I'm trying to implement basic rails4 code with eventsource API & Action controller live, Everything is fine but I'm not able to reach event listner .
Controller code:
class HomeController < ApplicationController
include ActionController::Live
def tester
response.headers["Content-Type"] = "text/event-stream"
3.times do |n|
response.stream.write "message: hellow world! \n\n"
sleep 2
end
end
Js code:
var evSource = new EventSource("/home/tester");
evSource.onopen = function (e) {
console.log("OPEN state \n"+e.data);
};
evSource.addEventListener('message',function(e){
console.log("EventListener .. code..");
},false);
evSource.onerror = function (e) {
console.log("Error State \n\n"+e.data);
};
& When i reloading the page, My console output was "OPEN state" & then "Error State" as output.. event-listener code was not displaying .
1.When I'm curling the page, "message: Hellow world!" was displaying.
2.I changed in development.rb
config.cache_classes = true
config.eager_load = true
3. My browsers are chrome & firefox are latest versions, so no issues with them,
Where I'm missing? suggestions please!
