Get and Set object properties in a Fast and Elegant way. (with caching and no dependencies!)
Inspire by angular $parse service
Note: This kit works great with deep-keys (creates an array composed of the own enumerable property names of an object).
$ npm install --save obj-parsevar parse = require('obj-parse');
//object
var person1 = {
name: 'Ariel Mashraki',
address: { country: { name: 'Israel', city: 'Tel Aviv' } }
};
var person2 = {
name: 'Dan Louis',
address: { country: { name: 'Canada', city: 'Toronto' } }
};
//property getter
var nameGetter = parse('name');
nameGetter(person1); //Ariel Mashraki
nameGetter(person2); //Dan Louis
//nested propeties with dot notation
var cityGetter = parse('address.country.city');
cityGetter(person1); //Tel Aviv
cityGetter(person2); //Toronto
//bind a function
function ifCanadian(person) {
return person.address.country.name === 'Canada';
}
var getter = parse(ifCanadian);
getter(person1); //false
getter(person2); //true
//property setter, use the assign function
//return function(scope, value)
var countrySetter = parse('address.country.name').assign;
countrySetter(person1, 'Canada'); //return person1 with changes
countrySetter(person2, 'Israel'); //return person2 with changes
//use again in the ifCanadian
getter(person1); //true
getter(person2); //falseMIT © Ariel Mashraki
