of Template-Driven Forms in Angular, exploring their advantages, usage, and best practices. Learn how to streamline your form handling and create dynamic, user-friendly interfaces with ease.


Angular, the popular front-end web development framework, offers various mechanisms to create forms for user input. Among these, Template-Driven Forms stand out as a user-friendly and straightforward approach to form handling. This article aims to provide a detailed overview of Template-Driven Forms in Angular, guiding you through their implementation and best practices.

What are Template-Driven Forms in Angular?

Template-Driven Forms are one of the two main ways to build forms in Angular, the other being Reactive Forms. In Template-Driven Forms, the template (HTML) itself plays a significant role in defining the structure and behavior of the form. Developers can create forms quickly and efficiently by binding form elements directly to the model using directives, without the need for explicit form control instances.

Advantages of Template-Driven Forms

Template-Driven Forms offer several advantages that make them a compelling choice for many developers:

  • Simplicity: They are easy to set up and require less boilerplate code compared to Reactive Forms.
  • Rapid Development: Ideal for prototyping and simple use cases, allowing for quicker development cycles.
  • Declarative Approach: The form structure is defined directly in the template, making it easier to visualize and understand the form's layout.
  • Automatic Tracking: Angular automatically tracks form and input element states, reducing the need for manual subscriptions.
  • Two-Way Data Binding: Changes in the form elements automatically update the underlying model and vice versa.
  • Built-in Validation: Angular provides built-in validation directives to simplify input validation.
  • Error Handling: Form validation and error handling can be easily achieved without writing extensive code.

Getting Started with Template-Driven Forms

To begin working with Template-Driven Forms in Angular, follow these simple steps:

  1. Import FormsModule: Start by importing the FormsModule in your app module to enable Template-Driven Forms features.
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';

  imports: [FormsModule],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
export class AppModule { }
  1. Create the Form: In your component's HTML template, build the form using Angular's form directives such as ngForm, ngModel, and ngSubmit.
  1. Handle Form Submission: In your component class, handle the form submission by defining the onFormSubmit method.
import { Component } from '@angular/core';

  selector: 'app-my-form',
  templateUrl: './my-form.component.html'
export class MyFormComponent {
  onFormSubmit(formData: any) {
    // Process the form data here

Best Practices for Template-Driven Forms

To ensure efficient and maintainable code, consider the following best practices when working with Template-Driven Forms:

  1. Use Built-in Validation Directives: Leverage Angular's built-in validation directives such as required, minlength, maxlength, etc., to simplify input validation.
  2. Opt for Reactive Form as Complexity Grows: For complex forms requiring dynamic form controls, consider transitioning to Reactive Forms to take advantage of their flexibility and advanced features.
  3. Avoid Heavy Business Logic in Template: Keep the template clean and limit the usage of complex business logic directly in the template. Instead, encapsulate it in the component class.
  4. Utilize Form Model: Access the form's underlying model using the ngForm directive, allowing you to interact with the form and its controls programmatically.
  5. Submit Button Interaction: Disable the submit button until the form is valid to prevent erroneous form submissions.
  6. Localization Support: Consider internationalization and localization requirements by using Angular's localization features for form elements.
  7. Clear and Informative Error Messages: Provide clear and informative error messages to guide users when they encounter validation errors.


Can I Mix Template-Driven and Reactive Forms in the Same Application?

Yes, you can use both Template-Driven and Reactive Forms within the same Angular application. This allows you to choose the most suitable approach based on the specific requirements of each form.

Are Template-Driven Forms Suitable for Complex Forms?

While Template-Driven Forms are excellent for simple forms, they may become challenging to manage for highly complex forms. For such scenarios, Reactive Forms offer greater flexibility and maintainability.

How Do I Implement Custom Validation Logic in Template-Driven Forms?

You can implement custom validation logic by creating a custom validator function and binding it to the form control using the ngModel directive. This function should return a validation error if the input is invalid.

Can I Perform Asynchronous Validations with Template-Driven Forms?

Yes, you can perform asynchronous validations with Template-Driven Forms. You can use the AsyncValidatorFn to define asynchronous validation logic, such as validating an email address against a server.

Is It Possible to Reset a Form to Its Initial State?

Yes, you can reset a Template-Driven Form to its initial state by calling the reset() method on the form instance. This will clear all the form controls and reset the form's validity.

How Does Form Submission Work in Template-Driven Forms?

In Template-Driven Forms, form submission is handled using the (ngSubmit) event binding. When the submit button is clicked, the associated method in the component class is executed, and the form data is passed as a parameter.


Template-Driven Forms in Angular offer a straightforward and intuitive way to handle user input and build dynamic interfaces. With their simplicity and declarative approach, they are an excellent choice for quick prototyping and simple forms. However, as the complexity of your forms grows, you may find Reactive Forms more suitable. By following best practices and utilizing Angular's powerful form features, you can create robust and user-friendly forms for your applications.
