Version Update Note

If you upgrade from v1.0.x to v1.1.x (or greater) you will need to change the PasswordStrengthBar import. There are two options:

  1. Change to PasswordStrengthBarModule and add this to the imports section of the @NgModule metadata instead of the declarations (shown below), or
  2. Change to PasswordStrengthBarComponent and update the name in the declarations section to match.

Using the Component

Add Component to Module imports

import { PasswordStrengthBarModule } from 'ng2-password-strength-bar';
//...
@NgModule({
 //...
   declarations: [
        AppComponent,
        //...
    ],
    imports: [
      BrowserModule,
      FormsModule,
      PasswordStrengthBarModule,
      //...
 //...
})
export class AppModule {}

Add Component to your Application

@Component({
    selector: 'my-app',
    template: `
  <h3>Angular 2 Password Strength Bar</h3>
    <div>
       <form name="myForm" novalidate>
            <input type="password" class="form-control" id="password" name="password" placeholder="Enter password"
