Question

I am getting process.nextTick error on this very basic example of node.js.

Can someone please figure out?
Is node not able to start listening on port 8000?

# cat nodejs.js
net = require("net");
s = net.createServer();

net.on('connection', function (c) {
c.end('hello');
});

s.listen(8000);

# node nodejs.js

node.js:201
    throw e; // process.nextTick error, or 'error' event on first tick
          ^
TypeError: Object #<Object> has no method 'on'

It seems you’re trying to capture an event on the library (net), but you should be looking at the connectionListener argument to createServer. Try this instead:

var net = require("net");

var server = net.createServer(function (c) {
  c.end('Hello!'); // Implicitly fired on 'connection'
});

server.listen(8000);
