vue

A set of coding rules for Vue.js, a JavaScript framework for building web interfaces. It covers components, the Composition API, state management, routing, forms, and performance.

In plain words
What is it for?
Guiding the structure and implementation of Vue components, reusable composables, Pinia stores, routes, forms, and performance improvements.
Why use it?
It gives Vue projects consistent patterns and helps avoid common problems such as oversized components, tangled state, and unnecessary work in the browser.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 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 yesterday.

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.

Origin

This is a copy

100% identical to vue — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Vue.js Best Practices

Component Structure

  • Use Composition API over Options API
  • Keep components small and focused
  • Use proper TypeScript integration
  • Implement proper props validation
  • Use proper emit declarations
  • Keep template logic minimal

Composition API

  • Use proper ref and reactive
  • Implement proper lifecycle hooks
  • Use composables for reusable logic
  • Keep setup function clean
  • Use proper computed properties
  • Implement proper watchers

State Management

  • Use Pinia for state management
  • Keep stores modular
  • Use proper state composition
  • Implement proper actions
  • Use proper getters
  • Handle async state properly

Performance

  • Use proper component lazy loading
  • Implement proper caching
  • Use proper computed properties
  • Avoid unnecessary watchers
  • Use proper v-show vs v-if
  • Implement proper key management

Routing

  • Use Vue Router properly
  • Implement proper navigation guards
  • Use proper route meta fields
  • Handle route params properly
  • Implement proper lazy loading
  • Use proper navigation methods

Forms

  • Use v-model properly
  • Implement proper validation
  • Handle form submission properly
  • Show proper loading states
  • Use proper error handling
  • Implement proper form reset

TypeScript Integration

  • Use proper component type definitions
  • Implement proper prop types
  • Use proper emit declarations
  • Handle proper type inference
  • Use proper composable types
  • Implement proper store types

Testing

  • Write proper unit tests
  • Implement proper component tests
  • Use Vue Test Utils properly
  • Test composables properly
  • Implement proper mocking
  • Test async operations

Best Practices

  • Follow Vue style guide
  • Use proper naming conventions
  • Keep components organized
  • Implement proper error handling
  • Use proper event handling
  • Document complex logic

Build and Tooling

  • Use Vite for development
  • Configure proper build setup
  • Use proper environment variables
  • Implement proper code splitting
  • Use proper asset handling
  • Configure proper optimization

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.

vue is a cursor rule published in the GitHub repository mitas/cursor-rules (2 stars, last pushed 1y ago), licensed MIT. It adds 440 tokens to every session, about $0.0022 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to vue, differing in 0 lines, and is treated as a copy.
