Skill UI

Learn how to build advanced, server-side business logic for Shopify using Shopify Functions and WebAssembly (WASM). This guide covers implementing custom discount rules, payment customizations, delivery option filtering, and cart transformations directly at the checkout. Designed for developers, it leverages the WASM sandbox for highly constrained, powerful e-commerce functionality.

Provides a comprehensive, layered reference architecture for building production-grade integrations with Webflow's Data API v2. This guide separates concerns into distinct layers: API access, business logic (CMS, e-commerce), webhook handling, and caching, ensuring scalability and maintainability for complex web applications.

This guide outlines robust architectural patterns for building complex administrative extensions within a React environment. It enforces strict separation of concerns by dividing logic into two main layers: Headless Features (business logic, using UseCase/Repository/Gateway) and Presentation Features (UI components, Presenters, and hooks). Following these patterns ensures highly maintainable, testable, and scalable codebases, promoting clean architecture principles for web applications.

This API abstraction catalog provides formalized interfaces for core business logic within the webiny API. It defines standard architectural patterns—including Use Cases, Repositories, and Event Handlers—for managing the complete folder lifecycle. It covers CRUD operations, permission control (FLP), hierarchy resolution, and complex business rules, ensuring a clean separation of concerns and robust code implementation.

A comprehensive API catalog providing robust abstractions for managing files. It includes core repositories and use cases for CRUD operations (Create, Read, Update, Delete), along with detailed event handlers (before/after hooks) to manage the entire file lifecycle. Essential for building scalable and maintainable backend systems that handle file storage and business logic.

This pattern provides a robust method for extending and customizing existing GraphQL APIs. Developers can implement `GraphQLSchemaFactory` to add custom root queries and mutations, injecting complex business logic and use cases directly into the API layer. It fully supports per-resolver dependency injection (DI), ensuring that every resolver has access to critical request-scoped context, such as identity and tenancy, making it ideal for building modular, enterprise-grade backend services.

This pattern provides a comprehensive guide to implementing domain event handlers (before/after hooks) within the Webiny framework. It emphasizes the 'thin orchestrator' principle, requiring handlers to delegate all business logic to reusable service abstractions or UseCases for maximum reusability. Furthermore, it details the process of defining, publishing, and reacting to custom domain events, ensuring a clean, decoupled architecture.

This skill provides a robust mechanism for extending an existing API gateway by adding custom, non-GraphQL HTTP endpoints (GET, POST, PUT, etc.). Developers can implement the Route.Interface and register it using the <Api.Route> component. It supports full Dependency Injection (DI), providing framework-agnostic Request and Reply objects, making it ideal for integrating complex business logic directly into the API structure.

This guide details the UseCase pattern, an architectural pattern used to encapsulate specific business operations within the Webiny framework. Learn how to define UseCases as injectable dependencies, manage input and output using the structured Result<T, E> type, and implement robust, domain-specific error handling. Mastering this pattern is crucial for building highly modular, testable, and maintainable backend APIs.

This tool analyzes and refactors code to detect and correct anemic domain models. It enforces rich domain modeling patterns (Entities, Value Objects, Aggregates, Domain Events), improving encapsulation and business logic ownership. Use it when validating, reviewing, or refactoring core domain logic to ensure adherence to Domain-Driven Design (DDD) principles.

Logic Lens is an advanced AI skill that performs deep, formal logic-driven code review. Unlike standard linters, it analyzes code for complex issues like race conditions, security vulnerabilities (SQL injection, XSS), type safety flaws, and algorithmic errors across 9 critical risk categories. It is ideal for pre-merge PR reviews, auditing sensitive code paths, and refactoring complex business logic.

This router guides the testing of systemic flaws in business processes and state machines. It is essential when vulnerabilities stem from workflow abuse, race conditions, pricing flaws, or multi-step state attacks, rather than simple input sanitation issues. Use it to test complex business flows like payments, inventory management, and approval sequences.
