How to use this developer tool
- Paste a complete Vue component.
- Choose inspection depth.
- Run architecture and risk checks.
- Prioritize cleanup and deep-watcher recommendations.
#208 · Vue Developer Tool
Vue Inspector
Inspect Vue component complexity, state concentration, watcher usage, direct DOM access, cleanup risks, and refactoring opportunities.

What this developer tool does
Calculates transparent static metrics and maps them to maintainability and performance recommendations.
Count state/watchers/dependencies → detect cleanup patterns → calculate risk → recommend refactors
Scores are heuristics for prioritization, not substitutes for runtime profiling.
Example
Use the preloaded sample, run the tool, then inspect the output and status before copying it into a project.
Tips for better output
- Use complete framework code when possible.
- Select the matching framework version.
- Review heuristic findings before changing production code.
- Run the project compiler and tests after using generated or transformed output.
FAQ
How do I analyze Vue component complexity?
Paste the component and run the inspector to calculate transparent state, watcher, dependency, and cleanup metrics.
Can it detect missing timer cleanup in Vue?
It flags timer usage when no common unmount cleanup hook is found.
How do I find logic that should move to a composable?
High state concentration and watcher counts trigger composable-oriented recommendations.
Does the inspector measure runtime performance?
No. It estimates static risk and should be combined with runtime profiling.
What does the performance risk score mean?
It is a heuristic prioritization score derived from detected patterns.
