Skill UI

This skill provides production-ready architectural patterns for building robust mobile applications using React Native and Expo. It covers complex topics like state management, sophisticated navigation flow, integrating native modules, and implementing offline-first capabilities. It is ideal for starting new projects or optimizing existing large-scale React Native applications.

Builds and optimizes production-ready React Native and Expo mobile apps, covering navigation hierarchies, native module setup, FlatList performance tuning, SafeArea/keyboard handling, and multi-platform testing to ensure smooth iOS and Android releases.

This comprehensive workflow guides the development of modern, scalable full-stack applications using Next.js 14+, React, and TypeScript. It covers all phases, from project setup and component architecture to advanced data fetching (Server Components, React Query), styling with Tailwind CSS, robust testing (E2E via Playwright), and deployment optimization. Ideal for building complex, production-grade web interfaces.

Highlights React 19 idioms such as the new use() hook, server components, server actions, optimistic updates, suspense, error handling, and compound hooks to structure Next.js apps with streaming data, interactivity, and reusable hooks.

A comprehensive guide to modern React state management patterns. It covers various state types—including local, global, server, and form state—and demonstrates best practices using industry-leading libraries like Redux Toolkit, Zustand, Jotai, and React Query. Use this when building complex, scalable React applications and needing to select the optimal state solution.

A comprehensive guide to modern React UI patterns. It covers best practices for managing application states, including determining when to use skeleton loaders vs. spinners, implementing robust error handling hierarchies (inline, toast, banner), and designing effective empty states. Essential for building high-quality, user-friendly components that handle asynchronous data gracefully.

Summarizes React’s official guidance on when to use or avoid useEffect by highlighting derived state handling, expensive calculations, subscriptions, and cleanup strategies for data fetching.

Automates building Redux slices, guiding best practices, producing production-ready code, and validating frontend state management patterns for React and Vue projects.

This guide provides comprehensive best practices for creating high-quality videos using Remotion within a React environment. It covers advanced techniques for dynamic content generation, including integrating 3D models (Three.js), managing diverse assets like audio, video, and fonts, implementing complex animations, data visualization, and generating precise captions. Use this skill when developing professional, robust video generation workflows in React.

This guide provides comprehensive instruction on integrating with the full Replit ecosystem. Learn to monitor deployment lifecycles, set up external webhook receivers (e.g., GitHub, Stripe), build custom workspace extensions using React/TypeScript, and create complex automated workflows using Replit Agents. Essential for building scalable, event-driven applications on Replit.

Provides automated guidance for setting up responsive breakpoint analysis, follows frontend best practices, validates configurations, and supports React/Vue/CSS accessibility and performance scenarios.

This guide provides expert patterns for building robust and scalable applications on the Salesforce platform. It covers modern UI development using Lightning Web Components (LWC) with reactive data services, and teaches advanced Apex implementation. Key patterns include utilizing handler classes for bulkified triggers to prevent recursion and ensuring separation of concerns, crucial for high-performance, maintainable code.
