Extracting a sorted result from a given JSON object or array even string, parse and stringify with JSON3.
'use srtrict';
const jsonSorter = require('json-sorter');
jsonSorter(json [,options]);The first parameter json could be an object or array, even a json string.
By default, options.parse is true, you can set it to false so that it will not try to parse string to object or array.
Of course you can pass an user-defined parse function which will trigger a json-string parameter.
options.stringify is used to judge whether to stringify the sorted result, and usually you don't need to set it.
If you don't set options.compare, the json with be sorted according to the dictionary. It with be used to sort the keys of the parsed object like Array.prototype.sort.
See Array.prototype.sort for more information.
A complex example is as follows:
const jsonSorter = require('json-sorter');
const _ = require('underscore');
jsonSorter([{key: 1}, {key: 3}, {key: 2}, {key: {c: 1, d: 2, a: 3, b: 4}}], {
compare: function (x, y) {
if (_.isObject(x)) {
return x.key < y.key;
}
return x < y;
}
}));
// outputs : '[{"key":3},{"key":2},{"key":1},{"key":{"d":2,"c":1,"b":4,"a":3}}]'Yeah, as yo see it's very simple.
