### Implement Custom Password Strength Service in Angular

Source: https://context7.com/antoantonyk/password-strength-meter/llms.txt

Provides an example of creating a custom password strength service by extending IPasswordStrengthMeterService. This allows developers to define their own logic for scoring passwords and providing feedback, including asynchronous operations.

```typescript
import { Injectable } from '@angular/core';
import {
  IPasswordStrengthMeterService,
  FeedbackResult
} from 'angular-password-strength-meter';

@Injectable()
export class CustomPasswordService extends IPasswordStrengthMeterService {
  score(password: string): number {
    let strength = 0;

    if (password.length >= 8) strength++;
    if (password.length >= 12) strength++;
    if (/[a-z]/.test(password) && /[A-Z]/.test(password)) strength++;
    if (/d/.test(password)) strength++;
    if (/[^a-zA-Z\d]/.test(password)) strength++;

    return Math.min(strength, 4);
  }

  scoreWithFeedback(password: string): FeedbackResult {
    const score = this.score(password);
    const feedback = {
      warning: score < 2 ? 'Password is too weak' : null,
      suggestions: [
        password.length < 8 ? 'Use at least 8 characters' : '',
        !/[A-Z]/.test(password) ? 'Add uppercase letters' : '',
        !/\d/.test(password) ? 'Include numbers' : '',
        !/[^a-zA-Z\d]/.test(password) ? 'Add special characters' : ''
      ].filter(s => s !== '')
    };

    return { score, feedback };
  }

  scoreAsync(password: string): Promise<number> {
    return new Promise((resolve) => {
      setTimeout(() => resolve(this.score(password)), 500);
    });
  }

  scoreWithFeedbackAsync(password: string): Promise<FeedbackResult> {
    return new Promise((resolve) => {
      setTimeout(() => resolve(this.scoreWithFeedback(password)), 500);
    });
  }
}

```

### Implement Async Password Strength Evaluation in Angular

Source: https://context7.com/antoantonyk/password-strength-meter/llms.txt

This example demonstrates asynchronous password strength evaluation in an Angular component. By setting `enableAsync` to `true`, the strength calculation is performed asynchronously, preventing UI blocking for potentially intensive computations. The component handles the `strengthChange` event to update the UI and shows a loading indicator while evaluating.

```typescript
import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import { PasswordStrengthMeterComponent } from 'angular-password-strength-meter';

@Component({
  selector: 'app-async-example',
  standalone: true,
  imports: [CommonModule, FormsModule, PasswordStrengthMeterComponent],
  template: `
    <div>
      <h3>Async Password Strength Evaluation</h3>
      <input
        type="password"
        [(ngModel)]="password"
        placeholder="Enter password (async mode)"
      />
      <password-strength-meter
        [password]="password"
        [enableAsync]="true"
        [enableFeedback]="true"
        [minPasswordLength]="8"
        (strengthChange)="handleStrengthChange($event)"
      ></password-strength-meter>
      <div *ngIf="isEvaluating" class="loading">
        Evaluating password strength...
      </div>
      <div *ngIf="strengthResult !== null && !isEvaluating">
        <p>Strength Level: {{ getStrengthLabel(strengthResult) }}</p>
      </div>
    </div>
  `,
  styles: [`
    .loading {
      color: #666;
      font-style: italic;
      margin-top: 10px;
    }
  `]
})
export class AsyncExampleComponent {
  password: string = '';
  strengthResult: number | null = null;
  isEvaluating: boolean = false;

  handleStrengthChange(score: number | null): void {
    this.isEvaluating = false;
    this.strengthResult = score;
  }

  getStrengthLabel(score: number): string {
    const labels = ['Too Weak', 'Weak', 'Fair', 'Good', 'Strong'];
    return labels[score] || 'Unknown';
  }
}
```

--------------------------------

### Use Custom Service for Password Strength Evaluation in Angular

Source: https://context7.com/antoantonyk/password-strength-meter/llms.txt

This example shows how to replace the default password strength evaluation service with a custom one in an Angular component. It injects a custom service (`CustomPasswordService`) by providing it for the `IPasswordStrengthMeterService` token. The component then uses the `PasswordStrengthMeterComponent` with the custom logic.

```typescript
import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';
import {
  PasswordStrengthMeterComponent,
  IPasswordStrengthMeterService
} from 'angular-password-strength-meter';
import { CustomPasswordService } from './services/custom-password.service';

@Component({
  selector: 'app-custom-service',
  standalone: true,
  imports: [CommonModule, FormsModule, PasswordStrengthMeterComponent],
  providers: [
    {
      provide: IPasswordStrengthMeterService,
      useClass: CustomPasswordService
    }
  ],
  template: `
    <div>
      <input
        type="password"
        [(ngModel)]="password"
        placeholder="Test custom service"
      />
      <password-strength-meter
        [password]="password"
        [enableFeedback]="true"
        (strengthChange)="onStrengthChange($event)"
      ></password-strength-meter>
      <div *ngIf="score !== null">
        <p>Custom Score: {{ score }}/4</p>
      </div>
    </div>
  `
})
export class CustomServiceComponent {
  password: string = '';
  score: number | null = null;

  onStrengthChange(score: number | null): void {
    this.score = score;
  }
}
```

