# Custom data

Storefront Web Components can be used to display custom data stored in metafields and metaobjects from your Shopify store. This guide covers some of the most common ways to use custom data, and includes ready-to-use examples that you can adapt to your own storefront.

***

## Setup

Although Storefront Web Components don't require an access token for most use cases, you need to provide a Storefront API access token to fetch metafields and metaobjects.

To set up a Storefront API access token:

1. Install either the [Hydrogen](https://apps.shopify.com/hydrogen) or [Headless](https://apps.shopify.com/headless) sales channel in your Shopify admin.

2. Create a new storefront within the sales channel.

3. Copy your public access token from your storefront settings:

   * **Hydrogen**: Navigate to **Storefront settings** and find the public access token in the **Storefront API** section.
   * **Headless**: Inside the **Manage API access** section of your storefront, click on the **Manage** button for the Storefront API to find the public access token.

4. Make sure that access is enabled for metaobjects in the **Permissions** section.

5. In your Storefront Web Components code, add the public access token to the `public-access-token` attribute of your [`shopify-store` component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-store).

### Examples

* ####

  ##### Add a store component

  ```html
  <!-- The public-access-token is required
   for access to metafields and metaobjects -->
  <shopify-store
    public-access-token="your-access-token"
    store-domain="your-store-domain"
  ></shopify-store>
  ```

## Render a metafield

To display a product's metafield data on your storefront:

1. Create a [`shopify-context` component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-context) that targets your specific product.
2. Inside the product context, add another `shopify-context` component that targets the metafield. Specify the metafield's namespace and key as attributes. You can find the namespace and key in the [**Metafields and metaobjects**](https://www.shopify.com/admin/settings/custom_data) settings in your Shopify admin.
3. Within the metafield context, use a [`shopify-data` component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-data) to display the metafield's value on the page.

  ##### Render a product metafield

  ```html
  <!-- The public-access-token is required
   for access to metafields and metaobjects -->
   <shopify-store
   public-access-token="your-access-token"
   store-domain="your-store-domain"
  ></shopify-store>

  <shopify-context
   type="product"
   handle="your-product-handle"
  >
   <template>
     <shopify-context
       type="metafield"
       query="product.metafield"
       key="your-metafield-key"
       namespace="your-metafield-namespace"
     >
       <template>
         <shopify-data
           query="metafield.value"
         ></shopify-data>
       </template>
     </shopify-context>
   </template>
  </shopify-context>
  ```

## Metafield references

You can use a metafield to reference other objects in your store. For example, you can use a metafield on a product to reference another product. To render a metafield reference:

1. Create a [`shopify-context` component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-context) that targets your specific product.
2. Inside the product context, add another `shopify-context` component that targets the metafield. Specify the metafield's namespace and key as attributes. You can find the namespace and key in the [**Metafields and metaobjects**](https://www.shopify.com/admin/settings/custom_data) settings in your Shopify admin.
3. Within the metafield context, add another `shopify-context` component that targets the reference.
4. Within the reference context, use a [`shopify-data` component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-data) to display the reference's value on the page.

  ##### Render a metafield reference

  ```html
  <!-- The public-access-token is required
   for access to metafields and metaobjects -->
   <shopify-store
   public-access-token="your-access-token"
   store-domain="your-store-domain"
  ></shopify-store>

  <!-- A context for the product -->
  <shopify-context
   type="product"
   handle="your-product-handle"
  >
   <template>
     <!-- A context for the metafield -->
     <shopify-context
       type="metafield"
       query="product.metafield"
       key="your-metafield-key"
       namespace="your-metafield-namespace"
     >
       <template>
         <!-- A context for the product
          that the metafield references -->
         <shopify-context
           type="product"
           query="metafield.reference"
         >
           <template>
             <div>
               <shopify-data
                 query="product.title"
               ></shopify-data>
             </div>
           </template>
         </shopify-context>
       </template>
     </shopify-context>
   </template>
  </shopify-context>
  ```

## Render a metaobject

Metaobjects are dynamic objects that store custom data in your Shopify store. You can render metaobjects using Storefront Web Components with a [shopify-context component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-context):

1. Create a `shopify-context` component with `type="metaobject"` and `handle` attributes. The `handle` attribute specifies which metaobject to render. You can find the handle values for each metaobject on the [**Entries**](https://www.shopify.com/admin/content/metaobjects/entries) page in your Shopify admin.
2. Add a `metaobject-definition-type` attribute to the same `shopify-context` component to specify the metaobject definition type.
3. To access metafields within the metaobject, add a nested [`shopify-context` component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-context) with `type="field"` and `key` attributes. The `key` attribute identifies which metafield to target. You can find the key values for each metafield in the [**Metafields and metaobjects**](https://www.shopify.com/admin/settings/custom_data) settings in your Shopify admin.
4. Inside the metafield context, add your template and components to display the metafield data.

  ##### Render a metaobject

  ```html
  <!-- The public-access-token is required
   for access to metafields and metaobjects -->
   <shopify-store
   public-access-token="your-access-token"
   store-domain="your-store-domain"
  ></shopify-store>

  <!-- A context for the metaobject. It must contain
   a metaobject attribute with the metaobject name -->
  <shopify-context
   type="metaobject"
   handle="your-metaobject-handle"
   metaobject-definition-type="your-metaobject-definition-type"
  >
   <template>
     <!-- A context for the metafield.
      It must contain the metafield key -->
     <shopify-context
       type="field"
       query="metaobject.field"
       key="your-metafield-key"
     >
       <template>
         <div>
           <shopify-data
             query="field.value"
           ></shopify-data>
         </div>
       </template>
     </shopify-context>
   </template>
  </shopify-context>
  ```

## Custom components

Metafields support various data types, including rich text, links, numbers, dates, JSON, and file references. The [`shopify-data` component](https://shopify.dev/docs/api/storefront-web-components/components/shopify-data) displays the raw metafield value as-is. For more sophisticated presentations of complex data types like JSON objects or structured content, you can build custom components that receive the metafield value as an attribute with the [`shopify-attr` attribute](https://shopify.dev/docs/api/storefront-web-components/attributes/shopify-attr).

### Examples

* ####

  ##### Add a custom component

  ```html
  <script>
    // Define a custom component that renders a JSON object
    class CustomComponent extends HTMLElement {
      constructor() {
        super();
      }
      connectedCallback() {
        const value = JSON.parse(
          this.getAttribute("value"),
        );
        this.innerHTML = `
          <div>
            <h1>${value.title}</h1>
            <p>${value.description}</p>
          </div>
        `;
      }
    }

    // Register the custom component
    customElements.define(
      "custom-component",
      CustomComponent,
    );
  </script>

  <!-- The public-access-token is required
    for access to metafields and metaobjects -->
  <shopify-store
    public-access-token="your-access-token"
    store-domain="your-store-domain"
  ></shopify-store>

  <shopify-context
    type="product"
    handle="your-product-handle"
  >
    <template>
      <shopify-context
        type="metafield"
        query="product.metafield"
        key="your-metafield-key"
        namespace="your-metafield-namespace"
      >
        <template>
          <!-- Bind the metafield value to the
          value attribute of the custom component -->
          <custom-component
            shopify-attr--value="metafield.value"
          ></custom-component>
        </template>
      </shopify-context>
    </template>
  </shopify-context>
  ```
