Controllers

Instead of specifying all of your request handling logic as closures in your route files, you might want to use "controller" classes to arrange this activity. Controllers can use a single class to bundle together similar request processing code. A UserController class, for example, may manage all user-related inbound requests, such as viewing, creating, updating, and removing users. Controllers are kept in the app/http/controllers directory by default.   

Let's take a look at a basic controller in action. It's worth noting that the controller extends the OstroJS base controller class app/http/controllers/controller:

const Controller = require('~/app/http/controllers/controller');
const User = require('~/app/models/user')

class UserController extends Controller {
    
    async show({view,params}) {
        view('user.profile', {
            'user' : await User.findOrFail(params.id)
        });
    }
}

module.exports = UserController

This controller method's route can be defined as follows:

route.get('/user/:id', 'userController::show');

The show method on the app/http/controllers/userController class method  is called when an incoming request matches the specified route URI, and the route parameters are passed to the method.
