Mi código principal. Tengo "require('node-rsa')" que está en la carpeta node_modules. ¿Es posible crear un archivo a partir de este código?

a.js

 var testFunct = function test(message) { const NodeRSA = require('node-rsa'); const key = new NodeRSA(); var k = key.generateKeyPair(); var p = k.exportKey('pkcs1'); return p}; console.log(testFunct())

paquete.json

 { "name": "pol", "version": "1.0.0", "description": "", "main": "a.js", "dependencies": { "node-rsa": "^1.1.1", "build": "webpack a.js b.js" }, "devDependencies": { "webpack": "^5.58.2" }, "scripts": { "test": "echo \"Error: no test specified\" && exit 1" }, "author": "", "license": "ISC" }

webpack.config.js

 module.exports = { entry: ['a.js'], output: { path: './build', filename: 'bundle.js' } }
