How to modularize routing with Node.js Express


How to modularize routing with Node.js Express

With these it helps You should use the native express router, it was made to solve this exact problem! It essentially lets you create simplified nested routes in a modular way.
For each of your resources, you should separate out your routes into several modules named .js. Those modules would contain all of the routing code as well as any other configuration or necessary functions. Then you would attach them in index.js with:
code :
var apiRoute = router.route('/api')
apiRoute.use('/< yourResource >', yourResourceRouter)
var apiRoute = router.route('/api')
  , bikeRoutes = require('./bikes')

apiRoute.use('/bikes', bikeRoutes)
var express = require('express')
  , router = express.Router()
  , bikeRoutes = router.route('/')

bikeRoutes.get(function (req, res) {
    res.send('api GET request received')
});

module.exports = bikeRoutes
var apiRoute = router.route('/api')
  , bikeRoutes = require('./bikes')
  , carRoutes = require('./cars')
  , skateboardRoutes = require('./skateboards')
  , rollerskateRoutes = require('./rollerskates')

// routes
apiRoute.use('/bikes', bikeRoutes)
apiRoute.use('/cars',  carRoutes)
apiRoute.use('/skateboards', skateboardRoutes)
apiRoute.use('/rollerskates', rollerskateRoutes)

With these it helps I'm trying to modularize my node.js application (using express framework). The trouble I am having is when setting up my routes. , A better approach:
Create a routes.js file that contains:
code :
var index = require('./controllers/index');

module.exports = function(app) {
  app.all('/', index.index);
}
require('./routes')(app);

I wish this helpful for you Since you mounted the about router on /about via app.use('/about', about);, you would need to change
code :
router.get('/about', function(req, res, next) {
  res.render('about');
});
router.get('/', function(req, res, next) {
  res.render('about');
});

hope this fix your issue You're not calling the app.listen() function. Instead of the http.createServer one, you should invoke the Express function.
Please, take a look at a basic example.
code :
app.listen(3000, function () {
  console.log('Example app listening on port 3000!');
});
http.createServer(app).listen(port, function(){ 
    console.log('now listening on port ' + port);
});

I hope this helps you . Router.use() expects an instance of another Router. However your (non-working) module only returns a function.
Use this in your index.js to fix the issue:
code :
router.use('/users', require('./users')());

this will help The error message indicates that usdHkd's parent variable in undefined. Most probably, this error is coming from business.usdHkd in business.usdHkd = req.body.business.usdHkd; (you can confirm it by adding more console.log() lines around this line and checking the outputs).
If business.usdHkd = req.body.business.usdHkd; is giving error, that means, business is undefined. However, you don't need this line as business is already updated by findByIdAndUpdate.
code :
//Business Update
async remittanceCreate (req, res, next) {

    let business = await Business.findByIdAndUpdate(req.params.id, req.body.business);
    console.log(business);

    // Below code is not required since findByIdAndUpdate() will update your model
    /*
    //update the post with any new properties
    business.usdHkd = req.body.business.usdHkd;
    business.hkdUsd = req.body.business.hkdUsd;
    business.rateCreatedAt = req.body.business.rateCreatedAt;

    //save the updated post in the db
    business.save();
    */

    //redirect to show page
    res.redirect(`/business/${business.id}`);
},
let business = await Business.findByIdAndUpdate(req.params.id, req.body.business, {new: true});
