javascript - Provide custom parameters ($npm_config_) to npm scripts on Windows - Stack Overflow

文章数量:1394139

I have npm scripts in the package.json, I would like to provide custom parameter from the mand line. I found many stackoverflow questions and answers but none of them works. I tried this solution:

  "scripts": {
    "foo": "echo $npm_config_foo && echo done"
  },

When I run the mand:

$ npm run foo --foo=test

> echo $npm_config_foo && echo done

$npm_config_foo
done

As you can see, it does not echo test.

This is my configuration:

- OS: Windows
- Terminal: GitBash
- npm version: 7.14.0

I tried this, on Linux and it works. This is related to Windows.

The accepted answer is Great but does not work if the Repo is used by both Windows and Linux Users. If so than I remend to use cross-var (https://www.npmjs./package/cross-var)

Just add it into the beginning of the script (after you added it to your dependencies)

"scripts": {
  "foo": "cross-var echo $npm_config_foo && echo done",
},

The solution is to use % instead of $.

  "scripts": {
     "foo": "echo %npm_config_foo% && echo done",
  },
