How do you set maxSockets in Node.js when using Express?

Question

Is there a way to modify the Node.js maxSockets setting when using the Express framework?

Answer 1

Somewhere after you do var http = require('http'), just add http.globalAgent.maxSockets = x (where 'x' is the number of sockets you want).

Please note that if you are making requests over https, you will need to set maxSockets for https as well.

var https = require('https');
https.globalAgent.maxSockets = your_val_here;

Answer 2

From version v0.12.0 maxSockets set to Infinity

maxSockets are no longer limited to 5. The default is now set to Infinity with the developer and the operating system given control over how many simultaneous connections an application can keep open to a given host.
