How to reload one file on Express without restarting?
You can use require-reload to do that. You should have a file where you import the router.js module, to which you are appending new code, that should look like:
var reload = require('require-reload')(require),var router = reload('router.js');Each time you append new code you should do:
try { router = reload('router.js');} catch (e) { console.error("Failed to reload router.js! Error: ", e);}The express-route-refresh module may come in handy too. In fact, internally it also uses require-reload.
