Installation

Install the npm package.

npm i ng-password-validator

Import in NgModule:

import { NgPasswordValidatorModule } from 'ng-password-validator';

@NgModule({
    imports: [ NgPasswordValidatorModule ]
})

Usage

Options can be set in the directive tag, so they have the highest priority.

<input type="text" id="password" name="password" placeholder="Password.."
    NgPasswordValidator placement="top">

You may pass as an object:

<input type="text" id="password" name="password" placeholder="Password.."
    [NgPasswordValidator]="options">

Password type as 'range':

options = {
    'placement': 'top',
    'password': {
        'type': "range";
        'min': 6;
        'max': 10;
    },
    'shadow': false,
    'offset': 15,
}

Password type as 'number':

options = {
    'placement': 'top',
    'password': {
        'type': "number";
        'length': 8;
    },
    'shadow': false,
    'offset': 15,
}

Theming( Default value is pro ):

<input type="text" id="password" name="password" placeholder="Password.."
    [NgPasswordValidator]="options">

Theme as 'basic':

options = {
    'placement': 'top',
    'theme': 'basic'
}

Theme as 'pro':

options = {
    'placement': 'top',
    'theme': 'pro'
}

You can also change Popup header and success message:

<input type="text" id="password" name="password" placeholder="Password.."
    [NgPasswordValidator]="options">

options = {
    'heading': 'Password Requirement',
    'successMessage': 'Wow! Password is Strong.'
}

After closing the popup window, you will get one output for password validity (true/false):

<input type="text" id="password" name="password" placeholder="Password.."
    NgPasswordValidator placement="top" (valid)="isValid($event)">

isValid(event: boolean) {
    this.isPasswordValid = event;
}

Set default values

In app.module.ts export the default options like below:

import { NgPasswordValidatorModule, NgPasswordValidatorOptions } from "ng-password-validator";

export const MyDefaultOptions: NgPasswordValidatorOptions = {
    placement: "right",
    rules: {
        "include-symbol": true,
        "include-number": true,
        "include-lowercase-characters": true,
        "include-uppercase-characters": false,
    }
};

And pass your parameters when importing the module:

@NgModule({
    imports: [
      NgPasswordValidatorModule.forRoot(MyDefaultOptions as NgPasswordValidatorOptions)
    ]
})
