Violation invariante GatsbyJS: une erreur s'est produite lors de la tentative d'inférence d'un type GraphQL

Liens utiles:

• Récupération de méta-champs avec l'API Storefront

• API Shopify GraphQL Storefront

Récemment, Shopify a publié un moyen de récupérer des méta-champs avec l'API Storefront . Afin d'obtenir un accès en lecture aux méta-champs à partir de l' API Shopify GraphQL Storefront, nous devons ajouter les méta-champs à la liste blanche de l' API Admin de Shopify GraphQL .

J'ai créé 2 plugins locaux:

1. gatsby-source-shopify-metafields qui utilise graphql-request pour updateMetafieldStorefrontVisibility à updateMetafieldStorefrontVisibility du métafield exact sur un produit. Pour exécuter la mutation updateMetafieldStorefrontVisibility faites cd plugins/gatsby-source-shopify-metafields && node lib.js
2. gatsby-source-shopify est une version mise à jour du default gatsby-source-shopify avec les queries.js , nodes.js et gatsby-node.js pour inclure le champ de metafields nouvellement disponible.

Après avoir exécuté updateMetafieldStorefrontVisibility j'ai pu interroger les métafields du produit à l'aide de curl :

require('dotenv').config({
  path: `.env.${process.env.NODE_ENV}`
});

module.exports = {
  siteMetadata: {
    title: `Gatsby Default Starter`,
    description: `Kick off your next, great Gatsby project with this default starter. This barebones starter ships with the main Gatsby configuration files you might need.`,
    author: `@gatsbyjs`,
  },
  plugins: [
    `gatsby-plugin-react-helmet`,
    {
      resolve: `gatsby-source-filesystem`,
      options: {
        name: `images`,
        path: `${__dirname}/src/images`,
      },
    },
    `gatsby-transformer-sharp`,
    `gatsby-plugin-sharp`,
    {
      resolve: 'gatsby-source-shopify',
      options: {
        shopName: `${process.env.SHOPIFY_SHOP_NAME}`,
        accessToken: `${process.env.SHOPIFY_STOREFRONT_ACCESS_TOKEN}`,
        verbose: true
      }
    },
    {
      resolve: `gatsby-plugin-manifest`,
      options: {
        name: `gatsby-starter-default`,
        short_name: `starter`,
        start_url: `/`,
        background_color: `#663399`,
        theme_color: `#663399`,
        display: `minimal-ui`,
        icon: `src/images/gatsby-icon.png`, // This path is relative to the root of the site.
      },
    },
    // this (optional) plugin enables Progressive Web App + Offline functionality

  ],
}
