separate file for routes in express - node.js

Question

I was wondering how do I move all of my api routes in express into a separate routes.js file from my server.js file
I have a long list of api routes using app.use() for each route. So each route is in its own file, e.g. movies.js, movie.js but when I list these it makes for a long list in server.js
So I want to remove the list of api endpoints section from the below server.js out to a routes.js file.
Here is what I have currently:
server.js
import path from 'path'
import express from 'express'
import webpack from 'webpack'
import webpackDevMiddleware from 'webpack-dev-middleware'
import webpackConfig from './webpack.config.dev'
const app = express();
/* api endpoints, can be many more, I want them in routes.js */
app.use('/api/movies', require('./src/api/routes/movies'))
app.use('/api/movie', require('./src/api/routes/movie'))
app.use(webpackDevMiddleware(webpack(webpackConfig), {
publicPath: webpackConfig.output.publicPath
}));
app.use('/public', express.static(__dirname + '/public'))
app.get('*', function(req, res) {
res.sendFile(path.join(__dirname, 'index.html'));
});
app.listen(3000, 'localhost', function (err) {
if (err) {
console.log(err);
return;
}
})
An example route
movies.js
var express = require('express');
var request = require("request");
var router = express.Router();
router.get('/', function(req, res) {
res.json({})
});
module.exports = router;

Answer 1

You can try to use the following modular approach.
Define controller files having logic per feature. e.g. movie.
movieController.js
module.exports = {
getMovie : function(req, res){
//do something
},
getMovies : function(req, res){
//do something
},
postMovie : function(req, res){
//do something
}
}
Then, reference that controller in routes files and simply plug those functions.
routes.js
var express = require('express');
var movieCtrl = require('./movieController');
var router = express.Router();
router.route('/movie').get(movieCtrl.getMovie);
router.route('/movie').post(movieCtrl.postMovie);
router.route('/movies').get(movieCtrl.getMovies);
module.exports = router;
And, in app.js, mount the routes to suitable location, e.g. /api
app.js
var routes = require('./routes');
app.use('/api', routes);
