now.js file => replace fileServer with "fs"?

[christianstrang]

If I run the "quick example" from here: http://nowjs.com/doc/example I
receive the error "cannot find module .fileServer" which is linked in
the now.js file.
Do I have to replace "fileServer" with "fs" or did I install node.js
wrong? Is fileServer a module which is installed together with Now?

Hi christian,

fileServer is part of the NowJS library package. How did you install NowJS? If you used npm, and ran the command `npm install now` then fileServer should've automatically been included.

Mh.. here is how I installed it and what I got:

Hmm that looks correct. Can you send me the output the code of your program?

This is my code in the server.js file (which lies in /var/www/virtual/
domain.com/htdocs/helloworld):

var html = require('fs').readFileSync(__dirname+'/index.html');
var server = require('http').createServer(function(req, res){
res.end(html);
});
server.listen(8080);

var nowjs = require("../now"); //the now.js file is one folder up
var everyone = nowjs.initialize(server);

everyone.now.distributeMessage = function(message){
everyone.now.receiveMessage(this.now.name, message);
};

If I call "node server.js" I receive the following output:

node.js:201
throw e; // process.nextTick error, or 'error' event on first
tick
^

Hi Christian,

Once you npm install now, you no longer need to require the relative path to the now folder, but rather the keyword now.

So your code should look like `var nowjs = require('now');`

Note that you must run your node server from the same folder that you ran `npm install now`
