I'm trying to store an uploaded file,the file reached the server successfully but don't know how to store it using the multiparty library that's the code:
var multipart = require('connect-multiparty');
var multipartMiddleware = multipart();
app.post('/upload_audio', multipartMiddleware, function(req, resp) {
console.log(req.body, req.files);
if(req.files){
resp.status(200).send("Uploaded!!!");
}
});
By default the 'connect-multipart' module save the file in a default file which is
"C://Users//ur-username//AppData//Local//Temp" but you can change it by adding this line :
app.use(multipart({ uploadDir: "ur_path"}));

I have 2 nodeJS services and I would want to upload file in a dir, from one NodeJS (backend) to another NodeJS(backend). The receiver nodeJS is an express app.
Looking for some working code sample.
PS: Couldn't find any code samples in search, since everywhere it was Multer from client to server uploads that receives multipart/form-data.
Uploading file using POST request in Node.js
Receive the file first as you correctly said using Multer. Then, you may either save the file to a temporary directory before uploading it again or just send the file as-is.
You need to setup a server running with Multer on the 2nd server that wishes to receive the file.
const express = require('express');
const app = express();
const upload = multer({ dest: 'files/' });
app.post('/upload', upload.single('file'), (req, res) => {
res.sendStatus(200);
});
app.listen(3001);
Then on the server you wish to send the file from, do something like this:
const request = require('request');
const req = request.post('localhost:3001/upload', (err, res, body) => {
if (err) throw new Error(err);
if (res && res.statusCode == 200) {
console.log('Success');
} else {
console.log('Error');
};
});
const form = req.form();
form.append('file', fs.createReadStream('./location/to/file'));
I'm having a headache trying to upload files to a Node server from an Angular 6 app. I have the following route handler in the Node app:
var express = require('express');
var router = express.Router();
// Route for /fileupload
//****************************************************************
// Multer module for uploading files
var multer = require('multer');
// set the directory for the uploads to the uploaded to
var DIR = './uploads/';
var upload = multer({ dest: DIR }).single('cloudImg');
router.post('/', (req, res, next) => {
var path = '';
upload(req, res, function(err) {
console.log('REQ HEADER', req.headers);
if (err) {
// An error occurred when uploading
console.log(err);
return res.status(422).send("an Error occured")
}
// No error occured.
path = req.file.path;
return res.send("Upload Completed for " + path);
});
});
module.exports = router;
I use the multer module for uploading the file. If I call the API from Postman, everything works fine:
But if I send the file from the Angular app, the Node server crashes giving this error: TypeError: Cannot read property 'path' of undefined.
I've realised that Postman sets this content-type header:
'content-type': 'multipart/form-data; boundary=--------------------------719034023986440712074389'
I'm pretty sure that the error happens because the Node server is expecting another type of data and it can't create the req.file object. I know how to set the content-type header, but how could I generate the boundary field? Or, is there any way to tell Angular httpClient methods to autogenerate the header for this case?
Thanks,
Is there a way to extract file from http req without saving it on server ?
as there are some parser like Multer and Multiply , but they save file on server location first.
Can we parse file in node.js as we do in c# .Net
Request.Files
Resolved by using Multer in memory storage mode.
Like:-
var storage = multer.memoryStorage();
var upload = multer({ storage: storage });
this will keep file in buffer
and you can extract file like this
app.post('/upload', upload.any(), function(req, res) {
console.log(req.files);
});
I have a xmlhttprequest which uploads the file and I am trying to receive it in my node-express server. but for some reason I am not able to retrieve the file content in the server. Not sure where I am missing it.
app.post('/api/uploadfiles', function(req, res) {
console.log("apicalled");
console.log(req);
console.log(req.body);
console.log(req.files);
console.log(JSON.stringify(req.files));
});
In order for you to see the files, you will need to add another middleware that parses multi-part request.
Try using connect-multiparty module like so:
var multipart = require('connect-multiparty'); //for files upload
var multipartMiddleware = multipart();//for files upload
app.post('/api/uploadfiles', multipartMiddleware, function(req, res) {
console.log("apicalled");
console.log(req);
console.log(req.body);
console.log(req.files);
console.log(JSON.stringify(req.files));
});
I am able to upload images using Node.Js and Multer. The images are saving in encrypted format with random names. How can I retrieve and display images in a .jade file or .hetml file?
//My Code to upload image
router.post("/upload", function(req, res, next){
if (req.files) {
console.log(util.inspect(req.files));
if (req.files.myFile.size === 0) {
return next(new Error("Hey, first would you select a file?"));
}
fs.exists(req.files.myFile.path, function(exists) {
if(exists) {
res.end("Got your file!");
} else {
res.end("Well, there is no magic for those who don’t believe in it!");
}
});
}
});
// Upload page (Jade file)
form#fileUpload(method="post" action="/uploads/upload" enctype="multipart/form-data")
label(for="payload") Select a file to upload:
input#fileToUpload(type='file', name='myFile')
//input#payload(type="file" name="myFile" accept="image/*")
br
button#upload Upload
var multer = require('multer'),
upload = multer({dest: 'uploads/'});
app.post('/multipart-upload', upload.single('file'), function(req, res){
var filename = req.file.path;
console.log('Uploading File: ' + JSON.stringify(req.file));
});
Multer needs a path to upload the file. You can keep the path inside the public/static folder of express, and directly link the file.
Or You can use the static files middleware to serve the files in the upload folder and directly link them.
app.use('/image-uploads', express.static('uploads'));
