Examples

All the below examples use the data.json file as the data input.

// Get the max latitude
cat data.json | unson 'map(get("latitude")), max()'
// Group names by eye color
cat data.json | unson 'groupBy(get("eyeColor")), map(map(get("name")))'

Acknowledgements

Inspired by other CLI JSON processors like jq and (most notably) fx.

Uses editor-widget from slap-editor for the repl text editing.

js-playgrounds was a big help in the initial setup of editor-widget.
