object-auto-properties

Some functions that deal with object properties

How to use

Install through npm with

npm i DevinF06/object-auto-properties

Require the module in your code

const objectProperties = require('object-auto-properties');

// or

const { duplicateObject, autoDefineProperties, autoDefineProperty } = require('object-auto-properties');

Functions

duplicateObject(o)

Duplicates object o, including properties and nested objects

const { duplicateObject } = require('object-auto-properties');
var foo = {obj: {num: 1}}, bar = duplicateObject(foo);

bar.obj.num = 2;
console.log(foo.obj.num == bar.obj.num); // false

autoDefineProperties(o, p)

Defines "autoProperties" p in object o

For better reference see Object.defineProperties and autoDefineProperty

const { autoDefineProperties } = require('object-auto-properties');
var object = {}, foo = 1;
object = autoDefineProperties(foo, {
  foo: {value: () => `foo is ${foo}`},
  bar: {value: 'text'}
});

foo = 2;
console.log(object.foo); // foo is 2
console.log(object.bar); // text

autoDefineProperty(o, k, v)

Defines "autoProperty" k in object o with property v

"autoProperties" are like regular object properties, except that if their value is a function, they will evaluate it

When "autoProperties" are defined they will remain until removed (with delete object.foo or ect.)

const { autoDefineProperty } = require('object-auto-properties');
var object = {}, foo = 1;
object = autoDefineProperty(object, 'foo', {value: 'bar'});
console.log(object.foo); // bar

object.foo = () => `foo is ${foo}`;
foo = 2;
console.log(object.foo) // foo is 2
