Skill UI

Presents advanced TypeScript techniques—generics, conditional types, mapped types, discriminated unions, and utility combinations—to help developers build safer, more expressive type systems and runtime guards for complex apps.

Comprehensive guidance for mastering advanced TypeScript type features, including generics, conditional types, mapped types, and utility types. This skill is essential for building robust, maintainable, and highly type-safe applications, such as large-scale libraries, complex API clients, and advanced state management solutions.

This guide provides a quick reference for 'pipe' and 'flow' utilities in fp-ts. The `pipe` function is used to chain multiple operations to transform a specific value, while `flow` allows you to create reusable, composed functions (pipelines). It is essential for implementing clean, declarative data manipulation and functional composition in TypeScript.

A comprehensive quick reference guide for functional programming types in TypeScript using the fp-ts library. It helps users decide which type (`Option`, `Either`, `Task`, etc.) to use based on whether operations are synchronous, asynchronous, and if they involve errors or missing values. It provides decision trees, common import patterns, and utility function patterns for robust TypeScript development.

This guide details migrating outdated and unsafe `as` type assertions in TypeScript test files. It introduces `@total-typescript/shoehorn`, which provides type-safe functions like `fromPartial()` and `fromAny()`. Use this utility when unit tests need to mock large objects or pass only a subset of required data, thereby maintaining strict type checking and improving test robustness. Note: This is strictly for test code.

This utility provides key abstractions for integrating with the webiny administration API using GraphQL. It serves as a centralized catalog, guiding developers on how to correctly import and utilize pre-defined GraphQL client structures. By enforcing standardized interfaces and types, it ensures type safety and consistent data interaction patterns across the application's administrative features, streamlining data fetching in complex admin contexts.

This skill provides a mechanism to execute TypeScript scripts using tsx, enabling fetching and streaming responses from external HTTP endpoints. It is designed for users who need a lightweight Node.js helper utility to manage simple network API calls, making it ideal for rapid integration and data fetching tasks.

This utility manages all types of DNS records (A, CNAME, MX, TXT, etc.) for domains registered with Namecheap via their dedicated API. It guides users through the full setup process, including public IP detection and credential configuration. Users can list domains, view, add, update, or remove records, and manage nameservers and email forwarding rules.

An internal utility designed for deep investigation of JavaScript or TypeScript stack traces. It analyzes complex runtime errors, providing specific checks for asynchronous boundaries, module resolution issues, JSON parsing failures, and type contract violations. It aids developers by generating minimal reproduction commands and identifying potential patch targets for robust error handling.
