Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

快速开始

安装

npm install leo-web-monitor

基础使用

import { LeoWebMonitor } from 'leo-web-monitor';

// 简单初始化
const monitor = new LeoWebMonitor({
  apiKey: 'your-api-key',
  endpoint: 'https://your-api-endpoint.com/errors',
  debug: true
});

// 启动监控
monitor.start();

// 手动捕获错误
monitor.captureError('Something went wrong', {
  userId: '12345',
  page: 'home'
});

HTML直接引入

<script src="./dist/index.umd.js"></script>
<script>
  const monitor = new LeoWebMonitor.default({
    debug: true,
    autoCapture: true
  });
  monitor.start();
</script>

配置选项

const monitor = new LeoWebMonitor({
  // 必选配置
  apiKey: 'your-api-key',              // API密钥
  endpoint: 'https://api.example.com', // 上报端点
  
  // 可选配置
  timeout: 5000,                       // 请求超时时间(ms)
  retryTimes: 3,                       // 重试次数
  debug: false,                        // 调试模式
  autoCapture: true,                   // 自动捕获错误
  maxErrorQueueSize: 100,              // 错误队列最大长度
  reportInterval: 2000,                // 上报间隔(ms)
  
  // 自定义过滤器
  errorFilter: (error) => {
    // 返回true表示需要上报,false表示忽略
    return !error.message.includes('Script error');
  },
  
  // 错误回调
  onError: (error) => {
    console.log('捕获到错误:', error);
  }
});

API文档

主要方法

start()

启动错误监控

monitor.start();

stop()

停止错误监控

monitor.stop();

captureError(error, extra?)

手动捕获错误

monitor.captureError('Error message', {
  userId: '123',
  action: 'click_button'
});

monitor.captureError(new Error('Something wrong'), {
  component: 'UserProfile'
});

captureMessage(message, extra?)

捕获消息(等同于captureError)

monitor.captureMessage('User action completed', {
  action: 'form_submit',
  formId: 'contact-form'
});

getErrorStats()

获取错误统计信息

const stats = monitor.getErrorStats();
console.log(stats);
// {
//   totalErrors: 10,
//   pendingReports: 3,
//   queueSize: 7
// }

getErrors()

获取所有收集的错误

const errors = monitor.getErrors();
console.log(errors);

clearErrors()

清空错误队列

monitor.clearErrors();

updateConfig(newConfig)

更新配置

monitor.updateConfig({
  debug: true,
  timeout: 10000
});

错误类型

SDK支持以下错误类型:

  • JAVASCRIPT_ERROR: JavaScript运行时错误
  • PROMISE_ERROR: 未处理的Promise拒绝
  • RESOURCE_ERROR: 资源加载错误
  • NETWORK_ERROR: 网络请求错误
  • CUSTOM_ERROR: 手动捕获的自定义错误

错误信息结构

interface ErrorInfo {
  message: string;      // 错误消息
  stack?: string;       // 错误堆栈
  type: ErrorType;      // 错误类型
  timestamp: number;    // 发生时间
  url: string;          // 页面URL
  userAgent: string;    // 用户代理
  filename?: string;    // 错误源文件
  lineno?: number;      // 错误行号
  colno?: number;       // 错误列号
  extra?: Record<string, any>; // 额外信息
}

高级用法

与React集成

import { LeoWebMonitor } from 'leo-web-monitor';

const monitor = new LeoWebMonitor({
  apiKey: 'your-api-key',
  endpoint: 'https://api.example.com/errors'
});

// 错误边界
class ErrorBoundary extends React.Component {
  componentDidCatch(error, errorInfo) {
    monitor.captureError(error, {
      componentStack: errorInfo.componentStack,
      errorBoundary: true
    });
  }
  
  render() {
    if (this.state.hasError) {
      return <h1>Something went wrong.</h1>;
    }
    return this.props.children;
  }
}

与Vue集成

import { LeoWebMonitor } from 'leo-web-monitor';

const monitor = new LeoWebMonitor({
  apiKey: 'your-api-key',
  endpoint: 'https://api.example.com/errors'
});

const app = createApp({});
app.config.errorHandler = (err, vm, info) => {
  monitor.captureError(err, {
    vueErrorInfo: info,
    componentName: vm?.$options.name || 'Unknown'
  });
};

网络请求监控

async function monitoredFetch(url, options = {}) {
  try {
    const response = await fetch(url, options);
    if (!response.ok) {
      monitor.captureError(`HTTP ${response.status}: ${response.statusText}`, {
        type: 'network_error',
        url,
        status: response.status
      });
    }
    return response;
  } catch (error) {
    monitor.captureError(error, {
      type: 'network_error',
      url
    });
    throw error;
  }
}
