Node.js File Upload with Multer Not Handling Large Files Gracefully

node.js express multer JavaScript

I'm dealing with I'm not sure how to approach I've looked through the documentation and I'm still confused about I'm working on a Node.js application using Express and the Multer library to handle file uploads. I've set it up to allow users to upload images, but I'm working with issues when trying to upload larger files (over 5MB). The uploads sometimes unexpected result, and I occasionally see the following behavior in my console: ``` behavior: ENOSPC: no space left on device, write ``` This happens even though I'm sure there’s enough space on the server. I’ve configured Multer as follows: ```javascript const express = require('express'); const multer = require('multer'); const app = express(); const storage = multer.diskStorage({ destination: (req, file, cb) => { cb(null, 'uploads/'); }, filename: (req, file, cb) => { cb(null, Date.now() + '-' + file.originalname); } }); const upload = multer({ storage: storage, limits: { fileSize: 5 * 1024 * 1024 } // 5MB }); app.post('/upload', upload.single('image'), (req, res) => { res.send('File uploaded successfully!'); }); app.listen(3000, () => { console.log('Server started on port 3000'); }); ``` I've verified that the destination folder exists and has the correct permissions. I also tried increasing the file size limit in Multer, but that only led to more instances of the behavior. Additionally, I checked disk usage with `df -h`, and it shows that I have plenty of available space. Is there a known scenario with Multer or Node.js when handling larger file uploads, or could this be related to my server setup? Any insights or suggestions on how to troubleshoot this would be greatly appreciated! Any ideas what could be causing this? I've been using Javascript for about a year now. Has anyone dealt with something similar? This is for a REST API running on Windows 11. How would you solve this?
