How to Handle Large File Uploads with Streaming in Node.js Using Multer and Express?
I've tried everything I can think of but I keep running into I'm reviewing some code and I'm testing a new approach and I've been struggling with this for a few days now and could really use some help... I'm trying to implement a file upload feature in my Node.js application using Express and Multer, but I need to handle large files efficiently. My current setup is giving me a `413 Payload Too Large` behavior when I attempt to upload files over 10MB, which is the default limit. I've tried modifying the `limits` in Multer, but I'm still running into issues. Here’s my current code: ```javascript const express = require('express'); const multer = require('multer'); const app = express(); const storage = multer.memoryStorage(); const upload = multer({ storage: storage, limits: { fileSize: 20 * 1024 * 1024 } // 20MB limit }); app.post('/upload', upload.single('file'), (req, res) => { if (!req.file) { return res.status(400).send('No file uploaded.'); } // Handle the file (e.g., save to database, process, etc.) res.send('File uploaded successfully.'); }); app.listen(3000, () => { console.log('Server is running on port 3000'); }); ``` I've increased the file size limit in Multer, but the behavior continues when I try to upload a file larger than 10MB. Additionally, I noticed that for very large files, my application starts consuming a lot of memory. I want to ensure that the uploads are streamed efficiently without overwhelming the server's memory. I've read about using streams, but I'm not sure how to implement that properly with Multer. Can anyone provide guidance or examples on how to set this up to handle larger file uploads without hitting memory limits? This is part of a larger web app I'm building. Any ideas what could be causing this? I'd love to hear your thoughts on this. I've been using Javascript for about a year now. Could this be a known issue? I recently upgraded to Javascript 3.9. I recently upgraded to Javascript 3.10.
