How to use electron on Jhipster Angular generated application?

I just discovered electron and I found it interesting, so I wan't to implement it on my jhipster angular project (lastest jhipster version)

I tried following this tutorial and adapt it but I believe since Jhipster uses Webpack my build is not fine

here is what I have done

I declared a main.js file in src/main/webapp folder as below

const { app, BrowserWindow } = require("electron");
const path = require("path");
const url = require("url");

let win;

function createWindow() {
  win = new BrowserWindow({ width: 800, height: 600 });

  // load the dist folder from Angular
  win.loadURL(
    url.format({
      pathname: path.join(__dirname, `/dist/index.html`),
      protocol: "file:",
      slashes: true
    })
  );

  // The following is optional and will open the DevTools:
  // win.webContents.openDevTools()

  win.on("closed", () => {
    win = null;
  });
}

app.on("ready", createWindow);

// on macOS, closing the window doesn't quit the app
app.on("window-all-closed", () => {
  if (process.platform !== "darwin") {
    app.quit();
  }
});

// initialize the app's main window
app.on("activate", () => {
  if (win === null) {
    createWindow();
  }
});

Then I tried updating my config files as below

package.json

{
  "name": "boxing",
  "version": "0.0.1-SNAPSHOT",
  "main": "main.js", <-- added this
  "description": "Description for boxing",
  "private": true,
  "license": "UNLICENSED",
  "cacheDirectories": [
    "node_modules"
  ],
  "dependencies": {
    "@angular-devkit/build-angular": "^0.803.14", <-- installed using npm
    ...
  "scripts": {
    "electron": "ng build --base-href ./ && electron .",

angular.json

{
  "$schema": "./node_modules/@angular/cli/lib/config/schema.json",
  "version": 1,
  "newProjectRoot": "projects",
  "projects": {
    "boxing": {
      "root": "",
      "sourceRoot": "src/main/webapp",
      "projectType": "application",
      "schematics": {
        "@schematics/angular:component": {
          "skipTests": true,
          "style": "scss"
        },
        "@schematics/angular:directive": {
          "skipTests": true
        },
        "@schematics/angular:guard": {
          "skipTests": true
        },
        "@schematics/angular:pipe": {
          "skipTests": true
        },
        "@schematics/angular:service": {
          "skipTests": true
        }
      },
      "prefix": "jhi",
      "architect": {
        <-- added this lines
        "build": {
          "builder": "@angular-devkit/build-angular:browser",
          "options": {
            "outputPath": "dist"
          }
        }
       <-- end of add
      }
    }
  },
  "defaultProject": "boxing",
  "cli": {
    "packageManager": "npm"
  }
}

I updated finally my index.html href to ./

but when I run the command in terminal I m getting this error

npm run electron

boxing@0.0.1-SNAPSHOT electron /home/housseyn/Desktop/projects/salle-de-sport ng build --base-href ./ && electron .
