Starting off with a basic node app, and I can't figure out how to beat this write after end error, even with the callbacks suggested on several sites.
index.js:
var server = require(./server);
var router = require(./router);
var requestHandlers = require(./requestHandlers);
var handle = {}
handle[/] = requestHandlers.start;
handle[/start] = requestHandlers.start;
handle[/upload] = requestHandlers.upload;
server.start(router.route, handle);
server.js:
var http = require(http);
var url = require(url);
function start(route, handle) {
function onRequest(request, response) {
var postData =;
var pathname = url.parse(request.url).pathname;
console.log(Request for + pathname + received.);
route(handle, pathname, response);
}
http.createServer(onRequest).listen(8888);
console.log(Server has started.);
}
exports.start = start;
router.js:
function route(handle, pathname, response) {
console.log(About to route a request for + pathname);
if (typeof handle[pathname] === 'function') {
handle[pathname](response);
}
else {
console.log(No request handler found for + pathname);
response.writeHead(404, {Content-Type: text/plain});
response.write(404 Not found);
response.end();
}
}
exports.route = route;
and now the culprit, requestHandlers.js:
function start(response) {
console.log(Request handler 'start' was called.);
var body = '<html>'+
'<head>'+
'<meta http-equiv=Content-Type content=text/html; '+
'charset=UTF-8 />'+
'</head>'+
'<body>'+
'<div>Hello Start</div>' +
'</body>'+
'</html>';
response.writeHead(200, {Content-Type: text/html});
response.write(body);
response.end();
}
function upload(response) {
console.log(Request handler 'upload' was called);
response.writeHead(200, {Content-Type: text/plain});
response.write(Hello Upload);
response.end();
}
exports.start = start;
exports.upload = upload;
And here's the stack trace:

The only answers I found anywhere were It's async so use a callback like so:
response.write(body, function(err) {
response.end();
});
...Which throws the exact same error.
Any help with this would be amazing. The few sparse answers I've found online don't help at all.
Thanks!
