name |
string or JSX.Element |
false |
"root" - Contains the name of your root node. Use null or false for no name. |

RJV supports base-16 themes. Check out the list of supported themes in the demo. A custom "rjv-default" theme applies by default. |
style |
object |
{} |
Style attributes for react-json-view container. Explicit style attributes will override attributes provided by a theme. |

collapsed |
boolean or integer |
false |
When set to true, all nodes will be collapsed by default. Use an integer value to collapse at a particular depth. |
collapseStringsAfterLength |
integer |
false |
When an integer value is assigned, strings will be cut off at that length. Collapsed strings are followed by an ellipsis. String content can be expanded and collapsed by clicking on the string value. |
shouldCollapse |
(field)=>{} |
false |
Callback function to provide control over what objects and arrays should be collapsed by default. An object is passed to the callback containing name, src, type ("array" or "object") and namespace. |
groupArraysAfterLength |
integer |
100 | When an integer value is assigned, arrays will be displayed in groups by count of the value. Groups are displayed with bracket notation and can be expanded and collapsed by clicking on the brackets. |

displayDataTypes |
boolean |
true |
When set to true, data type labels prefix values. |
onEdit |

You can pass callback methods to onEdit, onAdd and onDelete props.
Your method will be invoked when a user attempts to update your src object.
The following object will be passed to your method:
{
updated_src: src, //new src value
name: name, //new var name
namespace: namespace, //list, namespace indicating var location
new_value: new_value, //new variable value
existing_value: existing_value, //existing variable value
}Returning false from a callback method will prevent the src from being affected.
You can specify a theme name or object when you instantiate your rjv component.
<ReactJsonView src={my_important_json} theme="monokai" />The following themes are builtin with the library:
'apathy''ashes''atelierDune''atelierForest''atelierHeath''atelierLakeside''atelierSeaside''bespin''brewer''bright''chalk''codeschool''colors''eighties''embers''flat''google''grayscale''greenscreen''harmonic''hopscotch''isotope''marrakesh''mocha''monokai''ocean''paraiso''pop''railscasts''shapeshifter''solarized''summerfruit''threezerotwofour''tomorrow''tube''twilight'
Check react-json-view.microlink.io to see how they look like.
rjv supports any base-16 theme. You can supply your own base-16 theme object.
To better understand custom themes, take a look at my example implementation and the base-16 theme styling guidelines.
