Every 45000 milliseconds retry request again and again

[MrJimmyYi]

I met a problem: "No activity within 45000 milliseconds. Reconnecting"
I use EventSourcePolyfill.But the background response time may take 5 minutes more than 45 seconds by default.
I tried many methods, but they are all failed. How to set its reconnection time according to custom Settings？

Hi! I found a solution in eventsource.js

> eventsource.js

function start(es, url, options){
...
var heartbeatTimeout = parseDuration(options.heartbeatTimeout, 45000);
...
}
Look! Our default 45000 and custom heartbeat times are here.

So, I tried to modify this line of code , Here is my modified code：
var heartbeatTimeout = parseDuration(options.headers.heartbeatTimeout, 45000);

Then I added heartbeatTimeout in the header to specify 3 minutes：
new EventSourcePolyfill(url,{ headers: { heartbeatTimeout: 180*1000 } })

Because I'm using Spring SseEmitter ，the server also sets a timeout period of 10 minutes:
SseEmitter sseEmitter = new SseEmitter(600000L);

This means I retry to connect to the server every 3 minutes during the 10-minute validity period

So, it worked，Won't retry to connect the server every 45 seconds, using a custom 5-minute time limit for requests instead. Perfect!

@udhayaas97 i switched to use this package instead: https://www.npmjs.com/package/eventsource

@cwirz , Thank you for your reply. There I have raised three issues.

1. Module not found error EventSource/eventsource#234
2. Angular Event source is not a constructor error EventSource/eventsource#235
3. ERROR TypeError: (intermediate value)(intermediate value)(intermediate value).request is not a function EventSource/eventsource#236

Is there any working example for Angular?

@MrJimmyYi I tried your solution, but no matter what changes I do in eventSource.js and pass heartbeatTimeout in headers, it is not reflecting. What could be wrong?
