Getting Started
复制一个包含安装步骤和本插件的完整 Markdown 指南的配置提示。
Set up this Capacitor plugin in the project.
Use the package manager already used by the project.
Install these package(s): `@capgo/capacitor-webview-crash`
Run the required Capacitor sync/update step after installation.
Read this markdown guide for the full setup steps: https://raw.githubusercontent.com/Cap-go/website/refs/heads/main/apps/docs/src/content/docs/docs/plugins/webview-crash/getting-started.mdx
Use that guide for platform-specific steps, native file edits, permissions, config changes, imports, and usage setup.
If that guide references other docs pages, read them too.
npm install @capgo/capacitor-webview-crashnpx cap syncimport { WebViewCrash } from '@capgo/capacitor-webview-crash';推荐恢复流程
推荐恢复流程尽早在应用启动时附加监听器,以便恢复的运行时可以在用户继续浏览之前做出反应:
import { WebViewCrash } from '@capgo/capacitor-webview-crash';
await WebViewCrash.addListener('webViewRestoredAfterCrash', async (info) => { console.log('Recovered after a WebView crash', info);
// Rehydrate critical state, reopen the correct screen, or prompt the user to retry. await WebViewCrash.clearPendingCrashInfo();});
await WebViewCrash.addListener('webViewRestoredAfterRestart', async (info) => { console.log('Recovered after a native WebView restart', info); await WebViewCrash.clearPendingCrashInfo();});
const pending = await WebViewCrash.getPendingCrashInfo();// Note: the listener callback may have already cleared the pending marker.if (pending.value) { console.log('Pending crash or restart marker', pending.value);}原生自动重启
原生自动重启在 capacitor.config.ts 以便决策在JavaScript运行时崩溃或尚未加载时仍然在原生code中:
import type { CapacitorConfig } from '@capacitor/cli';import type { WebViewCrashPluginConfig } from '@capgo/capacitor-webview-crash';
const webViewCrash: WebViewCrashPluginConfig = { // Enabled by default. Keep this on for long-running apps. restartOnCrash: true,
// Use a 5-field cron schedule in the device local timezone. // Do not combine restartCron with an active restartIntervalMs. restartCron: '0 3 * * *',
// Optional delay before restarting after a crash. restartAfterCrashDelayMs: 0,};
const config: CapacitorConfig = { plugins: { WebViewCrash: webViewCrash, },};
export default config;用于 restartIntervalMs 始终开机的应用,用户可能会在几天内保持相同的WebView打开: restartCron 用于墙钟重启,如kiosk屏幕、控制室仪表盘、仓库扫描器、POS终端、车队平板电脑和数字显示屏。 0 3 * * * 在设备本地时区的每日 03:00 重启。预定重启写入一个等待标记与 reason: 'periodicRestart'然后 Android 重建了宿主活动,iOS 重建了Capacitor 桥视图,因此创建了一个新的 WKWebView 从本机code 创建。
选择一个间隔或 cron 计划,产品可以容忍的时间。 restartCron 支持 *, 列表,范围和步骤。不要同时配置两个计划:本机初始化会在 restartCron 设置且 restartIntervalMs 大于 0时抛出致命配置错误。重启会创建一个新的 JavaScript 运行时,因此在使用激进计划前,请保存排队事件、未保存的表单状态和当前导航状态。
手动本机重启
手动本机重启手动本机重启 restartWebView() 当当前 JavaScript 运行时决定原生 WebView 应该被替换时,例如在内存密集型工作流程之后或进入长时间无人监控的会话之前:
await WebViewCrash.restartWebView();该方法写入一个待处理的标记符号, reason: 'manualRestart'解决当前的调用,然后要求原生 code 创建一个新的 WebView。Android 重建宿主活动。iOS 重建 Capacitor 桥视图,因此创建了一个新的 WKWebView 而不是重新加载当前页面。
API 概述
标题:“API 概述”getPendingCrashInfo
标题:“getPendingCrashInfo”返回存储的原生崩溃或重启标记,或者 null 当没有待处理的标记时。
const pending = await WebViewCrash.getPendingCrashInfo();if (pending.value) { console.log(pending.value.platform, pending.value.reason);}clearPendingCrashInfo
标题:“clearPendingCrashInfo”在恢复处理完成后,清除存储的标记。
await WebViewCrash.clearPendingCrashInfo();simulateCrashRecovery
模拟崩溃恢复部分为 QA 和本地调试创建一个假的崩溃标记,以便可以在不崩溃真实 WebView 的情况下演练恢复路径。
const simulated = await WebViewCrash.simulateCrashRecovery();console.log(simulated.value);restartWebView
重启 WebView 部分存储一个手动重启标记,并要求本地 code 创建一个新的 WebView。
await WebViewCrash.restartWebView();平台说明
模拟崩溃恢复部分- Android 从
onRenderProcessGone,包括didCrash和rendererPriorityAtExit当平台提供时。 - iOS 从
webViewWebContentProcessDidTerminate并在可用时添加当前应用程序状态。 - 手动和计划重启创建一个新的 WebView。 Android 重建宿主活动; iOS 重建Capacitor 桥视图。
- 计划重启使用
reason: 'periodicRestart'; 手动重启使用reason: 'manualRestart'. - Web 不检测真实渲染器崩溃。 Web 实现仅使用本地存储模拟行为。
