思路

创建loading页
创建loading进程
主进程之前加载loading进程
loading进程隐藏销毁，然后进入主进程

思路+AI=轻松解决

1. 在index.html同级创建一个loading.html

样式是找AI要的，假的进度条，按照大概的加载时间给duration ，最后的加载完成需要从主进程中给消息，然后直接到100%。

<!doctype html>
<html lang="zh-CN"><head><meta charset="UTF-8" /><meta name="viewport" content="width=device-width, initial-scale=1.0" /><title>xxx软件启动页</title><style>body {margin: 0;padding: 0;display: flex;justify-content: center;align-items: center;height: 100vh;background-color: #f5f7fa;font-family: 'Arial', sans-serif;}.loader-container {width: 600px;height: 400px;background-color: white;border-radius: 12px;box-shadow: 0 10px 30px rgba(0, 0, 0, 0.1);display: flex;flex-direction: column;justify-content: center;align-items: center;padding: 40px;box-sizing: border-box;}.loader-title {font-size: 24px;color: #333;margin-bottom: 30px;font-weight: 500;}.progress-container {width: 80%;height: 8px;background-color: #e0e5ec;border-radius: 4px;margin-bottom: 30px;overflow: hidden;}.progress-bar {height: 100%;width: 0%;background: linear-gradient(90deg, #4facfe 0%, #00f2fe 100%);border-radius: 4px;transition: width 0.3s ease;}.percentage {font-size: 36px;font-weight: 300;color: #4facfe;margin-bottom: 20px;}.loading-text {font-size: 16px;color: #888;text-align: center;line-height: 1.5;}.spinner {width: 50px;height: 50px;border: 4px solid rgba(79, 172, 254, 0.2);border-top: 4px solid #4facfe;border-radius: 50%;animation: spin 1s linear infinite;margin-bottom: 30px;display: none;}@keyframes spin {0% {transform: rotate(0deg);}100% {transform: rotate(360deg);}}</style></head><body><div class="loader-container"><div class="spinner" id="spinner"></div><div class="loader-title">正在加载内容...</div><div class="percentage" id="percentage">0%</div><div class="progress-container"><div class="progress-bar" id="progressBar"></div></div><div class="loading-text" id="loadingText">初始化系统资源，请稍候...</div></div><script>const progressBar = document.getElementById('progressBar')const percentage = document.getElementById('percentage')const loadingText = document.getElementById('loadingText')const spinner = document.getElementById('spinner')// 显示旋转动画spinner.style.display = 'block'loadingText.textContent = '正在加载...'// 分阶段加载动画function animateProgress() {let progress = 0const targetProgress = 100const duration = 8000 // 总动画时长2秒const startTime = Date.now()function update() {const elapsed = Date.now() - startTimeprogress = Math.min((elapsed / duration) * 100, targetProgress)progressBar.style.width = `${progress}%`percentage.textContent = `${Math.floor(progress)}%`// 更新加载状态文本if (progress < 30) {loadingText.textContent = '初始化系统资源...'} else if (progress < 70) {loadingText.textContent = '加载核心模块...'} else {loadingText.textContent = '最终处理中...'}if (progress < targetProgress) {requestAnimationFrame(update)} else {loadingComplete()}}requestAnimationFrame(update)}animateProgress()function loadingComplete() {loadingText.textContent = '加载完成！即将进入系统...'spinner.style.display = 'none'// 添加完成动画progressBar.style.transition = 'all 0.5s ease'progressBar.style.width = '100%'percentage.textContent = '100%'}// 监听主进程消息window.api.onLoadingComplete(() => {// 当API完成时，立即完成剩余动画loadingComplete()})</script></body>
</html>

2. 创建一个同主进程一样的loading进程

需要preload往loading.html传递消息
在这里我需要loading的时候，调通一个接口才能进入主进程，所以用promise返回主进程窗口

function showLoading(cb: () => BrowserWindow): Promise<BrowserWindow> {return new Promise((resolve) => {let win: BrowserWindow | null = nullloadingWindow = new BrowserWindow({show: false,frame: false, // 无边框（窗口、工具栏等），只包含网页内容width: 600,height: 400,resizable: false,transparent: false,icon: join(__dirname, '../../resources/icon.png'), // Windows/LinuxwebPreferences: {preload: join(__dirname, '../preload/index.js'),sandbox: false}})/*** @description 接口调通才创建主进程*/loadingWindow.once('show', async () => {try {const response = await getHealth()if (response.data.code === 200) {// 启动页完成loadingWindow?.webContents.send('loading-complete')win = cb()resolve(win)}} catch (error: any) {loadingWindow?.destroy()}})if (!app.isPackaged && process.env['ELECTRON_RENDERER_URL']) {loadingWindow.loadURL(`${process.env['ELECTRON_RENDERER_URL']}/loading.html`)} else {loadingWindow.loadFile(join(__dirname, '../renderer/loading.html'))}loadingWindow.show()})
}

3. 创建一个消息通信

onLoadingComplete: (callback) => ipcRenderer.once('loading-complete', callback)

4. 在主进程启动之前调用loading进程进入加载页，然后销毁加载页进入主进程

loading进程里面返回主进程

  app.whenReady().then(async () => {//开发用showLoading(createWindow).then((res: BrowserWindow) => {mainWindow = res/*** @description 修改文件后 检查保存文件*/checkSaveFile(mainWindow)/*** @description 直接关闭窗口*/closeWindow(mainWindow)})})

先隐藏在销毁，然后展示主进程

  mainWindow.on('ready-to-show', () => {//隐藏启动页if (loadingWindow && !loadingWindow?.isDestroyed()) {loadingWindow?.hide()loadingWindow?.removeAllListeners()loadingWindow?.destroy()}mainWindow.show()})

实现效果

加载页

进入系统

在这里插入图片描述

注意打包时候需要把loading.html打包进去

这里我用的electron-vite

// electron.vite.config.ts
export default defineConfig({main: {},preload: {},renderer: {build: {rollupOptions: {input: {main: resolve(__dirname, 'src/renderer/index.html'),loading: resolve(__dirname, 'src/renderer/loading.html')}}},}
})
