This repository provides a collection of shared configurations and tools for web development at Shopify. It is structured as a monorepo containing multiple npm packages, including ESLint and Stylelint plugins with custom rules, Babel presets, TypeScript configurations, Prettier settings, and utilities for image optimization. The project enforces consistent coding standards across Shopify's web applications and is used in their build and development pipelines. The architecture is modular, with each package providing a specific tool or configuration that can be extended by consumers.
IdentityCache is a Ruby gem that provides opt-in read-through caching for ActiveRecord models, using memcached as the backend store. It allows developers to declare cache indexes on model attributes and associations, and automatically handles cache invalidation via after_commit hooks. The library supports embedded and reference-based caching for associations, secondary indexes, attribute caching, and batch fetching. It includes advanced features like fill locks to mitigate thundering herd problems, memoization per request, and deferred expiration. The codebase is well-structured with clear separation of concerns, extensive test coverage, and production use at Shopify.
This repository is a starter theme for building headless ecommerce storefronts with Shopify using Astro. It provides a server-rendered Astro application with Svelte islands for interactive components like the cart drawer and add-to-cart form. The application fetches product data from the Shopify Storefront GraphQL API, displays product listings and detail pages, and manages a shopping cart with persistent state via nanostores. It is configured for deployment on Vercel and uses Tailwind CSS for styling. The architecture is a monolithic web application with clear separation of concerns: `src/utils` contains the Shopify API client, GraphQL queries, Zod schemas for runtime validation, and configuration; `src/stores` manages cart state; `src/components` contains Astro and Svelte components for UI. The Shopify client (`src/utils/shopify.ts`) intelligently switches between public and private access tokens based on server/client rendering and includes buyer IP forwarding for accurate pricing. The codebase demonstrates modern practices: TypeScript strict mode, Zod validation of external API responses, Svelte 5 runes, and responsive image generation with srcset. While the theme includes demo content (hardcoded reviews, accordions) and a hardcoded API version (2023-01), the core utilities are well-crafted and reusable. The Shopify API client and image component can be extracted into other projects with minimal changes. Overall, this is a solid, professional-grade starter theme that showcases a clean integration between Astro, Svelte, and Shopify.
This is the Builder.io monorepo, a comprehensive headless CMS and visual page builder platform. It provides multi-framework SDKs (React, Angular, Vue, Svelte, Qwik, Solid, React Native, etc.) for fetching and rendering Builder.io content, a plugin ecosystem for extending the visual editor with custom components and data sources (commerce, CMS, media), CLI tools for project scaffolding and space management, and numerous example applications. The core SDK uses Mitosis for code generation to produce framework-specific implementations, and includes features like A/B testing, personalization, localization, visual editing, and server-side rendering. The repository also contains a Gatsby source plugin, a plugin loader, and integration plugins for Shopify, Contentful, Cloudinary, and others. While the codebase is large and actively maintained, it exhibits some technical drift with legacy Gen1 SDKs, duplicated configurations, and outdated dependencies in examples.
