How can i detect connection is closed to refresh JWT tokens ?

[eguvenc]

Every request i send a JWT token at headers. When the connection is closed with 401 reason i want to recreate the EventSource object with new token.

Is there any way to detect connection is open or not ?

Listen for error event, you can even change the header by changing the property value

I tried to listen error event, it always come null even if connection closed

thanks, it works fine.

eventSource.onerror = function (event) {
  if (event.status == 401) {

  }        
};
