lukas-reining/eventsource

This is a custom EventSource implementation that extends the WHATWG Server-Sent Events specification by allowing additional configuration options like custom request headers, making it possible to send authorization headers and other metadata that the native browser EventSource doesn't support. It's designed for developers working with server-sent events who need more control over the connection setup, particularly when authentication or custom headers are required, and works in both web browsers and Node.js environments.
