NuxtJS Vue TypeScript Development

Guidelines for building Nuxt 3 and Vue 3 applications with TypeScript, Shadcn Vue, Radix Vue, VueUse, and Tailwind.

Code Style and Structure

• Write concise, technical TypeScript with accurate examples
• Employ composition API with declarative patterns; avoid options API
• Favor iteration and modularity over code duplication
• Use descriptive variable names with auxiliary verbs (isLoading, hasError)
• Organize files: exported component, composables, helpers, static content, types
• Keep component boundaries clear — a component should own one piece of UI/behavior; extract composables when logic grows beyond simple template glue

Naming Conventions

• Directories: lowercase with dashes (components/auth-wizard)
• Components: PascalCase (AuthWizard.vue)
• Composables: camelCase (useAuthState.ts)

TypeScript Usage

• Utilize TypeScript throughout; prefer types over interfaces, but use interfaces where you expect a shape to be extended or implemented (e.g. component prop contracts)
• Keep shared types close to the feature that owns them; only promote a type to a shared types/ directory once a second feature needs it
• Avoid enums; use const objects instead
• Leverage Vue 3 with TypeScript, defineComponent, and PropType

Syntax and Formatting

• Use arrow functions for methods and computed properties
• Minimize curly braces in conditionals
• Employ template syntax for declarative rendering

UI and Styling

• Implement Shadcn Vue, Radix Vue, and Tailwind
• Design responsively with mobile-first Tailwind approach
• Keep Tailwind usage accessible and consistent with the project's design system rather than one-off utility soup

Performance

• Leverage Nuxt's built-in optimizations
• Use Suspense for async components
• Implement lazy loading for routes and components
• Optimize images: WebP format, size data, lazy loading
• Review bundle size periodically (nuxi analyze) and use dynamic import() for heavy, rarely-used components

Key Conventions

• VueUse for common composables — reach for them where they simplify reactivity, but avoid ones that hide state transitions you need to reason about explicitly
• Pinia for state management
• Optimize Web Vitals (LCP, CLS, FID)
• Use Nuxt's auto-imports feature

Nuxt-Specific Guidelines

• Follow Nuxt 3 directory structure (pages/, components/, composables/, layouts/, plugins/, server/)
• Leverage auto-imports, file-based routing, server routes, plugins
• Use layouts (layouts/default.vue, <NuxtLayout>) to share page chrome instead of duplicating it per page
• Use server/api/ routes (Nitro) for server-side endpoints, and useRuntimeConfig() for environment-specific config instead of hardcoding values
• Use useFetch and useAsyncData for data fetching
• Implement SEO with useHead and useSeoMeta

Vue 3 Composition API Best Practices

• Use <script setup> syntax
• Leverage ref, reactive, and computed
• Use provide/inject for dependency injection
• Create custom composables for reusable logic
