I am starting out with learning Node.js development, and I have a small
problem when it comes to running my code. I am using OS X Mountain Lion for
my development, and have a very basic Node.js app that I want to run. The
app consists of several files, one is a pure HTML file, one CSS stylesheet
and a server.js file. The contents of server.js are the following:
var http = require('http')
, fs = require('fs')
, path = require('path')
, mime = require('mime')
, cache = {};
function send404(response) {
response.writeHead(404, {'Content-Type': 'text/plain'});
response.write('Error 404: resource not found.');
response.end();
}
function sendFile(response, filePath, fileContents) {
response.writeHead(
'content-type',
mime.lookup(path.basename(filePath))
);
response.end(fileContents);
}
function serveStatic(response, cache, absPath) {
if (cache[absPath]) {
sendFile(response, absPath, cache[absPath]);
} else {
path.exists(absPath, function(exists) {
if (exists) {
fs.readFile(absPath, function(err, data) {
cache[absPath] = data;
sendFile(response, absPath, data);
});
} else {
send404(response);
}
});
}
}
var server = http.createServer(function(request, response) {
var filePath = false;
if (request.url == '/') {
filePath = 'public/index.html';
} else {
filePath = 'public' + request.url;
}
if (!filePath) {
send404(response);
} else {
var absPath = './' + filePath;
serveStatic(response, cache, absPath);
}
});
server.listen(3000, function() {
console.log("Server listening on port 3000.");
});
I guess I don't need to disclose my HTML and CSS file contents. Now, when I
try to run this app, I get the following response from the browser:
HTTP/1.1 content-type text/html
Date: Thu, 15 Nov 2012 15:19:09 GMT
Connection: keep-alive
Transfer-Encoding: chunked
How do I solve this? The index.html page doesn't get rendered and I get the above response instead. Thanks in advance for help.
