npm运行脚本的命名参数 [英] named parameter to npm run script

问题描述

我想将命名参数传递给npm运行脚本，以便执行以下操作:

I would like to pass a named parameter to an npm run script so I can do something like the following:

"scripts":{
    "say-hello":"echo $greeting && ls"
 }

 npm run hello --greeting=hello

我希望将'hello'代替$ greeting变量，回显命令，然后执行ls(这显然是链接命令的简单示例)

I'd like it to then put 'hello' in place of the $greeting variable, echo the command and then do the ls (this is obviously just a simple example of a chained command)

推荐答案

刚刚发现这可行:

"scripts":{
  "say-hello" : "echo $npm_config_greeting && ls"
}

任何以 npm_config _ 开头的环境变量都将被解释为配置参数.例如，将 npm_config_foo = bar 放入您的环境会将 foo 配置参数设置为 bar .

Any environment variables that start with npm_config_ will be interpreted as a configuration parameter. For example, putting npm_config_foo=bar in your environment will set the foo configuration parameter to bar.
