JsObjectProxyHelper

Convert object to proxy to protect the object's properties and the object itself.
Allows to declare _private, _protected and _mutable all arrays with prop names.

# Note: **For better maintenance, this library has been placed along with JsUtilities (https://github.com/knighttower/JsUtility) to create an easier entry point for many resources that will collaborate together** --> only the docs will remain here for now.

Installation

npm i @knighttower/js-utility-functions

yarn add @knighttower/js-utility-functions

import ProxyHelper from '@knighttower/js-utility-functions';

Usage

Basic Usage

Here is how you can use the ProxyHelper function:

const proxy = ProxyHelper({
    objectProps: 'your object properties here',
    _protected: ['prop1', 'prop2'],
    _private: ['prop3'],
    _mutable: ['prop4'],
});
/**
 * @example ProxyHelper({objectProps..., _protected: array(...)})
 * @param {Object} object
 * @return {Proxy}
 * @usage const proxy = ProxyHelper({objectProps..., _protected: array(...), _private: array(...), _mutable: array(...)})
 * @usage _protected: array(...) -> Cannot be modified
 * @usage _private: array(...) -> Cannot be accessed
 * @usage _mutable: array(...) -> Can be modified
 */

Property Modifiers

• _protected: Properties that cannot be modified.
• _private: Properties that cannot be accessed.
• _mutable: Properties that can be modified.

Examples

Creating a Proxy with Protected and Private Properties

const myObject = {
    prop1: 'This is a public property',
    prop2: 'This is a protected property',
    prop3: 'This is a private property',
};

const proxy = ProxyHelper({
    ...myObject,
    _protected: ['prop2'],
    _private: ['prop3'],
});

console.log(proxy.prop1); // Output: "This is a public property"
console.log(proxy.prop2); // Output: Error
console.log(proxy.prop3); // Output: Error

Just proxy the object

const myObject = {
    prop1: 'This is a public property',
    prop2: 'This is a protected property',
    prop3: 'This is a private property',
};

const proxy = ProxyHelper(myObject);
