ANGULAR4-PAYSTACK

This is an angular module that abstracts the complexity of making paystack payments with Angular2+.

USAGE

1. Install the module

npm install --save angular4-paystack

2. Import the module

In your app.module.ts or any module where the component or directive would be used like so:

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

import { Angular4PaystackModule } from 'angular4-paystack';
...

@NgModule({
  imports: [
    Angular4PaystackModule.forRoot('pk_test_xxxxxxxxxxxxxxxxxxxxxxxx'),
  ]
})

export class AppModule {}

3. Implement in your project

There are two available options

AngularPaystackComponent: Renders a button which when clicked loads paystack Inline in an iframe

  <angular4-paystack
    [email]="'[email protected]'"
    [amount]="5000000"
    [ref]="reference"
    [channels]="['bank']"
    [class]="'btn btn-primary'"
    (onClose)="paymentCancel()"
    (callback)="paymentDone($event)"
  >
    Pay with Paystack
  </angular4-paystack>

AngularPaystackDirective: A directive that loads paystack inline in an iframe when clicked

  <button
    angular4-paystack
    [key]="'pk_test_xxxxxxxxxxxxxxxxxxxxxxx'"
    [email]="'[email protected]'"
    [amount]="5000000"
    [ref]="reference"
    [class]="'btn btn-primary'"
    (paymentInit)="paymentInit()"
    (onClose)="paymentCancel()"
    (callback)="paymentDone($event)"
  >
    Pay with Paystack
  </button>

And then in your component.ts

  import { Component, OnInit } from '@angular/core';

  @Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
  })
  export class AppComponent implements OnInit {
    reference = '';
    constructor() {}

    paymentInit() {
      console.log('Payment initialized');
    }

    paymentDone(ref: any) {
      this.title = 'Payment successfull';
      console.log(this.title, ref);
    }

    paymentCancel() {
      console.log('payment failed');
    }

    ngOnInit() {
      this.reference = `ref-${Math.ceil(Math.random() * 10e13)}`;
    }

  }

Also you can use the paystackOptions object like so:

  <button
    angular4-paystack
    [paystackOptions]="options"
    (paymentInit)="paymentInit()"
    (onClose)="paymentCancel()"
    (callback)="paymentDone($event)"
  >
    Pay with Paystack
  </button>

And then in your component.ts

  import { Component } from '@angular/core';
  import { PaystackOptions } from 'angular4-paystack';

  @Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.css']
  })
  export class AppComponent {
    options: PaystackOptions = {
      amount: 50000,
      email: '[email protected]',
      ref: `${Math.ceil(Math.random() * 10e10)}`
    }
    constructor() {}

    paymentInit() {
      console.log('Payment initialized');
    }

    paymentDone(ref: any) {
      this.title = 'Payment successfull';
      console.log(this.title, ref);
    }

    paymentCancel() {
      console.log('payment failed');
    }
  }

Also, you can pass in a key in the component and the directive, in such situation, this key is given a higher preference over the global forRoot key. For example, if you have this is your file

@NgModule({
  imports: [
    Angular4PaystackModule.forRoot('pk_test_1'),
  ]
})

and this in your component

  <button
    angular4-paystack
    [key]="'pk_test_2'"
    [email]="'[email protected]'"
    [amount]="5000000"
    [ref]="reference"
    [class]="'btn btn-primary'"
    (paymentInit)="paymentInit()"
    (onClose)="paymentCancel()"
    (callback)="paymentDone($event)"
  >
    Pay with Paystack
  </button>

Then pk_test_2 would be used instead
