Interactive react component for displaying javascript arrays and JSON objects.

Package Exports

    This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@vahagn13/react-json-view) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

    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 '@microlink/react-json-view'

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

}

    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

    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

    Run the Dev Server

    # clone this repository
git clone git@github.com: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!
