Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input’ in Angular

This tutorial will show how you can fix the error Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input’ in Angular.

The error message “Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input'” typically occurs in Angular when you are trying to use the ngModel directive on an input element, but Angular doesn’t recognize it because the FormsModule is not imported or configured in your application.

Now, follow the steps below to resolve the issue.

Import FormsModule

The first step is to ensure that you have imported the FormsModule into your main app module (app.module.ts). Open the app.module.ts file and add the following import statement:

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

Then, include FormsModule in the imports array of the @NgModule decorator:

@NgModule({
  imports: [
    // ... other imports
    FormsModule,
  ],
  // ... other module configurations
})
export class AppModule { }

This step is crucial for enabling Angular to recognize and handle [(ngModel)] in your application.

Check FormsModule in Other Modules

If you have multiple modules in your Angular application, ensure that you also import FormsModule in any module where you intend to use [(ngModel)].

For example, if you have a dedicated AuthModule, make sure to include FormsModule in that module as well.

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

@NgModule({
  imports: [
    // ... other imports
    FormsModule,
  ],
  // ... other module configurations
})
export class AuthModule { }

This ensures that the FormsModule is available in the specific module where you want to use [(ngModel)].

Consider ReactiveFormsModule

If you are using ReactiveFormsModule in your application, make sure to import it alongside FormsModule in the respective module(s). For example, in app.module.ts:

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

@NgModule({
  imports: [
    // ... other imports
    FormsModule,
    ReactiveFormsModule,
  ],
  // ... other module configurations
})
export class AppModule { }

This step is necessary when working with reactive forms alongside template-driven forms.

By following these steps, you should resolve the “Can’t bind to ‘ngModel’ since it isn’t a known property of ‘input’” issue in your Angular application. Importing FormsModule in the main app module and other relevant modules ensures that Angular recognizes and handles [(ngModel)] correctly, enabling two-way data binding for your form inputs.
