custom build - build multiple projects with only one node_modules

[QuinsZouls]

I have multiple proyects of polymer, but each one has its own modules to be compiled

but what I need is to share the same node_modules for all the projects I have, since they all use the same modules

Using custom build tools for build pwa

const fs = require('fs-extra');
const polymerBuild = require('polymer-build');
const path = require('path');
const build = require('./build/build').build; // custom polymer builder
const utils = require('./util');

/**
 * @param {String} name 
 */
async function buildProyect(name) {
  var setting = require(path.join(
    __dirname,
    '..',
    'proyects',
    name,
    'polymer.json'
  ));
  setting.root = path.join(__dirname, '..', 'proyects', name); //configure path root of the proyect

  const project = new polymerBuild.PolymerProject(setting);
  const buildSettings = utils.getBuildSettings(name);
  let arr = [];
  for (setting of buildSettings) {
    arr.push(build(setting, project, name));
  }
  await Promise.all(arr);
}

if there are no node_modules in the project root, it does not compile the pwa

My idea is to put the node_modules in the project folder, but when doing this the constructor always looks in the root of the project, now my question is: How do I take the node_modules of the project directory to build the pwa?

for that I tried to put the absolute path where the modules were in the file polymer.json, but it did not work

What about using symlinks?

[QuinsZouls]

i am used build script but apparently the script does not take up symlinks

[QuinsZouls]

This is my implementation but I'm not sure if it's adequate

const symlinkDir = require('symlink-dir');
const path = require('path');

const modules = path.join(__dirname, '..', 'proyects', 'node_modules');

/**
 *
 * @param {String} utl path of node_modules 
 */
function createNodeLink(utl) {
  return symlinkDir(modules, utl)
    .then(result => {
      console.log(result);
      return symlinkDir(modules, utl);
    })
    .then(result => {
      console.log(result);
    })
    .catch(err => console.error(err));
}
module.exports = {
  createNodeLink
}
