使用Node.js在WAMP服务器中查看文件

I need to watch a file in WAMP Server, so that when the file changes the javascript can run a function.

I have done some search and saw the library Node.js, but I am having a problem to use in wamp server. I ran the setup of Node.js to install in my computer. But when I call this in my webpage:

var fs = require('fs');                                                                        

            console.log('Watching watcher.txt');

            fs.watchFile('watcher.txt', function(curr,prev) {
                console.log('current mtime: ' +curr.mtime);
                console.log('previous mtime: '+prev.mtime);
                if (curr.mtime == prev.mtime) {
                    console.log('mtime equal');
                } else {
                    console.log('mtime not equal');
                }   
            });

I get this error: "Uncaught ReferenceError: require is not defined".

Can someone help me? The Node.js in Wamp Server is doing a lot of confusion in my head.

    I have found the solution. With that simple code and don't need to install any library in WAMP Server.

    Solution: Is it possible to retrieve the last modified date of a file using Javascript?
