node concurrently模块同时运行多个命令

冷不防 2022-10-23 08:14 287阅读 0赞

同时运行多个命令。比如：

npm run watch-js & npm run watch-less

但比这种方式要更好一些。

它也适用于Windows。你可以调整npm脚本达到跨平台运行的效果。

### 安装 ###

这个工具是使用nodejs写的，但是可以用来运行任何命令

你可以选择全局安装

npm install -g concurrently

也可以局部安装

npm install concurrently --save-dev

### 用法 ###

请记住用引号将每个单独的命令括起来，如下所示：

concurrent "command1 arg" "command2 arg"

否则，concurrent将尝试运行4个单独的命令：

command1, arg, command2, arg

在双引号内需要转义

"concurrently \"npm run dev:preload\" \"npm run dev:electron\""

### 示例 ###

Help

Usage: concurrent [options] <command ...>
    
      Options:
    
        -h, --help                    output usage information
        -V, --version                 output the version number
        -k, --kill-others             kill other processes if one exits or dies
        --no-color                    disable colors from logging
        -p, --prefix <prefix>         prefix used in logging for each process.
        Possible values: index, pid, command, none. Default: index
    
        -r, --raw                     output only raw output of processes, disables prettifying and colors
        -l, --prefix-length <length>  limit how many characters of the command is displayed in prefix.
        The option can be used to shorten long commands.
        Works only if prefix is set to "command". Default: 10
    
    
      Examples:
    
       - Kill other processes if one exits or dies
    
           $ concurrent --kill-others "grunt watch" "http-server"
    
       - Output nothing more than stdout+stderr of child processes
    
           $ concurrent --raw "npm run watch-less" "npm run watch-js"
    
       - Normal output but without colors e.g. when logging to file
    
           $ concurrent --no-color "grunt watch" "http-server" > log
