Why is my Angular 8 app not properly packaging my app using Electron Packager?

I have been trying to export my Angular 8 app to a desktop app using Electron. I figured out how to run it with Electron, but when I decide to use the electron packager I run into an error. The error I get has to do with the ‘app-root-path’ not being found. I am using a main.ts and turning it into the main.js Electron uses. Any help would be appreciated.


import { app, BrowserWindow } from 'electron';
import { resolve } from 'app-root-path';
// Keep a global reference of the window object, if you don't, the window will
// be closed automatically when the JavaScript object is garbage collected.
let win: BrowserWindow;
function createWindow () {
  // Create the browser window.
  win = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      nodeIntegration: true,
  // Load the angular app.
  // Make sure that this path targets the index.html of the
  // angular application (the distribution).
  // Emitted when the window is closed.
  win.on('closed', () => {
    // Dereference the window object, usually you would store windows
    // in an array if your app supports multi windows, this is the time
    // when you should delete the corresponding element.
    win = null;
// This method will be called when Electron has finished
// initialization and is ready to create browser windows.
// Some APIs can only be used after this event occurs.
app.on('ready', createWindow);
// Quit when all windows are closed.
app.on('window-all-closed', () => {
  // On macOS it is common for applications and their menu bar
  // to stay active until the user quits explicitly with Cmd + Q
  if (process.platform !== 'darwin') {
app.on('activate', () => {
  // On macOS it's common to re-create a window in the app when the
  // dock icon is clicked and there are no other windows open.
  if (win === null) {
// In this file you can include the rest of your app's specific main process
// code. You can also put them in separate files and require them here.

Whenever I compile the app and Electron-packager creates the exe I click it but I get the same error. “Javascript error: Error: Cannot find module ‘app-root-path’ require stack: /Invoices/Invoices electron app-darwin-x64/Invoices electron” The only other issue I had had was having to set the tsconfig.json target to “es5” and then I ran into this issue when trying to use Electron-packager.


What got this working for me was to first set the start electron command to this

 "start:electron": "ng build --base-href ./ && electron ."

then in my angular.json set OutputPath to

 "outputPath": "dist"

Then to fix my final error of “Failed to load module script:” I changed in my tsconfig.json

"target": "es2015" to "target": "es5"

this fixed my application and allowed electron to work properly
