How to use?

Use the formatting directives

You can use the formatting directives on your input fields.

1. Import the NgXCreditCardsModule in the desired module. This module exports all the directives, so you can use this in the AppModule or any other SharedModule.

import { NgModule } from '@angular/core';
 
import { NgXCreditCardsModule } from 'ngx-credit-cards';
 
import { AppComponent } from './app.component';
 
@NgModule({
  imports: [NgXCreditCardsModule],
  declarations: [AppComponent],
  bootstrap: [AppComponent]
})
export class AppModule {
}

1. Add one of three available directives to your inputs 2.1 Credit Card Format Directive ccNum:

<input type="tel" autocomplete="cc-number" id="cc-number" ccNum>

This directive will also apply a class to the input of the card type. It applies whatever class cardType returns.

2.2 Credit Card Expiration Date Directive ccExp. It formats the date to type: MM/YY or MM/YYYY:

<input type="tel" type="tel" autocomplete="cc-exp" id="cc-exp" ccExp>

2.3 Credit Card Cvc Directive ccCvc:

<input type="tel" type="tel" autocomplete="cc-cvc" id="cc-csc" ccCvc>

Custom validators

You can import and use custom FormGroup validators for Angular Reactive Forms. Validators are available for card number, cvc and expiration date.

Import the custom validators to your component:

// These imports are just so you know what we use in the example below. Include if needed.
import { FormGroup, FormBuilder, Validators } from '@angular/forms';
 
 
import { CreditCardValidator } from 'ngx-credit-cards';

Now use the validators with your form group:

 
this.formBuilder = new FormBuilder();
 
this.formGroup = this.formBuilder.group({
  cardNumber: ['', [CreditCardValidator.validateCardNumber],
  cardExpDate: ['', [CreditCardValidator.validateCardExpiry],
  cardCvv: ['', [CreditCardValidator.validateCardCvc],
  cardName: ['', Validators.compose([Validators.required, Validators.minLength(2)])],
});

An example of use with validators would be:

<div [ngClass]="{'invalid':mainForm.submitted && formGroup.controls.cardNumber.errors}">
  <input type="tel" formControlName="cardNumber" autocomplete="cc-number" id="cc-number" ccNum>
</div>

That's it! Enjoy, contribute and have fun.
