How can we pass headers

[dpvenkatesh]

Can you add an example of passing Authorization headers while connecting to see from the client.

This library manages the server-end of SSE, only.

If you want to be able to send headers from the client you should use an EventSource library that allows you to do so. EventSource/eventsource and Yaffle/EventSource are two good options.

For example, using EventSource/eventsource:

const eventsource = new EventSource(
  "/sse",
  {
    headers: {
      Authorization: "<content>"
    }
  }
);
