Additional Methods
jp.transform(obj, template)
Template based json-to-json transformation.
const jp = require('ut-jsonpath');
const data = {
name: 'Bulgaria',
population: 7101859,
cities: [
{
name: 'Sofia',
'population': 1547472
},
{
name: 'Plovdiv',
'population': 544628
}
]
};
const template = {
countryName: '$.name',
population: '$.population',
cities: ['$.cities', {
cityName: '$.name'
}]
};
const transformed = jp.transform(data, template);
/*
{
countryName: 'Bulgaria',
population: 7101859,
cities: [
{
cityName: 'Sofia'
},
{
cityName: 'Plovdiv'
}
]
}
*/
Values are also composable. I.e. Multiple selectors can be specified. e.g: '$.name $.population' The necessary interpolations will be applied as long as the selectors are jsonpath compliant.
