1. Make sure you have npm
and the Polymer CLI installed.

1. When in the ace-widget directory, run npm install to install dependencies.

1. Serve the project using Polyumer CLI:

polymer serve --module-resolution node --component-dir node_modules

Like console.log. Consider this as a glorified version of

JSON.stringify(data, null, 2)

###### 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 {Object}: the Javascript object you would like to inspect

#### name {String}: specify the optional name of the root node, default to undefined

#### expandLevel {Number}: an integer specifying to which level the tree should be initially expanded.

#### expandPaths {String|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 {Boolean}: show non-enumerable properties.

#### sortObjectKeys {Boolean|Function}: Sort object keys with optional compare function.

#### nodeRenderer {Function}: 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:

`javascript
import './granite-inspector-object-label';
import './granite-inspector-object-root-label';

const defaultNodeRenderer = ({ depth, name, data, isNonEnumerable }) => {
return html
${depth === 0 ?
html name=${name} data=${data}> :
html
name=${name} data=${data} isNonEnumerable=${isNonEnumerable}>
}
;
};
`




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:
