Handling large JSON payloads in Node.js with Express and avoiding server crashes
I'm relatively new to this, so bear with me. I've searched everywhere and can't find a clear answer. I'm working with a serious scenario when trying to process large JSON payloads in my Node.js application using Express. The application throws a `PayloadTooLargeError` when I attempt to send JSON data that exceeds the default limit. I have tried increasing the payload limit using the `body-parser` middleware with `app.use(bodyParser.json({ limit: '10mb' }));`, but even after adjusting the limit, I'm still experiencing performance degradation and occasional crashes due to memory overload. Here’s a snippet of how I set up my Express server: ```javascript const express = require('express'); const bodyParser = require('body-parser'); const app = express(); app.use(bodyParser.json({ limit: '10mb' })); app.post('/upload', (req, res) => { // Process incoming JSON here console.log(req.body); res.send('Data received!'); }); app.listen(3000, () => { console.log('Server is running on port 3000'); }); ``` I’ve also tried switching to the built-in Express JSON parser by replacing `body-parser` with `app.use(express.json({ limit: '10mb' }));`, but the behavior remains the same. The payloads I’m dealing with can sometimes be over 15MB, and I’m worried about how to handle them without crashing the server. I’m not sure if it’s a good idea to increase the limit beyond 10MB or if I should implement some form of streaming or chunking for the incoming data. Is there a recommended approach for effectively managing large JSON payloads in a Node.js application without compromising performance or stability? Any insights or best practices would be greatly appreciated. This is part of a larger API I'm building. Any ideas what could be causing this? How would you solve this?
