Upload and resize images with AngularJS. Proof of Concept.

var express = require('express');
var http    = require('http');
var path    = require('path');
var fs      = require('fs');


var app = express();

/*
  it is expected that this app is run from the root dir via 
  `node demo/back-end/app.js`
*/

var image_download_dir = '../demo/back-end/images/';
var front_end_dir = '../demo/front-end/';

app.configure(function() {
  app.set('port', process.env.PORT || 8080);
  app.use(express.bodyParser());
  app.use(express.static(path.join(__dirname, image_download_dir)));    
});


app.get('/', function(req, res){
  res.sendfile(__dirname + front_end_dir + 'demo.html');
});

app.post('/upload', function(req, res) {
  var image =  req.files.image;
  var newImageLocation = path.join(__dirname, image_download_dir , image.name);
  
  fs.readFile(image.path, function(err, data) {
    fs.writeFile(newImageLocation, data, function(err) {

        src: 'images/' + image.name,
        size: image.size
      });
    });
  });
});

http.createServer(app).listen(app.get('port'), function() {
  console.log("imageupload demo running on port " + app.get('port'));
});
