Can't connect routes in Express app

Question

I have the following structure

project

-app/

--controllers/

---home.js

--models/

---home.js

--views/

---home.html

-db/

--db.js

-index.js

my controller home.js looks like this:

var express = require('express');
var router = express.Router();
var database = require('../models/home');
var path = require('path');

router.get("/", function(request, response) {
    response.sendFile(path.join(__dirname, '../views', 'home.html'));
});

module.exports = router;

Now I want to make that route useful, so in my index.js I have:

var express = require('express');
var app = express();
var port = 3000;

app.use(require('./app/controllers/home')); //<-- this is what I ask for

app.listen(3000, function(err ) {
    //......
})

But now I have more then just route to 'home', so instead of

 app.use(require('./app/controllers/home'));
 app.use(require('./app/controllers/about'));
 app.use(require('./app/controllers/etc'));

I read that I can use:

app.use(require('./app/controllers/'));

But I get error that the module cannot be found. Can you suggest me how can I easily get all my routes in use? Thanks :)

If I understand your question right you're trying to route a router to a different relative path. You can set a relative path by passing that path as the first parameter. Then any route inside of your router that uses app.get/use/... will start from that relative path.

Inside index.js

app.use("/home", require('./app/controllers/home'));
app.use("/about", require('./app/controllers/about'));
app.use("/etc", require('./app/controllers/etc'));

inside ./app/controllers/home and other routes

router.get("/", ...) // this will be located at localhost/home
router.get("/myhouse, ...) // this will be located at localhost/home/myhouse

Also worth metioning you can route a router inside a router

router.use("/", require('path/to/another-router.js'))
