Shopify 开发技能

当用户询问以下内容时使用此技能：

构建 Shopify 应用或扩展
创建结账/管理后台/POS 界面自定义
使用 Liquid 模板开发主题
与 Shopify GraphQL 或 REST API 集成

GraphQL 模式（已针对 API 2026-01 验证）

query GetProducts($first: Int!, $query: String) {
  products(first: $first, query: $query) {
    edges {

{% comment %} 产品卡片片段 {% endcomment %}

    {% if product.compare_at_price > product.price %}
      <p class="sale-badge">Sale</p>
    {% endif %}
  </a>
</div>

在 shopify.app.toml 中：

[webhooks]
api_version = "2026-01"

[[webhooks.subscriptions]]
topics = ["orders/create", "orders/updated"]
uri = "/webhooks/orders"

[[webhooks.subscriptions]]
topics = ["products/update"]
uri = "/webhooks/products"

# GDPR 强制要求的 webhook（应用审核必需）
[webhooks.privacy_compliance]
customer_data_request_url = "/webhooks/gdpr/data-request"
customer_deletion_url = "/webhooks/gdpr/customer-deletion"
shop_deletion_url = "/webhooks/gdpr/shop-deletion"

新开发优先使用 GraphQL 而非 REST
仅请求需要的字段（降低查询成本）
使用 pageInfo.endCursor 实现基于游标的分页
处理超过 250 个项目时使用批量操作
使用指数退避处理速率限制

将 API 凭证存储在环境变量中
处理前始终验证 webhook HMAC 签名
验证 OAuth state 参数以防止 CSRF
请求最小必要的访问权限范围
对于嵌入式应用使用会话令牌

当数据不频繁变化时缓存 API 响应
在扩展中使用懒加载
使用 img_url 过滤器优化主题中的图片
通过响应头监控 GraphQL 查询成本

如果看到速率限制错误： → 实现指数退避重试逻辑 → 对于大型数据集切换到批量操作 → 监控 X-Shopify-Shop-Api-Call-Limit 响应头

如果身份验证失败： → 验证访问令牌是否仍然有效 → 检查是否已授予所有必需的权限范围 → 确保 OAuth 流程已成功完成

如果扩展未显示： → 验证扩展目标是否正确 → 检查扩展是否已通过 shopify app deploy 发布 → 确认应用已安装在测试店铺上

如果 webhook 未接收到事件： → 验证 webhook URL 是否可公开访问 → 检查 HMAC 签名验证逻辑 → 在合作伙伴仪表板中查看 webhook 日志

如果 GraphQL 查询失败： → 根据模式验证查询（使用 GraphiQL 浏览器） → 检查错误消息中是否有已弃用的字段 → 验证您是否拥有必需的访问权限范围

Shopify Development Skill

Use this skill when the user asks about:

Building Shopify apps or extensions
Creating checkout/admin/POS UI customizations
Developing themes with Liquid templating
Integrating with Shopify GraphQL or REST APIs
Implementing webhooks or billing
Working with metafields or Shopify Functions

ROUTING: What to Build

IF user wants to integrate external services OR build merchant tools OR charge for features: → Build an App (see references/app-development.md)

IF user wants to customize checkout OR add admin UI OR create POS actions OR implement discount rules: → Build an Extension (see references/extensions.md)

IF user wants to customize storefront design OR modify product/collection pages: → Build a Theme (see references/themes.md)

IF user needs both backend logic AND storefront UI: → Build App + Theme Extension combination

Shopify CLI Commands

Install CLI:

npm install -g @shopify/cli@latest

Create and run app:

shopify app init          # Create new app
shopify app dev           # Start dev server with tunnel
shopify app deploy        # Build and upload to Shopify

Generate extension:

shopify app generate extension --type checkout_ui_extension
shopify app generate extension --type admin_action
shopify app generate extension --type admin_block
shopify app generate extension --type pos_ui_extension
shopify app generate extension --type function

Theme development:

shopify theme init        # Create new theme
shopify theme dev         # Start local preview at localhost:9292
shopify theme pull --live # Pull live theme
shopify theme push --development  # Push to dev theme

Access Scopes

Configure in shopify.app.toml:

[access_scopes]
scopes = "read_products,write_products,read_orders,write_orders,read_customers"

Common scopes:

read_products, write_products - Product catalog access
read_orders, write_orders - Order management
read_customers, write_customers - Customer data
read_inventory, write_inventory - Stock levels
read_fulfillments, write_fulfillments - Order fulfillment

GraphQL Patterns (Validated against API 2026-01)

