TEConnect Angular Component

Angular component for use with Token Exchange Connect utility.
TypeScript Type Defs are exposed, and can be imported from this module as well.

Getting Started

npm install @magensa/te-connect @magensa/te-connect-ng

or

yarn add @magensa/te-connnect @magensa/te-connect-ng

Manual Card Entry

This document will cover the card manual entry component that TEConnect offers.
TEConnect also offers a Payment Request component as well, with both Apple Pay and Google Pay supported. Payment Request Documentation can be found here
Below we will begin with a step-by-step integration of the card manual entry component. If you would prefer to let the code speak, there is an example implementation.

1. The first step is to create a TEConnect instance with your public key. Feed that instance into the TEConnectModuleNg where you are importing it:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { TeConnectNgModule, TEConnect } from '@magensa/te-connect-ng';
import { createTEConnect } from '@magensa/te-connect'

import { AppComponent } from './app.component';

const TE_CONNECT: TEConnect = createTEConnect("__publicKeyGoesHere__");

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    TeConnectNgModule.forRoot(TE_CONNECT)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

2. Next, in your component, define the library markup, and a handler to receive the response of the createPayment method:

import { Component } from '@angular/core';
import { CreatePaymentResponse } from '@magensa/te-connect-ng';

@Component({
  selector: 'app-root',
  template: `
    <lib-te-connect-ng 
        #teconnectng
        (teResponse) = "handleTEResponse($event)"
    ></lib-te-connect-ng>

    <button type="button" (click)="teconnectng.createPayment()">Create Payment Token</button>  
  `,
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'te-connect-example';

  handleTEResponse( response: CreatePaymentResponse ): void {
    console.log(response);
  }
}

3. The above is a minimal example, and will get you started right away. There are additional configuration options, such as:

• Custom Styles configuration
• Optional Billing ZIP Code

createPayment Return Objects

These are the possible objects that will be returned successfully from the createPayment function. Thrown errors will be thrown as any other async method.

1. Success:

{
    magTranID: String,
    timestamp: String,
    customerTranRef: String,
    token: String,
    code: String,
    message: String,
    status: Number,
    cardMetaData: null | {
      maskedPAN: String,
      expirationDate: String,
      billingZip: null | String
    }
}

2. Bad Request

{
    magTranID: String,
    timestamp: String,
    customerTranRef: String,
    token: null,
    code: String,
    message: String,
    error: String,
    cardMetaData: null
}

3. Error (Failed Validation, Timeout, Mixed Protocol, etc)

{ error: String }

Styles API

The styles object (type: StylesConfig) injected is composed of two main properties:

• base
  • General styles applied to the container.
• boxes
  • Styles applied to the input elements.

Below we have the complete API with examples of default values for each.

Base

| Property Name | Parent Property | Input Type | Acceptable Values | Default Value | Notes | |:--:|:--:|:--:|:--:|:--:|:---:| | backgroundColor | base | string | jss color (rgb, #, or color name) | "#fff" | container background color | | margin | wrapper | string or number | jss spacing units (rem, em, px, etc) | '1rem' | container margin | | padding | wrapper | string or number | jss spacing units (rem, em, px, etc) | '1rem' | container padding | | direction | wrapper | string | 'row', 'row-reverse', 'column', 'column-reverse' | 'row' | 'flex-direction' style property | | flexWrap | wrapper | string | 'wrap', 'wrap', 'wrap-reverse' | 'wrap' | 'flex-wrap' style property | | inputType | variants | string | "outlined", "filled", "standard" | "outlined" | template design for input boxes | | inputMargin | variants | string | "dense", "none", "normal" | "normal" | template padding & margins for input boxes | | autoMinHeight | variants | boolean | boolean | false | true will maintain a static margin on each input box that will not grow with validation errors |

{
    base: {
        wrapper: {
            margin: '1rem',
            padding: '1rem',

            flexWrap: 'wrap'
        },
        variants: {
            inputType: 'outlined',
            inputMargin: 'normal',
            autoMinHeight: false
        },
        backgroundColor: '#fff'
    }
}

