react-json-view

RJV is a React component for displaying and editing javascript arrays and JSON objects.

This component provides a responsive interface for displaying arrays or JSON in a web browser. NPM offers a distribution of the source that's transpiled to ES5; so you can include this component with any web-based javascript application.

Props

Name	Type	Default	Description
`src`	`JSON Object`	None	This property contains your input JSON
`name`	`string`	`JSX.Element` or `false`	"root"
`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 (eg. `"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

Use Your Own 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.

onEdit, onAdd and onDelete Interaction

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.
