Question
Can't Serve Static Files using Node.js over port 3000
This may be an insanely stupid question, even for a node.js newbie. I set up a droplet running 64-bit Ubuntu and installed all of the requisite Node.js packages. I am building a chatroom application using the Node.js in Action book. For this project, I created an HTTP server for serving static content. For some reason, I am able to hit the server over port 3000 (and get a 404 error message), but I can't seem to serve the static content that I created in the public directory (i.e. index.html file). Below is the server and the index.html file. Can anyone give me a clue why the content is not being served? Assume all the files are in their correct directory locations on the server.
Server:
var http = require('http');
var fs = require('fs');
var path = require('path');
var mime = require('mime');
var 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(
200,
{"content-type": mime.lookup(path.basename(filepath))}
);
response.end(fileContents);
}
function serveStatic(response, cache, absPath) {
if (cache[absPath]) {
sendFile(response, absPath, cache[absPath]);
} else {
fs.exists(absPath, function(exists) {
if (exists) {
fs.readFile(absPath, function(err, data) {
if (err) {
send404(response);
} else {
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;
}
var absPath = './' + filePath;
serveStatic(response, cache, absPath);
});
server.listen(3000, function() {
console.log("Server listening on port 3000.");
});
