Hi, I'm having trouble with when I store data to MySQL database I get a return in console blank.like this {}

here's route code :::app.post('/create', employeeController.create);

this is my controller code
const Employee = require('../models/employee.model');

exports.create = function(req, res) {

const new_employee = new Employee(req.body);
//handles null error
if(req.body.constructor === Object && Object.keys(req.body).length === 0){
  res.status(400).send({ error:true, message: 'Please provide all required field' });
    Employee.create(new_employee, function(err, employee) {
      if (err)
      res.json({error:false,message:"Employee added successfully!",data:employee});


this is my model code:

var db = require('../database');
//Employee object create
var Employee = function(employee){
this.name = employee.name;
this.email = employee.email;
this.position = employee.position;

Employee.create = function (newEmp, result) {
db.query("INSERT INTO employee set ?", newEmp, function (err, res) {
if(err) {
console.log("error: ", err);
result(err, null);
result(null, res.insertId);

module.exports= Employee;

my view code:

<form action="/create" enctype="multipart/form-data" method="POST">
<div class="row">
<div class="col-md-6">
<input name="name" type="text" class="form-control" required>
<div class="col-md-6">
<input name="email" type="email" class="form-control" required>
<div class="row">
<div class="col-md-6">
<label for="exampleFormControlTextarea1" class="form-label">Position</label>
<input name="position" type="text" class="form-control" required>


<button type="submit" class="btn btn-primary">Save</button>
<button type="submit" class="btn btn-primary">Cancel</button>


Im getting {} in log it means req.body is getting blank.

i have tried in app.js

app.use(express.urlencoded({limit: '100mb',extended: false }));
but its not working

@Krrunal @mohit-techdoodles what does it even mean to get a return in console blank? What is a console blank?
Also - please try narrowing your problems down a bit - e.g. check if this is a problem in your interaction between the server and the DB or between the serer and the client
@jakubiszon Im getting {} in log it means req.body is getting blank.(it means i am not getting any value from my form or html.)i need to insert the values in db
Jakub Z
@mohit-techdoodles You have used body parser in your app ( also make sure it is added to app before the post handler ) but I think it does not support multipart/form-data by default. You only need to use that enctype when posting files. Just remove the whole enctype parameter from the <form> tag and try again.
And btw. did you check if the right payload is sent from the browser? You can use your browser dev tools network tab / feature to check that.

Hi everyone
I have a Node.js question:
const readStream = fs.createReadStream(fromPath)
        const writeStream = fs.createWriteStream(toPath)
        const err = (e : Error) => console.warn('Got an error here:',e)
        readStream.on('error', err)
        writeStream.on('error', err)
        log('did I make it here??')
        writeStream.on('close', () => {
            log('How about here ?')
The first time, it always works
Every time after that, I never get to 'How about here ?'.
for some reason I can't do this operation twice
the close event only happens the first time
thanks in advance
had to do with file permissions, dont worry

Hi, everyone I'm using formidable for upload file to server but I don't know why size of uploaded files on server is fewer than before upload process approximately 0.2kb, do you know how I can be sure file did upload completely Or any solution can give me exact file size after they did upload
I would just use bash I am not sure what your purpose is but it seems like your overcomplicating it and im not sure if java is the best route for a gui application.
Hi all, just to say I've joined this as a test: it works from element.io: https://matrix.org/blog/2020/12/07/gitter-now-speaks-matrix 🎉

Hi, I am new to Node , I have created a node server which prints to a Star receipt printer fine for both USB and WIFI when run on Windows however, when I run it on a Mac version 10.13.3 the WIFI works fine but USB does nothing, the data gets to the printer queue ok but then just dissappears into the ether. On windows I use the thermal-printer module ( built from source ) which works great, but on MAC ( again built from source ) the USB does nothing so I tried the node printer module ( also built from source ) and still nothing.

I've released the alpha version of spreadsheet files importer cli: sxi. More details may be found on the package readme:

(xlsx-import-cli is part of XToolset - set of high level api tools for XLSX files).

Any feedback welcomed, any stars loved :heart: .

Hi, I am trying to run a NODE server as a windows service but when I try to start it I get error 1053, it does not respond in a timely manner. I have checked all the suggestions provided by MS including setting ServicesPipeTimeout value in registry but still same error, my bat script is as follows:
@echo off
set STS_HOME=d:\TerminalServer
set NODE_HOME=d:\Node
del %STS_HOME%/log/sts.log
start /b %NODE_HOME%\node "%STS_HOME%\terminalServer.js" > %STS_HOME%/log/sts.log
Found this which worked really well npm install -g qckwinsvc,

I'm trying to port this js to java

if (cells[i0] & W && distance[i1 = i0 - 1] === undefined) distance[i1] = d, frontier1.push(i1);

i1 is reassigned during the array reference -- what does the value of i1 in distance[i1] take?
the new val or old val?
Cells[i0] and W are both numbers, so "cells[i0] & W" performs a bitwise AND, then the "&&" evaluates the truthy of this, where only the number 1 is true -- is this correct?

Very much appreciated!

Hi All,

Can someone please help me to write a synchronized function in Node.

What I want, when multiple request trying to access same function it should be locked for one until the data has not been processed within that function.

Here is the my code:
