Vue.js code review, security audit, and performance optimization
Vue is a popular frontend framework that some AI tools generate as an alternative to React. GPT Engineer, Bolt, and certain Cursor configurations produce Vue applications. Vibe coded Vue apps often have reactivity pitfalls, missing route guards, and security gaps that are unique to Vue's approach.
Common Vue issues we find
Real problems from Vue codebases we've reviewed.
Using v-html with unsanitized content
The v-html directive renders raw HTML, and AI tools use it to display dynamic content without sanitization - creating cross-site scripting (XSS) vulnerabilities.
Missing route guards for protected pages
Vue Router navigation guards not implemented, so authenticated-only pages are accessible to anyone who types in the URL directly.
Reactivity pitfalls with objects and arrays
AI-generated Vue code adds properties to objects or modifies arrays in ways Vue's reactivity system can't detect, causing the UI to not update when data changes.
Watchers without cleanup
Watch effects that set up intervals, subscriptions, or event listeners without returning a cleanup function, causing memory leaks and duplicate handlers.
Oversized component bundles
All routes and components bundled into a single file instead of using dynamic imports and lazy loading, causing slow initial page loads.
State management without persistence
Pinia or Vuex stores that lose all state on page refresh because no persistence strategy was implemented, frustrating users who lose their work.
Missing error boundaries
No errorCaptured hooks or error boundaries in the component tree. A single component error crashes the entire application with no fallback UI.
API keys in frontend config
Secret API keys placed in .env files with VITE_ prefix, making them visible in the browser's JavaScript bundle to anyone who inspects it.
Vue production checklist
Key checks before deploying your Vue app.
No v-html with unsanitized or user-provided content
Vue Router guards protect authenticated routes
Reactivity-safe patterns for objects and arrays
Watch effects include cleanup functions
Route-level code splitting with dynamic imports
Error boundaries with errorCaptured in key components
No secret keys in VITE_ environment variables
Proper loading and error states for async data
Production build with minification and source maps disabled
Accessible keyboard navigation and ARIA attributes

Frequently asked questions
Can you review Vue code from an AI tool?
Yes. We review Vue applications built with any AI tool for security vulnerabilities, reactivity bugs, performance issues, and code quality. Vue has its own specific pitfalls that differ from React.
Should I use Vue or React?
Both are excellent choices. Vue has a gentler learning curve and great documentation. React has a larger ecosystem and more AI tool support. We work with both and can help you optimize either.
How do I improve my Vue app's performance?
We add lazy loading for routes, optimize component re-rendering, implement proper computed properties, fix watcher leaks, and configure tree-shaking - often cutting load times in half.
