How to handle FormData from express 4

Question

I tried sending some form data to my node server but req.body has none of my form fields the node side

 var express = require('express') var app = express() var path = require('path') var bodyParser = require('body-parser') app.use(bodyParser.urlencoded({   extended: true }));  app.get('/', function (req, res) {   res.sendFile('index.html') }) app.post('/sendmail', function (req, res) {    const formData = req.body.formData 

this is what I'm sending from the browser

fetch('/send', {   method: 'POST',   body: new FormData(form) }) 

in dev tools I only see the data passed in the Referer, maybe that is my issue

body-parser doesn't handle multipart bodies, which is what FormData is submitted as.

Instead, use a module like multer.

For example, to retrieve the (regular) fields of a request:

const multer = require('multer'); const upload = multer();  app.post('/send', upload.none(), (req, res) => {   const formData = req.body;   console.log('form data', formData);   res.sendStatus(200); });
