middleware
一个在 Express 路由层在最终请求处理程序之前被调用的函数，因此它位于原始请求和最终目标路由之间。关于中间件的一些细微术语：
🌐 A function that is invoked by the Express routing layer before the final request handler, and thus sits in the middle between a raw request and the final intended route. A few fine points of terminology around middleware:
var foo = require('middleware')被称为 require 或 使用 一个 Node.js 模块。然后语句var mw = foo()通常返回中间件。app.use(mw)被称为_将中间件添加到全局处理堆栈_。app.get('/foo', mw, (req, res) => { /* ... */ })被称为 将中间件添加到 “GET /foo” 处理栈。
Node.js
一个用于构建可扩展网络应用的软件平台。Node.js 使用 JavaScript 作为其脚本语言，并通过非阻塞 I/O 和单线程事件循环实现高吞吐量。参见 nodejs.org。使用说明：最初称为“Node.js”，之后称为“Node”。
🌐 A software platform that is used to build scalable network applications. Node.js uses JavaScript as its scripting language, and achieves high throughput via non-blocking I/O and a single-threaded event loop. See nodejs.org. Usage note: Initially, “Node.js,” thereafter “Node”.
开源
🌐 open-source, open source
当用作形容词时，需要用连字符；例如：“这是开源软件。” 参见 维基百科上的开源软件。
