Electron

1. 仅启动一个程序

if (!app.requestSingleInstanceLock()) {
  app.quit()
  return
}

app.on('second-instance', () => {
  if (!mainWindow) return
  if (mainWindow.isMinimized()) mainWindow.restore()
  mainWindow.focus()
  mainWindow.show()
})

2. 点击关闭最小化程序

mainWindow.on('close', e => {
  e.preventDefault()
  mainWindow.hide()
})

3. 开机自启

// 判断开机自启
app.getLoginItemSettings({ args: ['--openAsHidden'] }).openAtLogin

// 设置开机自启
app.setLoginItemSettings({
  openAtLogin,
  openAsHidden: true,
  args: ['--openAsHidden'],
})

// 如果不是开机自启，最大化显示程序
mainWindow = new BrowserWindow({
  show: false,
})

mainWindow.on('ready-to-show', () => {
  if (!process.argv.includes('--openAsHidden')) {
    mainWindow.maximize()
    mainWindow.show()
  }
})

4. 点击托盘

tray.on('click', () => {
  if (mainWindow.isVisible()) {
    if (mainWindow.isMinimized()) {
      mainWindow.restore()
      mainWindow.focus()
    } else {
      mainWindow.focus()
    }
  } else {
    mainWindow.maximize()
    mainWindow.show()
  }
})

5. 自动更新

import type { BrowserWindow } from 'electron'
import log from 'electron-log'
import { autoUpdater } from 'electron-updater'

const setupUpdate = (mainWindow: BrowserWindow) => {
  log.transports.file.level = 'info'
  autoUpdater.logger = log
  autoUpdater.checkForUpdatesAndNotify()

  autoUpdater.on('checking-for-update', () => {
    mainWindow.webContents.send('update:checking')
  })

  autoUpdater.on('update-available', () => {
    mainWindow.webContents.send('update:available', true)
  })

  autoUpdater.on('update-not-available', () => {
    mainWindow.webContents.send('update:available', false)
  })

  autoUpdater.on('error', error => {
    mainWindow.webContents.send('update:error', error)
  })

  autoUpdater.on('download-progress', ({ percent }) => {
    mainWindow.webContents.send('update:progress', percent)
  })

  autoUpdater.on('update-downloaded', () => {
    mainWindow.webContents.send('update:downloaded')
  })
}

export default setupUpdate
