react-json-view

Interactive react component for displaying 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 an interactive demo here.

onEdit Interaction

Click the pencil icon to initialize an edit

Input a new value. RJV will attempt to recognize integer and float inputs.

Submitting a new value calls your onEdit callback method

The onEdit function is passed an edit variable. The edit variable will have the following contents:

const edit = {
    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
}

Contributing to the source code:

Standard Workflow

1. Clone this repo
2. Install npm dependencies

cd react-json-view
npm install

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

Development within a Docker Container

You can use Docker to run the source code in a local development environment:

1. Clone this repo
2. Make sure docker is installed
3. Build the docker image
   • docker build -t react-json-view .
   • note: you may need to use sudo to run docker commands
4. Run the docker container on port 2000. This will run the webpack-dev-server with hot-reloading enabled.
   • cd react-json-view
   • ./docker/dev-server.sh
   • note: you may need to use sudo to run the server file
5. 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 standard Node 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 3, above).

To-Do's

1. Support "delete" capability when onEdit is enabled
2. Support "add" capability when onEdit is enabled
