This module provides a Mercure Hub integration layer for Magento 2, enabling real-time server-sent events (SSE) across your storefront and admin panel. It handles JWT-based authentication for both publishing and subscribing, with separate secrets for each operation. Topics are managed through an extensible resolver system that supports both public (guest-accessible) and private (customer-specific) topic authorization.

Warning

This package is currently in **alpha** (`0.1.0-alpha1`). The API is unstable and may introduce breaking changes between releases. Do not use in production.

⭐ Features
----------

[](#-features)

- **SharedWorker SSE** — Single connection shared across browser tabs with automatic reconnection
- **JWT Authentication** — Separate publisher/subscriber token generation with configurable secrets, algorithms (HMAC SHA-256/384/512), and TTL
- **Topic-based authorization** — Third-party modules have an ability to register their own topics. Public and private topic separation with user-scoped access control
