安装

npm install @capgo/capacitor-webview-crash
npx cap sync

导入

import { WebViewCrash } from '@capgo/capacitor-webview-crash';

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

在 capacitor.config.ts 这样即使JavaScript运行时已崩溃或未加载，原生code仍然保持不变：

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;

使用 restartIntervalMs 始终开启的应用程序，用户可能会在几天内保持相同的WebView打开： restartCron 使用 0 3 * * * 墙时钟重启，如 reason: 'periodicRestart', then Android recreates the host activity and iOS rebuilds the Capacitor bridge view so a new WKWebView is created from native code.

选择一个产品可以容忍的时间间隔或cron调度。 restartCron 支持 *, 列表、范围和步长。请勿同时配置两个调度：当 restartCron 设置为true且 restartIntervalMs 大于 0时，native初始化会抛出致命配置错误。重启会创建一个新的JavaScript运行时，因此在使用激进调度之前，请务必保存排队事件、未保存的表单状态和当前导航状态。

手动native重启

调用 restartWebView() 当当前JavaScript运行时决定native WebView应该被替换时，例如在内存密集型工作流或进入长时间未attended会话之前：

await WebViewCrash.restartWebView();

该方法写入一个待处理标记 reason: 'manualRestart'解决当前调用后，native code 会创建一个新的 WebView。Android 会重新创建宿主活动。iOS 会重建 Capacitor 桥视图以创建一个新的 WKWebView 而不是重新加载当前页面。

API 概述

getPendingCrashInfo

返回存储的native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

清除存储的标记后，完成恢复处理。

await WebViewCrash.clearPendingCrashInfo();

simulateCrashRecovery

创建一个虚拟的崩溃标记，以便 QA 和本地调试可以在不崩溃真实 WebView 的情况下演练恢复路径。

const simulated = await WebViewCrash.simulateCrashRecovery();
console.log(simulated.value);

restartWebView

存储一个手动重新启动标记并要求本地 code 创建一个新的 WebView。

await WebViewCrash.restartWebView();

平台说明

• Android 将崩溃元数据存储在 onRenderProcessGone包括 didCrash 和 rendererPriorityAtExit 当平台提供它们时。
• iOS 将崩溃元数据存储在 webViewWebContentProcessDidTerminate and adds the current application state when available.
• 手动和预定重启创建一个新的 WebView。Android 重建宿主活动；iOS 重建Capacitor 桥视图.
• 预定重启使用 reason: 'periodicRestart'；手动重启使用 reason: 'manualRestart'.
• Web 不检测真实的渲染器崩溃。Web 实现仅模拟本地存储的行为.
