proxy-assign v0.3.0

proxy-assign

Creates proxies of all existing properties of source object(s) onto a target object, without actually assigning anything onto the target.

In contrast to Object.assign:

The Object.assign() method copies properties from a source object to a target object. It uses [[Get]] on the source and [[Set]] on the target.

This doesn't copy and uses both [[Get]] and [[Set]] on the source (for properties that exist on it).

Modifying exiting properties (even primitives) alters them on the source object. Any new properties are still set on the target.

Install

npm i proxy-assign

Usage

API

const target = ProxyAssign(target, ...sources)

Example

const ProxyAssign = require('proxy-assign')

const source = { a: 'a' }
const target = {}
const proxy = ProxyAssign(target, source)

proxy.a = 0
proxy.b = 'b'

source: { a: 0 }
target: { b: 'b' }
proxy: Proxy { b: 'b' } // Proxy of target
