``js
import JSONTree from 'react-json-tree'
// If you're using Immutable.js: npm i --save immutable
import { Map } from 'immutable'

// Inside a React component:
const json = {
array: [1, 2, 3],
bool: true,
object: {
foo: 'bar'
}
immutable: Map({ key: 'value' })
}

You can pass a theme prop containing base16 theme data to change the theme. The example theme data can be found here.

(The theme data is also used by redux-devtools, and extracting it to a separate npm package is a TODO).

`js
const theme = {
scheme: 'monokai',
author: 'wimer hazenberg (http://www.monokai.nl)',
base00: '#272822',
base01: '#383830',
base02: '#49483e',
base03: '#75715e',
base04: '#a59f85',
base05: '#f8f8f2',
base06: '#f5f4f1',
base07: '#f9f8f5',
base08: '#f92672',
base09: '#fd971f',
base0A: '#f4bf75',
base0B: '#a6e22e',
base0C: '#a1efe4',
base0D: '#66d9ef',
base0E: '#ae81ff',
base0F: '#cc6633'
};

#### Customize CSS

You can pass the following properties to customize styling (all optional):

`js
({})}
getItemStringStyle={(type, expanded) => ({})}
getListStyle={(type, expanded) => ({})}
getLabelStyle={(type, expanded) => ({})}
getValueStyle={(type, expanded) => ({})} />
`

Here type is a string representing type of data, expanded is a current state for expandable items. Each function returns a style object, which extends corresponding default style.

For example, if you pass the following function:

`js
const getStyle = (type, expanded) =>
(expanded ? { textTransform: 'uppercase' } :
{ textTransform: 'lowercase' });
`

Then expanded nodes will all be in uppercase:

#### Customize Labels for Arrays, Objects, and Iterables

You can pass getItemString to customize the way arrays, objects, and iterable nodes are displayed (optional).

By default, it'll be:

`js
=> {itemType} {itemString}}
`

But if you pass the following:

`js
const getItemString = (type, data, itemType, itemString)
=> ( // {type});
`

Then the preview of child elements now look like this:

#### Customize Rendering

You can pass the following properties to customize rendered labels and values:

`js
labelRenderer={raw => {raw}}
valueRenderer={raw => {raw}}
/>
`

In this example the label and value will be rendered with and wrappers respectively.

#### More Options

- Add expandAll property to expand all nodes.
- Add hideRoot={true}` to hide a root node.
