Express: separate route and controller files

Question

I am trying to separate multiple routes and their handler logic in Express in separate files. I saw examples of directory structures, for example, in the JS tool, where separate route and controller files are used, so I'm trying to implement this approach, but I find a problem.

My server and routes are configured like this:

server.js

var express = require('express'),
  app = express(),
  bodyParser = require('body-parser'),
  routes = require('./routes/index')

app.use(bodyParser.urlencoded({extended: true}));
app.use(bodyParser.json());
routes(app);

/routes/index.js

module.exports = function(app) {
  var catalogues = require('../routes/catalogues');
  app.use('/catalogues-api', catalogues);
};

/routes/catalogues.js

var catalogues = require('../controllers/catalogues');
module.exports = function(app) {

  app.route('/catalogues')
    .get(catalogues.apiGET)
    .post(catalogues.apiPOST);
};

/controllers/catalogues.js

var request = require('request');

exports.apiGET = function(req, res) {
  var options = prepareCataloguesAPIHeaders(req);
  request(options, function(err, response, body){
    res.send(body);
  });
};

exports.apiPOST = function(req, res) {
  var options = prepareCataloguesAPIHeaders(req);
  options.json = true;
  options.body = stripBody(req.body);
  request(options, function(err, response, body){
    res.send(body);
  });
};

When I launch the application and get the GET request against / catalogs -api / catalogs, I get an error message from node:

TypeError: undefined is not a function on module.exports (C: \ Users \ rparker \ Documents \ GitHub \ testproj \ src \ server \ routes \ catalogues.js: 4: 7)

app.route /routes/catalogues.js. , , - , .

/routes/catalogues.js

var express = require('express');
var router = express.Router();
var catalogues = require('../controllers/catalogues');

router.route('/catalogues')
.get(catalogues.apiGET)
.post(catalogues.apiPOST);
module.exports = router;
