Opinionated startup for node applications. Get rid of boilerplate.
Alfalfa comes from Alpha. Because this will become the very beginning of every Node.js service you create
import alfalfa from 'alfalfa';
import express from 'express';
import http from 'http';
const app = express();
let app = express(); // use your favorite framework
let server = http.createServer(app); // your app will be exposed as an http server
let agent = new http.Agent({ keepAlive: true });
// Create a startup way to bring up your service
let startup = alfalfa.Startup();
// Check some preconditions before starting
// Configure the runners you want to use
startup.use(alfalfa.AgentRunner({ agent }));
startup.use(alfalfa.ServerRunner({ server, port: 3000 }));
startup.bootstap('Service'); // Yeah! Create the process with title 'Service'What's is going on here? Alfalfa bootstraps your app by starting each one of the runners defined. Each runner is a proven block that saves you from writing boilerplate and error-prone code again and again. There are several runners available. More on this can be found in the example folder.
Moreover, alfafa also prints traces for monitoring the startup, and manages the operating system signals and unhandled exceptions/rejections/warnings.
