Question

How do you receive server-sent event notifications in Javascript?

Answer 1

The EventSource object is used to receive server-sent event notifications. For example, you can receive messages from server as below,

if (typeof EventSource !== "undefined") {
  var source = new EventSource("sse_generator.js");
  source.onmessage = function (event) {
    document.getElementById("output").innerHTML += event.data + "<br>";
  };
}
