# Shopping configurations (React Native)

### Customize product info view

You could utilize `FireworkSDK.getInstance().shopping.productInfoViewConfiguration` to customize the shopping CTA button, the Firework PDP link button, and the video product card. The following are sample codes. For further details, please refer to [ProductInfoViewConfiguration](https://eng.firework.com/react-native-firework-sdk/v2/interfaces/ProductInfoViewConfiguration.html).

```typescript
FireworkSDK.getInstance().shopping.productInfoViewConfiguration = {
  // Configure product card for videos
  productCard: {
    // The theme of video product card
    theme: 'light',
    // The corner radius of video product card
    cornerRadius: 10,
    // Specifies if the CTA button should be hidden
    isCtaButtonHidden: true,
    // The text of shopping CTA button: "Buy now" or "Shop now"
    ctaButtonText: 'buyNow',
    // The cta button style of video product card
    // Only supported on iOS
    ctaButtonStyle: {
      textColor: '#000000', // configure text color of product card CTA button
      fontSize: 16, // configure font size of product card CTA button
      iOSFontInfo: {
        fontName: 'Helvetica', // such as "Helvetica", "Helvetica-Bold"
        systemFontStyle: 'italic', // or normal.
        systemFontWeight: 'regular', // or medium, semibold or bold etc.
      },
    },
    // The price configuration of video product card
    priceConfiguration: {
      // The axis of price label: horizontal or vertical
      // Only supported on iOS
      axis: 'horizontal',
      // The label configuration of price
      // Only supported on iOS
      priceLabel: {
        textColor: '#000000',
        fontSize: 16,
        numberOfLines: 2,
        iOSFontInfo: {

          systemFontStyle: 'italic', // or normal.
          systemFontWeight: 'regular', // or medium, semibold or bold etc.
        },
      },
      // The label configuration of original price
      // Only supported on iOS
      originalPriceLabel: {
        textColor: '#000000',
        fontSize: 16,

          systemFontWeight: 'regular', // or medium, semibold or bold etc.
        },
      },
      // The default display order is [priceLabel, originalPriceLabel]
      // When the value is `true`, the order is reversed
      // Only supported on iOS
      isPriceFirst: false,
    },
    // The width of video product card

        systemFontWeight: 'regular', // or medium, semibold or bold etc.
      },
    },
  },
  // Configure Firework PDP link button
  linkButton: { isHidden: true },
  // Configure shopping CTA
  ctaButton: {
    // The text of shopping CTA button: "Shop now" or "Add to card"
    text: 'shopNow',
    // The text color of CTA button

{% hint style="info" %}
If you wish to customize the video product card with a custom view, please refer to [Customize product card on videos using the custom view (React Native)](/firework-for-developers/react-native-sdk/integration-guide-v2/customization-react-native/shopping-configurations-react-native/customize-product-card-using-the-custom-view-restricted-api.md).

### Show cart icon on Firework PDP page

The cart icon is hidden by default. You could show the cart icon by the following codes:

```dart
FireworkSDK.getInstance().shopping.cartIconVisible = true;
```

### Show the red indicator on the cart icon

The host app could use FireworkSDK.getInstance().shopping.setCartItemCount to sync the cart item count to Firework SDK. The count should be greater than or equal to 0. We just use count to show or hide the red indicator on the cart icon. If count > 0, we will show the red indicator on the cart icon. Otherwise, we will hide the red indicator on the cart icon.

```dart
FireworkSDK.getInstance().shopping.setCartItemCount(cartItemCount);
```
