Power of Browser DevTools inspectors right as a custom element.
> ## 🛠Status: In Development
> granite-inspector is currently in development. We encourage you to use it and give us your feedback, but there are things that haven't been finalized yet and you can expect some changes.


`html`
Install the component using npm:
`sh`
$ npm i @granite-elements/ace-widget --save
Once installed, import it in your application:
import '@granite-elements/ace-widget/ace-widget.js';
1. Fork the ace-widget repository and clone it locally.
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
1. Open the demo in the browser
- http://127.0.0.1:8080/components/@greanite-elements/ace-widget/demo
- is currently equivalent to
- DOM and table mode are under active development
. 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 $.foo.bar node.
- You can refer to array index paths using ['$', '$.1']
- You can use wildcard to expand all paths on a specific level
- For example, to expand all first level and second level nodes, use ['$', '$.*'] (equivalent to expandLevel={2})
- the results are merged with expandLevel####
showNonenumerable {Boolean}: show non-enumerable properties.####
sortObjectKeys {Boolean|Function}: Sort object keys with optional compare function.####
nodeRenderer {Function}: Use a custom nodeRenderer to render the object properties (optional)
- Instead of using the default nodeRenderer, you can provide a
custom function for rendering object properties. The _default_
nodeRender looks like this:
`javascript
import './granite-inspector-object-label';
import './granite-inspector-object-root-label'; const defaultNodeRenderer = ({ depth, name, data, isNonEnumerable }) => {
return html
name=${name} data=${data}> :
name=${name} data=${data} isNonEnumerable=${isNonEnumerable}>;
};
`
Theme
By specifying the theme prop you can customize the inspectors. theme prop can be1. 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:
