This is a very simple tutorial, how to upload files to the nodejs server.
For this we need module "express-fileupload" which acts as a middleware for the express module.

This code is only working for single file upload and if we try to upload multiple files we face an error saying file.mv() is not a function Is there any solution for this?

@Aman Kharbanda tried that too using a for loop still when clicked on Submit button the page keeps loading and nothing else happens.
Aman Kharbanda
Aman Kharbanda 5 days ago
In that case you will have an array of object, run a loop and upload the files individually.

David Fraga

I'm not using React, but I'm trying to do something similar. I'd like to upload the file and then make it available as a download link after the page reloads, but with a custom file name that can be provided form a different text field.

How could I do this but then parse an XML file that I uploaded? I've been parsing XML data with node and want to make a file uploader that parses my xml files.
Aman Kharbanda
Hello there. if the xml parser module you are using requires a file path, then you already have the path when you are saving it....else you can use req.files.foo.data.toString() which can be used by the parser.

When i try to run node.js on my cmd directory where the app.js is stored, it says cannot find module 'express'
Brenna Leonard
Make sure to run "npm install module_name" in the command line for any module you are using in your node app.
Aman Kharbanda
hello there! you are getting this error because the express module is not installed. So you need to use the "npm install express" to install the required module. It is recommended to use the "npm init" to create a package.json file interactively that contains information about the application like dependencies, author name, package name etc. and then use the previous command with "--save" flag = "npm install express --save" to add the package and in the list of dependencies. Hope this helps

Gururaj Moger

for this u can checkout my github working repository. (github.com/guru9)
Aman Kharbanda
Aman Kharbanda 2 years ago
when you recieve the data... you need to make sure that it is in the same format beacuse we have already defined the schema. So we can use mongodb insertMany to insert the array of records, alternatively you can loop through each record and insert it. sorry for replying so late.

Aman Kharbanda

yes you need to use this command to install the module. npm install express-fileupload Then you need to only use this module for fileupload.

Aman Kharbanda
Aman Kharbanda 2 years ago
maybe you haven't configured the express-fileupload middleware. var upload = require('express-fileupload') app.use(upload()) // important you can check this source code : jsfiddle.net/kharbanda14/kpwpqvma/

thank u for responding. but how to show all image that was uploaded
Aman Kharbanda

if you know the url then it would be very easy to show. For eg if you upload the file to assets folder then var path = '/asset/filename.jpg' var image = '' res.send(image) I hope this helps.

we can also change the filenames(safe filenames) or even encrypt the files that are stored on the server.

nice video. I have a question. I want to send a file from one server to other. How do I do that?

Great .... using encryption is better, you can set the keys on both the server/computers to encrypt and decrypt the files.

As a part of my assignment, I need to incorporate a security tool in addition to transfering files. So what I am doing is using the npm module caesar-ciphers to encrypt data and then send. That is why I was inclined towards simple http
Aman Kharbanda
Aman Kharbanda 2 years ago
If you want to stick with simple http, then it's alright. But the thing is anyone can transfer files to the server. You can use a key that can be sent through the url to validate upload.
Anfield
Anfield 2 years ago
If I want to use simple http, then does it make sense what I have done? As I said in a previous comment, I have sent a http request(containing the file) from one computer to other. On the other computer, I am using a post request to get the file. Is there a better way?
