How to use Node.js and in particular Express to handle uploaded files

In how to upload a file using Fetch I explained how to upload a file to a server using Fetch.

In this post I’m going to show you part 2: how to use Node.js, and in particular Express, to handle uploaded files.

Install the express-fileupload npm module:

npm install express-fileupload

and add it to your middleware:

import fileupload from 'express-fileupload'


const fileupload = require('express-fileupload')

After you created your Express app, add:


This is needed because otherwise the server can’t parse file uploads.

Now uploaded files are provided in req.files. If you forget to add that middleware, req.files would be undefined.'/saveImage', (req, res) => {
  const image = req.files.myFile
  const path = __dirname + '/images/' +, (error) => {
    if (error) {
      res.writeHead(500, {
        'Content-Type': 'application/json'
      res.end(JSON.stringify({ status: 'error', message: error }))

    res.writeHead(200, {
      'Content-Type': 'application/json'
    res.end(JSON.stringify({ status: 'success', path: '/images/' + }))

This is the smallest amount of code needed to handle files.

We call the mv property of the uploaded image. That is provided to us by the express-fileupload module. We move it to path and then we communicate the success (or an error!) back to the client.

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching May 21, 2024. Join the waiting list!
