SSE (server sent events) server response handling

I have set up some server sent events basically to listen for new messages. I create a connection with an EventSource in the browser which makes a request to the server. My server response is the following:

res.writeHead(200,
'Content-Type': 'text/event-stream',
'Cache-Control': 'no-cache',
'Connection': 'keep-alive'
)


The Problem is that my server will give a timeout error when there's no "full response" received within 50s...

The only workaround I found until now is to send a "ping" event every 50 seconds to tell that the connection is still alive like this:

sendPing()
function sendPing()
setTimeout(function()
res.sseSend(null,'heartbeat') //this simulates an actual event
sendPing()
, 50000)



Is that a good idea? A bad idea? Is there a better solution? Will this cause any problems in a single threaded application?

Thank you so much!
