I created a React app in order to build an electron app. I'm trying to use electron-builder to create the installers. I'm working on Ubuntu trying to generate a .deb.

I didn't use create-react-app, I used a boilerplate I already had, but I don't know if this is the problem.

I can make it work as long as I edit the index.html the webpack generates in the build folder. I have to change the path to main.css and build.js from /main.css and /build.js to ./main.css and ./build.js.

I read that I have to use the "homepage" property in package.json, but it's not working, seems to be ignored.

My folder structure is like:

package.json

src/

config/

main_electron_file.js

build/ #generated by webpack when I run the 'build:prd' command

public/ #empty

package.json

main_electron_file.js

// Modules to control application life and create native browser window

const { app, BrowserWindow } = require('electron');



const path = require('path');

const url = require('url');



// 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 mainWindow



function createWindow() {

  const startUrl = process.env.ELECTRON_START_URL || url.format({

    pathname: path.join(__dirname, 'build/index.html'),

    protocol: 'file:',

    slashes: true

  });



  // Create the browser window.

  mainWindow = new BrowserWindow({ width: 800, height: 600, resizeble: false });

  mainWindow.setResizable(false);



  // and load the index.html of the app.

  // win.loadURL('http://localhost:3000');

  mainWindow.loadURL(startUrl);



  // Open the DevTools.

  mainWindow.webContents.openDevTools()



  // Emitted when the window is closed.

  mainWindow.on('closed', function () {

    // 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.

    mainWindow = 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', function () {

  // On OS X 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.quit()

  }

})



app.on('activate', function () {

  // On OS X 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 (mainWindow === null) {

    createWindow()

  }

})



// 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.

By the way. I'm not building it. I'm running it pointing to the index.html in the dist, as I would do in production mode. So i'm running npm run build:prd and then npm run electron

ANy ideas how I could make this process automatic?

Please try adding this line in your index.html

<base href="./">

And your main.css and build.js directory should be set relative to your index.html in build folder
