• Broadcast events to channels (event names).
• Built-in support for connection and listener limits.
• Optional token-based authentication per connection.
• Heartbeat support to keep connections alive.
• Reactive state management with automatic broadcasting.

Installation

To install, use the following command:

npm install evstream

Usage
