vue-best-practices

vue-best-practices is a skill for Claude Code, Codex from FrontToEnd/agent-skills. It costs 64 tokens per session (935 once invoked), scanned A, original, MIT.

A set of performance guidelines for Vue 3 and Nuxt, JavaScript frameworks for building web interfaces and applications. The rules cover data loading, application bundles, server work, reactivity, and rendering.

In plain words
What is it for?
Use it when writing, reviewing, or refactoring Vue components, Nuxt pages, data fetching, bundle configuration, or rendering logic.
Why use it?
It helps developers spot patterns that make pages load slowly, send too much code, or perform unnecessary work in the browser or server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

vue-best-practices scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Vue Best Practices

Overview

Comprehensive performance optimization guide for Vue 3 and Nuxt applications, containing 40+ rules across 8 categories. Rules are prioritized by impact to guide automated refactoring and code generation.

When to Apply

Reference these guidelines when:

  • Writing new Vue 3 components or Nuxt pages
  • Implementing data fetching (client or server-side)
  • Reviewing code for performance issues
  • Refactoring existing Vue/Nuxt code
  • Optimizing bundle size or load times

Priority-Ordered Guidelines

Rules are prioritized by impact:

Priority Category Impact
1 Eliminating Waterfalls CRITICAL
2 Bundle Size Optimization CRITICAL
3 Server-Side Performance HIGH
4 Reactivity Optimization MEDIUM-HIGH
5 Re-render Optimization MEDIUM
6 Rendering Performance MEDIUM
7 JavaScript Performance LOW-MEDIUM
8 Advanced Patterns LOW

Quick Reference

Critical Patterns (Apply First)

Eliminate Waterfalls:

  • Defer await until needed (move into branches)
  • Use Promise.all() for independent async operations
  • Start promises early, await late
  • Use Nuxt useAsyncData with lazy option for parallel fetching
  • Use <Suspense> boundaries to stream content

Reduce Bundle Size:

  • Avoid barrel file imports (import directly from source)
  • Use defineAsyncComponent for heavy components
  • Defer non-critical third-party libraries
  • Use Vite's dynamic import for code splitting
  • Consider petite-vue for progressive enhancement

High-Impact Server Patterns

  • Avoid cross-request state pollution in SSR
  • Create new app instance per request
  • Use Pinia with SSR-safe patterns
  • Parallelize data fetching with component composition
  • Minimize serialization at SSR boundaries

Medium-Impact Reactivity Patterns

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
