Question

I have a basic node.js setup, but I think I’m missing something.

My main.js:

var a = require('./another.js');

var http = require('http');
http.createServer(function (request, response) {
    response.writeHead(200, 
    {
        'Content-Type': 'text/html'
    });

    response.write(a.saysomething('Hi there!') + '<br />');
    response.end();
}).listen(27182);

console.log('Server running at http://127.0.0.1:27182/');

My another.js:

exports.saysomething = function (str) {
    console.log('in saysomething!');
    return str + ' hey there!';
}

The issue is that my console is outputting in saysomething! twice. Am I missing something? When I refresh the page, I expect only one in saysomething!.

Your browser is likely trying to get favicon.ico in addition to the url you are hitting. Try to just do the command on the command line: curl http://127.0.0.1:27182/

Also, you can add logging for request.url. That will show you which urls are being requested.
