Node.js Express Server Crashes on Large JSON Array Input with body-parser

node.js express body-parser json JavaScript

I'm not sure how to approach I recently switched to I'm stuck on something that should probably be simple... I'm writing unit tests and I've been banging my head against this for hours. My Node.js application is crashing when I try to send a large JSON array to my Express server. I'm using the `body-parser` middleware to handle incoming requests. The server works fine for smaller payloads but throws an behavior when I send a JSON object with around 10,000 entries. The behavior I encounter is: ``` behavior: Request entity too large at readStream (node_modules/body-parser/lib/read.js:123:15) at invokeCallback (node_modules/body-parser/lib/read.js:64:7) ``` I've tried increasing the limit in the body-parser configuration like this: ```javascript const express = require('express'); const bodyParser = require('body-parser'); const app = express(); app.use(bodyParser.json({ limit: '50mb' })); // Increasing the limit to 50mb app.use(bodyParser.urlencoded({ extended: true })); app.post('/api/data', (req, res) => { console.log(req.body); res.status(200).send('Data received!'); }); app.listen(3000, () => { console.log('Server is running on port 3000'); }); ``` Despite this configuration, the server still crashes with the same behavior. I also checked my Node.js version and I'm currently using v16.13.0. Is there something I'm missing with the body-parser settings, or is there a better approach to handle large JSON payloads? Any insights or recommendations would be greatly appreciated! For reference, this is a production application. Any ideas how to fix this? This is happening in both development and production on Debian. I'd be grateful for any help. I've been using Javascript for about a year now. Thanks for your help in advance!
