[Express.js] Timeout Configuration Changes and Sample Code for Testing
I’ll introduce Express.js default timeout and how to change timeout settings with sample code.
I wondered “What’s Express default timeout in ms again?” so I checked the Node.js official documentation.
I also wrote sample code to test Express timeout behavior, which I’ll describe below.
Timeout in milliseconds. Default: 120000 (2 minutes).Quote from: server.timeout - HTTP | Node.js v12.13.0 Documentation
