Windows 上的 Node.Js - 如何清除控制台 [英] Node.Js on windows - How to clear console

问题描述

对 node.js 环境和哲学是全新的，我想回答几个问题.我已经下载了用于 windows 安装程序的 node.js 以及 node 包管理器.Windows Cmd 提示符当前正在用于运行 nodejs 应用程序.

Being totally new into node.js environment and philosophy i would like answers to few questions. I had downloaded the node.js for windows installer and also node package manager.Windows Cmd prompt is being currently used for running nodejs apps.

1. cls 清除命令窗口或命令提示符中的错误.node.js 是否有等价物?console.clear 不存在 ;( 还是以其他形式存在?

1. cls clears the command window or errors in command prompt. Is there a equivalent for node.js ? console.clear does not exist ;( or does it in some other form?

我通过下面这段代码创建了一个服务器

I created a server through this code below

var http = require("http");
http.createServer(function (request, response) {
    response.writeHead(200, {
        "Content-Type": "text/html"
    });
    response.write("Hello World");
    console.log("welcome world")response.end();
}).listen(9000, "127.0.0.1");

我将代码更改为下面并刷新浏览器发现内容类型没有改变，我如何才能看到变化?

i changed the code to below and refreshed the browser to find that content type does not change, how do i get to see the changes?

var http = require("http");
http.createServer(function(request, response) {
  response.writeHead(200, {"Content-Type": "text/plain"});
  response.write("Hello World");
  console.log("welcome world")
  response.end();
}).listen(9000,"127.0.0.1");

推荐答案

console.log('33[2J');

这适用于 linux.不确定 Windows.

This works on linux. Not sure about windows.

您可以使用以下方式欺骗"用户:

You can "trick" the user using something like this:

var lines = process.stdout.getWindowSize()[1];
for(var i = 0; i < lines; i++) {
    console.log('
');
}
