Rollup + Lerna build and publish minify packages

[inner fable]

Hey there! I'm new at monorepo's topic but trying to get better on it.
I have had configured some files bellow and get this result:
Creating packages minified on dist root path of project.
But having the "problems" in sequence:
Duplicating node_modules
Not creating again package.json file for individual package (So I can't list all packages with lerna)
import path modified after build

//lerna.json
{
  "packages": [
    "packages/**"
  ],
  "version": "independent",
  "npmClient": "npm",
  "useWorkspaces":true
}

//buildUtils.js
const fs = require('fs');

export const getFiles = (entry, extensions = [], excludeExtensions = []) => {
  let fileNames = [];
  const dirs = fs.readdirSync(entry);

  dirs.forEach((dir) => {
    const path = `${entry}/${dir}`;

    if (fs.lstatSync(path).isDirectory()) {
      fileNames = [
        ...fileNames,
        ...getFiles(path, extensions, excludeExtensions),
      ];

      return;
    }

    if (!excludeExtensions.some((exclude) => dir.endsWith(exclude))
      && extensions.some((ext) => dir.endsWith(ext))
    ) {
      fileNames.push(path);
    }
  });

  return fileNames;
}
