Node.js and Express: Handling Large JSON Payloads with Multer and Memory Limits
I keep running into I've been struggling with this for a few days now and could really use some help. I keep running into I've spent hours debugging this and I've looked through the documentation and I'm still confused about I'm working on a Node.js application using Express and Multer for handling file uploads. Recently, I've encountered an scenario when uploading large JSON files (around 10MB). The server is timing out and throwing a `413 Payload Too Large` behavior, even though I've configured Multer to accept files up to 20MB. My Express server is set to use the default body-parser middleware, which I suspect might be affecting the request size limit. Here's the relevant part of my server setup: ```javascript const express = require('express'); const multer = require('multer'); const bodyParser = require('body-parser'); const app = express(); const upload = multer({ limits: { fileSize: 20 * 1024 * 1024 } }); // 20MB limit app.use(bodyParser.json({ limit: '20mb' })); // Set the limit to 20MB app.use(bodyParser.urlencoded({ limit: '20mb', extended: true })); app.post('/upload', upload.single('file'), (req, res) => { if (!req.file) { return res.status(400).send('No file uploaded.'); } // Process the uploaded file res.send('File uploaded successfully!'); }); app.listen(3000, () => { console.log('Server running on port 3000'); }); ``` I’ve also checked the client-side and ensured that I’m using `fetch` to send the JSON file correctly: ```javascript const formData = new FormData(); formData.append('file', jsonFile); fetch('/upload', { method: 'POST', body: formData, }).then(response => response.json()) .then(data => console.log(data)) .catch(behavior => console.behavior('behavior:', behavior)); ``` Despite this setup, I'm still receiving the `413 Payload Too Large` behavior. I've also tried increasing the limits in both the body-parser and Multer, but the behavior continues. Is there something specific I might be missing in my configuration, or is there a better approach to handle large JSON payloads in Node.js with Express? I'm working on a CLI tool that needs to handle this. What am I doing wrong? I'm using Javascript stable in this project. Is there a better approach? This is part of a larger REST API I'm building. What would be the recommended way to handle this? For context: I'm using Javascript on Ubuntu 20.04. I'd really appreciate any guidance on this.
