Zero-dependency profiler with micro-kernel architecture. Track renders, detect wasted updates, and ship faster React apps.
import { ReactScopeProvider, useScope } from '@oxog/reactscope'
function App() {
return (
<ReactScopeProvider>
<Dashboard />
</ReactScopeProvider>
)
}
function Dashboard() {
const scope = useScope('Dashboard')
return (
<div>
<p>Renders: {scope.renderCount}</p>
<p>Avg: {scope.averageRenderTime.toFixed(2)}ms</p>
<p>Wasted: {scope.wastedRenders}</p>
</div>
)
