Registering the application's routes

The routes used in configure() to register routing service are declared in the routes() function in routes.swift. You're expected to put all of your routes in this centralized place:

// File: /Sources/App/routes.swift
import Vapor

/// Register your application's routes here.
public func routes(_ router:
// Basic "Hello, world!" example
router.get("hello") { req in // [1]
return "Hello, world!"
}

// Example of configuring a controller
let todoController = TodoController() // [2]
router.get("todos", use: todoController.index) // [3]
router.post("todos", use: todoController.create) // [4]
router.delete("todos", Todo.parameter, use: todoController.delete) // [5]
}

The preceding sample code shows different ways of handling routes:

1. A basic endpoint is provided
2. TodoController is instantiated...
