Nuxt Best Practices

Comprehensive performance optimization guide for Nuxt 4 applications (current: Nuxt 4.5, with notes for 3.x apps approaching EOL). Contains 23 rules across 9 categories, prioritized by impact to guide automated refactoring and code generation.

When to Apply

Reference these guidelines when:

• Writing new Nuxt pages, components, or composables
• Implementing data fetching (useFetch, useAsyncData, the 4.5 enabled option)
• Creating server routes and API endpoints
• Organizing types, composables, and auto-imports
• Working with Nuxt modules and plugins
• Configuring rendering modes (SSR, SSG, SPA, 4.5 experimental SSR streaming)
• Using layouts, named views, and NuxtLink prefetching (Nuxt 4.5 conventions)
