I am coming from a (traditional) server side scripting (PHP) background and am trying to experiment with Node to see what the fuss is all about.
Objective: serve up a simple web document with some style sheets and scripts on it.
My node.js script:
var http = require('http');
var fs = require('fs');
fs.readFile('index.html', function (err, html) {
if (err) {
throw err;
}
http.createServer(function(request, response) {
response.writeHeader(200, {"Content-Type": "text/html"});
response.write(html);
response.end();
}).listen(1337, '127.0.0.1');
});
index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset='utf-8'>
<title>Node.js test</title>
<link rel="stylesheet" media="screen" type="text/css" href="css/plugin.css" />
<link rel="stylesheet" media="screen" type="text/css" href="css/xGrid.css" />
<link rel="stylesheet" media="screen" type="text/css" href="css/jquery-ui/jquery-ui-1.10.1.custom.min.css" />
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.6/jquery.min.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/jqueryui/1.8/jquery-ui.min.js"></script>
<script src="js/slate.js"></script>
<script src="js/slate.portlet.js"></script>
<script src="js/slate.message.js"></script>
<script src="js/plugin.js"></script>
</head>
<body>
<h1 class="styled-h1">Test</h1>
</body>
</html>
The problem I am facing:
The two script includes coming from the Google CDN are loaded on to the document fine. However, every other style sheet or script being called from my local file system get interpreted as text/html and so don't have the intended effect. Here is a screenshot from Google Chrome console:
I want to understand why this is happening.
PS: I know I can use a framework like Express to make things easier but I want to get a hold of the fundamentals first.

Css files will be stored in public folder. const http = require('http'); const path = require('path'); const express = require('express'); const bodyParser = require('body-parser'); const route = require('./routes'); const app = express(); app. use(bodyParser.
Simple: you're setting the Content-Type header to text/html, always. Also, it will always serve your index.html file. Look:
fs.readFile('index.html', function (err, html) {
if (err) {
throw err;
}
http.createServer(function(request, response) {
response.writeHeader(200, {"Content-Type": "text/html"}); // <-- HERE!
response.write(html); // <-- HERE!
response.end();
}).listen(1337, '127.0.0.1');
});
You should parse the URL, look up what file you want to require, read its contents and write them to the response if it exists, otherwise serve an 404 error. Also, you'll need to set the correct headers.
So, do you still want to do it at your own?
At least, try something like send, which is a basic static file server.

Rather than pointing contentType to text/html, You can do some thing like this using path module
var filePath = req.url;
if (filePath == '/')
filePath = '/index.html';
filePath = __dirname+filePath;
var extname = path.extname(filePath);
var contentType = 'text/html';
switch (extname) {
case '.js':
contentType = 'text/javascript';
break;
case '.css':
contentType = 'text/css';
break;
}
fs.exists(filePath, function(exists) {
if (exists) {
fs.readFile(filePath, function(error, content) {
if (error) {
res.writeHead(500);
res.end();
}
else {
res.writeHead(200, { 'Content-Type': contentType });
res.end(content, 'utf-8');
}
});
}
