electron 启动加载动画效果

前言

对于项目加载动画效果启动的页面，就是那种loading界面

研究了下，然后还是这种最好

上代码吧

main.ts 文件下

const createWindow = () => {
  return new Promise((resolve, reject) => {
  // Create the browser window.
  const mainWindow = new BrowserWindow({
    width: 800,
    height: 600,
    webPreferences: {
      preload: path.join(__dirname, 'preload.js'),
    },
    title: '主传开',
    show: false,
    backgroundColor: 'pink'
  });

  const view = new BrowserView()
  mainWindow.setBrowserView(view)
  view.setBounds({x: 0, y: 0,width: 800, height: 600})
  view.webContents.loadFile('loading.html')
  view.webContents.on('dom-ready', ()=>{
    console.log('加载完成')
    mainWindow.show()
  })
  mainWindow.once('ready-to-show', ()=>{
        setTimeout(() => {
          console.log('完成')
          mainWindow.removeBrowserView(view)
    }, 500);  

  })
  ipcMain.on('stop-loading-main', ()=>{
    mainWindow.removeBrowserView(view)
  })

  // and load the index.html of the app.
  if (MAIN_WINDOW_VITE_DEV_SERVER_URL) {
    mainWindow.loadURL(MAIN_WINDOW_VITE_DEV_SERVER_URL);
  } else {
    mainWindow.loadFile(path.join(__dirname, `../renderer/${MAIN_WINDOW_VITE_NAME}/index.html`));
  }



  // Open the DevTools.
  mainWindow.webContents.openDevTools();
}); 
};

</html>

preload.ts


window.stopLoading = function() {
    ipcRenderer.send('stop-loading-main')
}

renderer.ts

setTimeout(() => {
    window.stopLoading()
}, 1000)

ok 这样就完成了
