webpack supports export in the configuration file webpack.config.js , which accepts two parameters

  • env : environment
  • argv : parameter

all the parameters you pass in are in argv , so you can do this

. 
// webpack.config.js
module.exports = (env, argv) => {
    let abc=argv.abc
    return {
    // ...webpack config
    }
}

then start it like this 

webpack-dev-server --open  --abc=11111111

if you want to use it in your code, you can use DefinePlugin

. 
new webpack.DefinePlugin({
            ABC            : JSON.stringify(abc)
        })

in code 

if (ABC==='11111111'){
    alert(abc)
}
const json = require('../../package.json')
console.log(json.scripts)
