Shopify Storefront Data Hooks

Collection of hooks and data fetching functions to integrate Shopify in a React application. Designed to work with Next.js Commerce.

Getting Started

1. Install dependencies:

yarn install shopify-buy
yarn install -D @types/shopify-buy

3. Environment variables need to be set:

SHOPIFY_STORE_DOMAIN=
SHOPIFY_STOREFRONT_ACCESS_TOKEN=
NEXT_PUBLIC_SHOPIFY_STORE_DOMAIN=
NEXT_PUBLIC_SHOPIFY_STOREFRONT_ACCESS_TOKEN=

4. Point the framework to shopify by updating tsconfig.json:

"@framework/*": ["framework/shopify/*"],
"@framework": ["framework/shopify"]

Modifications

These modifications are temporarily until contributions are made to remove them.

Adding item to Cart

// components/product/ProductView/ProductView.tsx
const ProductView: FC<Props> = ({ product }) => {
  const addToCart = async () => {
    setLoading(true)
    try {
      await addItem({
        productId: product.id,
        variantId: variant ? variant.id : product.variants[0].id,
      })
      openSidebar()
      setLoading(false)
    } catch (err) {
      setLoading(false)
    }
  }
}

Proceed to Checkout

// components/cart/CartSidebarView/CartSidebarView.tsx
import { useCommerce } from '@framework'

const CartSidebarView: FC = () => {
  const { checkout } = useCommerce()
  return (
    <Button href={checkout.webUrl} Component="a" width="100%">
      Proceed to Checkout
    </Button>
  )
}

General Usage

CommerceProvider

Provider component that creates the commerce context for children.

import { CommerceProvider } from '@framework'

const App = ({ children }) => {
  return <CommerceProvider locale={locale}>{children}</CommerceProvider>
}

export default App

useCommerce

Returns the configs that are defined in the nearest CommerceProvider. Also provides access to Shopify's checkout and shop.

import { useCommerce } from 'nextjs-commerce-shopify'

const { checkout, shop } = useCommerce()

• checkout: The information required to checkout items and pay (Documentation).
• shop: Represents a collection of the general settings and information about the shop (Documentation).

Hooks

usePrice

Display the product variant price according to currency and locale.

import usePrice from '@framework/product/use-price'

const { price } = usePrice({
  amount,
})

Takes in either amount or variant:

• amount: A price value for a particular item if the amount is known.
• variant: A shopify product variant. Price will be extracted from the variant.

useAddItem

import { useAddItem } from '@framework/cart'

const AddToCartButton = ({ variantId, quantity }) => {
  const addItem = useAddItem()

  const addToCart = async () => {
    await addItem({
      variantId,
    })
  }

  return <button onClick={addToCart}>Add To Cart</button>
}

useRemoveItem

import { useRemoveItem } from '@framework/cart'

const RemoveButton = ({ item }) => {
  const removeItem = useRemoveItem()

  const handleRemove = async () => {
    await removeItem({ id: item.id })
  }

  return <button onClick={handleRemove}>Remove</button>
}

useUpdateItem

import { useUpdateItem } from '@framework/cart'

const CartItem = ({ item }) => {
  const [quantity, setQuantity] = useState(item.quantity)
  const updateItem = useUpdateItem(item)

  const updateQuantity = async (e) => {
    const val = e.target.value
    await updateItem({ quantity: val })
  }

  return (
    <input
      type="number"
      max={99}
      min={0}
      value={quantity}
      onChange={updateQuantity}
    />
  )
}
