WeakStoreJS 🚀

A lightweight library to store private data for objects in JavaScript using WeakMap, supporting multiple keys per object.

🔹 Why WeakStoreJS?

JavaScript doesn’t have built-in private properties for plain objects. WeakMap can help, but its API can be verbose. WeakStoreJS simplifies this:

• Store multiple private keys per object easily.
• Automatically garbage-collected when objects are removed.
• Clean, intuitive API.
• Makes your code safer and easier to maintain.

⚡ Installation

npm install weakstorejs

yarn add weakstorejs

🔹 Usage

import createPrivateStore from 'weakstorejs';

// Create a private store
const privateStore = createPrivateStore();

// Example object
const user = { name: 'Harsh' };

// Store private data
privateStore.set(user, 'creditCard', '1234-5678-9012-3456');

// Retrieve private data
console.log(privateStore.get(user, 'creditCard')); // Output: 1234-5678-9012-3456

// Check if key exists
console.log(privateStore.has(user, 'creditCard')); // Output: true

// Delete a key
privateStore.delete(user, 'creditCard');
console.log(privateStore.has(user, 'creditCard')); // Output: false
