Node.js Expressjs error, payload too large

I have some error
using Node.js + expressjs

Error message : payload too large

Detail message (on front-end browser):
Failed to load resource: the server responded with a status of 413 (Payload Too Large)

This error can fix it with simple code.

add limit option to
bodyParser.json({})
bodyParser.urlencoded({})

app.use(bodyParser.json({limit: '50mb'})); app.use(bodyParser.urlencoded({ extended: false, limit: '50mb' }));

I hope you save time

Node.js Express4 make https server

Make https server using Node.js + Expressjs v4

1. Make expressjs project

$express https_server
$cd https_server && npm install

2. Make cert, key file

$openssl genrsa 1024 > key.pem

using this key.pem file, make cert file.

$openssl req -x509 -new -key key.pem > cert.pem

Insert these data.

- Country Name
- State or Province Name
- Locality Name
- Organization Name
- Organization Unit Name
- Common Name
- Email Address

cert, key file ready to make https server.

3. Edit server code
(bin/www file code)

	var app2 = require('../app');
	var https_port = 443;
	var port2 = normalizePort(process.env.PORT || https_port);
	app2.set('port', port2);
	var https_server = https.createServer(options, app2);
	https_server.listen(port2);
	//https server added

(if you occur error, please run on root)

Good luck!
