干货 | 一份我的前端技术进阶指南

近十年来,前端的发展势头迅猛,每年都会出现不少新的技术和标准。「If you are not growing,then you are dying.」这句名言对于前端工程师同样适用。维持现状就是落后的开始,不断地学习才是必修课。




参与开源项目贡献的前提是你必须是项目的用户,并且在使用过程中遇到了问题。这样,你才有机会参与开源项目贡献。在遇到 bug 时不只提出 issue ,同时修改代码并且提交 pr,当 pr 被接受时,这个贡献才算完整。

为了达成这个目标,你不得不阅读这些项目的代码,作为此项目的用户,读清楚代码并且和业务相结合是最容易的,在这个过程中,吸收先进的写法和理念,提升会很快。在 pr 提交以后,会有项目成员 review 你的代码并给出修改意见,这是一个非常有意义的过程。那么问题来了,如何在现有的开源项目中找到一个 Bug ,又或者创建合理的特性呢?这还是需要一定功底的。所以说,参与开源项目贡献并不适合初学者提高技术能力。

下面说说造轮子。这也是不错的选择,但是,造出来的轮子很少会被使用在生产环境中,除非你的轮子真的独一无二 —— 因为对于一个项目来说,“稳”是排在第一位的。除了你的技术 Leader, 或许没有人会去关注项目中使用了哪些先进的技术和思想。

如果你的公司有基础建设部门,毫不犹豫的去那里吧,那就是造轮子的地方 —— 并且基本上都在使用原生技术,这里的每一个轮子都有可能变成开源项目。在这里,技术会得到大幅度提升。但是,如果本身技术一般,如何才能进入基础部门也是一个问题。那么就有了下面的内容。


对于 Web 前端工程师来说,前端包含两点,即「呈现」「业务」

对于呈现,那主要是 HTML CSS 的事情,现在大家的浏览器在解析文档方面基本上已经没有太大区别了,所以现在的原生前端开发者很少去关注浏览器兼容的事情,在这里所要做的就是记忆,不要求记住所有,但起码要知道它们都有什么特性,在有需求的时候就不会太过于慌乱。

对于业务,这里主要使用的是 Javascript (ECMAScript) 。既然是编程,在掌握基本语法的基础上还需要了解数据结构、算法、设计模式以及常见的编程范式,这些都是「起高楼」的基本功。




1. 先了解行业,掌握基础知识


2. 小试牛刀


3. 上手实践


4. 总结经验

步骤3 和 步骤4 是循环的过程,当经验足够多时,就可以进行下一步骤了。

5. 传道、授业、解惑


6. 巨大的质疑和迷惑



7. 创造者

Web 开发人员必备的错误监控平台—— FrontJS ,现已上线!


蒲公英基于网站开发及运营人员所需,其实也是在自身产品所需下,开发出一款集成性能监测与异常信息收集等功能的工具—— FrontJS。

什么是 FrontJS ?

FrontJS 是一款轻量级的网站性能及异常信息收集工具。最早是用于蒲公英旗下项目管理平台 Tracup ,也就是我们一个月前发布的 frontend-tracker (https://github.com/Pgyer/frontend-tracker ),发布后收获到一些良好反应。

FrontJS 可以被哪些人使用?

FrontJS 主要面向产品,运营,以及开发等的相关人员。

产品和运营人员可以通过页面分析功能来了解用户访问量、使用偏好、页面停留时间和用户流向等信息,从而对产品进行调整和优化;开发人员可以通过页面统计获取用户平均的页面统计信息做出 DOM 树渲染时间是否达标,DNS 解析时间是否达标,服务器响应时间是否达标等判断。当然,最主要的还是 JS 错误监控功能,我们会收集精细到 console.log 级别的任何 Javascript 异常信息并提供 stack trace 信息,同时我们还对每个 XHR 计时,帮助开发者判断某个 Endpoint 是否需要优化;对于加载的资源,我们会收集所有没有顺利加载出的资源的 URI;通过设置信任域,FrontJS 会收集页面内产生的跨域请求,这些信息可以帮助安全部门及时发现站点是否被添加了不信任的资源或者存在 XSS 的风险。

FrontJS 有哪些技术特点?

