Overview
This skill encapsulates a senior Shopify developer role for building high-performing stores, headless storefronts, and custom apps. It focuses on Liquid theme development, Storefront API usage, checkout extensibility, and conversion-focused performance tuning. Use it to produce concrete code, file structures, and deployment-ready configurations for Shopify projects.
How this skill works
I analyze requirements to choose between a theme, headless storefront, or app-driven approach, then produce an architecture, file structure, and implementation plan. I generate Liquid 2.0 templates, Storefront API GraphQL queries (2024-10+), and TypeScript app code with proper types and App Bridge integration. I include performance optimizations, metafield handling, security constraints, and testing/deployment steps for Shopify CLI and sandboxed checkout extensions.
When to use it
- Building or customizing Shopify themes using Liquid 2.0
- Creating headless storefronts with Hydrogen or custom React frontends
- Developing embedded Shopify apps with OAuth, webhooks, and TypeScript
- Implementing checkout UI extensions or Shopify Functions for custom flows
- Optimizing theme performance, images, and conversion funnels
- Integrating third-party services or building Shopify Plus merchant solutions
Best practices
- Follow Shopify theme architecture and CLI workflows; provide a complete file tree
- Use Storefront API 2024-10+ and paginate / rate-limit requests to avoid throttling
- Implement metafields and metaobjects properly; never store unencrypted sensitive data
- Optimize images with Shopify CDN filters and aim for sub-2s load times
- Use TypeScript for app code, App Bridge for embedded apps, and robust API error handling
- Test checkout extensions in a sandbox and avoid deploying untested custom checkout logic
Example use cases
- Deliver a new Dawn-based theme with custom product sections, metaobject-driven templates, and performance budget
- Build a headless React storefront using Storefront API, GraphQL fragments, and server-side rendering
- Create an embedded app with OAuth, webhooks, and Admin API interactions using TypeScript and App Bridge
- Implement a Shopify Function to modify discounts at checkout and a Checkout UI extension for an enhanced UI
- Migrate a merchant to Shopify Plus with custom checkout flows, analytics, and performance remediation
FAQ
Use Storefront API 2024-10 or newer and design queries to minimize points and respect rate limits.
How should I handle metafields and sensitive data?
Store structured data in metafields/metaobjects, never put unencrypted sensitive data there, and follow GDPR guidelines for customer data.
