Error running server.js, how to fix?

Question

Node.js

Why did I get an error when starting the server?

server.js

var http = require("http"),
url = require("url"),
path = require("path"),
fs = require("fs"),
port = process.argv[2] || 65535;
http.createServer(function(request, response) {
var uri = url.parse(request.url).pathname
, filename = path.join(process.cwd(), uri);
fs.exists(filename, function(exists) {
if(!exists) {
response.writeHead(404, {"Content-Type": "text/plain"});
response.write("404 Not Found\n");
response.end();
return;
}
if (fs.statSync(filename).isDirectory()) filename += '/index.html';
fs.readFile(filename, "binary", function(err, file) {
if(err) {
response.writeHead(500, {"Content-Type": "text/plain"});
response.write(err + "\n");
response.end();
return;
}
response.writeHead(200);
response.write(file, "binary");
response.end();
});
});
}).listen(parseInt(port, 65535));
console.log("Static file server running at\n => http://localhost:" + port + "/\nCTRL + C to shutdown");

Always swears on a bad port:

error port

RangeError [ERR_SOCKET_BAD_PORT]: Port should be > 0 and < 65536. Received NaN.

how to fix ?

Answer 1

listen(parseInt(port, 65535))

Which is not surprising. For any radix greater than 36, the result of parseInt is NaN, according to the specification.
An obvious typo, it is obvious that 65535 is supposed to be the default value, and not the base of the number system.
