Usage

Demos and examples are in this project: electron-multiple-window-demo

1. Install

npm i @canwdev/electron-window-manager
# Or yarn add @canwdev/electron-window-manager

2. Setup preload.js

Import our preload.js to electron-api.js

// src/utils/electron-api.js
const wmPreload = require('@canwdev/electron-window-manager/preload')

module.exports = {
  ...wmPreload,
  // Write your APIs here
}

Create your preload files and import electron-api.js:

• preload.js: for nodeIntegration: false and contextIsolation: true
• preload-node.js: for nodeIntegration: true

// src/preload.js
const {contextBridge} = require('electron')
const electronAPI = require('./utils/electron-api')
contextBridge.exposeInMainWorld(
  "electronAPI", electronAPI
);

// src/preload-node.js
const electronAPI = require('./utils/electron-api')
window.electronAPI = electronAPI
console.log('electronAPI loaded', electronAPI)

3. Setup main process

Create a global window manager instance run in main process

// src/utils/wm.js
const WindowManager = require('@canwdev/electron-window-manager')
const path = require('path')

const wm = new WindowManager({
  // setup preload path
  preloadDir: path.join(__dirname, '../')
})

module.exports = wm

Import in main process

// src/main.js
const wm = require('./utils/wm')

// Create a window
wm.createWindow({
    width: 800,
    height: 600,
    minWidth: 800,
    minHeight: 600,
    frame: false,
    webPreferences: {
      nodeIntegration: false,
      contextIsolation: true,
    },
    customConfig: {
      isOpenDevTools: isDev,
      saveWindowStateName: 'mainWindow',
    }
  },
  `http://localhost:3000`