Boxes

| Property Name | Input Type | Acceptable Values | Default Value | Notes | |:--:|:--:|:--:|:--:|:--:| | labelColor | string | jss color (rgb, #, or color name) | "#3f51b5" | label text and input outline (or underline) color | | textColor | string | jss color (rgb, #, or color name) | "rgba(0, 0, 0, 0.87)" | color of text for input value Also applies :onHover color to outline/underline | | borderRadius | number | numerical unit for css border-radius property | 4 | border radius for input boxes | | inputColor | string | jss color (rgb, #, or color name) | "#fff" | input box background color |

        errorColor: "#f44336",
        inputColor: "#fff"
    }
}

TEConnect Options

The second parameter of the createTEConnect method is an options object. This object is optional. | Property Name | Input Type | Notes | |:--:|:--:|:--:| | billingZip | boolean | See Optional Zip Code Implementation | | tecPaymentRequest | TecPaymentRequestOptions | See the Payment Request README for more info |

type TecPaymentRequestOptions = {
    appleMerchantId?: string,

}

type CreateTEConnectOptions = {
    hideZip?: boolean,
    tecPaymentRequest?: TecPaymentRequestOptions
}

Example Implementation

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { TeConnectNgModule, TEConnect } from '@magensa/te-connect-ng';
import { createTEConnect } from '@magensa/te-connect'

import { AppComponent } from './app.component';

const TE_CONNECT: TEConnect = createTEConnect("__publicKeyGoesHere__");

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    TeConnectNgModule.forRoot(TE_CONNECT)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts

import { Component } from '@angular/core';
import { CreatePaymentResponse, StylesConfig } from '@magensa/te-connect-ng';

@Component({
  selector: 'app-root',
  template: `
    <lib-te-connect-ng 
        #teconnectng
        (teResponse) = "handleTEResponse($event)"
        [stylesConfig] = "myStyles"
    ></lib-te-connect-ng>

    <button type="button" (click)="teconnectng.createPayment()">Create Payment Token</button>  
  `,
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'te-connect-example';

  //Custom Styles are optional.
  myStyles: StylesConfig = {
    base: {
        wrapper: { 
            margin: 0, 
            padding: 0
        },
        variants: {
            inputType: 'outlined',
            inputMargin: 'dense'
        },
        backgroundColor: 'rgb(66, 66, 66)'
    },
    boxes: {
      labelColor: "#BB86FC",
      textColor: "#BB86FC",
      borderRadius: 10,
      errorColor: "#CF6679",
      inputColor: '#121212'
    }
  }

  handleTEResponse( response: CreatePaymentResponse ): void {
    console.log(response);
    const { error } = response;
    if (error) {
      /* 
        Unsuccessful - see message for reason.
        Be aware - there are cases when a response object will return in addition to an error message.
        If this is the case - it will include a magTranId and customerTranRef that can be useful
        if the issue persists. In the case of an error with object, the token will be set to 'null'
      */
    }
    else {
      //Success
    }
  }
}

Example Implementation NoZip

You may choose to hide the "ZIP Code" input field upon creating a TEConnect instance. Once the field is hidden - billingZip becomes an optional parameter to the createPayment function. If you would still like the Payment Token created to include a billingZip - you may supply your own value (as demonstrated below). You may also choose to omit the zip code completely, and the payment token will be created without a billing ZIP code.

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { TeConnectNgModule, TEConnect } from '@magensa/te-connect-ng';
import { createTEConnect } from '@magensa/te-connect'

import { AppComponent } from './app.component';

//The form will not contain a ZIP Code input field with this option.
const TE_CONNECT: TEConnect = createTEConnect("__publicKeyGoesHere__", { hideZip: true });

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    TeConnectNgModule.forRoot(TE_CONNECT)
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts

import { Component } from '@angular/core';
import { CreatePaymentResponse, StylesConfig } from '@magensa/te-connect-ng';

@Component({
  selector: 'app-root',
  template: `
    <lib-te-connect-ng 
        #teconnectng
        (teResponse) = "handleTEResponse($event)"
        [stylesConfig] = "myStyles"
    ></lib-te-connect-ng>

    <button type="button" (click)="teconnectng.createPayment(customerZip)">Create Payment Token</button>  
  `,
  styleUrls: ['./app.component.scss']
})
export class AppComponent {
  title = 'te-connect-example';

  //You may optionally supply a billing ZIP Code if desired - otherwise simply call the function without a parameter.
  customerZip = "90025";

  //Custom Styles are optional.
  myStyles: StylesConfig = {
    base: {
        wrapper: { 
            margin: 0, 
            padding: 0
        },
        variants: {
            inputType: 'outlined',
            inputMargin: 'dense'
        },
        backgroundColor: 'rgb(66, 66, 66)'
    },
    boxes: {
      labelColor: "#BB86FC",
      textColor: "#BB86FC",
      borderRadius: 10,
      errorColor: "#CF6679",
