App is running in offline mode.) }, error (error) { console.error(Error during service worker registration:, error) } })3️⃣ 配置Service Worker文件确保项目根目录存在service-worker.js文件基础模板可参考// service-worker.js self.addEventListener(install, event { event.waitUntil( caches.open(app-cache-v1).then(cache { return cache.addAll([ /, /index.html, /styles.css, /app.js ]) }) ) }) self.addEventListener(fetch, event { event.respondWith( caches.match(event.request).then(response { return response || fetch(event.request) }) ) })核心事件钩子详解register-service-worker提供了丰富的事件钩子让你轻松控制Service Worker生命周期 ready当Service Worker激活并开始控制页面时触发ready (registration) { console.log(ServiceWorker控制范围:, registration.scope) }⬆️ updated检测到新版本Service Worker并完成安装时触发常用于提示用户刷新updated (registration) { if (confirm(发现新内容是否立即刷新)) { registration.waiting.postMessage({ type: SKIP_WAITING }) } } offline当用户离线时触发可用于显示离线状态提示offline () { document.getElementById(offline-banner).style.display block }高级配置选项自定义注册范围通过registrationOptions设置Service Worker控制范围register(/sw.js, { registrationOptions: { scope: /app/ }, // 其他钩子... })开发环境特殊处理工具会自动检测localhost环境提供额外的Service Worker有效性检查验证Service Worker文件是否存在检查文件MIME类型是否正确自动处理开发环境下的注册错误常见问题解决❓ Service Worker注册失败确保在HTTPS环境或localhost下测试检查Service Worker文件路径是否正确清除浏览器缓存后重试❓ 新内容不生效这是Service Worker的正常行为可通过以下方式解决updated (registration) { registration.waiting.addEventListener(statechange, event { if (event.target.state activated) { window.location.reload() } }) registration.waiting.postMessage({ type: SKIP_WAITING }) }项目源码结构核心逻辑src/index.js类型定义index.d.ts构建脚本scripts/build.js总结register-service-worker通过简洁的API设计让复杂的Service Worker注册过程变得轻松简单。只需5分钟你就能为Web应用添加离线访问能力显著提升用户体验。无论是个人项目还是企业级应用这款工具都能帮助你快速实现PWA特性是现代Web开发的得力助手。要开始使用只需执行git clone https://gitcode.com/gh_mirrors/re/register-service-worker探索更多示例和高级用法【免费下载链接】register-service-workerA script to simplify service worker registration with hooks for common events.项目地址: https://gitcode.com/gh_mirrors/re/register-service-worker创作声明：本文部分内容由AI辅助生成（AIGC），仅供参考
