How can i use server sent event with angular 6. I need to be getting data from backend periodically. I used it the normal way but it's not working
this.source=EventSource(url);
this.source.onmessage=(event) =>alert(event.data);

You should instantiate the this.source object with a new EventSource like this:
this.source = new EventSource(url);
You can also add an event listener for messages that come in from your backend like this:
this.source.addEventListener('message', message => { alert(message.data); });
Use the network tab within your browser's developer tools to ensure that the connection to the SSE is established and that messages are being received by the client.
