Common Workflows

New Next.js Application

Sequence: App Router → Components → Data Fetching

cat ~/.claude/skills/frontend/nextjs-app-router.md          # Setup routing, layouts
cat ~/.claude/skills/frontend/react-component-patterns.md   # Build components
cat ~/.claude/skills/frontend/react-data-fetching.md        # Fetch data

Elegant UI Design

Sequence: Design System → Components → Accessibility

# Note: elegant-design auto-activates as separate Agent Skill
# for design-focused work (shadcn/ui, accessible interfaces, etc.)
cat ~/.claude/skills/frontend/react-component-patterns.md
cat ~/.claude/skills/frontend/web-accessibility.md

Form Implementation

Sequence: Form Handling → State Management

cat ~/.claude/skills/frontend/react-form-handling.md     # Build forms
cat ~/.claude/skills/frontend/react-state-management.md  # Manage form state

Production Optimization

Sequence: Performance → Accessibility → SEO

cat ~/.claude/skills/frontend/frontend-performance.md    # Optimize bundle
cat ~/.claude/skills/frontend/web-accessibility.md       # Ensure accessibility
cat ~/.claude/skills/frontend/nextjs-seo.md              # Optimize SEO

CPU-Intensive Features & PWAs

Sequence: Workers → Concurrency → Performance

cat ~/.claude/skills/frontend/web-workers.md             # Offload heavy computation
cat ~/.claude/skills/frontend/browser-concurrency.md     # Service Workers, offline support
cat ~/.claude/skills/frontend/frontend-performance.md    # Optimize overall performance

React vs Next.js Decision

Use React (Vite) when:

Building SPAs or client-heavy apps
Don't need SSR or SSG
Want full control over routing
Building component libraries

Use Next.js when:

Need SEO (Server-Side Rendering)
Want file-based routing
Need API routes
Building full-stack apps
Want optimal performance out of the box

State Management Decision

Use Component State (useState) when:

State is local to a component
Simple state that doesn't need sharing

Use Context when:

Sharing state across a few components
Theme, auth, or user preferences
Not frequently updated

Use Zustand when:

Need global state
Want simple API
State updates are moderate

Use Redux Toolkit when:

Complex state logic
Need middleware (sagas, thunks)
Large team with established patterns
Time-travel debugging needed

For detailed guidance:

cat ~/.claude/skills/frontend/react-state-management.md

Data Fetching Decision

Server Components (Next.js App Router):

Default choice for Next.js 14+
Fetch on server, zero client JS
Direct database access

Server Actions (Next.js):

For mutations and form handling
Progressive enhancement
Type-safe with TypeScript

SWR:

Client-side data fetching
Built-in caching
Optimistic updates
Focus on user experience

React Query:

Advanced caching strategies
Complex data dependencies
Offline support
DevTools for debugging

For detailed patterns:

cat ~/.claude/skills/frontend/react-data-fetching.md
