Node Server

First we'll make a server using node with the following code;

var http = require("http");

then

http.createServer(function(request, response) { response.writeHead(200, {"Content-Type": "text/plain"}); response.write("It's alive!"); response.end(); }).listen(3000);

Then call it with;

node server.js

Then log into heroku

heroku login

Now declare some variables;

var http = require("http"); var fs = require("fs"); var path = require("path"); var mime = require("mime");

Now make a json

{ "name" : "blog", "version" : "0.0.1", "description" : "My minimalistic blog", "dependencies" : { "mime" : "~1.2.7" } }

To install dependencies;

npm install

To make our 404 page fail;

function send404(response) { response.writeHead(404, {"Content-type" : "text/plain"}); response.write("Error 404: resource not found"); response.end(); }

To send the actual page we neeed;

function sendPage(response, filePath, fileContents) { response.writeHead(200, {"Content-type" : mime.lookup(path.basename(filePath))}); response.end(fileContents); }

To get access to the file path;

function serverWorking(response, absPath) { fs.exists(absPath, function(exists) { if (exists) { fs.readFile(absPath, function(err, data) { if (err) { send404(response) } else { sendPage(response, absPath, data); } }); } else { send404(response); } }); }

Finally we're creating the http server;

`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; serverWorking(response, absPath); });`

Finally, to run this bastard; http.createServer(<some code here>).listen(3000) var port_number = server.listen(process.env.PORT || 3000);

Remember to create some content, and then to run it locally;

node server.js
