## Install

NPM:
```sh
npm install react-inspector
```

### &lt;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](http://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.

#### `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:
  ```
  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` for possible theming 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

## 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.
