How to add headers and responseType in angular eventSource

I am working on one API/SSE where I get data in streams from backend. To recieve that on front end I am using eventSource. Its code is as below -

let source = new EventSource("url", {headers, responseType: 'text'});
source.addEventListener('message', message => {
    let n: Notification;
    n = JSON.parse(message.data);
    console.log(message.data);
});

But what error I am facing is -

Argument of type '{ headers: HttpHeaders; responseType: string; }' is not assignable to parameter of type 'EventSourceInit'.
Object literal may only specify known properties, and 'headers' does not exist in type 'EventSourceInit'.

How can I add headers and responseType in eventSource?

Any help is appreciated.

Thanks a lot!

You can't add it. EventSource() itself does not accept such params (like the error message said too). What is the end-result you are looking for?

If you are trying to get the credentials, you could try this:

let source = new EventSource("url", { withCredentials: true } );

All possible params and methods of the API: https://developer.mozilla.org/en-US/docs/Web/API/EventSource
