Hapi.js Simple REST API

const Hapi = require('@hapi/hapi');

const todos = [];

const init = async () => {
    const server = Hapi.server({
        port: 3000,
        host: 'localhost'
    });

    server.route({
        method: 'GET',
        path: '/todos',
        handler: (request, h) => todos
    });

    server.route({
        method: 'POST',
        path: '/todos',
        handler: (request, h) => {
            const todo = request.payload;
            todos.push(todo);
            return h.response(todo).code(201);
        }
    });

    await server.start();
    console.log('Server running on %s', server.info.uri);
};

init();

Demonstrates a simple Hapi.js server with routes for listing and creating Todo items.
