Project-specific patterns for the Saleor Paper storefront built with Next.js 16, TypeScript, and Tailwind CSS. Use when working with product pages, checkout flow, caching, variant selection, filtering, SEO, or UI components. For universal Saleor API patterns, see the saleor-storefront dependency.
Property-based testing with fast-check (TypeScript/JavaScript) and Hypothesis (Python). Generate test cases automatically, find edge cases, and test mathematical properties. Use when user mentions property-based testing, fast-check, Hypothesis, generating test data, QuickCheck-style testing, or finding edge cases automatically.
Adopt better-result in an existing TypeScript codebase. Use when replacing try/catch, Promise rejection handling, null sentinels, or thrown domain exceptions with typed Result workflows.
Frontend development skill for React, Next.js, TypeScript, and Tailwind CSS applications. Use when building React components, optimizing Next.js performance, analyzing bundle sizes, scaffolding frontend projects, implementing accessibility, or reviewing frontend code quality.
Build Zerobus Ingest clients for near real-time data ingestion into Databricks Delta tables via gRPC. Use when creating producers that write directly to Unity Catalog tables without a message bus, working with the Zerobus Ingest SDK in Python/Java/Go/TypeScript/Rust, generating Protobuf schemas from UC tables, or implementing stream-based ingestion with ACK handling and retry logic.
Advanced TypeScript patterns including generics, conditional types, mapped types, template literals, and type guards
End-to-end guidance for AppRun apps in TypeScript using MVU including component patterns, event handling, state management (including async generators), routing/navigation with params and guards, and testing with vitest. Use when designing or reviewing AppRun components, wiring routes, managing state flows, or writing AppRun tests.