1. 图形界面配置,自动生成集成代码,即加即用;
2. JS 异常监控,包含 console 中的 log/warn/error 的收集;
3. 提供 API,可以对上报行为进行定制化的调整;
4. 具有包装后的 try – catch,可以产生自定义错误信息;
5. 资源监控,收集加载失败的资源以及跨域资源的 URI;
6. XHR 监控,收集 XHR 耗时、错误、超时、跨域等信息;
7. 自定义信任域,可以对跨域信息做出灵活调整有助于监控页面是否发生 XSS 或被植入病毒;
8. 页面性能监控,包含 DNS 时间, DOM 渲染时间等信息,可以组合计算出首屏时间以及白屏时间;
9. 事件流,可以了解异常发生时的上下文环境,帮助测试部门快速复现错误;
10. 近实时的分析结果。


1. 提供了包含错误收集,页面流向,性能分析,资源及请求监控等用户体验改进所需的信息;
2. 提供 API,甚至可以在错误信息中包含自定义信息;
3. 可以产生自定义错误,或者直接定义 Error 对象;
4. 对资源进行监控;
5. 对 XHR 进行监控;
6. 帮助安全人员发现潜在的 XSS 风险以及病毒植入风险。

FrontJS 如何使用?

光说不练假把式,现在我们就来一睹 FrontJS 的真容。

点击 https://www.frontjs.com/ 即可进入网站,登录后,界面很简单,开始点击「创建项目」输入「名称」,勾选完「行为」等,点击「保存」就可创建一个新的监测项目。将生成的代码添加到需要监测的网站上,那么在 FrontJS 项目内就能接收到相应的监测结果及数据。


首先是「概览」页面,展现了当前网站整体健康状况指示,包含网站脚本异常、资源异常、 XHR 异常及页面访问信息的时段性峰值和变化 ,可以帮助大家快速掌握问题发生的趋势,了解网站缺陷如何影响用户,指导网站改进计划。


接下来是「近 12 小时异常」汇总,分别从脚本、资源、XHR 方面收集展现,每一条信息都包含时间、反馈设备的详情、屏幕信息、IP 地址,并且汇总了该异常的出现总数。




另外针对用户访问, FrontJS 也会收集并提供一系列有关浏览器、操作系统、IP 地址等的访问数据,大家可以了解到所有用户的访问数、停留时间,基于大数据的统计浏览器种类和操作系统等。




总之, FrontJS 是一款技术人员必不可少的网页错误监控工具,修复问题、维护网站、改善用户体验,来 FrontJS 开启优化网页体验之旅吧。

填补了这个空白后,Tracup 真正实现了全端覆盖!

Tracup 又有大事件发生,继手机客户端、小程序后,Tracup 又迎来了桌面客户端的上线,真正实现了全端覆盖。


Tracup 桌面客户端分为 OS X 和 Windows 版本,支持 OS X 10.9 +, Windows 7 + 系统,点击这里可了解详情并下载。



下面是以 OS X 系统为例, Windows 系统按指引即可。

打开下载到桌面的 Tracup 安装包:


安装好后,我们就可以打开 Tracup 桌面客户端开始优质的工作体验啦。





比如 OS X 系统的 Command + Tab 键可以快速切换程序窗口,相较网页端打开多个不同页面更来得快捷。

另外, OS X 客户端还有个特点,就是打开后,在左上角菜单栏的每一栏有相应的快捷键。注意「项目」、「问题」、「窗口」这几个下方各操作的快捷键将有助于大家快速操作。







Tracup 更新 | 细分+清晰,问题动态中新增可添加附件


可能面对这样的更改,大家在第一时间体验还未适应,没关系,我们已经汲取了大家的反馈体验,在未来的更新中,我们将持续优化,以大家使用体验为第一位,让 Tracup 更好地为大家服务。






欢迎关注微信公众号「蒲公英开发者服务平台」,每周第一时间获取 Tracup 功能更新!




这不?连助力你、你们、企业团队 and every team 更好协作的 Tracup ,都坚持又升级了一波新技能。


熟悉 Tracup 的用户应该都知道, Tracup 在页面切换上之所以相当流畅,那是因为自开发之初,就集成了最新的编程技术:Angular js 。这使得即便是作为一款在线云协作平台的 Tracup ,在切换上也如桌面应用一样快速流畅。

但是如果因为这样,就“自傲自满”,也不是 Tracup 的风格。





我们将问题详情页面也进行了部分优化,对 UI 及功能布局做了相应调整,以让其展示更符合视觉体验。






让 Tracup 这些“技能”帮助你便利工作,让你专注傍身自己的更多技能,在工作中更游刃有余吧。
