# React component names are minified

`smooth/react-no-names` · severity **info** · category Smoothness · detected by `void smooth` and `void audit`

## Why it matters

The production build minifies component names, so the React findings above name components like `hW`. The DOM selector and snippet in each finding still locate the component, but per-component attribution is harder and there are no render timings.

## How to fix it

Use the selector and HTML snippet in each React finding to find the component. For readable names and timings, audit a build that keeps function names and uses the React profiling build (`next build --profile`), or set displayName on hot components.
