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.

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} />

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.
`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
`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.
`validationMessage`	`string`	"Validation Error"	Custom message for validation failures to `onEdit`, `onAdd`, or `onDelete` callbacks

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.

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

Linux and Docker (Recommended)

Use Docker to run the source code in a local development environment:

Clone this repo
Build the docker image
- cd react-json-view
- ./docker/build-container.sh
- note: you may need to use sudo to run docker commands
Run the docker container on port 2000. This will run the webpack-dev-server with hot-reloading enabled.
- ./docker/dev-server.sh
- note: you may need to use sudo to run the server file
Open port 2000 in your browser
- navigate to localhost:2000

Your source code will be mounted inside the docker container. The container is built on the latest Node:slim image.

Webpack-dev-server is running in the container and hot-reloading when changes are made locally.

All node modules are installed within the container, so make sure to rebuild your container if you make changes to package.json (see step 2, above).

Standard Workflow

Development workflow is setup for linux users with Docker installed. You can contribute with other configurations but I have not tested them.

Clone this repo
Install npm dependencies

cd react-json-view
npm install

Run webpack to start webpack-dev-server with hot-reloading enabled
- npm run dev:hot
Open port 2000 in your browser
- navigate to localhost:2000

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.

To-Do's

Improve documentation for onEdit, onAdd and onDelete props
Improve style organization
Continue size analysis and remove larger dependencies from build where possible
As always, improve test quality and coverage
update screenshots and docs in README
