react-inspector

Power of Browser DevTools inspectors right inside your React app. Check out the interactive playground.

Install

NPM:

install react-inspector

<Inspector />

A shorthand for the inspectors.

• <Inspector/> is equivalent to <ObjectInspector> or <DOMInspector> if inspecting a DOM Node.
• <Inspector table/> is equivalent to <TableInspector>.

<ObjectInspector />

Like console.log. Consider this as a glorified version of <pre>JSON.stringify(data, null, 2)</pre>.

How it works

Tree state is saved at root. If you click to expand some elements in the hierarchy, the state will be preserved after the element is unmounted.

API

The component accepts the following props:

data: PropTypes.any: the Javascript object you would like to inspect name: PropTypes.string: specify the optional name of the root node, default to undefined expandLevel: PropTypes.number: an integer specifying to which level the tree should be initially expanded. expandPaths: PropTypes.oneOfType([PropTypes.string, PropTypes.array]): an array containing all the paths that should be expanded when the component is initialized, or a string of just one path

• The path string is similar to JSONPath.
• It is a dot separated string like $.foo.bar. $.foo.bar expands the path $.foo.bar where $ refers to the root node. Note that it only expands that single node (but not all its parents and the root node). Instead, you should use expandPaths={['$', '$.foo', '$.foo.bar']} to expand all the way to the $.foo.bar node.
• You can refer to array index paths using ['$', '$.1']
• You can use wildcard to expand all paths on a specific level
  • For example, to expand all first level and second level nodes, use ['$', '$.*'] (equivalent to expandLevel={2})
• the results are merged with expandLevel

showNonenumerable: PropTypes.bool: show non-enumerable properties. sortObjectKeys: PropTypes.oneOfType([PropTypes.bool, PropTypes.func]): Sort object keys with optional compare function.

<TableInspector />

Like console.table.

API

The component accepts the following props:

data: PropTypes.oneOfType([PropTypes.array, PropTypes.object]): the Javascript object you would like to inspect, either an array or an object columns: PropTypes.array: An array of the names of the columns you'd like to display in the table

<DOMInspector />

API

The component accepts the following props:

data: PropTypes.object: the DOM Node you would like to inspect

Usage

rt {ObjectInspector, TableInspector} from 'react-inspector';

r use the shorthand
rt Inspector from 'react-inspector';

t MyComponent = ({ data }) =>
iv>
<ObjectInspector data={data} />
<TableInspector data={data} />

<Inspector data={data} />
<Inspector table data={data} />
div>

data = { /* ... */ };

tDOM.render(
yComponent data={data} />,
cument.getElementById('root')

Try embedding the inspectors inside a component's render() method to provide a live view for its props/state (Works even better with hot reloading).

More Examples

Check out the storybook for more examples.

install && npm run storybook

Open http://localhost:9001/

Theme

By specifying the theme prop you can customize the inspectors. theme prop can be

1. a string referring to a preset theme ("chromeLight" or "chromeDark", default to "chromeLight")
2. or a custom object that provides the necessary variables. Checkout src/styles/themes for possible theming variables.

Example 1: Using a preset theme:

pector theme="chromeDark" data={{a: 'a', b: 'b'}}/>

Example 2: changing the tree node indentation by inheriting the chrome light theme:

rt { chromeLight } from 'react-inspector'

pector theme={{...chromeLight, ...({ TREENODE_PADDING_LEFT: 20 })}} data={{a: 'a', b: 'b'}}/>

Roadmap

Type of inspectors:

• [x] Tree style
• [x] common objects
• [x] DOM nodes
• [x] Table style
• [ ] Column resizer
• [ ] Group style

Notes

• react-object-inspector package will be deprecated. <ObjectInspector/> is now part of the new package react-inspector.
• Why inline style? This document summarizes it well.
