@purple-dot/purple-dot-react v2.0.2

Purple Dot React Library

The Purple Dot React Library allows merchants to integrate Purple Dot into a React project.

For more info on Purple Dot visit https://www.getpurpledot.com.

Installation

npm install @purple-dot/purple-dot-react@2.0.1

Minimum Requirements

React v16.8 or higher.

Features

This library works with your React components to provide the following:

• Displaying a Pre-order button if there is only pre-order stock left for the variant

• Showing a Purple Dot checkout iframe if the shoppers cart contains a pre-order item

• Adding a Manage Pre-orders iframe to a specified page

• Showing or hiding elements if a product is on pre-order

The current 2.0.0-beta.1 version supports Purple Dot's Combined Bag product only, where shoppers can check out with in-stock and pre-order line items using the same cart. Support for our Express checkout and Multi Bag checkout is coming soon.

Getting started

Product configuration

In order to make some variant(s) of a product available to pre-order:

1. In Shopify, for each relevant variant set the in stock availability level to 0.
2. In the Purple Dot Portal, create a Waitlist for that product. This is where you will define how many units will become available to pre-order and when you expect to fulfill the collected pre-orders. Press Get Help > Managing Your Waitlists > How do I set up a Waitlist? if you need help with this step.

Please note: when a new Waitlist is created, the Purple Dot backend will automatically tick the Continue selling when out of stock option for each product variant with some pre-order stock on said Waitlist. This is required for Purple Dot to correctly integrate into your Online Store. However this will make those variant(s) available to buy across all your sales channels so consider if you need to temporarily remove any other sales channels.

Adding the context provider

To get started with the integration you will need your Purple Dot Api Key. This can be found in the Purple Dot Portal at the bottom of the Integration page. If you do not have access to the portal, please contact us at support@getpurpledot.com to get set up.

Once you have your Api Key, you will need to wrap your App in the PurpleDot component. This must be at or very close to the top of your component tree to make sure that all relevant components are children.

import { PurpleDot } from '@purple-dot/purple-dot-react';

...

const App = () => (
  <PurpleDot apiKey="<API-KEY>">
    <ExampleRouter>
      ...
    </ExampleRouter>
  </PurpleDot>
)

Displaying a Pre-order button on the product page

The code below shows the changes necessary to your Product Detail Page to start showing the Pre-order button.

There are 3 integration points you will need to provide:

1. A fetchAvailability function: This function will need to return the in stock availability levels of the product and its variants.

• NOTE - The function must be memoized to prevent infinite render loops, see https://docs.react-async.com/api/options#promisefn.

2. A renderButton function: This function renders either the Add to Cart Button or the Preorder Button depending on the in stock availability of the selected product variant

3. An onClick function: When the Add to Cart / Pre-order is clicked this function will receive the id of the added variant as well as the line item properties necessary to add.

• NOTE: These line item properties must be added to the cart in order for the checkout to recognize that the item is on pre-order.

import React, { useEffect, useState } from 'react';
import { usePurpleDot, PreorderButton } from '@purple-dot/purple-dot-react';

const ProductPage = ({ product }) => {
  const [selectedVariantId, setSelectedVariantId] = useState(null);
  const availability = usePurpleDot({
    productId: product.id,
    selectedVariantId,
    fetchAvailability,
  });

  return (
    <div class="product-page">
        <PreorderButton
          availability={availability}
          onClick={({ id, properties }) => addToCart({ id, properties })}
          renderButton={(props) => <button {...props} />}
        />
    </div>
  );
}

async function fetchAvailability({ productId }) {
  // Get Shopify inventory quantity for a product and its variants
  return {
    id: 1,
    inventory_quantity: 3,
    variants: [{
      id: 1,
      inventory_quantity: 1,
    }, {
      id: 2,
      inventory_quantity: 0,
    }, {
      id: 3,
      inventory_quantity: 2,
    }],
  };
}

function addToCart({ id, properties }) {
  // Handle adding a variant to cart
}

Showing the Purple Dot Checkout Iframe to the Cart Page

Add the following code to your cart page and pass the current state of the cart to usePurpleDotCheckout. If pre-order items are detected in the cart then Purple Dot's checkout iframe will be displayed over the contents of the cart page.

import { usePurpleDotCheckout } from '@purple-dot/purple-dot-react';

const CartPage = ({ cart }) => {
  const { PreorderCheckout } = usePurpleDotCheckout({ cart });
  
  return <PreorderCheckout cart={cart} />;
}

Adding a Manage Pre-orders Iframe

Add the following code to a new page that shoppers will use to manage their pre-orders. We recommend the /manage-pre-orders path.

import { PreorderSelfService } from '@purple-dot/purple-dot-react';

<PreorderSelfService
  onPreorderCancelled={() => {}}
  onArrangeReturnClicked={() => {}}
/>

usePurpleDot

A hook that returns pre-order availability data for a product and an optional selected variant.

  /* True if the async requests finished and data is available */
  isFulfilled,
  /* True if there was an error loading the data */
  isError,
  /* True if the async requests are in progress and data is not yet loaded */
  isPending,
  data: {
    product: {
      id,
      /* (IN_STOCK|PRE_ORDER|SOLD_OUT) whether the product is available in-stock,
          on pre-order or fully sold out */
      availability,
    },
    /* selectedVariant is only set if a variant is selected */
    selectedVariant: {
      id,
      /* (IN_STOCK|PRE_ORDER|SOLD_OUT) whether the variant is available in-stock,
         on pre-order or fully sold out */
      availability,
    }
  }
} = usePurpleDot({
  /* Product ID https://shopify.dev/api/liquid/objects#product-id */
  productId,
  /* (Optional) The currently selected variant ID */
  selectedVariantId,
  /* A function that takes a productId and returns a promise with the in-stock
     inventory quantities for the product. The returned data should follow this structure:
     
     {
       id: 1, // The product ID
       inventory_quantity: 100 // The total in-stock inventory for the product
       variants: [{
           id: 1, // The variant ID
           inventory_quantity: 50, // The total in-stock inventory for the variant
       }, {
           id: 2,
           inventory_quantity: 50,
       }]
     }

  availability={availability}
