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 🙏

前端监控 SDK

前端监控 SDK,用于错误监控、性能监控和用户行为追踪。

功能特点

  • 错误监控:捕获 JS 异常、Promise 错误、资源加载错误、HTTP 请求错误等
  • 性能监控:记录页面加载性能、资源加载时间、Web Vitals 核心指标等
  • 用户行为追踪:PV/UV 统计、点击事件追踪、路由变化记录等
  • 调试能力:支持通过 CDN 引入 eruda 调试面板,可通过特定触发方式打开
  • 控制台管理:封装原生 console,支持开启/关闭日志输出
  • 丰富的扩展能力:支持自定义插件开发

安装

npm install epoint-frontend-monitor-sdk --save
# 或者
yarn add epoint-frontend-monitor-sdk

基本使用

import { createMonitor } from "epoint-frontend-monitor-sdk";

// 创建监控实例
const monitor = createMonitor({
  appId: "your-app-id", // 应用ID,必填
  userId: "user-123", // 用户ID,可选
  reportUrl: "https://your-report-api.com/report", // 上报地址

  // 错误监控配置
  error: {
    enabled: true,
    jsError: true,
    resourceError: true,
    promiseError: true,
    httpError: true,
  },

  // 性能监控配置
  performance: {
    enabled: true,
    webVitals: true,
    firstPaint: true,
  },

  // 用户行为监控配置
  behavior: {
    enabled: true,
    pv: true,
    click: true,
    route: true,
  },
});

// 手动上报错误
monitor.reportError(new Error("自定义错误"));

// 手动上报性能指标
monitor.reportPerformance("customMetric", 123);

// 手动上报事件
monitor.reportEvent("buttonClick", { buttonId: "submit-btn" });

调试面板功能

SDK 集成了 eruda 调试面板,可通过 CDN 动态加载,减小 SDK 体积。调试面板有以下激活方式:

  1. 连续点击指定元素 N 次激活
  2. 通过 URL 参数打开

配置调试面板

import { createMonitor } from "epoint-frontend-monitor-sdk";

const monitor = createMonitor({
  appId: "your-app-id",
  // ...其他配置项

  // 调试面板配置
  debugPanel: {
    enabled: false, // 默认不启用,需要通过触发方式开启
    cdn: "https://cdn.jsdelivr.net/npm/eruda", // CDN地址
    triggerCount: 5, // 需要连续点击5次才能激活
    triggerEl: "body", // 点击触发的元素,默认是body
    triggerKey: "__debug_mode__", // localStorage中存储的键名
    urlParamKey: "debug", // URL参数名,如 ?debug=1
  },
});

激活方式

  1. 连续快速点击激活:在页面上连续快速点击配置的元素 (默认是 body) 指定次数 (默认 5 次)
  2. URL 参数激活:在 URL 后添加参数,例如 ?debug=1?debug=true
  3. URL 参数关闭:在 URL 后添加参数,例如 ?debug=0?debug=false

Console 控制功能

SDK 封装了原生 console 对象,可以通过配置控制日志输出:

import { createMonitor } from "epoint-frontend-monitor-sdk";

const monitor = createMonitor({
  appId: "your-app-id",
  // ...其他配置项

  // 控制台配置
  console: {
    enabled: true, // 是否开启console输出
    prefix: "[MyApp]", // 输出前缀
    enabledMethods: ["log", "warn", "error"], // 允许的方法,空数组表示全部
    saveToMemory: true, // 是否保存日志到内存
    maxMemoryLogs: 100, // 内存中最大保存的日志条数
    overrideNative: true, // 是否覆盖原生console
    logLevel: "info", // 日志级别: debug, info, warn, error, all
  },
});

控制 console 输出

通过 SDK 实例可以动态控制 console 输出:

import { ConsolePlugin } from "epoint-frontend-monitor-sdk";

// 获取monitor实例
const monitor = window.$monitor;

// 获取console插件
const consolePlugin = monitor.getPlugin(ConsolePlugin);

if (consolePlugin) {
  // 禁用所有console输出
  consolePlugin.disable();

  // 启用console输出
  consolePlugin.enable();

  // 设置日志级别
  consolePlugin.setLogLevel("warn"); // 只输出warn和error级别

  // 获取内存中的日志
  const logs = consolePlugin.getLogs();

  // 清空内存中的日志
  consolePlugin.clearLogs();

  // 恢复原始console行为
  consolePlugin.restore();
}
