学习node.js/express.js:bin/www处理了什么? [英] Learning node.js/express.js: What's the deal with bin/www?

问题描述

我看过Express.js的教程，例如此，该教程从头开始有自己的app.js文件，并使用快速生成器放弃.

I've seen tutorials for express.js such as this which starts from scratch with their own app.js file and forgoes using the express generator.

我的问题:对于试图掌握如何使用这些工具并制作基本Web应用程序的初学者，我应该关注bin/www还是应该在app.js中定义端口?

My question: for beginner who's trying to grasp just how to use these tools and make a basic web application should I be concerned with bin/www or should I just be defining the port within app.js?

我目前在bin/www中唯一了解的功能是设置端口. Express生成器是否只是在边缘盒功能上肿了，而这对于初学者来说太多了?

The only functionality I currently understand in bin/www is setting the port. Is the express generator simply bloated with edge case functionality which is too much for a beginner?

推荐答案

这是原因，由快递维护人员简洁地指出:

Here is the reason, stated succinctly by an express maintainer:

因此，您可以从外部文件中请求('./app')并获得快递 不在任何端口上监听的应用程序(请考虑单元测试等).

So you can require('./app') from external files and get the express app that is not listening on any port (think unit tests and the like).
