**Egyptian ID Validator** is a production-ready JavaScript module for validating and parsing Egyptian national ID numbers.  
It enforces the official structural rules defined by the Egyptian Ministry of Interior, including a verified but undisclosed checksum mechanism.

> ℹ️ This package is part of a broader multi-language validation system.  
> For other implementations (e.g., Python, Java), see the [Egyptian-ID-Validator](https://github.com/MohamedAAbdallah/Egyptian-ID-Validator) mother repository.

---

## 🔍 Features

- ✅ **Format Validation** – Ensures the ID is 14 digits and correctly structured.
- ✅ **Checksum Validation** – Verifies integrity using an official checksum method.
- ✅ **Component Extraction** – Parses the ID into:
  - Year, Month, and Day of Birth
  - Governorate Name and Code
  - Gender (Male/Female)

---

## 📦 Installation

Install via npm:

```bash
npm install egyptian-id-validator
````

> Requires Node.js ≥ 14

---

## 🚀 Quick Usage

```js
import { validate } from "egyptian-id-validator";

const id = "29805150102054"; // Replace with your ID
const result = validate(id);

if (result) {
  console.log("✅ Valid ID");
  console.log(result); // { valid: true, year, month, day, governorate, gender }
} else {
  console.log("❌ Invalid ID");
}
```

You can also use this in CommonJS projects:

```js
const { validate } = require("egyptian-id-validator");
```

## 📁 Project Status

This package is **stable** and actively maintained.
