0.0.1 • Public • Published

This package is fork from react-json-editor-ajrm and include bugs fixes which were left in the original version.


As you may already know, the react-json-editor-ajrm's orignal project is not actively maintained and that it will eventually be deprecated. So I've decided to set an official date for deprecation. The tentative date for this is June 15, 2023.

What does deprecation mean?

  • It means the Github project will be archived as read only.
  • It means the npm packages will appear deprecated, but it WILL NOT be deleted.
  • It means the new project will be available officially on that date.

I would like to thank those who used it in their projects and those who have contributed in some way to the project. I simply no longer wish to maintain this project. It was made in the early days of my software engineer career, and it has not caught up to today's standards nor mine.

But don't fret. I intend to breathe new life into this project rewriting it from the ground up.

I would like to take the learnings of the past, and avoid some of the issues react-json-editor-ajrm currently has. I would also like to highlight the things done well, and I wish to carry on.

I've setup home for this new project here enio. I've also set up a discussion here if you have any questions or comments.

A stylish, editor-like, modular, react component for viewing, editing, and debugging javascript object syntax!

Installing Dependency

  • Using node package manager:
   $ npm i --save react-json-editor-ajrm

How to Use

    import JSONInput from 'react-json-editor-ajrm';
    import locale    from 'react-json-editor-ajrm/locale/en';

        id          = 'a_unique_id'
        placeholder = { sampleObject }
        colors      = { darktheme }
        locale      = { locale }
        height      = '550px'

Hint: There are two different root paths: react-json-editor-ajrm and react-json-editor-ajrm/es. The first contains polyfilled ES5 code, the second unpolyfilled ES6. The react-json-editor-ajrm/es version is not compatible with create-react-app. If you are unsure of which one you need/want, pick the first - it has the best compatibility with tools and browsers.


The ./examples folder contains two examples:

  1. webpack-project - A basic example without much overload
  2. create-react-app-project - A small example using the create-react-app template

Testing right away!

  1. Fork and/or clone this Github repository
  2. Go to an example project under react-json-editor-ajrm/example:
    $ cd path/to/repo/react-json-editor-ajrm/example/webpack-project
  1. Install example project dependencies:
    $ npm i
  1. Serve sample website to port 8080:
   $ npm start
  1. Open http://localhost:8080 in the web browser
