How to Query within Gatsby

To utilize the Apollo client within your Gatsby project, import graphql-tag and react-apollo. for example:

 
import gql from "graphql-tag"
import { Query } from "react-apollo"
 
const GET_PRODUCT = gql`
  query($handle: String!) {
    shop {
      products(first:1, query: $handle) {
        edges {
          node {
            variants(first: 1) {
              edges {
                node {
                  availableForSale
                }
              }
            }
          }
        }
      }
    }
  }
`
 
export default ({ children, data }) => {
    const product = data.shopifyProduct
 
    return (
        <Query query={GET_PRODUCT} variables={{ handle: product.handle }}>
            {({ loading, error, data }) => {
                if (loading) return <div>Loading stock status...</div>
                if (error) return <div>There was an error!</div>
 
                return (
                <>
                    <h3>Stock Status: {data && data.shop.products && data.shop.products.edges[0].node.variants && data.shop.products.edges[0].node.variants.edges[0].node.availableForSale.toString()}</h3>
                </>
                )
            }}
        </Query>
    )
}
 
export const query = graphql`
    query productQuery($id: String!) {
        shopifyProduct(id: { eq: $id }) {
            handle
        }
    }
`
