var express = require('express'); 
 
var app = express(); 
 

 

 
var fs = require("fs"); 
 
var bodyParser = require('body-parser') 
 
app.use(bodyParser.json());  // to support JSON-encoded bodies 
 
app.use(bodyParser.urlencoded({  // to support URL-encoded bodies 
 
    extended: true 
 
})); 
 

 

 

 

 

 

 

 

 

 
app.get('*', function (req, res) { 
 
    console.log(req.path); 
 
    var path = req.path; 
 
    if(req.path == '/'){ 
 
    res.sendFile(__dirname + "/" + "index.html"); 
 
    }else 
 
    { 
 
    res.sendFile(__dirname + req.path); 
 
    } 
 
}); 
 
app.post('/app',function (req, res) { 
 
    console.log(req.body) 
 
    var action = req.body.action; 
 
    var data = req.body.data; 
 
    var fname = req.body.fileName; 
 
switch(action) { 
 
    
 
    case 'upLoad': 
 
     function decodeBase64Image(dataString) { 
 
       var matches = dataString.match(/^data:([A-Za-z-+\/]+);base64,(.+)$/), 
 
      response = {}; 
 

 
     if (matches.length !== 3) { 
 
      return new Error('Invalid input string'); 
 
     } 
 

 
     response.type = matches[1]; 
 
     response.data = new Buffer(matches[2], 'base64'); 
 

 
     return response; 
 
     }; 
 
     var imageBuffer = decodeBase64Image(data); 
 
     var newPath = __dirname + "/app/images/" + fname; 
 
     fs.writeFile(newPath, imageBuffer.data, function(err) { 
 
       res.send({confirm : "uploaded" , filename:fname }); 
 
      }); 
 
    
 
    default: 
 
     
 
} 
 
}) 
 

 

 

 
var server = app.listen(8080, function() { 
 
    var host = server.address().address 
 
    var port = server.address().port 
 
    console.log("Example app listening at http://%s:%s", host, port) 
 
})
