implementing Node.js Buffer Size Configuration Causing Memory Leaks During File Uploads
I'm relatively new to this, so bear with me. I'm working through a tutorial and I'm following best practices but After trying multiple solutions online, I still can't figure this out... I'm sure I'm missing something obvious here, but I'm experiencing memory leaks when handling large file uploads in my Node.js application using the `multer` middleware for file uploads. The application is built with Express 4.17.1 and runs on Node.js 14.x. I've set a custom buffer size to optimize the upload process, but I keep running into issues where the server memory usage climbs steadily until it crashes. Here’s the relevant part of my upload configuration: ```javascript const express = require('express'); const multer = require('multer'); const app = express(); const storage = multer.memoryStorage(); const upload = multer({ storage: storage, limits: { fileSize: 10 * 1024 * 1024 } // 10 MB }); app.post('/upload', upload.single('file'), (req, res) => { console.log(req.file); // Process the file res.send('File uploaded successfully!'); }); app.listen(3000, () => { console.log('Server running on port 3000'); }); ``` I've monitored the memory usage using Node.js built-in tools and it appears to spike significantly during file uploads, especially when uploading files close to the size limit. I suspect it might be related to how the buffer is being handled in memory, but I haven’t been able to pinpoint the exact cause. What steps can I take to manage buffer sizes more effectively, or are there best practices for handling large file uploads in Node.js to prevent memory leaks? Any insights on configurations or middleware that could help would be greatly appreciated. My development environment is Ubuntu. Thanks in advance! Any ideas what could be causing this? This is for a REST API running on Windows 11. What am I doing wrong? Thanks for taking the time to read this! Thanks for any help you can provide! I'm on Ubuntu 20.04 using the latest version of Javascript. I'd be grateful for any help. Thanks for your help in advance!