Query Products

query GetProducts($first: Int!, $query: String) {
  products(first: $first, query: $query) {
    edges {
      node {
        id
        title
        handle
        status
        variants(first: 5) {
          edges {
            node {
              id
              price
              inventoryQuantity
            }
          }
        }
      }
    }
    pageInfo {
      hasNextPage
      endCursor
    }
  }
}

Query Orders

query GetOrders($first: Int!) {
  orders(first: $first) {
    edges {
      node {
        id
        name
        createdAt
        displayFinancialStatus
        totalPriceSet {
          shopMoney {
            amount
            currencyCode
          }
        }
      }
    }
  }
}

Set Metafields

mutation SetMetafields($metafields: [MetafieldsSetInput!]!) {
  metafieldsSet(metafields: $metafields) {
    metafields {
      id
      namespace
      key
      value
    }
    userErrors {
      field
      message
    }
  }
}

Variables example:

{
  "metafields": [
    {
      "ownerId": "gid://shopify/Product/123",
      "namespace": "custom",
      "key": "care_instructions",
      "value": "Handle with care",
      "type": "single_line_text_field"
    }
  ]
}

Checkout Extension Example

import {
  reactExtension,
  BlockStack,
  TextField,
  Checkbox,
  useApplyAttributeChange,
} from "@shopify/ui-extensions-react/checkout";

export default reactExtension("purchase.checkout.block.render", () => (
  <GiftMessage />
));

function GiftMessage() {
  const [isGift, setIsGift] = useState(false);
  const [message, setMessage] = useState("");
  const applyAttributeChange = useApplyAttributeChange();

  useEffect(() => {
    if (isGift && message) {
      applyAttributeChange({
        type: "updateAttribute",
        key: "gift_message",
        value: message,
      });
    }
  }, [isGift, message]);

  return (
    <BlockStack spacing="loose">
      <Checkbox checked={isGift} onChange={setIsGift}>
        This is a gift
      </Checkbox>
      {isGift && (
        <TextField
          label="Gift Message"
          value={message}
          onChange={setMessage}
          multiline={3}
        />
      )}
    </BlockStack>
  );
}

Liquid Template Example

{% comment %} Product Card Snippet {% endcomment %}
<div class="product-card">
  <a href="{{ product.url }}">
    {% if product.featured_image %}
      <img
        src="{{ product.featured_image | img_url: 'medium' }}"
        alt="{{ product.title | escape }}"
        loading="lazy"
      >
    {% endif %}
    <h3>{{ product.title }}</h3>
    <p class="price">{{ product.price | money }}</p>
    {% if product.compare_at_price > product.price %}
      <p class="sale-badge">Sale</p>
    {% endif %}
  </a>
</div>

Webhook Configuration

In shopify.app.toml:

[webhooks]
api_version = "2026-01"

[[webhooks.subscriptions]]
topics = ["orders/create", "orders/updated"]
uri = "/webhooks/orders"

[[webhooks.subscriptions]]
topics = ["products/update"]
uri = "/webhooks/products"

# GDPR mandatory webhooks (required for app approval)
[webhooks.privacy_compliance]
customer_data_request_url = "/webhooks/gdpr/data-request"
customer_deletion_url = "/webhooks/gdpr/customer-deletion"
shop_deletion_url = "/webhooks/gdpr/shop-deletion"

Best Practices

API Usage

Use GraphQL over REST for new development
Request only fields you need (reduces query cost)
Implement cursor-based pagination with pageInfo.endCursor
Use bulk operations for processing more than 250 items
Handle rate limits with exponential backoff

Security

Store API credentials in environment variables
Always verify webhook HMAC signatures before processing
Validate OAuth state parameter to prevent CSRF
Request minimal access scopes
Use session tokens for embedded apps

Performance

Cache API responses when data doesn't change frequently
Use lazy loading in extensions
Optimize images in themes using img_url filter
Monitor GraphQL query costs via response headers

Troubleshooting

IF you see rate limit errors: → Implement exponential backoff retry logic → Switch to bulk operations for large datasets → Monitor X-Shopify-Shop-Api-Call-Limit header

IF authentication fails: → Verify the access token is still valid → Check that all required scopes were granted → Ensure OAuth flow completed successfully

IF extension is not appearing: → Verify the extension target is correct → Check that extension is published via shopify app deploy → Confirm the app is installed on the test store

IF webhook is not receiving events: → Verify the webhook URL is publicly accessible → Check HMAC signature validation logic → Review webhook logs in Partner Dashboard

IF GraphQL query fails: → Validate query against schema (use GraphiQL explorer) → Check for deprecated fields in error message → Verify you have required access scopes
