Description: Square In-App Payments SDK for NativeScript
Author: Kyrsten Carlson
Latest version: 1.0.1

# @nativescript/square-in-app-payments

Build remarkable payments experiences in your own apps with Square's In-App Payments SDK for NativeScript.

```bash
npm install @nativescript/square-in-app-payments
```

## Usage

An `after-prepare.js` hook is added by this plugin to handle a build phase for the SDK to run.

You will see the following logs in the console:

```bash
✅ Square SDK Build Phase Script Added to Xcode Build Phases
```

If you do not see these logs, prepare the ios platform again prior to build

```bash
ns prepare ios
```

### Example

`init` must be called in the app.ts or main.ts (bootstrap file).

```ts
import { SquareInAppPayments } from '@nativescript/square-in-app-payments';
SquareInAppPayments.init();
```

You can then setup the SDK options wherever needed.

```ts
import { SquareInAppPayments } from '@nativescript/square-in-app-payments';

const square = new SquareInAppPayments();
// The application ID is required to be set before any other methods from the SDK are called.
square.squareApplicationID = process.env.production ? 'prod-key' : 'sandbox-key';
console.log('Square Application ID:', square.squareApplicationID);

// call from your view bindings top open card entry screen
function startCardEntry() {
  square.startCardEntry({
    collectPostalCode: true,
    isGiftCard: false,
    // theme configuration is only available on iOS
    ...(__APPLE__
      ? {
          themeConfig: {
            tintColor: UIColor.systemBlueColor,
            backgroundColor: UIColor.whiteColor,
            saveButtonTitle: 'Submit',
          },
        }
      : {}),
  });
}

// configure response and completion callbacks
SquareInAppPayments.onResponse = (cardDetails, onComplete) => {
  console.log('Card Details:', cardDetails);

  // handle with your own backend
  fetch('https://randomuser.me/api/')
    .then((response) => {
      onComplete();
    })
    .catch((error) => {
      onComplete('Failed');
    });
};

SquareInAppPayments.onComplete = (cancelled, cardDetails) => {
  console.log('Cancelled:', cancelled);
  console.log('Card Details:', cardDetails);
};
```
