How to get the file and upload it using Node.js and Postman

Question

I need one help. I am sending file using Postman and I need to upload it inside required folder using Node.js. I am explaining my code below.

server.js:

var express=require('express');
var morgan = require('morgan');
var http=require('http');
var bodyParser= require('body-parser');
var methodOverride = require('method-override');
var mongo = require('mongojs');
var session = require('express-session');
var app=module.exports=express();
var server=http.Server(app);
var port=8889;
var api=require('./api/api.js');
app.use(express.static(__dirname + '/public'));     // set the static files location /public/img will be /img for users
app.use(morgan('dev'));                     // log every request to the console
app.use(bodyParser.urlencoded({ extended: false,limit: '5mb' }))    // parse application/x-www-form-urlencoded
app.use(bodyParser.json({limit: '5mb'}))    // parse application/json
app.use(methodOverride());    
app.post('/upload',api.upload);    
server.listen(port);
console.log("Server is running on the port"+port);

api.js:

var multer  = require('multer');
var storage =multer.diskStorage({
  destination: function (req, file, callback) {
    callback(null, './../uploads');
  },
  filename: function (req, file, callback) {
    callback(null, Date.now()+'-'+file.originalname);
  }
});
var upload = multer({ storage: storage});
exports.upload=function(req,res){
}

Actually I am posting the file using postman whose screen shot is given below.

Here my requirement is the file will upload into the required folder i.e-uploads and the uploaded file name will return as response to user. Please help me.

You haven't actually used the multer here. You have created upload using multer but you did not use it.

Try the following code:

app.post('/upload', upload.single('file'), function (req, res, next) { 
     // req.file is the `file` file
     // req.body will hold the text fields, if there were any
})

where upload will be the var upload = multer({ storage: storage}); variable.
