nodejs file transfer with http post

client.js

var request = require('request');
var path = require('path');
var fs = require('fs');

var filename = process.argv[2];

var target = 'http://localhost:3000/upload/' + path.basename(filename);

var rs = fs.createReadStream(filename);
var ws = request.post(target);

ws.on('drain', function () {
  console.log('drain', new Date());
  rs.resume();
});

rs.on('end', function () {
  console.log('uploaded to ' + target);
});

ws.on('error', function (err) {
  console.error('cannot send file to ' + target + ': ' + err);
});

rs.pipe(ws);

server.js

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

var app = express();

app.set('port', process.env.PORT || 3000);
app.use(express.logger('dev'));
app.use(express.methodOverride());
app.use(app.router);
app.use(express.errorHandler());

app.post('/upload/:filename', function (req, res) {
  var filename = path.basename(req.params.filename);
  filename = path.resolve(__dirname, filename);
  var dst = fs.createWriteStream(filename);
  req.pipe(dst);
  dst.on('drain', function() {
    console.log('drain', new Date());
    req.resume();
  });
  req.on('end', function () {
    res.send(200);
  });
});

http.createServer(app).listen(app.get('port'), function () {
  console.log('Express server listening on port ' + app.get('port'));
});

Thank you for sharing! 👍

Removing the following lines made the code work:
app.use(express.logger('dev'));
app.use(express.methodOverride());
app.use(app.router);
app.use(express.errorHandler());

Merci cela fonctionne chez moi

why creating an http server when express literally does that ???