### Integrate Password Strength Meter into Angular Reactive Form

Source: https://context7.com/antoantonyk/password-strength-meter/llms.txt

This code shows how to integrate the `PasswordStrengthMeterComponent` into an Angular reactive form for user registration. It includes form validation for email and password, displays the password strength, and disables the submit button if the password is too weak. The `onPasswordStrengthChange` method updates the component's state with the current password strength.

```typescript
import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import {
  ReactiveFormsModule,
  FormBuilder,
  FormGroup,
  Validators
} from '@angular/forms';
import { PasswordStrengthMeterComponent } from 'angular-password-strength-meter';

@Component({
  selector: 'app-registration',
  standalone: true,
  imports: [CommonModule, ReactiveFormsModule, PasswordStrengthMeterComponent],
  template: `
    <form [formGroup]="registrationForm" (ngSubmit)="onSubmit()">
      <div class="form-group">
        <label>Email</label>
        <input
          type="email"
          formControlName="email"
          class="form-control"
        />
      </div>

      <div class="form-group">
        <label>Password</label>
        <input
          type="password"
          formControlName="password"
          class="form-control"
        />
        <password-strength-meter
          [password]="registrationForm.get('password')?.value || ''"
          [enableFeedback]="true"
          [minPasswordLength]="8"
          (strengthChange)="onPasswordStrengthChange($event)"
        ></password-strength-meter>
      </div>

      <button
        type="submit"
        [disabled]="!registrationForm.valid || passwordStrength < 2"
        class="btn-submit"
      >
        Register
      </button>

      <div *ngIf="passwordStrength !== null && passwordStrength < 2" class="warning">
        Password is too weak. Please choose a stronger password.
      </div>
    </form>
  `,
  styles: [
    `
    .form-group { margin-bottom: 20px; }
    .form-control { width: 100%; padding: 10px; }
    .btn-submit { padding: 10px 20px; }
    .btn-submit:disabled { opacity: 0.5; cursor: not-allowed; }
    .warning { color: #d9534f; margin-top: 10px; }
  `]
})
export class RegistrationComponent {
  registrationForm: FormGroup;
  passwordStrength: number | null = null;

  constructor(private fb: FormBuilder) {
    this.registrationForm = this.fb.group({
      email: ['', [Validators.required, Validators.email]],
      password: ['', [Validators.required, Validators.minLength(8)]]
    });
  }

  onPasswordStrengthChange(strength: number | null): void {
    this.passwordStrength = strength;
  }

  onSubmit(): void {
    if (this.registrationForm.valid && this.passwordStrength >= 2) {
      console.log('Form submitted:', this.registrationForm.value);
      // Handle registration logic
    }
  }
}

### Password Strength Service Interface Definition

Source: https://context7.com/antoantonyk/password-strength-meter/llms.txt

Defines the abstract `IPasswordStrengthMeterService` interface and related types (`Feedback`, `FeedbackResult`) for password strength checking. This interface outlines methods for scoring passwords synchronously and asynchronously, with and without feedback (warnings and suggestions).

```typescript
import { Injectable } from '@angular/core';

export interface Feedback {
  warning: string | null;
  suggestions: string[];
}

export interface FeedbackResult {
  score: number | null;
  feedback: Feedback | null;
}

export abstract class IPasswordStrengthMeterService {
  abstract score(password: string): number;
  abstract scoreWithFeedback(password: string): FeedbackResult;
  abstract scoreAsync(password: string): Promise<number>;
  abstract scoreWithFeedbackAsync(password: string): Promise<FeedbackResult>;
}

```

### Angular HTML Usage for Password Strength Meter

Source: https://github.com/antoantonyk/password-strength-meter/blob/master/README.md

This snippet shows how to use the password-strength-meter component in an Angular HTML template. It binds a password variable to the component's password input and enables feedback.

```html
<password-strength-meter [password]="password" enableFeedback />
```
