Info

We forked this repo because we needed checkboxes to select nodes in json. You are free to use this package but if you need reliablity use origin package. We will not maintain this code, probably.

Usage

Install package with:

npm i @pirireis/react-json-view

and use like original package.

New Props

Name	Type	Default	Description
~~selectable~~	Boolean	false	This was redundant and removed. onSelect will decide if checkboxes are necessary.
onSelect	(data, checked)=>{}	false	Previous behaviour has been removed, checkboxes trigger this function when clicked. No triggers present on value click.
selectWithValues	Boolean	false	data in select callback will include values of that node if this prop is true.
customButtons	Array<{title, onClick: (event, data) => {}, visibleFor, render}>	undefined	Renders custom buttons with render function. Title is for html title attr. visibleFor should be an array contains all types where button should be visible. onClick is obvious.

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.

Check out the Interactive Demo

Implementation Example

// import the react-json-view component
import ReactJson from 'react-json-view'

// use the component in your app!
<ReactJson src={my_json_object} />

Output Examples

Default Theme

Hopscotch Theme, with Triangle Icons:

Installation Instructions

Install this component with NPM.

npm install --save react-json-view

Or add to your package.json config file:

"dependencies": {
    "react-json-view": "latest"
}

Props

Name	Type	Default	Description
src	JSON Object	None	This property contains your input JSON
name	string or 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 brakcet notation and can be expanded and collapsed by clickong 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
validationMessage	string	"Validation Error"	Custom message for validation failures to onEdit, onAdd, or onDelete callbacks

Features

• onEdit, onAdd and onDelete props allow users to edit the src variable
• Object, array, string and function values can be collapsed and expanded

Customizing Style

Stock Themes

RJV now supports base-16 themes!

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

<ReactJson src={my_important_json} theme="monokai" />

Check out the list of supported themes in the component demo.

Monokai theme example

Solarized theme example

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.

Contributing to the source code

Run the Dev Server

# clone this repository
git clone [email protected]:mac-s-g/react-json-view.git && cd react-json-view
# install dependencies
npm install --save-dev
# run the dev server with hot reloading
npm run dev

Webpack Dev Server should automatically open up http://localhost:2000 in your web browser. If it does not, open a browser and navigate to port 2000. The hot reloader will automatically reload when files are modified in the /src/ directory.

Run the Production Build

# run the build (note: you may need to use `sudo` priveledges to run the build successfully)
npm run build

Please add tests for your code before posting a pull request.

You can run the test suite with npm run test or npm run test:watch to automatically reload when files are modified.

Docker Tools

I recommend using docker for development because it enforces environmental consistency.

For information about contributing with Docker, see the README in ./docker.

Inspiration

I drew a ton of design ideas from react-json-tree. Thanks to the RJT contributors for putting together an awesome component!

I'm also inspired by users who come up with interesting feature requests. Reach out to me with ideas for this project or other projects you want to collaborate on. My email address is listed on my github user page.
