I am trying to upload a file to my server, but req.file and req.files is always undefined on my POST REST endpoint.
The content I'm trying to upload is a ".dat" file, and I am expecting a json response.
Here's my code:
Server side:
var express = require('express');
var multer = require('multer')
var upload = multer({ dest: 'uploads/' })
var app = express()
app.post('/creoUpload', upload.single('uploadFileField'), function(req, res, next) {
console.log("req.file = ",JSON.stringify(req.file)); //is undefined
console.log("req.files = ",JSON.stringify(req.files)); //also undefined
});
Client Side:
<form id="creoUploadForm" action="/creoUpload" enctype="multipart/form-data" method="post">
<input type='file' name='uploadFileField'><br><br>
<input type='submit' value='Upload'/>
</form>
JS:
$( "#creoUploadForm" ).submit(function( event ) {
event.preventDefault();
var formData = new FormData($(this)[0]);
$.ajax({
url: '/creoUpload',
type: 'POST',
data: formData,
async: true,
cache: false,
contentType: false,
processData: false,
success: function (returndata) {
console.log("RETURN DATA IS: ",returndata);
},
error: function (err) {
console.log("ERROR: ",err);
}
});
});
I keep playing around with the fields but it's not working.. anyone see what I'm doing wrong here?
I'm following the example from https://www.npmjs.com/package/multer

Thank you!
You are using multer as a middleware, So before entering into your function and printing it has uploaded images to storage and removes record from req.files.
There are two ways you can access req.files.
Use multer as a function stated by finw3.
Another solution is:
//CODE STARTS
var storage = multer.diskStorage({
destination: function (req, file, cb) {
cb(null, '/filepath')
},
filename: function (req, file, cb) {
let filename = 'filenametogive';
req.body.file = filename
cb(null, filename)
}
})
var upload = multer({ storage: storage })
//CODE ENDS
Now you can access files in req.body.file
