How to make arguments in WebPack work?

Question

JavaScript

Hello
, I have the following commands in packaje.json

"test": "echo \"Error: no test specified\" && exit 1",
    "start": "npx webpack --config ./configs/webpack.config.js --watch",
    "server": "node echo_server.js",
    "dev": "concurrently --kill-others \"npm run server\" \"npm run start\""

And webpack.config.js looks like this:

const projectName = process.argv.splice(5)[0];

let file = `./${projectName}.config.js`;
const config = require(file);

module.exports = config;

The idea is this, I write the following on the command line:
npm run start orel
And it enters my config (orel.config.js) and executes the code specified
from
it in this version it looks like this:

Insufficient number of arguments or no entry found.
Alternatively, run 'webpack(-cli) --help' for usage info.


ERROR in Entry module not found: Error: Can't resolve 'orel' in 'C:\Users\Администратор\
Desktop\game\webpack-demo'

via "--"

Answer 2

Need to use environment variables
and run PROJECT=bestProject npm run start
And only then catch it in process.env.PROJECT
Or something like this in package
"start": "npx webpack --config ./configs/$PROJECT.config. js --watch",
