object-tojson

Turn a Javascript primitive into its "flat" representation. Aims to be equivalent to JSON.parse(JSON.stringify(obj)). Note that it will recursively visit all properties and attempt to call toJSON, before trying to parse the value. undefined is not a valid JSON value, so it will attempt to remove properties that resolve to this value, unless it is an array element, in which case it resolves to null

Usage

 
const serialise = require('object-tojson')
 
serialise({
  key: 'value',
  arr: [undefined, null, true],
  keyFn: {toJSON: function () { return 'valueFn' }}
}) // => {key: 'value', [null, null, true], keyFn: 'valueFn'}
