chain middleware functions in custom function
Your gatewayFunction1 does nothing except returns an array.Just use router.
const express = require('express');const gatewayFunction1 = express.Router();gatewayFunction1.use(middlewareFunction1, middlewareFunction2, controllerFunction);module.exports = gatewayFunction1;Then
const gatewayFunction1 = require('...'); // where you define gatewayFunction1router.post('/', gatewayFunction1);
Middleware should be a function and you are returning an array.If next function is not called it will get stuck. I don't like the whole idea combining them but I think the best way is to import all your middleware functions in one function and call them individually then use that function as your combined middleware.
