如何制作一个npm命令，在控制台中执行两个命令（一个接一个）？ [英] How to make a npm command, that executes two commands in the console (one after another)?

问题描述

如何在package.json文件中创建一个命令，该命令一个接一个地为终端（控制台）执行两个命令？

How can I make a command in the package.json file, that executes two commands for the terminal (console) one after another?

此问题涉及 node.js 和 NPM包。

我有server文件夹，其中我安装了 http服务器和 npm package.json文件，还有一个文件夹webdir（在server文件夹中）带有网页。

I have a "server" folder in which I installed http server and npm package.json file, and there is also a folder "webdir" (inside "server" folder) with a web page.

我可以手动运行Web服务器，也可以输入terminal： node [运行服务器的文件的路径] ，但我需要在命令 npm start 。并且必须从webdir文件夹激活服务器，以便我可以立即转到我的网页 localhost：8080 。

I can run the web server manually, or by typing in the terminal: node [path to the file that runs the server], but I need this to happen automatically on command npm start. And the server must be activated from the "webdir" folder, so that I could immediately go to my web page at localhost: 8080.

为此，我需要一个接一个地在终端（控制台）中写两个命令：

To do this, I need to write in the terminal (console) two commands one after another:

1. cd webdir


2. node [运行Web服务器的文件的路径]

1. cd webdir
2. node [path to the file that runs the Web server]

以下是包含单行脚本的工作代码：

Here is the working code with a single line script:

"scripts": {
    "start": "node (...)/node_modules/http-server/bin/http-server"
  },

推荐答案

我所知道的语法涉及到使用&& 分隔命令，即

The syntax I'm aware of involves using && to separate the commands, i.e.

"cd webdir && node ..."

d在Windows和基于Unix的系统上都可以工作。

This should work both on Windows and on Unix based systems.

例如，jQuery在其部署脚本中使用这样的组合语句：

For example, jQuery uses such combined statements in its deploy scripts:

"build": "npm install && grunt",
"start": "grunt watch",
"test": "grunt && grunt test:slow",
"precommit": "grunt lint:newer",
"commitmsg": "node node_modules/commitplease"
