Important

This template is designed for developers who are already familiar with the GraphQL Storefront API and have prior experience building headless storefronts.

🚀 Get Started

Note

Nitrogen provides a solid foundation for headless Shopify development in Nuxt, but comes with opinionated choices regarding project structure and organization. Feel free to customize the queries, functions, pages, and components to match your project's specific needs!

Shopify

Before using Nitrogen, you must configure your Shopify store as follows:

1. Within your Shopify admin dashboard, create a custom app and configure the necessary Storefront API permissions needed for your project. Enable all Storefront API access scopes to keep things simple. Once the app is created, retrieve your storefront API access token to use in the project’s environment variables.

2. To support international currencies and localized experiences, enable Markets within your Shopify admin dashboard. Navigate to Settings > Markets > Preferences and configure your global currencies. This ensures that customers can see prices in their local currency and switch markets if needed.

3. To enable product filtering, install the Shopify Search & Discovery app and set up basic filters. This template uses the availability, product type, size, and color filter options. You'll likely need to remove some default filter options, or you can add more filters if needed.

4. Additionally, you'll want to add a custom related_products metafield to display related products on your product pages. This metafield allows you to reference the full data of related products, which is ideal for managing matching color swatches, media, and more.

Nuxt

To begin using Nitrogen, you'll need to set up the following environment variables:

SHOPIFY_STOREFRONT=
SHOPIFY_ACCESS_TOKEN=
SHOPIFY_API_VERSION=

Warning

It is strongly recommended that you use the 2024-07 API version or higher. If not, you will not have access to new API features found within this template (this will cause breaking changes).

Development

1. Install dependencies using pnpm install
2. Generate your project types using pnpm codgen
3. Start the development server using pnpm run dev

🏓 Basic Usage

Nitrogen provides a type-safe GraphQL client that seamlessly integrates with Shopify's Storefront API. It uses a server-side proxy to handle API authentication and requests, while exposing a typesafe interface for executing GraphQL operations.

GraphQL Operations

This project includes pre-built GraphQL operations for common Shopify queries and mutations, such as retrieving cart data, localization, and more. All available operations can be found in the operations folder. Feel free to add or remove operations that fit your project needs.

Composable

To get GraphQL operations, use the useShopify composable:

const shopify = useShopify();

Operations can be referenced using this composable with dot notation:

// Shopify
const shopify = useShopify();

// With dot notation
await shopify.cart.addLines(cart.id, [ ... ])
await shopify.product.get({ handle: 'example-product' })

With useAsyncData

Perfect for reactive data fetching in pages or components:

// Shopify
const shopify = useShopify();

// Fetch data
const productVars = computed<ProductQueryVariables>(() => ({
  handle: handle.value,
  country: shopStore.buyerCountryCode,
  language: shopStore.buyerLanguageCode
}))

const { data: productData } = await useAsyncData(
  `product-${handle.value}`,
  () => shopify.product.get(productVars.value),
  { watch: [productVars] }
);

// Computed data
const product = computed(() => productData.value)

With Pinia

Ideal for working with actions in your stores:

// Shopify
const shopify = useShopify();

// Cart actions
actions: {
  async createCart(input?: CartInput, optionalParams?: CartOptionalInput) {
    try {
      const response = await shopify.cart.create({
        input: input,
        ...optionalParams
      });
      
      if (response?.cart) {
        this.cart = response.cart;
      }
    } catch (error) {
      console.error('No cart returned from cartCreate mutation', error);
    }
  },
  // More actions...
}
