Power of [Browser DevTools](https://developers.google.com/web/tools/chrome-devtools/) inspectors right inside your React app. Check out the [interactive playground](https://storybookjs.github.io/react-inspector/) or [storybook](https://react-inspector.netlify.com).

## Install

NPM:

```sh
npm install react-inspector
```

Recommended versions:

- version `3.0.2`: If you are using React 16.8.4 or later.
- version `2.3.1`: If you are using an earlier version of React.

## Getting started

### <Inspector />

A shorthand for the inspectors.

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

### &lt;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](https://goessner.net/articles/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

When `sortObjectKeys={true}` is provided, keys of objects are sorted in alphabetical order except for arrays.

**`nodeRenderer: PropTypes.func`:** Use a custom `nodeRenderer` to render the object properties (optional)

- Instead of using the default `nodeRenderer`, you can provide a
  custom function for rendering object properties. The _default_
  nodeRender looks like this:

  ```js
  import { ObjectRootLabel } from 'react-inspector'
  import { ObjectLabel } from 'react-inspector'

  const defaultNodeRenderer = ({ depth, name, data, isNonenumerable, expanded }) =>
    depth === 0
      ? <ObjectRootLabel name={name} data={data} />
      : <ObjectLabel name={name} data={data} isNonenumerable={isNonenumerable} />;
  ```

### &lt;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

### &lt;DOMInspector />

#### API

The component accepts the following props:

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

#### Usage

```js
import {ObjectInspector, TableInspector} from 'react-inspector';

// or use the shorthand
import Inspector from 'react-inspector';

const MyComponent = ({ data }) =>
  <div>
    <ObjectInspector data={data} />
    <TableInspector data={data} />

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

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

ReactDOM.render(
  <MyComponent data={data} />,
  document.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.

```sh
npm install && npm run storybook
```

## 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`](https://github.com/storybookjs/react-inspector/tree/master/src/styles/themes) for possible theme variables.

**Example 1:** Using a preset theme:

```js
<Inspector theme="chromeDark" data={{a: 'a', b: 'b'}}/>
```

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

```js
import { chromeLight } from 'react-inspector'

<Inspector 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

Contribution is welcome. [Past contributors](https://github.com/storybookjs/react-inspector/graphs/contributors)

## Additional

- If you intend to capture `console.log`s, you may want to look at [`console-feed`](https://www.npmjs.com/package/console-feed).
- `react-object-inspector` package will be deprecated. `<ObjectInspector/>` is now part of the new package `react-inspector`.
- Why inline style? [This document](https://github.com/erikras/react-redux-universal-hot-example/blob/master/docs/InlineStyles.md) summarizes it well.
