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.

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.
