CKEditor File Upload with Node and Express

routes:index.js

var express = require('express');
var router = express.Router();

var multipart = require('connect-multiparty');
var multipartMiddleware = multipart();

router.get('/', function(req, res) {
    res.render('index');
});

router.post('/uploader', multipartMiddleware, function(req, res) {
    var fs = require('fs');

    fs.readFile(req.files.upload.path, function (err, data) {
        var newPath = __dirname + '/../public/uploads/' + req.files.upload.name;
        fs.writeFile(newPath, data, function (err) {
            if (err) console.log({err: err});
            else {
                html = "";
                html += "<script type='text/javascript'>";
                html += "    var funcNum = " + req.query.CKEditorFuncNum + ";";
                html += "    var url     = \"/uploads/" + req.files.upload.name + "\";";
                html += "    var message = \"Uploaded file successfully\";";
                html += "";
                html += "    window.parent.CKEDITOR.tools.callFunction(funcNum, url, message);";
                html += "</script>";

                res.send(html);
            }
        });
    });
});

module.exports = router;

views:index.jade

doctype html
  body
    form
      textarea#ckeditor(name="content")
  
    script.
      CKEDITOR.replace('ckeditor', {
          filebrowserUploadUrl: '/uploader'
      });
      

I always get an error not found (404) with folder uploader in two cases: set static path and not athough i create folder in root or in public folder. Why?

Use a dot(.) after +' sign. Like this: __dirname + './../public/uploads/' + req.files.upload.name;
It will save uploaded image to public/uploads So make a directory name uploads inside public directory first.
