Install the package:

npm install inspx --save-dev

Wrap the root of your application or arbitrary component trees:

import Inspect from 'inspx'; <Inspect> <App /> </Inspect>


Inspect elements by hovering an element and holding Option (⌥) simultaneously.


By default, any element with padding, margin, or width and height is inspectable.

You can disable certain properties:

<Inspect margin size={false} padding={false} > <App /> </Inspect>


By default, the component will only be enabled in the development environment.

You can configure this behavior with the disabled prop:

<Inspect disabled={ process.env.NODE_ENV === 'staging' || process.env.NODE_ENV === 'production' } > <App /> </Inspect>

Optionally, you can leverage code splitting by wrapping the exported component and using your own instead.

The library is lightweight enough for this to likely be a premature and insignificant optimization.

import * as React from 'react'; import { InspectProps } from 'inspx'; const Inspect = React.lazy(() => import('inspx')); export default function Loader(props: InspectProps) { if (process.env.NODE_ENV === 'production') { return props.children; } return ( <React.Suspense fallback={null}> <Inspect disabled={false} {...props} /> </React.Suspense> ); }
