Update app.router stack by new routes before use.
npm i -S express-refresh-use
const express = require('express');
const app = express();
const refreshUse = require('express-refresh-use');
app.get('/lala', (req, res) => {
res.send('lala');
});
router = express.Router();
router.get('/lala', (req, res) => {
res.send('lolo');
})
refreshUse(app, router, '/');
app.listen('3000', () => {
console.log('Listening');
});Then when you launch a curl :
curl http://localhost:3000/lala
-> lolo
