In this tutorial I will give you simple example of node js with express js file upload with multer. we can use Multer module for file uploading to the server. Multer is a node.js middleware which is used for handling multipart/form-data, which is mostly used library for uploading files.

Visit Multer Package : Install Multer Module

So, example of file upload in node js and express js using multer. let's start.

In this step create node application using below command

mkdir express_js_file_upload

cd express_js_file_upload

npm init



Step 2 : Install Embedded JavaScript templates (ejs)

 In this step we install ejs using below command

npm install ejs


Step 3 : Install express.js in App

Now install Express in the express_js_file_upload directory and save it in the dependencies list. For example:

$ npm install express --save

        <input type="file" name="pic" required/> <br>
        <input type="submit" value="submit"> 


Step 6 : Create index.js file

now create index.js file in your app directory. and copy below code in index.js file

const express = require("express")
const path = require("path")
const multer = require("multer")
const app = express()
app.set("view engine","ejs")
var storage = multer.diskStorage({
    destination: function (req, file, cb) {          
        cb(null, "uploads")
    filename: function (req, file, cb) {
      cb(null, file.fieldname + "-" +".jpg")
const maxSize = 1 * 1000 * 1000;
var upload = multer({ 
    storage: storage,
    limits: { fileSize: maxSize },
    fileFilter: function (req, file, cb){
        var filetypes = /jpeg|jpg|png/;
        var mimetype = filetypes.test(file.mimetype);
        var extname = filetypes.test(path.extname(
        if (mimetype && extname) {
            return cb(null, true);
        cb("Error: File upload only supports the "
                + "following filetypes - " + filetypes);
})"/uploadFile",function (req, res, next) {
    upload(req,res,function(err) {
        if(err) {            
        else {
