skills

Teaches the command pattern for decoupling task execution from invocation. Use when you need undo/redo functionality, queued operations, or want to decouple the object that invokes an operation from the one that performs it.

Teaches the proxy pattern for intercepting object operations. Use when you need validation, logging, formatting, or access control on property access, assignment, or function invocation.

Teaches the Higher-Order Component (HOC) pattern for logic reuse. Use when you need to share cross-cutting concerns like authentication, logging, or data fetching across multiple components.

Teaches server-side rendering (SSR) for React applications. Use when you need faster initial page loads, better SEO, or dynamic per-request HTML generation.

Teaches Vue state management with stores, Pinia, and the Composition API. Use when you need to share and synchronize state across multiple components beyond what props and events can handle.

Teaches JavaScript compression techniques including Gzip and Brotli. Use when optimizing network transfer times or configuring server-side compression for production builds.

Teaches dynamic import() for on-demand code loading. Use when you need to reduce initial bundle size by lazily loading modules that aren't required at startup.

Teaches interaction-based lazy loading for non-critical resources. Use when you have heavy components or libraries that are only needed after user interaction like clicks, hovers, or form input.

Teaches the islands architecture pattern for partial hydration. Use when building content-heavy sites where most of the page is static and only small regions need interactivity.

Provides framework-agnostic JavaScript runtime performance patterns. Use when optimizing hot paths, loops, DOM operations, caching, or data structure choices in performance-critical code.

Teaches resource loading sequence optimization for Core Web Vitals. Use when you need to improve FCP, LCP, or FID by reordering how critical resources are discovered and loaded.

Teaches the mediator pattern for centralized component communication. Use when multiple components need to communicate and direct coupling between them creates complexity or tight dependencies.

Teaches the module pattern for code organization and encapsulation. Use when structuring JavaScript into reusable, maintainable pieces with clear public and private boundaries.

Teaches the observer pattern for event-driven communication. Use when you need decoupled publish/subscribe behavior where multiple parts of your system react to state changes or events.

Teaches resource preloading to prioritize critical assets. Use when critical resources like fonts, hero images, or key scripts are discovered late in the loading waterfall.

Teaches the provider pattern for sharing data across component trees. Use when multiple nested components need access to the same data and prop drilling becomes unwieldy.

Teaches the singleton pattern for managing a single shared instance. Use when exactly one instance of a class or object is needed to coordinate actions across your application.

Teaches strategies for mitigating third-party script performance impact. Use when third-party scripts like analytics, ads, or widgets are degrading your page load times or Core Web Vitals.

Teaches the View Transitions API for animating DOM changes. Use when you want smooth animated transitions between pages or UI states without manual animation code.

Teaches virtual list (windowing) techniques for rendering large datasets. Use when rendering lists or tables with hundreds or thousands of items that cause scroll jank or slow initial render.

Teaches Vite-specific bundle optimization patterns. Use when configuring Vite builds, code splitting, managing dependencies, or troubleshooting slow Vite builds.

Teaches design patterns for building AI-powered React interfaces. Use when creating chatbots, intelligent assistants, streaming UIs, or any AI-driven user experience in React.

Teaches client-side rendering (CSR) for React applications. Use when building highly interactive apps where SEO is not a priority and the UI is driven by user actions.

Teaches the compound component pattern for shared implicit state. Use when building related components like tabs, accordions, or dropdowns that need to coordinate without explicit prop passing.

Teaches React Hooks for reusing stateful logic across components. Use when extracting shared behavior like form handling, subscriptions, or side effects into reusable custom hooks.

Teaches Incremental Static Regeneration (ISR) for updating static content post-build. Use when you have static pages that need periodic updates without a full site rebuild.

Teaches the presentational/container pattern for separating view and logic. Use when you want to isolate data fetching and business logic from UI rendering for better testability and reuse.

Teaches progressive hydration for prioritized client-side interactivity. Use when server-rendered pages have non-critical sections whose JavaScript can be deferred to improve Time to Interactive.

Provides a comprehensive guide to the modern React 2026 stack. Use when starting a new React project or modernizing an existing one with current frameworks, build tools, routing, state management, or AI integration.

Teaches modern React composition patterns for 2025/2026. Use when designing component APIs, building shared UI libraries, or refactoring prop-heavy components.

Teaches modern React data fetching patterns with TanStack Query, SWR, and Suspense. Use when implementing caching, deduplication, optimistic updates, or parallel loading in React applications.

Teaches React rendering performance optimization patterns. Use when reducing unnecessary re-renders, optimizing memoization, improving state design, or diagnosing React performance issues.

Teaches selective hydration combined with streaming SSR in React 18+. Use when you need to prioritize hydrating interactive components while streaming the rest of the page.

Teaches React Server Components for zero-bundle server rendering. Use when components only need server-side data access and don't require client-side interactivity like state or event handlers.

Teaches the render props pattern for flexible component composition. Use when you need to share rendering logic between components by passing a function that returns JSX as a prop.

Teaches static rendering (SSG) for build-time HTML generation. Use when your pages don't change per request and can be pre-rendered at build time for maximum cacheability and performance.

Teaches async component loading in Vue for performance optimization. Use when you have heavy components that aren't needed on initial render and can be loaded on demand.

Teaches Vue component fundamentals including markup, logic, and styles. Use when building or structuring Vue single-file components as the foundational building blocks of your application.

Teaches the container/presentational pattern for Vue components. Use when you want to separate data fetching and business logic from presentation for better testability and reuse.

Teaches the data provider pattern using renderless components and scoped slots. Use when you need to abstract data fetching or state management logic and expose it to child components via slots.
