如何在Node.js和Express中更好地组织路线？

Question

My WebAPI code at the moment is pretty modular I would say. But I would like it to be even more.

I have this server.js file that has all the routes, and I would like to split them into separate controllers. Any idea on how to do that? Here's an example:

app.get('/users/me', authenticate, (req, res) => {
    res.send(req.user);
});

I have a bunch of these routes in my server.js file. How would I go about creating a user-routes.js file with my user routes there? Also for all the other collections' routes I have set up.

app.post('/firm', authenticate, (req, res) => {
    var firm = new Firm({
        name: req.body.name,
        number: req.body.number,
        _creator: req.user._id
    });

    Firm.findOne({
        number: req.body.number,
        _creator: req.user._id
    }).then(firmFound => {
        if (firmFound) {
            return res.status(400).send({
                message: 'Firm with that name or number already exists.'
            })
        }
        firm.save().then((firm) => {
            res.send(firm);
        }, (e) => {
            res.status(400).send(e);
        });

    });
});

On a subfile, eg users.js you can define a new Router :

const users = Express.Router();

users.get("/me", () => "whatever");

module.exports = users;

That applies to all your subroutes and even subsubroutes. Then on the higher instance you just need to mount that subroutes under their path (server.js for example):

app.use("/users/", require("users.js"));
