> **Note:** This is a fork of [react-json-view](https://github.com/microlinkhq/react-json-view). We forked this project because we don't need keys to have hover card support. The fork is maintained at [https://github.com/with-ours/react-json-view](https://github.com/with-ours/react-json-view).

**react-json-view** (rjv) is a React component for displaying and editing javascript **arrays** and **JSON objects**.

![](https://raw.githubusercontent.com/microlinkhq/react-json-view/docs/docs/assets/banner.png)

### Highlights

* `onEdit`, `onAdd` and `onDelete` props allow users to edit the `src` variable.
* Object, array, string and function values can be collapsed and expanded.
* Object and array nodes display length.
* Object and array nodes support a "Copy to Clipboard" feature.
* String values can be truncated after a specified length.
* Arrays can be subgrouped after a specified length.
* Base-16 Theme Support.
* When `onEdit` is enabled:
   * `Ctrl/Cmd+Click` Edit Mode
   * `Ctrl/Cmd+Enter` Submit

### Installation

```shell
npm install @microlink/react-json-view --save
```

### Usage

```js
import ReactJsonView from '@microlink/react-json-view'

<ReactJsonView
  src={{
  string: 'this is a test string',
  integer: 42,
  array: [1, 2, 3, 'test', NaN],
  float: 3.14159,
  undefined: undefined,
  object: {
    'first-child': true,
    'second-child': false,
    'last-child': null
    },
  string_number: '1234',
  date: new Date(),
  bigNumber: new BigNumber('0.0060254656709730629123')
  }}
  showComma
/>

Use `null` or `false` for no name.                                                                                                                                                                                          |

Check out the list of supported themes [in the demo](https://react-json-view.microlink.io/). A custom "rjv-default" theme applies by default.                                                                                                |

Explicit style attributes will override attributes provided by a theme.                                                                                                                                                   |

Accepted values are "circle", "triangle" or "square".                                                                                                                                                                                     |

Use an integer value to collapse at a particular depth.                                                                                                                                                       |

Collapsed strings are followed by an ellipsis. String content can be expanded and collapsed by clicking on the string value.                                                                   |

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.                                                                    |

The callback receives an object with `src`, `namespace`, and `name` properties. If not provided or set to `false`, the clipboard icon will not be displayed.                                                                                                                              |

The callback is invoked before edits are completed. Returning `false` from `onEdit` will prevent the change from being made. [see: onEdit docs](#onedit-onadd-and-ondelete-interaction)           |
| `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](#onedit-onadd-and-ondelete-interaction)          |
| `defaultValue`               | `string \| number \| boolean \| array \| object` | `null`                   | Sets the default value to be used when adding an item to JSON.                                                                                                                                                                                                            |

The callback is invoked before deletions are completed. Returning `false` from `onDelete` will prevent the change from being made. [see: onDelete docs](#onedit-onadd-and-ondelete-interaction) |

The class should have a constructor that accepts a numeric string/value and a `name` property for display purposes. You can use existing libraries like `bignumber.js`, `decimal.js`, `big.js`, or provide your own implementation.                                                                                                               |

Interactive tools (clipboard, edit, delete icons) appear after the comma when hovering over JSON elements.                                                                                                                              |

#### 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:
```js
{
    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.

### Theming

#### Builtin theme

You can specify a `theme` name or object when you instantiate your rjv component.

```jsx
<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'`
