# MitIDIntegrator

A TypeScript class that simplifies authentication processes by managing popup window interactions and message handling.

## Key Concept

- Simplifies integration with authentication systems by handling popup window orchestration for user login and message reception.
- Automatically captures authentication codes upon receiving a success message.

## Features

- **Popup Window Management**: Easily open and close popup windows with specified URLs and configurations for a seamless user experience.
- **Message Listening**: Continuously monitors messages from popup windows, intelligently processing them based on their source and content.
- **Authentication Code Handling**: Safely captures authentication codes from successful logins and securely passes them to designated callback functions when instructed to close the popup.

## Getting Started

### Prerequisites

- **Environment variables**: Ensure the client possesses the requisite environment variables for the MitID broker.
- **Callback function**: Have a callback function in place to manage the authentication code.
- **Window Instance**: Have a window instance available for data consumption through the message event.

## Installation

```bash
npm install my-mitid-broker
```

### Usage

```typescript
// Initialize MitIDIntegrator
const env = {
  BROKER_DOMAIN: "https://mitid-broker.com",
  BROKER_CLIENTID: "client-id",
  REDIRECT_URI: "https://client.com/callback",
};
const integrator = new MitIDIntegrator();

// Open popup window for login
integrator.openPopup("https://example.com/login", (authCode) => {
  console.log("Received authentication code:", authCode);
});
```
