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.

Stock Themes

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 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.
