Angular provides a powerful and flexible framework for building modern web applications. One of its key features is two-way data binding, which allows you to keep the model and view in sync effortlessly. The [(ngModel)] directive is commonly used for this purpose, particularly with form elements like input fields. However, developers may occasionally encounter the “Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input'” error. In this article, we will discuss the causes of this error and provide solutions to fix it.

Understanding the Error

The “Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input'” error occurs when Angular cannot recognize the [(ngModel)] directive being used with an input element. This error usually arises when you have not imported the FormsModule, which contains the ngModel directive, into your application module or the specific feature module where it is being used.

Fixing the Error

To resolve the “Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input'” error, follow these steps:

  1. Install the FormsModule:

First, ensure that you have the FormsModule installed in your Angular project. If you are using Angular CLI, the FormsModule is already installed by default. Otherwise, you can install the Angular Forms package by running the following command:

npm install @angular/forms
  1. Import FormsModule:

Next, you need to import the FormsModule into the NgModule where you are using the [(ngModel)] directive. This is typically the AppModule or a specific feature module.

Open the app.module.ts file (or the corresponding feature module) and import the FormsModule:

import { FormsModule } from '@angular/forms';
  1. Add FormsModule to the imports array:

After importing the FormsModule, add it to the imports array in the @NgModule decorator:

  declarations: [
    // ...
  imports: [
    // ...
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }
  1. Use [(ngModel)] correctly in your template:

Now that you have imported the FormsModule, you should be able to use [(ngModel)] with input elements in your template. Here’s an example of how to use [(ngModel)] correctly:

<input [(ngModel)]="yourModel" type="text">

Ensure that you have a corresponding model property (e.g., “yourModel”) defined in your component class.


The “Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input'” error can be resolved by ensuring that the FormsModule is installed and imported correctly into your Angular module. By addressing this issue, you can take advantage of Angular’s powerful two-way data binding feature and create more efficient, dynamic web applications. Remember that proper configuration and management of your Angular modules play a crucial role in preventing errors like this and ensuring a smooth development experience.
