App.js
ignore the commented lines in the below code
var express = require('express');
var path = require('path');
var http = require('http');
var app = express();
var bodyParser = require('body-parser');
/*var urlencodedParser = bodyParser.urlencoded({ extended: false });*/
app.use(bodyParser.urlencoded());
app.set('port',process.env.PORT || 3000);
app.set('views',__dirname + '/views');
app.set('view engine','jade');
/*app.use(app.router);*/
/*var people = express.Router();*/
app.use(express.static(path.join(__dirname,'public')));
/*app.get('/about',function(req,res){
res.send("about naveen");
});*/
app.post('/user',function(req,res){
res.send("requested user name" + req.body.name);
});
/*app.get('/user/:username',function(req,res){
res.send(" "+ req.params.username + " profile");
});*/
/*app.get('/',function(req,res){
res.send("hello......");
});*/
//app.use(express.static(path.join(__dirname, 'public')));
var server = http.createServer(app).listen(app.get('port'),function(){
console.log('Express server listening on port' + app.get('port'));
});
place the file index.html in the Public folder
then start
node app.js
