the titel says it all – is there a maximum size for an event (or message) i want to send from the server to the client?<\/p>\n

i want to send a json string to the client and it looks something like this:<\/p>\n

[{\"id\":\"4e25434f0f110ec101000005\",\"media\":\"4fb135d508e972664c5adf3.jpg\"},\n {\"id\":\"4e2545f30f110ec101000021\",\"media\":\"d09b745414e251695aa33e04.jpg\"},\n {\"id\":\"4e2554ce7bcfb24702000012\",\"media\":\"076eea872411e433b9.png\"},\n {\"id\":\"4e255bc4f34a41cb02000010\",\"media\":\"c2af3db4707db3ece.png\"}]\n<\/code><\/pre>\n
if the array would contain e.g. 200 items, would this crash?!<\/p>\n

  1. \n
    It would not crash, I accidentally send a array of 250 extreme large objects over Socket.IO and it handled it without any issues.<\/p>\n
    You can just see it as sending a JSON object of 250 items over a http request, it could just take a while for the user to download it all.. Thats basically the only limitation you would be having.<\/p>\n<\/li>\n
  2. \n
    I dont think that will crash as node.js has an inbuilt nagle algorithm (if u havent disabled it) which buffers the data before sending it .<\/p>\n
    http:\/\/www.nodejs.org\/docs\/v0.5.1\/api\/net.html#socket.setNoDelay<\/p>\n
    Node.js alone can handle it easily for benchmarking purposes i have sent 800kb data in a chunk (random flush) . it took a lot of time to recieve on other side but was sent successfully.<\/p>\n<\/li>\n<\/ol>\n
