Passing multiple named arguments to package.json script

I have a webpack config with currently three parameters, which works when I invoke it in the following way:

webpack --env.p1 = "p1_value" --env.p2 = "p2_value" --env.p3 = "p3_value"

Now I want to encapsulate that webpack command in the following package.json script: 

"scripts": {

        "prod": "webpack --env.p1 --env.p2 --env.p3"
    }

How do I have to change that script such that I can invoke it from the CLI in the following way

npm run prod p1="p1_value" p2="p2_value" p3="p3_value"

(where the named parameters are indispensible, because I need to be able to work with default values inside the webpack config?)

You can pass any arguments provided to the npm command through to webpack using the placeholder ${@:1}.

package.json

"scripts": {
  "prod": "webpack ${@:1}"
}

From the command line, add parameters to be passed through using -- as separator, like so:

npm run prod -- --env.p1="p1_value" --env.p2="p2_value" --env.p3="p3_value"
