electron-packager packages the web page into a desktop application setting icon does not work, replace the electron-packager default icon

The problem that the icon cannot be changed may be caused by the following reasons:

1. Confirm the image format and size:

Electron needs to use the .ico format as the icon file on the windows platform instead of the .png or .svg format, so you should convert the icon file to the .ico format. Also, make sure the image size is no larger than 256x256 pixels.

2. Confirm that the file path is correct:

Make sure you set the --icon parameter in the application packaging command and specify the correct path to the .ico file, for example:

electron-packager . MyApp --icon=path/to/icon.ico

Pro test is effective

In the command example above, the path to the icon points to the icon.ico file in the root directory of the project.

3. Clear the cache and reinstall the app:

In some cases, the application's cache may cause the original icon to be wrongly cached and not take effect. Uninstalling and clearing the cache and reinstalling the application may help.

4. Set directly on the BrowserWindow instance:

Set the window icon through the BrowserWindow instance as follows:

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

function createWindow () {
    
    
  const win = new BrowserWindow({
    
    
    width: 800,
    height: 600,
    icon: __dirname + '/myicon.ico' // 图标的路径
  })

  win.loadFile('index.html')
}

app.whenReady().then(() => {
    
    
  createWindow()
})

In the code above, you can specify the application's .ico icon file by setting the icon property in the window options object.
