The Product Context app is designed to provide essential product data to all child blocks within your store theme.

1. Add the product-context app as a dependency to your store theme's manifest.json file:

     "dependencies": {
   +   "vtex.product-context": "0.x"
     }

2. Install the TypeScript types exported by the app by running the following command:

   vtex setup

Now, you're ready to import components and hooks from the app. Check this example component that displays the product name using data stored in the nearest ProductContext:

// Notice that this is TypeScript, and this code should be in a .tsx file
import React, { FC } from 'react'
import { useProduct } from 'vtex.product-context'

const MyComponent: FC = () => {
  const productContextValue = useProduct();

  return (
    <Fragment>
      {productContextValue?.product?.productName}
    </Fragment>
  )
}

export default MyComponent

The useProduct hook allows your app to retrieve data from the nearest ProductContext relative to its caller. Expect an object with the structure below as the return value:

interface ProductContextState {
  selectedItem?: Item | null
  product: MaybeProduct
  selectedQuantity: number
  skuSelector: {
    selectedImageVariationSKU: string | null
    isVisible: boolean
    areAllVariationsSelected: boolean
  }
  buyButton: BuyButtonContextState
  assemblyOptions: {
    items: Record<GroupId, AssemblyOptionItem[]>
    inputValues: Record<GroupId, InputValues>
    areGroupsValid: Record<GroupId, boolean>
  }
}

Note that if the hook is called outside a ProductContextProvider, the return value may be undefined or an empty object.

The useProductDispatch hook provides a dispatch function to manipulate the nearest ProductContext. The function supports the following actions:

• SELECT_IMAGE_VARIATION: Sets the value for the skuSelector.selectedImageVariationSKU property.
• SET_QUANTITY: Sets the value for the selectedQuantity property.
• SKU_SELECTOR_SET_VARIATIONS_SELECTED: Sets the value for the skuSelector.areAllVariationsSelected property.
• SET_BUY_BUTTON_CLICKED: Sets the value for the buyButton.clicked property.
• SKU_SELECTOR_SET_IS_VISIBLE: Sets the value for the skuSelector.isVisible property.
• SET_SELECTED_ITEM: Sets the value for the selectedItem property.
• SET_ASSEMBLY_OPTIONS: Sets the value for the assemblyOptions property.
• SET_PRODUCT: Sets the value for the product property.
• SET_LOADING_ITEM: Sets the value of whether a selected item is loading.

Thanks goes to these wonderful people:
