Can't set headers after they are sent. about timeout

[dougwilson]

I could wrap res.send in an if !res.headersSent but it seems a little excessive to do that for every route. I'm not sure how to best handle this situation.

There are two solutions:

1. You can do as you suggest: check if the request timed out once your timer fired.
2. When you set your timeout, also add a listener on the timeout event and then clear the timeout so your timer never even fires:

    .get("/", function (req, res, next) {
        var timer = setTimeout(function () {
            res.send({peaches:"yummy", turnips:"yucky"}); 
        }, 1000);
        req.once('timeout', function () {
          clearTimeout(timer);
        });
    })
