API

Name	Type	Default	Description
src	JSON Object	None	This property contains your input JSON.
name	string or JSX.Element	false	"root" - Contains the name of your root node. Use null or false for no name.
theme	string	'rjv-default'	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.
iconStyle	string	'circle'	Style of expand/collapse icons. Accepted values are "circle", "triangle" or "square".
indentWidth	integer	4	Set the indent-width for nested objects.
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.
enableClipboard	boolean or (copy)=>{}	true	When prop is not false, the user can copy objects and arrays to clipboard by clicking on the clipboard icon. Copy callbacks are supported.
displayObjectSize	boolean	true	When set to true, objects and arrays are labeled with size.
displayDataTypes	boolean	true	When set to true, data type labels prefix values.
onEdit	(edit)=>{}	false	When a callback function is passed in, edit functionality is enabled. The callback is invoked before edits are completed. Returning false from onEdit will prevent the change from being made. see: onEdit docs
onAdd	(add)=>{}	false	When a callback function is passed in, add functionality is enabled. The callback is invoked before additions are completed. Returning false from onAdd will prevent the change from being made. see: onAdd docs
defaultValue	string | number | boolean | array | object	null	Sets the default value to be used when adding an item to JSON.
onDelete	(delete)=>{}	false	When a callback function is passed in, delete functionality is enabled. The callback is invoked before deletions are completed. Returning false from onDelete will prevent the change from being made. see: onDelete docs
onSelect	(select)=>{}	false	When a function is passed in, clicking a value triggers the onSelect method to be called.
sortKeys	boolean	false	Set to true to sort object keys.
quotesOnKeys	boolean	true	Set to false to remove quotes from keys (e.g., "name": vs. name:).
validationMessage	string	"Validation Error"	Custom message for validation failures to onEdit, onAdd, or onDelete callbacks.
displayArrayKey	boolean	true	When set to true, the index of the elements prefix values.
escapeStrings	boolean	true	When set to true, strings sequences such as \n, \t, \r, \f will be escaped.

Callbacks

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.
